The Ellensburg, WA sky for the week of December 27, 2025

Saturday: Red is a popular Christmas color. It is also a popular star color. And R Leporis, also known as Hind’s Crimson Star, is one of the reddest stars in the sky. It is a star near the end of its life that has burned its helium nuclei into carbon. Convective currents, like those in a pot of boiling water, bring this carbon to the surface. There it forms a layer of soot that scatters away the light from the blue end of the visible spectrum leaving the light from the red end of the spectrum to reach our eyes. For more information about Hind’s Crimson Star and a list of other deep red stars, go to https://utahdesertremote.com/hinds-crimson-star/. Hind’s Crimson star is one fist held upright and at arm’s length to the lower right of Rigel, the brightest star in Orion. You’ll need binoculars or a small telescope to see Hind's Crimson star. But you can easily spot Rigel two and a half fists held upright and at arm’s length above due southeast at 8:00 p.m.

Sunday: Saturn is three fists above the southeastern horizon and Jupiter is two and a half fists above the eastern horizon at 8:00 p.m.

Monday: Mercury is just above the southeastern horizon at 7:15 a.m.

Tuesday: The moon, the planet Uranus, and the open star cluster called The Pleiades make a small equilateral triangle, six and a half fists above due south at 9:00 p.m. The Pleiades has about two dozen stars easily visible with binoculars. It is to the left of the moon. Uranus is to the lower left of the moon.

Wednesday: Aside from the Big Dipper, the northern sky doesn’t get enough love. Vega, the bright star in the constellation Lyra, is one fist above due northwest at 8:00 p.m.

Thursday: Today is the day we celebrate the anniversary of something new – a new classification of celestial objects. Giuseppe Piazzi discovered Ceres [pronounced sear’-ease], the first of what are now called “asteroids”, on January 1, 1801. Ceres is the largest asteroid in the belt between Mars and Jupiter. At first, Piazzi thought it was a star that didn’t show up on his charts. But he noted its position changed with respect to the background stars from night to night. This indicated to him that it had to be orbiting the Sun. The International Astronomical Union promoted Ceres to the status of “dwarf planet” in August of 2006.

Friday: The first prominent meteor shower of the year occurs this weekend. Meteor showers are tiny rocks that mostly burn up in the atmosphere. Do you wonder what would happen if larger rocks hit the surface of the Earth? Well, wonder no more. The browser-based app called Asteroid Launcher will simulate the collisions. You select the asteroid type, size, speed, and angle of impact. The most common impactor material is stone, and the typical speed is 40,000 miles per hour, in case you want to introduce some realism into your simulation. Go to https://neal.fun/asteroid-launcher/, click on the map where you want the asteroid to land and then launch your virtual asteroid.

The Ellensburg, WA sky for the week of December 20, 2025

Saturday: Just before Christmas, you look for junk to clean out of your closets so you can re-gift it. I mean, so you can throw it out or recycle it. NASA and other agencies are monitoring thousands of space junk pieces. Some of this junk is dangerous. The International Space Station occasionally performs debris avoidance maneuvers to keep its panels and sensitive instruments safe. NASA has produced simulations to help you visualize the amount of space junk at https://svs.gsfc.nasa.gov/5258.

Sunday: At 7:00 a.m., Pacific Standard Time, the Sun reaches its lowest point in the sky with respect to the background stars. This point is called the Winter Solstice. During the day that the Sun reaches this point, your noontime shadow is longer than any other day of the year. Also, the Sun spends less time in the sky on the day of the Winter Solstice than any other making this the shortest day of the year. Even though it is the shortest day of the year, it is not the day with the latest sunrise or the earliest sunset. The latest sunrise is during the first week of January and the earliest sunset is during the second week in December. The Sun is at its southernmost point with respect to the background stars on the day of the winter solstice. This means the Sun spends the least amount of time above the horizon on that day. However, the Sun's rise and set times depend on more than its apparent vertical motion with respect to the background stars. It also depends on where the Sun is on the analemma, that skinny figure-8 you see on globes and world maps. During the second week in December, the Sun is not quite to the bottom of the analemma. But it is on the first part of the analemma to go below the horizon. During the first week of January, it is on the last part of the analemma to rise above the horizon meaning that’s when we have the latest sunrises.

Monday: Mercury is less than half a fist held upright and at arm’s length above the southeastern horizon at 7:00 a.m.

Tuesday: One of the biggest astronomy stories of the year was the discovery of 128 new moons orbiting Saturn, bringing its total to 274, the most in the Solar System. Learn more about the discovery here: https://www.youtube.com/shorts/aoNSJlzH6hU. Learn more about Saturn by looking three and a half fists above the south-southwestern horizon at 7:00 p.m.

Wednesday: The bright star Altair is one fist above due west at 7:00 p.m.

Thursday: Where is the one who has been born King of the Jews? We saw Jupiter being eclipsed by the Moon in the east and have come to worship him” (Matthew 2:2, Bruce Palmquist version, informed by Michael Molnar). There are many theories as to the physical explanation of the Star of Bethlehem, the celestial object that guided the wise men to the location of Jesus. Some people think it was a recurring nova, a star that explodes. Some think it was a close alignment of bright planets. Some think it was a miracle that requires no physical explanation. In 1991, astronomer Michael Molnar bought an ancient Roman Empire coin that depicted a ram looking back at a star. Aries the ram was a symbol for Judea, the birthplace of Jesus. The Magi, or “wise men”, who visited the baby Jesus practiced astrology and would have been looking in that region of the sky for the king prophesied in the Old Testament. Molnar, a modern-day wise person, used sky simulation software to model the positions of planets and the Moon in the region of Aries. According to his model, Jupiter was eclipsed, or blocked, by the Moon on the morning of April 17, 6 BC. A book written by the astrologer of Constantine the Great in 334 AD supports Molnar’s theory. The book describes an eclipse of Jupiter in Aries and notes a man of divine nature born during this time. See https://goo.gl/o89A4o for more information.

Libra, Jupiter, and the moon are visible at 7:00 tonight. The moon is three fists above the southwestern horizon, Aries is six fists above the south-southeastern horizon, and Jupiter is one fist above the east-northeastern horizon.

Friday: Did you get a telescope or binoculars for Christmas? The next item on your list should be a sky watching app for your phone. These apps will help you to get familiar with the constellations and bright stars. Then you can zoom into an area of interest and learn about objects that are visible through your telescope. I like SkySafari, a free app or low-cost iPhones app (depending on their promotions at the time). But there are many other good ones to choose from for little or no money. Go to https://www.lifewire.com/best-stargazing-apps-5086553 for seven short reviews. One of your first targets should be the Pleiades open star cluster. It is bright, easy to see with the naked eye and even more interesting in binoculars. It is six fists above due southeast at 8:00 p.m.

The Ellensburg, WA sky for the week of December 13, 2025

Saturday: The Geminid meteor shower peaks tonight and tomorrow morning. Meteor showers are named after the constellation from which the meteors appear to originate. These meteors appear to come from a point in Gemini the twins. This point is about four fists held upright and at arm’s length above due east at midnight tonight. You can follow this point throughout the night, as it will remain near Gemini and the planet Jupiter. By 4:00 a.m., it is four fists above the southwestern horizon. This shower is typically one of the best ones of the year, producing bright, medium speed meteors with up to 80 meteors per hour under ideal conditions near the peak. This year, the moon will be in the waning crescent, leaving the sky dark enough to see the dimmer meteors.

Most meteor showers occur when the Earth passes through the orbital trail of a comet. The broken off comet fragments collide with the Earth and burn up in the atmosphere. Astronomers had searched for a comet source for this shower since 1862 when the shower was first observed. Finally, in 1983, astronomers discovered the object that created the fragments that cause this meteor shower each year. To their surprise, it was a dark rock that looked like an asteroid, not a shiny icy comet. Astronomers named this object Asteroid 3200 Phaethon. For more information about the Geminid shower, go to https://goo.gl/f4qMqg.

Sunday: Are you disappointed because you are not going anywhere for the holidays? Why not take a (virtual) trip to outer space using Google’s visualization tool called 100,000 Stars. It shows the stars in our neighborhood in a very good 3-D simulation. The Sun is initially at the center. If you zoom in, you can click on neighboring stars and learn more about them. Go to http://stars.chromeexperiments.com/ for the simulation. It works best on a Chrome browser.

Monday: One of those stars in our neighborhood, the bright star Sirius, is one and a half fists above due southeast at 10:00 p.m.

Tuesday: Mercury is a half a fist above the southeastern horizon at 6:45 a.m.

Wednesday: Today is the start of the Saturnalia celebration, an ancient Roman festival in honor of their god Saturn, the god of agriculture and time. The holiday featured a break from work and school, a public banquet, and private gift giving. Some of these customs influenced the secular aspects of Christmas celebrations. For example, after Sheldon hugged Penny on The Big Bang Theory, Leonard proclaimed, “It’s a Saturnalia miracle” https://youtu.be/yarNJnZw2yk. It would not be a miracle if you saw the planet Saturn today. It is four fists above due south at 6:00 p.m.

Thursday: With the Sun as low as it gets in the Northern Hemisphere winter sky this weekend, you may wish it was a little more prominent. Every orbit, NASA’s Parker Solar Probe has a close encounter with the Sun. Its last close encounter was in mid-September, the closest one yet, passing just 3.8 million miles from the solar surface. It passed through the boundary between outer space and the region where the Sun’s magnetic field has a tight hold on the plasma that makes up the outer layer of the Sun. Since the Sun does not have a solid surface, this is as close to touching the Sun as an object can get. It is analogous to “touching” a cloud. The cloud does not have a definite surface but there is a boundary between “cloud” and “not cloud”. For more about the mission plus short videos, go to http://parkersolarprobe.jhuapl.edu/.

Friday: The southernmost bright star visible in the northern USA is one fist over the south-southwestern horizon at 7:00 p.m.

The Ellensburg, WA sky for the week of December 6, 2025

Saturday: Imagine Opie and Andy Taylor walking down the dirt path at night to that fishing hole in the sky. They’d probably be looking to catch Pisces, the two fish already conveniently tied together with two ropes. The ropes are connected at the star Alrescha, Arabic for “the cord”. Alrescha is four and a half fists held upright and at arm’s length above due south at 8:30 p.m. The fish are attached to lines of stars that branch out at one o’clock and three o’clock from Alrescha. By the way, “The Fishing Hole”, The Andy Griffith Show’s theme song, was rated the 20^th best TV theme song of all time by ign.com. That’s too low of a ranking in my opinion.

Sunday: Mercury will be as far away from the Sun in the sky as it will get this orbital cycle. This "farthest away" point is known as the planet's greatest elongation. Since Mercury is in the morning sky, it is west of the Sun, and this occurrence is called the greatest western elongation. This morning, Mercury is nearly one fist above the southeastern horizon at 6:45 a.m. Over the next few weeks, Mercury will move toward the Sun in the sky. By mid-February, it will be visible in the evening sky.

Monday: The bright star Capella is nearly straight overhead at midnight.

Tuesday: Regulus is less than half a fist to the upper right of the moon at 11:00 p.m. Both are about a fist above the eastern horizon.

Wednesday: The earliest sunset of the year in Ellensburg occurs at 4:14 p.m. today. This seems odd because the shortest day of the year, the winter solstice, isn’t for about two more weeks. The Sun is at its southernmost point with respect to the background stars on the day of the winter solstice. This means the Sun spends the least amount of time above the horizon on that day. But the sunrise and sunset times depend on more than the Sun’s apparent southward motion in the sky. It also depends on where the Sun is on the analemma, that skinny figure-8 you see on globes and world maps. During the second week in December, the Sun is not quite to the bottom of the analemma. But it is on the leading edge of the analemma, the first section to go below the horizon. For a slightly better explanation of this, including a diagram, go to https://go.shr.lc/2NOMOQC. Or just go watch the sunset. But don’t stare at the Sun.

Thursday: While the days are getting shorter, the nighttime sky is actually getting brighter due to the greater use of low energy LED bulbs. While these bulbs use much less energy than incandescent or compact fluorescent bulbs, researchers think that people and communities are using more of the bulbs and leaving them on longer. This is increasing light pollution near cities. You can get more illumination on the subject at https://www.latimes.com/environment/light-pollution-latt-123.

Friday: At 9:00 p.m., Saturn is three fists above due southeast and Jupiter is two and a half fists above the eastern horizon.

The Ellensburg, WA sky for the week of November 29, 2025

Saturday: Saturn is about a fist held out at arm’s length to the lower right of the moon at 9:00 p.m. At this time, Jupiter is about one fist above the east-northeastern horizon.

Sunday: Is your favorite astronomy-loving relative asking for a telescope this Christmas? Before reaching for your credit card, read this guide to choosing your first telescope, available at http://goo.gl/5oXmGj. If cost is an issue, look no further than this article about low cost telescopes https://goo.gl/8yyddy. These are not cheap telescopes. They are simple, low-cost, easy to use telescopes that your future astronomer will still use for quick observing sessions long after she has purchased a much larger instrument for richer viewing. If you want to give a gag astronomy gift to someone who really bugs you, give them a copy of this column. After such a dud “gift”, you’ll never hear from them again. And that may be the best gift of all.

Monday: Have you been online shopping all weekend? Do you need an evening sky break? You deserve a big reward so make it a double. A Double Cluster, that is. The Double Cluster, also known as h and Chi Persei, consists of two young open star clusters in the constellation Perseus. Of course, young is a relative term as these clusters are about 13 million years old. Each cluster is spread out over an area about the same size as the full moon. To the naked eye, the Double Cluster shines with a steady, fuzzy glow. Binoculars resolve dozens of individual stars in the clusters. The Double Cluster is five and a half fists above the northeastern horizon at 6:00 p.m., about a fist below the sideways “W” of Cassiopeia and three fists above the bright star Capella.

Tuesday: Mercury is one fist above the southeast at 6:45 a.m.

Wednesday: It’s getting too cold to see frogs in the wild. But this is a great time to see frogs in the sky. Ancient Arabs referred to the stars that we now call Fomalhaut and Diphda as Ad-difdi al-awwal and Ad-difda at-tani. This means the first frog and the second frog, respectively. Both frogs are low in the southern sky at 6:00 p.m. Fomalhaut is nearly one and a half fists above due south. The slightly dimmer Diphda is two fists above the south-southeast horizon.

Thursday: Tonight’s December full moon is called the Cold Moon… for obvious reasons. On the evening of a full moon, the moon rises as the Sun sets, reaches its highest point in the sky in the south at midnight, and sets as the Sun rises.

Friday: The bright star Vega is four and a half fists above the western horizon at 6:00 p.m.

The Ellensburg, WA sky for the week of November 22, 2025

Saturday: We are just a few days away from the earliest sunsets of the year in Ellensburg, meaning it is getting dark as early as possible. (No, the earliest sunsets are not on the first day of winter.) Thus, it is a good time to learn how to quantify the darkness of the sky. First find the Great Square, the main part of the constellation Pegasus. It is six fists held upright and at arm’s length above due south at 7:30 p.m. Find the dimmest star that you can see inside or near the square. Then compare that star to the chart at  https://www.skyandtelescope.com/observing/how-dark-is-your-night-sky/. The larger the magnitude number, the dimmer the star. When the sky is exceptionally dark, you can see more stars and more interesting deep-sky objects such as star clusters and nebulae.

Sunday: Venus is just above the east-southeastern horizon at 6:30 a.m.

Monday: “Hey baby! What’s your sign?”

“Ophiuchus, of course”

The Sun is in the same part of the sky as the stars of Ophiuchus from this week to mid December. This is what astrologers mean when they say the Sun is “in” a constellation. Thus, if you were born between these dates, you should be an Ophiuchus. The fact that the horoscopes never list Ophiuchus is a major flaw of astrology. Astrology says that some of our characteristics are based on the location of the Sun at our birth. How can astrologers leave out three weeks from their system? That is like a scientist saying she can explain the results of her experiment every month of the year except in early December. Ophiuchus was a mythical healer who was a forerunner to Hippocrates. According to myth, he could raise people from the dead. Maybe that is why he is ignored by astrology. Raising people from the dead is much less impressive than giving spot-on advice such as “Today is a good day to watch your finances.”

The bright stars of Ophiuchus rise just before the Sun. Rasalhague (pronounced Ras’-al-hay’-gwee), the brightest star, is just above the east-northeastern horizon at 6:30 a.m.

Tuesday: Deneb Kaitos, Arabic for whale’s tail, is two and a half fists above due south at 8:30 p.m. This is the brightest star in the constellation Cetus the sea monster. Or, if you are less prone to hyperbole, Cetus the whale.

Wednesday: Lacerta, the faint lizard constellation, is straight overhead at 6:00 p.m. It was named by the Polish astronomer Johannes Hevelius in 1687 to fill the space between the much brighter and well-defined constellations Pegasus, Andromeda, Cassiopeia, Cepheus, and Cygnus going clockwise from the constellation just south of Lacerta.

Thursday: Some of us have a lot to be thankful for on Thanksgiving. But probably not as much as Andromeda had to be thankful for. According to Greek mythology, the beautiful princess Andromeda was chained to a rock next to the ocean. Cetus the sea monster was about to devour her in order to punish her family. Her mother Queen Cassiopeia and her father King Cepheus didn’t know what to do. It seemed that all was lost. But along came Andromeda’s boyfriend, the great warrior Perseus. Even though Perseus’ standing as the son of King Zeus and the slayer of Medusa was probably enough to win Andromeda under normal circumstances, Andromeda’s impending death-by-sea-monster was not a normal circumstance. So, Perseus drove his sword into the sea monster’s neck and killed it. This was the first time in recorded history that a set of parents actually welcomed an uninvited Thanksgiving visit from the boyfriend. Perseus is about five fists above the east-northeastern horizon and Andromeda is about seven fists above the east-southeastern horizon at 7:00 p.m.

Friday: Saturn is about a fist to the upper left of the moon at 9:00 p.m. At this time, Jupiter is about one fist above the east-northeastern horizon.

The Ellensburg, WA sky for the week of November 15, 2025

Saturday: Lieutenant Worf, the Klingon Starfleet officer on Star Trek: The Next Generation, might say “Today is a good day to die.” But Deneb, the bright supergiant star in Cygnus the Swan would say “two million years from now is a good day to die.” This may seem like a long time. But, compared to the lifespan of most stars, two million years from now is as close as tomorrow. For example, the Sun will last about five billion years. Small stars known as red dwarfs may last trillions of years. Prepare your astronomically short goodbyes to Deneb tonight at 6:30 o’clock when it is seven and a half fists held upright and at arm’s length above due west.

Sunday: The Leonid meteor shower peaks tonight and tomorrow morning. There will be increased activity for the next few days. These meteors appear to come from a point in the constellation Leo the lion. This point is about five and a half fists above the southeastern horizon at 5:00 a.m. The Moon is close to new, so it won't interfere with the dimmer meteors. The Leonid meteors are particles from the tail of Comet Tempel-Tuttle, a comet discovered by Ernst Tempel and Horace Parnell Tuttle in 1866. These are exceptionally fast-moving meteors – over 150,000 miles per hour! Go to https://earthsky.org/astronomy-essentials/everything-you-need-to-know-leonid-meteor-shower/ to read everything you need to know about the Leonid meteor shower. As your mother might say, dress warmly and sit in a comfortable chair for maximum enjoyment.

Monday: “It’s a wonderful day in the neighborhood.” Constellations can be considered neighborhoods in the nighttime sky. But the stars in those constellations are not necessarily neighbors in real life. For example, the bright stars in the constellation Cassiopeia range from 19 light years to over 10,000 light years away from Earth. One constellation that consists of real neighbors is Ursa Major. Or, more specifically, the Big Dipper. Five stars in the Big Dipper are all moving in the same direction in space, are about the same age, and are all about 80 light years from Earth. “Please won’t you be my neighbor?” Skat, the third brightest star in the constellation Aquarius is a neighbor to these five Big Dipper stars, all of which are about 30 light years from each other. They are thought to have originated in the same nebula about 500 million years ago. Just like human children do, these child stars are slowly moving away from home. Skat is about three fists above due south at 7:00 p.m. The much brighter Fomalhaut is a fist and a half below Skat. And it’s not fun being below Skat.

Tuesday: At 6:30 a.m., Venus is to the lower left of the waning crescent just above the east-southeastern horizon.

Wednesday: Are you thankful that you live in a solar system with multiple planets? You should be. A giant planet like Jupiter cleans up planetary debris that could have collided with Earth and hindered the formation of complex life. Any inhabitants of the planets orbiting Upsilon Andromedae are thankful for this, as well. Upsilon Andromedae, a star in the constellation Andromeda, was the first Sun-like star discovered to have multiple planets orbiting it. So far, all its discovered planets are giant planets like Jupiter. But the system is likely to also contain smaller planets. The dim star, but certainly not its planets, is barely visible overhead at 10:00 p.m. Our Jupiter is one and a half fists above the eastern horizon at this time.

Thursday: Saturn is nearly four fists above due south at 7:30 p.m.

Friday: Have you ever sat around waiting for a long-distance call from another state? Another country? How about another star system? In 2019, astronomers thought they heard a radio signal from a planet orbiting Proxima Centauri, our Sun’s nearest neighbor at about 4.2 light years away. This signal showed many signs of being extraterrestrial in origin, including coming from a specific location in the sky, having a pure tone, and changing in frequency like something moving exactly towards or exactly away from the Earth. However, an analysis two years later showed that the signal was more like a crank call. Read more about the discovery and undiscovery at https://skyandtelescope.org/astronomy-news/the-true-nature-of-the-candidate-et-signal-from-proxima-centauri/. Proxima Centauri is part of the three-star Alpha Centauri system, the third brightest star in the sky. You need to go down to the southern tip of Texas or Florida to see Alpha Centauri.

The Ellensburg, WA sky for the week of November 8, 2025

Saturday: The Northern Taurid meteor shower peaks tonight after midnight. These are slow moving meteors that result in the occasional fireball. The Taurid meteor showers produce a few bright meteors every hour. The Waning Gibbous Moon will obscure the dim meteors. These meteors appear to come from a point in Taurus the bull, near the open star cluster called the Hyades. This point is about six and a half fists held upright and at arm’s length above the southern horizon at midnight. You can follow this point throughout the night, as it will remain one and a half fists to the right of the V-shaped Hyades Cluster with its bright star Aldebaran (pronounced Al-deb’-a-ran). In case you miss them tonight, there will be increased meteors until December 2. Meteors are tiny rocks that burn up in the atmosphere when the Earth runs into them. The source of this shower is the asteroid 2004 TG10. Go to https://earthsky.org/astronomy-essentials/taurid-meteors-all-you-need-to-know/ for more information.

Sunday: While Stonehenge is an ancient burial ground visited by religious people for thousands of years, MIThenge is an 825-foot-long hallway on the campus of the Massachusetts Institute of Technology visited by the Sun’s rays twice a year. Every year in November and January, the setting Sun lines up with a narrow window at the end of the long hall and the light shines down to the opposite end. This season’s alignment is from November 9-11 at about 4:20 pm. For more information, visit http://goo.gl/0hwFQf or visit MIT. While you are at it, challenge yourself to find a similar alignment in your neighborhood.

Monday: Jupiter and the moon are about six fists above the southwestern horizon at 6:15 a.m. Jupiter is to the lower right of the moon. Venus is half a fist above the east-southeastern horizon at this time.

Tuesday: Are you planning to open your Martinmas gifts today? Martinmas is a holiday in many parts of the world commemorating Saint Martin of Tours. He was buried on November 11, 397. What does this have to do with astronomy? Not much except that the celebration on November 11 often doubles as a cross-quarter day celebration, a day that is halfway between an equinox and a solstice. Also, according to an agricultural calendar, November 11 marks the practical beginning of winter.

Wednesday: Lieutenant Worf, the Klingon Starfleet officer on Star Trek: The Next Generation, might say “Today is a good day to die.” But Deneb, the bright supergiant star in Cygnus the Swan would say “two million years from now is a good day to die.” This may seem like a long time. But, compared to the lifespan of most stars, two million years from now is as close as tomorrow. For example, the Sun will last about five billion years. Small stars known as red dwarfs may last trillions of years. Prepare your astronomically short goodbyes to Deneb tonight at 7:00 o’clock when it is seven fists above the western horizon.

Thursday: Saturn is three fists above the southeastern horizon at 6:00 p.m.

Friday: Along with the not-so-subtle drug reference in their name, The Doobie Brothers could have made an astronomy reference in their song lyrics if they would have written: “Old Earth water, keep on rollin’, Mississippi moon won’t you keep on shining on me.” Astronomers now think that some of the water on Earth may be older than the Solar System. The chemical signature of the water indicates it came from a very cold source, just a few degrees above absolute zero. The early Solar System was much warmer than this, meaning the water came from a source outside the Solar System. For more information about the old Earth water, go to https://www.skyatnightmagazine.com/news/earth-water-formed-billions-years-ago-before-sun.

The Ellensburg, WA sky for the week of November 1, 2025

Saturday: Happy Celtic New Year! Many historians think that November 1, known for the festival of Samhain, was the ancient Celtic New Year’s Day. Samhain, Old Irish for “summer’s end”, was a harvest festival that may have contributed to some of the customs of our current “holiday” of Halloween. Celebrate the Celtic New Year by observing Saturn in the southeastern sky, about a half fist held upright and at arm’s length to the lower left of the moon at 7:00 p.m.

Before you fall back on your bed tonight, set your clock back one hour to the real time. Daylight Saving Time ends early Sunday morning at 2:00 a.m. This means one more hour of sky watching in the evening because the Sun will set one hour earlier. Ben Franklin proposed the idea of “saving daylight” by adjusting our clocks way back in 1784. Daylight Saving Time was first utilized during World War I to save electricity. After the war, it was abandoned. It was reintroduced during World War II on a year-round basis. From 1945 to 1966, some areas implemented daylight saving and some did not. Also, it was not implemented with any uniformity as to when it should start and stop. The Uniform Time Act of 1966 codified the daylight saving rules. It also banished the “s” as the correct term is daylight saving time, not daylight savings time.

Sunday: Jupiter is one and a half fists above the east-northeastern horizon at 11:00 p.m. That means that Jupiter’s moons can be seen tonight, as well. In 2022, NASA’s Juno spacecraft sent back some of the most detailed images of Jupiter’s icy moon Europa. For more about the images and the rest of Juno’s mission, go to https://www.jpl.nasa.gov/news/nasas-juno-gets-highest-resolution-close-up-of-jupiters-moon-europa.

With a small telescope, you will be able to see all four of Jupiter’s largest moons tonight. Europa is about two Jupiter diameters to the upper right of Jupiter. Io, the closest of the bright moons to Jupiter, is about one Jupiter diameter to the lower left of Jupiter. Ganymede, the largest moon in the solar system, is about another Jupiter diameter beyond Io. Callisto, the farthest of the bright moons from Jupiter, is another three Jupiter diameters beyond Ganymede. Depending on the orientation and design of your telescope, these directions may be flipped. If your viewing conditions are excellent, you can see some of the moons with binoculars.

Monday: The two meteor showers centered in the constellation Taurus peak this week and next. That means there will be increased meteor activity in western Taurus.

The Southern Taurid meteor shower peaks for the next three nights. These are slow moving meteors that result in the occasional fireball. The Taurid meteor showers produce a few bright meteors every hour. The bright moon will obscure all but the brightest meteors through the end of the week. These meteors appear to come from a point in Taurus the bull, about two fists held at arm’s length to the right of the open star cluster called the Hyades. This point is about five fists above the south-southeast horizon at midnight. The “V” of the Hyades cluster points at the center of the Southern Taurid shower. Meteors are tiny rocks that burn up in the atmosphere when the Earth runs into them. These rocks are broken off parts of Comet 2P/Encke. Go to https://earthsky.org/astronomy-essentials/taurid-meteors-all-you-need-to-know/ for more information.

Tuesday: You’ve seen all the top 100 lists: top 100 ways to squat, top 100 Indonesian astronomers, etc. Now get excited for this week’s full Moon by reading about and finding some of the lunar 100. Go to http://goo.gl/ldGvH6. This list describes 100 interesting landmarks on the Moon that are visible from Earth. They are listed from easiest to see, starting with the entire moon itself at number 1, to most difficult (Mare Marginis swirls, anyone?). Stay up all night to binge watch the moon or just make a few observations a month. It’s your decision. It’s our moon. Start your viewing tonight at 7:00 p.m. when the Full Moon is three fists above the eastern horizon. I suggest starting with Mare Crisium, the circular, dark, basaltic plain in the upper right-hand portion of the moon. Items such as Crisium were named "Mare" by early astronomers who mistook them for seas, instead of the hardened lava beds that they really are.

Wednesday: Venus is a half a fist above the east-southeastern horizon at 6:00 a.m.

Thursday: Fomalhaut is one and a half fists above due south at 8:00 p.m.

Friday: Procyon, the brightest star in Canis Minor, the smaller dog, is one fist above due east at 11:00 p.m. Procyon means “before the dog” in ancient Greek, a fitting name because it always rises a few minutes before Sirius, nicknamed “the dog star”.

The Ellensburg, WA sky for the week of October 25, 2025

Saturday: Halloween is this Friday. If you need costume ideas, look low in the sky at 7:15 p.m. Arcturus is about one fist held upright and at arm’s length above the western horizon. In The Hitchhiker’s Guide to the Galaxy, Arcturus is home to giant ships called Arcturan Megafreighters and oversized megafauna like the Arcturan Megaleech and Arcturan Megacamel. Capella is about one fist above the northeastern horizon. In the second season episode of Star Trek: The Original Series called Friday’s Child, the Enterprise goes to Capella IV to negotiate a mining contract for a valuable mineral. While there, they get tangled up with warring factions and a Klingon. Inspiration from these two stars might help you win the costume contest as you go dressed as Captain Kirk, a Klingon, or an Arcturan Megaleech. For more about stars and planets featured in popular fiction, go to https://en.wikipedia.org/wiki/Stars_and_planetary_systems_in_fiction.

Sunday: Saturn is three fists above due southeast at 8:00 p.m.

Monday: According to the “One world, group hug, love everyone” philosophy, political borders are human-made and can’t be seen from space so why can’t we all just get along. According to real world pragmatic discoveries, some human-made political borders CAN be seen from space. Since 2003, India has illuminated its border with Pakistan to prevent illegal crossings. In 2011, astronaut Ron Garan took a picture of that border from the International Space Station. For more information, including the photo, go to http://goo.gl/mY8xG.

Tuesday: Did you know that moons and dwarf planets share some similar features? The five largest moons of Uranus have the same heat signatures as the largest dwarf planets such as Pluto and Eris. That means they are relatively dense and don’t immediately radiate away all their daytime-absorbed heat at night. Read more about Uranian moons at https://skyandtelescope.org/astronomy-news/uranian-moons-are-like-dwarf-planets/. Uranus can easily be seen with typical binoculars. It is about a half a fist to the lower right of the open star cluster called the Pleiades. Move the Pleiades to the upper left of your binoculars field of view. Uranus will be on the lower right. Uranus is the object that will have moved over the course of a few nights.

Wednesday: Mercury will be as far away from the Sun in the sky as it will get this orbital cycle. This "farthest away" point is known as the planet's greatest elongation. Since Mercury is in the evening sky, it is east of the Sun, so this occurrence is called the greatest eastern elongation. Mercury is right above the southwestern horizon at 6:15 p.m. Over the next two weeks, Mercury will move toward the Sun in the sky. By late November, it will be visible in the morning sky.

Thursday: At 7:00 a.m., Venus is about half a fist above the east-southeastern horizon and Jupiter is six fists above the south-southwestern horizon.

Friday: Halloween weekend is a great time to celebrate the dead. Dead stars, that is. Black holes and neutron stars are the end of life for super massive stars. But intermediate mass stars such as our Sun end up as white dwarfs. After fusing hydrogen into helium for most of its life and fusing helium into heavier elements for a brief period at the end of its life, the Sun will end up with a core of heavier elements that can no longer produce energy through nuclear fusion. Without the outward radiation pressure from fusion energy resisting the inward pull of gravity, the Sun will end up as a super-dense sphere of atoms in which the electrons are squished onto the nuclei. It will be an object with nearly all its mid-life mass but in a volume about the size of the Earth. The easiest white dwarf to see is in the triple star system called Keid, from the Arabic word “qayd” meaning eggshells. Learn more about Keid, also called 40 Eridani, including map of how to find it at

https://www.skyandtelescope.com/observing/trick-or-treat-with-white-dwarfs/. At midnight (scary), Keid is two and a half fists above due southeast. You’ll need a small telescope to see it. First find Rigel, the brightest star in the constellation Orion. It is one and a half fists above the east-southeastern horizon. Then use binoculars to find the right area. With Rigel at the bottom of your field of view. There should be a star near the top of your girls of view that is about one sixth as bright. This star is called Cursa. Next, move your binoculars up and to the right about one and a half field of view diameters. Look for two stars close together, each about one third as bright as Cursa. Finally, move your binoculars straight over to the right about one and a half field of view diameters. The lower of these two stars is Keid or 40 Eridani A. You’ll need a telescope to see the white dwarf, called 40 Eridani B.

The Ellensburg, WA sky for the week of October 18, 2025

 Saturday: Comet Lemmon (C/2025 A6) is still shaping up to be one of the brightest comets of the year. At 8:00 p.m., it is to the left of the star Cor Caroli, about one and a half fists above the northwestern horizon. You can also follow along the curve of the Big Dipper handle with binoculars. When you get to the end of the handle, move your binoculars downward towards the northwestern horizon. There is an interactive sky map at https://theskylive.com/c2025a6-info.

Sunday: The constellation Vulpecula, the little fox, stands nearly six fists held upright and at arm’s length above due southwest at 9:00 p.m. It is in the middle of the Summer Triangle, which is defined by the bright stars Vega, Deneb, and Altair. First find Deneb, the bright star nearly straight overhead. It is at the tail of the constellation Cygnus the swan. Move your eyes down towards the horizon and through the long neck of the swan. The fox is so faint that you need very dark skies to see it. While dim, it has a lot to offer astronomers. The first pulsar ever discovered is in Vulpecula. So is one of the closest extrasolar planets with water in its atmosphere.

Monday: The Orionid meteor shower consists of the Earth colliding with pieces of the remains of Halley's Comet's tail. This shower peaks after midnight tonight until dawn tomorrow. This is not a meteor shower that typically results in a meteor storm. There will be about 15-20 meteors per hour, many more meteors than are visible on a typical night but not the storm that some showers bring. The Moon will be new, meaning dark skies and good viewing for the entire night. Meteor showers are named after the constellation from which the meteors appear to originate. These meteors appear to come from a point in Orion, the hunter. This point is about one fist held upright and at arm’s length above due east at midnight. You can follow this point throughout the night as it will remain one fist above the prominent reddish star Betelgeuse (pronounced Bet'-el-jews). The Orionid meteors are fast - up to 40 miles per second. If you fall asleep tonight, you can catch the tail end of the shower every night until early November. For more information, go to https://earthsky.org/?p=27937.

Tuesday: Saturn is three fists above the southeastern horizon at 8:30 p.m.

Wednesday: Venus is about a half a fist above the eastern horizon at 6:30 a.m. Jupiter is six fists above the southern horizon at this time.

Thursday: What time is teatime? Certainly not during an autumn evening. The constellation Sagittarius the archer, with its signature teapot shape, is sinking into the southwestern horizon. By 8:00 p.m., the handle is on top, and the spout is touching the horizon ready to pour that last cup of tea.

Friday: Halloween is a week from today so make sure you load up on peanut clusters, almond clusters, and open star clusters this week. That last one will be easy (and cheap… actually free) because two of the most prominent open star clusters in the sky are easily visible in the autumn sky. The sideways V-shaped Hyades Cluster is two fists above due east at 10:00 p.m. Containing over 300 stars; the Hyades cluster is about 150 light years away and 625 million years old. The Pleiades Cluster is a little more than three fists above due east. It has three times as many stars as the Hyades Cluster and is younger. Compared to our 5-billion-year-old Sun, the 100-million-year age of the Pleiades is infant-like.

The Ellensburg, WA sky for the week of October 11, 2025

Saturday: “I’m a little teapot, short and stout. The galactic center, I pour it out.” (I’m a Little Teapot, astronomy version, 2025.) Despite its enormous size and importance, the center of our Milky Way galaxy and its giant black hole remain hidden to the naked eye behind thick clouds of gas and dust. By plotting the orbits of stars near the middle of the galaxy, astronomers have determined that the black hole’s mass is equal to about 4.5 million Suns. While you can’t see the actual galactic center, you can gaze in the direction of the center by looking just to the right of the teapot asterism in the constellation Sagittarius. This point is about a half a fist above the south-southwestern horizon at 8:00 p.m., in line with the moon in the sky.

Sunday: It is good to plan ahead so start thinking about the Orionid meteor shower. This shower, which consists of the earth colliding with pieces of the remains of Halley's Comet's tail, peaks on the morning of October 21 but produces meteors from early October until early November. These meteors appear to come from a point in Orion, the hunter. This point is about one fist above the eastern horizon at midnight. You can follow this point throughout the night as it will remain near the prominent reddish star Betelgeuse (pronounced Bet'-el-jews). The Orionid meteors are fast - up to 40 miles per second. For more information about the Orionids, go to https://earthsky.org/?p=27937.

Monday: Saturn is three fists above due southeast at 9:00 p.m.

Tuesday: Jupiter is to the upper right of the waning crescent moon in the southeastern sky at 6:00 a.m. At this same time, Venus is half a fist above the eastern horizon.

Wednesday: Look up in the sky. It’s a bird. It’s a plane. It’s a dolphin. A dolphin? The constellation Delphinus the dolphin is nearly six fists above due south at 8:00 p.m. The constellation’s two brightest stars are called Sualocin and Rotanev, which is Nicolaus Venator spelled backwards. Venator worked at the Palermo Observatory in Italy in the mid nineteenth century. He slipped these names into Giuseppe Piazzi’s star catalog without him noticing. Sort of like when you would sneak cookies into your parent’s shopping cart, hoping they would not notice.

Thursday: Comet Lemmon (C/2025 A6) may be one of the brightest comets of the year. At 6:00 a.m., it is near the star Cor Caroli, about two and a half fists above the northeastern horizon. First, find the star at the bottom of the Big Dipper handle. Cor Caroli is about one fist to the right of that star. Comet Lemmon will be a little above Cor Caroli. Comet Lemmon will be closest to Earth on October 21. Read more about it at https://earthsky.org/space/comet-lemmon-best-comet-of-2025-finder-maps/.

Friday: Rho Cassiopeiae is the most distant star that can be seen with the naked eye by most people. It is about 8,200 light years away. That means that the light that reaches your eyes from that star left over 8,000 years ago, before the beginning of time according to the Byzantine calendar. Rho Cassiopeiae is nearly straight overhead at 11:00 p.m., just above the zigzag line that marks the constellation Cassiopeia.

The Ellensburg, WA sky for the week of October 4, 2025

Saturday: Tonight is International Observe the Moon night. Hopefully, you can go outside and look up between 6:00 p.m. and 5:00 a.m. If not, there are many virtual activities. For more information, go to https://moon.nasa.gov/observe-the-moon-night/

Sunday: At 8:00 p.m., the moon and Saturn are two fists held upright and at arm’s length above the east-southeastern horizon. Saturn remains below the moon throughout the night.

Monday: Tonight’s full moon is the Harvest Moon. The Harvest Moon is the full moon closest to the autumnal equinox. Usually that occurs in September. Approximately every three years, it occurs in October, replacing the Hunter’s Moon.

Tuesday: The Draconid meteor shower peaks for the next three nights with tomorrow night being the best. The meteors appear to come from a point in the head of Draco, the dragon constellation. This point is nearly straight overhead at 7:00 p.m. tonight. This point remains near the trapezoid-shaped head of Draco throughout the night. Unlike most meteor showers, this one is best observed in the early evening rather than after midnight. Call this the “early to bed” meteor shower. Draconid meteors are slow moving which means you will have an easy time differentiating true Draconid meteors, from Comet 21P/Giacobini-Zinner, from the stray grains of dust that happen to enter the Earth’s atmosphere every day and night. Unfortunately, the moon is full, meaning most of the dimmer meteors will be obscured. For everything you need to know about the Draconid meteor shower, go to https://earthsky.org/astronomy-essentials/everything-you-need-to-know-draconid-meteor-shower

Wednesday: Mars is just above the west-southwestern horizon at 7:00 p.m.

Thursday: In 2020, astronomers announced that they detected phosphine, a possible biosignature of life, in the upper atmosphere of Venus. Although the surface of Venus is inhospitable, astronomers have long speculated that the upper atmosphere could harbor life. Not Cloud City life from The Empire Strikes Back but maybe microbial life. In 2022, astronomers concluded that the original scientists found the signature of sulfur dioxide, not life. In 2023, the private company Rocket Lab published details about the first privately funded mission to another planet - their trip to Venus. The launch has been delayed until at least 2026. This Venus storyline is an excellent example of science at work. In less than two years, science went from “we may have found a marker for life on Venus” to “it is unclear if we found a marker for life” to “we probably didn’t find a marker for life” to “let’s visit Venus to closely study the thing we thought was a marker for life”. Do an internet search of the words Venus and phosphine and read the articles to follow the story. To get yourself in the mood, go outside at 6:15 a.m. Venus is a fist above the eastern horizon at this time. Read more about the potential mission at https://www.space.com/the-universe/venus/the-1st-private-mission-to-venus-comes-together-ahead-of-possible-2026-launch-photos

Friday: The Milky Way makes a faint white trail from due northeast, by the moon, through straight overhead to due southwest at 9:00 p.m. Starting in the northeast, the Milky Way “passes through” the prominent constellations Auriga the charioteer, Cassiopeia the queen, and Cygnus the swan with its brightest star, Deneb, nearly straight overhead. After Cygnus, you’ll see Aquila the eagle with its brightest star Altair about four and a half fists above the southwest horizon.

Saturday: Mars is right above the west-southwestern horizon at 7:30 p.m. Antares, which means “rival of Mars", is less than a half a fist to the right of the moon, low in the south-southwestern sky.

Sunday: You learned about Cassiopeia last week. Over 200 years ago, the astronomer Caroline Herschel discovered an open star cluster that looks like a rose. This cluster, called Caroline’s Rose, is about 6,500 light years away and consists of about 1,000 stars that are one third the age of the Sun. Through binoculars, it looks like a fuzzy patch. At 10:00 p.m., find the star at the top of the sideways “W” known as Cassiopeia. It is six fists held upright and at arm’s length above due northeast. When that star is in the lower left portion of your field of view, Caroline’s Rose is in the center to upper right. For more information about Caroline’s Rose, go to https://stardate.org/radio/program/2020-09-09.

Monday: Saturn is three fists above due southeast at 10:00 p.m.

Tuesday: Since Halloween is a month away, the stores are filled with bags of candy clusters. Use this reminder to take time to look at a star cluster. The Hyades cluster is an open star cluster that represents the V-shaped face of Taurus the bull. It is one of the biggest and nearest star clusters with about 200 stars 150 light years away. The Hyades cluster was the first cluster to be the subject of detailed motion studies. These studies allowed astronomers to pinpoint the distance to the Hyades and provide important information about the scale of the universe. Aldebaran, about one fist above the east-northeastern horizon at 11:00 p.m., is a foreground star and not a part of the Hyades cluster.

Wednesday: Need a caffeine pick-me-up? Make it a double. Need an astronomy pick-me-up? Make it a double double. Find the bright bluish star Vega, in the constellation Lyra the lyre, five and a half fists above due west at 10:00 p.m. Less than half a fist above Vega is the “star” Epsilon Lyra. If you look at Epsilon Lyra through binoculars, it looks like two stars. If you look at Epsilon Lyra through a large enough telescope, you will notice that each star in the pair is itself a pair of stars. Each star in the double is double. Hence, Epsilon Lyra is known as the double double. The stars in each pair orbit a point approximately in the center of each respective pair. The pairs themselves orbit a point between the two pairs.

Thursday: At 6:00 a.m., Venus is one fist above due east and Jupiter is five and a half fists above the southeastern horizon.

Friday: In 1987, the rock group Def Leppard sang “Pour some sugar on me, in the name of love. Pour some sugar on me, come on, fire me up”. In 2012, some European astronomers “found some sugar near stars, they were very young. Found some sugar near stars, out where planets formed.” Astronomers observed molecules of glycolaldehyde, a simple form of sugar, in the disk of gas and dust orbiting young binary stars. This is the first time astronomers have found this simple sugar so close to a star indicating that organic molecules can be found in planet-forming regions of stars.

The Ellensburg, WA sky for the week of September 20, 2025

Saturday: Saturn is in opposition tonight. That doesn’t mean that Saturn is stubborn. Opposition means that Saturn is on the opposite side of the Earth as the Sun. When an object is in opposition, it is at its highest point in the sky during the darkest time of the day. Thus, opposition is typically the best time to observe a planet. Saturn is about three and a half fists held upright and at arm’s length above due south at 1:00 a.m. It is nearly two fists above due southeast at 10:00 p.m. Careful readers of this column may recall that Saturn is in opposition about 12 days later each year: July 21, 2020, August 1, 2021, August 14, 2022, August 26, 2023, and September 7, 2024. An outer planet is in opposition when Earth passes it up as both orbit the Sun. The farther out a planet is, the less it has moved along its orbit, and the closer it is to exactly one year from one Earth passing to the next. For comparison, it is about 18 months between successive oppositions for Mars. Saturn is three fists above due southeast at 10:30 p.m. tonight.

Sunday: Tonight’s moon phase is new. Typically, that is pretty boring. Tonight, in the South Pacific and New Zealand it will be pretty exciting because there will be a partial solar eclipse visible from there. For more information so share with your New Zealand friends, go to https://www.timeanddate.com/eclipse/solar/2025-september-21

Monday: At 10:30 a.m. PDT, the center of the Sun crosses the celestial equator and passes into the southern sky. The celestial equator is an imaginary line that divides the sky into a northern and southern half. When the Sun is in the southern half of the sky, it appears to take a shorter path from rising to setting. It also does not get as high in the sky at noon. This leads to shorter days and longer nights. Since the Sun crosses the celestial equator today, there is an instant when it is equally in the northern and southern sky, called the north and south celestial hemispheres. This so-called “equal night” is given by the Latin word equinox. Thus, today is known as the Autumnal Equinox. However, the day and night are not of equal duration today. The sun rises at 6:49 a.m. and sets at 6:58 p.m. in the northern latitudes of the United States.

Tuesday: Mars is right above the west-southwestern horizon at 7:30 p.m.

Wednesday: To the people of Ancient Greece, the stars that are about five and a half fists above the northeastern and eastern horizons, respectively, at 10:30 p.m. were known as Cassiopeia and Andromeda, a mythological queen and her daughter. But not all cultures imagined the same pictures in the sky. To the people of Polynesia, the stars of Cassiopeia and Andromeda represented a dolphin, called Kwu. Cassiopeia formed its tail, the brightest stars of Andromeda formed its fins, and its fainter stars outlined the dolphin’s body.

Thursday: Ask someone which day in September has the same duration day and night. Go ahead, ask someone. Why are you still reading this? I can wait. If that person says the first day of autumn, they are wrong. Today, three days after the first day of autumn, is the date on which day and night are closest in duration. There are two main reasons for this. First, the atmosphere acts like a lens, bending light from the Sun above the horizon when the Sun is actually below the horizon. This makes the Sun appear to rise before it actually rises and appear to set after it actually sets. Second, fall starts when the center of the Sun passes through the point called the autumnal equinox. But the Sun is not a point. The upper edge of the Sun rises about a minute before the center of the Sun and the lower edge sets a minute after the center of the Sun. Thus, even if we didn’t have an atmosphere that bends the sunlight, daytime on the first day of autumn would still be longer than 12 hours.

Friday: At 6:00 a.m., Venus is a little more than a fist above due east. At this time, Jupiter is five fists above the southeastern horizon.

The Ellensburg, WA sky for the week of September 13, 2025

Saturday: Mars and Spica are just above the west-southwestern horizon at 8:00 p.m.

Sunday: While many people think they need a telescope to enjoy looking at the night sky, some objects actually look better through binoculars. Open star clusters are one of those types of objects. M39, the 39th object in Charles Messier’s catalog, is straight overhead at 11:00 p.m. This open star cluster contains about 30 stars in a region about seven light years across and a thousand light years away. A quick trigonometry calculation shows that the cluster is about the same size as the full moon in the night sky. Read more about M39 at https://stardate.org/radio/program/2022-09-04.

Monday: Saturn is one and a half fists above the east-southeastern horizon at 9:00 p.m.

Tuesday: “There’s water in them thar craters,” frozen water, which is. There has been speculation since the 1960s and indirect evidence since the 2000s of water on the Moon. Three years ago, astronomers studied data from four earlier missions. They noticed that the light reflecting off the bottom of craters near the lunar South Pole showed characteristics of light reflecting off pure ice. The water likely came from comet impacts or other solar system objects with trace amounts of water ice. Last summer, the Indian Space Research Organization became the fourth country to successfully land on the moon when Chandrayaan-3 landed near the lunar South Pole to study the water there. Read more about it at https://www.space.com/chandrayaan-3-moon-south-pole-why-nasa-wants-to-go-too. The moon is five fists above the eastern horizon at 6:00 a.m. Jupiter is less than a half fist to the lower right of the moon.

This will be a good day to try to see a planet during the day. Wait until the sun rises. Next, find the moon with your naked eye. Then aim your binoculars at the moon. Look for Jupiter below the moon. Finally, move away the binoculars and look at that same spot with your naked eye.

Wednesday: Fomalhaut, the farthest south of all the bright stars visible in the northern United States, is one fist above the south-southeastern horizon at 10:30 p.m.

Thursday:  Mnemonics are helpful for remembering astronomy facts. (Similarly, “Johnny Mnemonic,” the 1995 cyberpunk film, was helpful in getting Keanu Reeves’ career going.) After all, school children around the world are learning the order of the planets by remembering, “My very excellent mother just served us nine….” Oops, I guess that one needs updating with Pluto being classified as a dwarf planet. Well, here’s one that will not need updating for tens of thousands of years: the order of the stars in the Big Dipper. Because the nighttime stars are so far away from us, their actual motion through the sky, called their “proper motion” is not noticeable over even thousands of years. That is why the constellations have remained the same since ancient times. But two stars in the Big Dipper have a proper motion large enough such that in 100,000 years; the stars will no longer make a dipper shape. You can see this simulation at the American Museum of Natural History video found at https://youtu.be/sBfUBtdo8yo. Until then, you can remember the names of the seven dipper stars in order from handle to cup by remembering this helpful advice for teens: “AM, ask mom. PM, dad.” The stars are Alkaid, Mizar, Alioth, Megrez, Phad, Merek, and Duhbe. The Big Dipper is one fist above the northern horizon at midnight.

Friday: The moon, Venus, and the star Regulus form a tight cluster one and a half fists above due east at 6:00 a.m. Venus is about 100 times the brightness of Regulus. Both are to the upper right of the moon.

Today is an even better day to see a planet during the day. Wait until the sun rises. Next, find the moon with your naked eye. Then aim your binoculars at the moon. Look for Venus above the moon. Finally, move away the binoculars and look at that same spot with your naked eye.

The Ellensburg, WA sky for the week of September 6, 2025

Saturday: “You know Aries and Cancer and Draco and Libra. Leo and Pisces and Virgo and Hydra. But do you recall, the pointiest asterism of all? Triangulum, the three-sided asterism, had a very pointy shape. And if you didn’t know it, you could say it poked an ape.” Sorry. Some stores have started sending out their Christmas catalogs and that has put me in the mood to modify some Christmas songs. Anyway, Triangulum is a small constellation between the more prominent Andromeda and Aries. Its main feature is a skinny triangle oriented parallel to the ground and two and a half fists held upright and at arm’s length above the east-northeastern horizon at 10:00 p.m.

Sunday: The September full moon goes by many names. The Western Abenaki call it the Corn Maker Moon because of the impending harvest. The Tlingit call it the Child Moon because this is the time of year many animals wean their young. The Ojibwe call it the Falling Leaves Moon because the trees are starting to lose their leaves. This month, everyone in the Eastern Hemisphere will call it the Red Moon because there will be a total lunar eclipse visible throughout that hemisphere. During a total lunar eclipse, the Earth’s atmosphere acts like a prism and spreads the Sun’s white light into its component colors, with the red light hitting the moon. If you have friends in the Eastern Hemisphere, send them the link https://www.timeanddate.com/eclipse/lunar/2025-september-7 for more information.

Monday: Fomalhaut, the southernmost bright star visible from the northern USA, is one fist above the south-southeastern horizon at 11:00 p.m. In 2008, Fomalhaut and its surroundings became the first star system with an extrasolar planet to be directly imaged. See the family photo at https://apod.nasa.gov/apod/ap081114.html.

Tuesday: Saturn is one fist above the east-southeastern horizon at 9:00 p.m.

Wednesday: Mars and the bright star Spica are less than a half a fist above the west-southwestern horizon at 8:00 pm. Reddish mars is to the upper right of the brighter Spica.

Thursday: Earlier this week, you read about Fomalhaut, the second brightest star with a planet. The brightest star known to have a planet is Pollux, in the constellation Gemini. (First vs. second brightest is meaningless here because they are nearly identical in magnitude, 1.15 vs. 1.16.) Pollux is four and a half fists above due east at 5:30 a.m., right below its “twin” star Castor. Read more about Pollux at https://skyandtelescope.org/astronomy-news/meet-pollux-red-giant-exoplanet/.

Friday: Venus is two fists above due east at 6:00 a.m. Jupiter is four and a half fists above the east-southeastern horizon, to the lower right of Pollux and Castor.

The Ellensburg, WA sky for the week of August 30, 2025

Saturday: “Excuse me, do you have the time?” 

“No, but the Big Dipper does.”

You can use the orientation of the Big Dipper to tell time with a precision of about 15-30 minutes. First, find the two stars at the far end of the Big Dipper cup, the stars that do not touch the handle. Draw an imaginary line segment starting at the North Star and passing through the two Big Dipper cup stars. Now, draw a big circle around the North Star. Your circle is a 24-hour clock. Number the circle from 0 hours at the top, counterclockwise to 12 hours at the bottom of the circle, and back up to 24 hours at the top. (O hours and 24 hours are the same on this clock because the day is 24 hours long.) The hour number on the big circle closest to where your imaginary line intersects this circle is called your raw time. Due to the location of the Big Dipper compared to the rest of the stars, the time nearest the intersection (the raw time) is correct for March 6. For any other night, subtract two times the number of months the current date is after March 6 from the raw time. For example, let’s say the imaginary line between the North Star and the Dipper stars is pointed to the right. That means the raw time is 18 hours or 6 p.m. If you made this observation tonight, which is six months after March 6, you would subtract two times six or 12 hours from the raw time. Don’t forget to convert for daylight savings time if needed. If you prefer a more visual tool, and a fun project to do with your kids, there is a simple “star clock” template and instructions at https://skyandtelescope.org/observing/make-a-star-clock/. Use this paper star clock whenever your watch is broken. The Big Dipper is in the northwestern sky at 9:00 p.m. tonight.

Sunday: Mars is about a half a fist above the western horizon at 8:30 p.m. Saturn is rising in the east at this time. By 9:30 p.m., Saturn is one fist above the eastern horizon.

Monday: Labor Day was the brainchild of labor unions and is dedicated to American workers. The first Labor Day was celebrated in 1882. The Greek mythical hero Hercules probably wished there was a Labor Day to commemorate his work. As punishment for killing his family while he was temporarily insane, he had to perform twelve nearly impossible tasks such as killing monsters or stealing things from deities. Hmmm. Maybe we shouldn’t commemorate his labors. But we can enjoy his constellation. The keystone asterism representing the body of Hercules is six fists above the western horizon at 10:00 p.m. For more information about the Labors of Hercules, go to http://goo.gl/ozVF5.

Tuesday: Had the script been written a little differently for a well-known Robin Williams movie, we might have heard Mr. Williams shout, “Goooood Morning Orion the hunter.” Orion is typically thought of as a winter constellation. But it makes its first appearance in the early morning summer sky. The lowest corner of Orion’s body, represented by the star Saiph (pronounced “safe”), rises at 2:45 a.m. By 5:30 a.m., Orion’s belt is three fists above the southeastern horizon.

Wednesday: School starts this week, so it is time for a little geometry review. A square is a regular quadrilateral. This means it has four equal sides, four equal angles, and wears old fashioned clothing. Go outside at 9:30 p.m. tonight with a notebook in hand to sketch one. The Great Square of Pegasus is balancing on its corner about two fists above the eastern horizon. The top corner of the square is two fists above the bottom corner. The other two corners are to the left and right of the line segment connecting the top and bottom corners.

Thursday: Jupiter, Venus, and Mercury make a line in the early morning sky. At 5:45 a.m., Jupiter is four fists above the eastern horizon. Venus, the brightest of the three, is two fists above the eastern horizon. Mercury is right above the east-northeastern horizon.

Friday: Geometry review, part 2. Go outside at 9:30 p.m. tonight with a notebook in hand. (Good teaching involves a little repetition.) A triangle is a polygon with three corners and three line segments as sides. A good example is the Summer Triangle made up of the bright stars Vega, Deneb, and Altair. Altair is five fists above the southern horizon. Vega, the brightest star in the triangle, is seven and a half fists above the southwestern horizon. Deneb is a little bit east of straight overhead.

The Ellensburg, WA sky for the week of August 23, 2025

Saturday: The moon is almost directly between the Earth and the Sun today. That means you won’t be able to see it. But that does not mean it doesn’t exist. Contrary to the belief of toddlers and immature politicians, just because you can’t see something doesn’t mean it doesn’t exist. (Note a double negative statement followed by a triple negative statement. I’m not unsorry about that.) Now, back to the science. What would happen to the Earth if the moon really didn’t exist? In that 2013 blockbuster Oblivion, aliens destroy the moon and Tom Cruise survives. In real life, the long-term effects on the Earth would be devastating to life as we know it. The moon stabilizes the spin axis of the Earth keeping the seasons fairly uniform over time. For more information on what would happen to the earth if the moon were destroyed, go to https://www.popsci.com/what-would-happen-if-moon-suddenly-disappeared/. For more information on Thomas Cruise Mapother IV, go to http://en.wikipedia.org/wiki/Tom_Cruise.

Sunday: School starts soon. One of the most important lessons to learn in science class is to always save your data. Even if the data looks “wrong” or you don’t think it contains essential information, you never know what future researchers might find in it. Two years ago, Kepler space telescope scientists reanalyzed older data and discovered an Earth-sized planet orbiting in the habitable zone of its host star. It turns out the previous computer algorithm misidentified it. Maybe there are other Earth-cousins hiding in the data somewhere. Read more about it at https://www.nasa.gov/press-release/earth-size-habitable-zone-planet-found-hidden-in-early-nasa-kepler-data.

Monday: Mars is a half a fist above the western horizon at 8:45 p.m. Soon it will be lost in the glare of the Sun’s light.

Tuesday: “The sky is black (or light polluted), the stars are white (or red or orange or yellow or blue), the whole world gazes upon the sight (except where there are too many city lights or people are lazy.” Wow. It is difficult to write a flowing set of lyrics when there are so many parenthetical thoughts. Most people think of the sky’s blackness as a lack of stars. But dark patches in the Milky Way are actually massive clouds of dust that are blocking the stars behind them. Two of the most prominent are dark nebulae B142 and B143 in the constellation Aquila the eagle. These are easy to find and enjoy with binoculars. First find the bright white star Altair, five fists above due south at 10:30 p.m. Then move your binoculars up and to the right a little bit to the next bright star Tarazed, about one fifth as bright. B142 and B143 are to the upper right of Tarazed. They make an “E” shape in the sky; fitting because American astronomer E. E. Barnard first proposed that these were dust clouds and not simply big spaces between the stars. For more information about dark nebulae, including many more to look at with binoculars, go to https://goo.gl/9tiqdh.

Wednesday: Saturn is two fists above the east-southeastern horizon at 11:00 p.m.

Thursday: The star FG Sagittae, in the constellation Sagitta the arrow, is changing before our eyes. Over the past 60 years, FG Sagittae has turned from blue to white to orange, indicating that it has puffed up and gotten cooler. The star is too dim to be seen with the naked eye, but the constellation looks like a small, horizontal arrow six fists above due south at 10:30 p.m.

Friday: Jupiter, Venus, and Mercury make a line in the early morning sky. At 5:15 a.m., Jupiter is three fists above due east. Venus, the brightest of the three, is one and a half fists to the lower left of Jupiter. Mercury is right above the east-northeastern horizon.

The Ellensburg, WA sky for the week of August 16, 2025

Saturday: Not every woman in the Black family is evil. Let’s focus on the good. Andromeda Black, Bellatrix’s sister, is a good witch and the mother of Tonks, a young witch from the last few Harry Potter books. (If these Harry Potter references are confusing, you better start reading the books.) Andromeda the constellation is an interesting one. It contains the Andromeda galaxy, the most distant object visible with the naked eye from a dark site. To locate the Andromeda Galaxy, first find the Great Square of Pegasus. At midnight, the left-hand corner of the square is four fists held upright and at arm’s length above the eastern horizon. Less than two fists to the left and down a little bit is another star, the same brightness as the star at the corner of the square. From that star, hop about a half a fist up to a star that is about one fourth as bright. Less than another half fist in the same direction is a fuzzy oval patch of light known as the Andromeda Galaxy. The galaxy is impressive to see in binoculars. It consists of about one trillion stars and is 2.5 million light years away.

Sunday: Arcturus is two and a half fists above due west at 10:15 p.m. This star, whose name means bear watcher, is the brightest in the sky’s northern hemisphere. It follows Ursa Major, the Great Bear, around the North Star. Arcturus is the closest giant star to Earth. It is one of the few stars whose diameter can be measured directly rather than being inferred from its density and mass, which themselves are derived from other parameters.

Monday: Mars is a half a fist above the western horizon at 9:00 p.m. An hour later, at 10:00 p.m., you can find Saturn a half a fist above the eastern horizon.

Tuesday: Mercury will be as far away from the Sun in the sky as it will get this orbital cycle. This "farthest away" point is known as the planet's greatest elongation. Since Mercury is in the morning sky, it is west of the Sun and this occurrence is called the greatest western elongation. This morning, Mercury is half a fist above the east-northeastern horizon at 5:15 a.m. Over the next few weeks, Mercury will move toward the Sun in the sky. By mid-October, it will be visible in the evening sky.

Wednesday: The moon, Venus, and Jupiter make a small right triangle low in the eastern sky at 5:30 a.m. Venus is to the lower right and Jupiter is to the upper right of the moon. As a bonus, the bright stars Pollux and Castor in the constellation Gemini are to the upper left of the moon.

Thursday: All stars rotate. Our Sun takes a little less than one Earth month to rotate once on its axis. Astronomers studied the relationship between mass, stellar rotation, and planetary formation by aiming NASA’s recently retired Kepler space telescope toward the Pleiades open star cluster. All 1,000 stars in this group are nearly the same age, 125 million years old. Since all the stars are the same age and formed from the same set of materials, astronomers have the ideal “laboratory” to isolate the role star mass plays on star rotation and evolution. Read more about the findings at https://www.jpl.nasa.gov/news/kepler-watches-stellar-dancers-in-the-pleiades-cluster. See the Pleiades for yourself, about a half a fist above the east-northeastern horizon at 11:30 p.m.

Friday: Seventeenth century astronomers documented the appearance of a new star, or “nova,” in 1670. However, as modern astronomers studied the records of the star, called Nova Vulpeculae 1670, they realized it didn’t have the characteristics of a typical nova because it didn’t repeatedly brighten and dim. It brightened twice and disappeared for good. Turning their telescopes to the region, they discovered the chemical signature to be characteristic of a very rare collision of two stars. For more information about this discovery, go to http://goo.gl/rJnC2G. Nova Vulpeculae 1670 is right below the binary star system Alberio, the head of Cygnus the swan. Alberio is seven fists above due south at 10:30 p.m.

The Ellensburg, WA sky for the week of August 9, 2025

Saturday: One minor Harry Potter character actually has two well-known star names: Regulus Arcturus Black, the brother of Sirius Black who is Harry Potter’s godfather. Regulus Black was a former follower of Voldemort, the bad guy of the Harry Potter series. However, Regulus tried to dissociate himself from Voldemort and was killed. In the sixth book, Harry found an important note written by someone known only by the initials R.A.B. Hmmm. R.A.B. Regulus Arcturus Black perhaps? Regulus the star is right in line with the Sun at this time of year so it is not visible. Arcturus, the second brightest star visible in the nighttime sky in Washington and at Hogwarts, is about two and a half fists held upright and at arm’s length above the western horizon at 11:00 p.m.

Sunday: Venus and Jupiter are right next to each other, low in the eastern sky for the next few mornings. At 5:00 a.m., they are two fists above the eastern horizon. Venus is brighter and to the upper right of Jupiter. Over the next few weeks, Venus will move to the lower left, down toward the east-northeastern horizon, and eastward compared to the background stars.

Monday: The Perseid meteor shower peaks this morning and tomorrow morning. In case you decide to stay in bed this week, the shower is active until about September 1 so you may still enjoy an increased number of meteors later. The moon is in the waning gibbous phase so its light will obscure all but the brightest meteors. The meteors appear to come from a point just below the W of the constellation Cassiopeia. This point is about three fists above the northeast horizon at 11:00 p.m. By dawn, this point is nearly straight overhead. For tips about optimizing your viewing this year, go to https://earthsky.org/?p=165416. As your Mother might say, dress warm and sit in a comfortable chair for maximum enjoyment. These meteors are sand to pea-sized bits of rock that fell from Comet Swift-Tuttle. They travel about 40 miles per second as they collide with the Earth and burn up in the atmosphere.

Tuesday: Bellatrix Lestrange is Sirius Black’s cousin. But certainly not kissing cousins. They are killing cousins. Bellatrix kills Sirius in a fight at the Ministry of Magic. Bellatrix the star is the third brightest star in the constellation Orion the hunter. It is two and a half fists above the east-southeastern horizon at 5:00 a.m.

Wednesday: Of course, Bellatrix is in cahoots with “he who must not be named.” Now, that’s a poorly written sentence, using an obscure synonym for “conspiring” and a vague reference to someone. I must be under the curse “writicus dreadfulium.” Clearly this is the work of Tom Riddle, whose mother is named Merope Gaunt. Merope is a star in the Pleiades, an open star cluster about five and a half fists above the southeastern horizon at 5:15 a.m. Mercury is a half a fist above the east-northeastern horizon at this time.

Thursday: Draco Malfoy, Harry Potter’s young nemesis, is related to Sirius Black. Draco’s mother, Narcissa Black (Sirius’ cousin), helped develop a plan to trap Harry at the Ministry of Magic in the fifth book. Draco’s namesake, the constellation Draco the dragon, is one of the largest constellations in the sky, winding around the North Star. Draco’s head is a four-sided figure a little on the northwest side of straight overhead at 10:00 p.m.

Friday: Antares, the brightest star in the constellation Scorpius, is one and a half fists above the south-southwestern horizon at 9:00 p.m. Draco Malfoy was so impressed with this constellation name that he used it for the first name of his son. Mars is half a fist above the western horizon at this time.

The Ellensburg, WA sky for the week of August 2, 2025

 Saturday: Star light. Star bright. The first star you see tonight might be Vega, nearly seven fists held upright and at arm’s length above the eastern horizon right after sunset. 

Sunday: Mars is half a fist above the western horizon at 9:30 p.m. In case that is not interesting enough for you, look to the south. The bright star Antares, which means rival of Mars, is right above the moon.

Monday: It is often said that Earth is a water world because about 70% of the Earth’s surface is covered by water. What would it look like if all that water on the surface were gathered up into a ball? That “ball” would be about 700 km in diameter, less than half the diameter of the Moon. The Astronomy Picture of the day shows us right here https://apod.nasa.gov/apod/ap120515.html.

Tuesday: Venus, the brightest point of light in the sky, is two fists above the eastern horizon at 5:00 a.m. Jupiter is about a half a fist to the lower left of Venus.

Wednesday: The Gemini twins, first Castor and then Pollux, rise just before the Sun. At 5:00 a.m., Pollux is one and a half fists above the northeastern horizon. A slightly dimmer Castor is half a fist above it. Pollux is the brightest star, as observed from Earth, known to have a planet orbiting it. The planet, creatively called Pollux b, has about twice the mass of Jupiter.

Thursday: If you want to show your loved ones a celestial sign that they should hang up their clothes, show them Brocchi's Cluster, commonly known as the Coat Hanger cluster because of its resemblance to an upside-down coat hanger. The cluster is about six fists above due south at 11:20 p.m., midway between Altair and Vega, the two brightest stars in the Summer Triangle. You'll need binoculars to make out the shape. First find Altair five fists above the southern horizon. Slowly move your binoculars up toward Vega. You will run into the coat hanger along the way. And while you are at it, put away your shoes.

Friday: Tonight’s August full moon is traditionally called the full sturgeon moon by Midwest and northeastern Native American tribes because the sturgeon in lakes in this part of the country were easiest to catch during this full moon time. The Ojibwe in the Midwest harvest wild rice in August, calling the August full moon the Ricing Moon.
