The Ellensburg, WA sky for the week of January 10, 2026

Saturday: How do you study the life cycle of a dog? Easy. Get a dog from the animal shelter, care for it for 15 years and study it. How do you study the life cycle of a star? Easy. Pick a star, watch it for a few billion years, and…. Wait a minute. Astronomers can’t observe something for a few billion years. Instead, they study stars that are at different points in their long-life cycle and piece together the information from those different stars. What they do is like studying a one-year-old dog for a few minutes, then studying a different two-year-old dog for a few minutes, and so on. The sky in and near the constellation Orion provides an example of four objects at different points of star life.

First, find Rigel, the bright star in the lower right corner of the constellation Orion. This star, rapidly burning its fuel for a high energy but short-lived existence, is three and a half fists held upright and at arm’s length above due south at 10:00 p.m. It was not, is not, and never will be like our Sun. However, about one fist up and to the left are the three objects of Orion’s sword holder. The middle “star” is really a star-forming region called the Orion nebula. There you’ll find baby Suns. Now, look about two fists to the right and one fist down from Rigel. You should be looking at a star that is about one tenth as bright as Rigel but still the brightest in its local region. The third star to the right of that star is Epsilon Eridani, the most Sun-like close and bright star. Betelgeuse, in the upper left corner of Orion, is a star at the end of its life that started out life larger than the Sun.

Sunday: Jupiter is in opposition tonight. That doesn’t mean Jupiter is fighting against an authoritarian leader. Opposition in this case means that Jupiter 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. Jupiter is six and a half fists above due south at midnight. If you don’t want to stay up so late, you can see it three and a half fists above the eastern horizon at 8:00 p.m.

Monday: Most constellations don’t look like the object their name refers to. That’s because most constellations don’t have such a simple object to emulate as Triangulum does. Triangulum is shaped like a… wait for it…. wait for it…. A thin isosceles triangle. Metallah is the only mononymous star in the constellation. In Latin, this star is called Caput Trianguli, the head of the triangle. Triangulum is four and a half fists above due west at 10:00 p.m. The triangle is pointing straight down with Metallah at the bottom. The Triangulum Galaxy can be seen with binoculars about half a fist to the lower right of Metallah. This is the galaxy that the USS Enterprise travels to after the warp drive engine malfunctions in The Next Generation episode called “Where No One Has Gone Before”.

Tuesday: Saturn is three fists above the southwestern horizon at 7:00 p.m.

Wednesday: Antares is less than a half a fist to the left of the moon, one fist above the south-southeastern horizon at 7:00 a.m.

Thursday: Have you ever looked down on the ground and spotted a penny? In Yakima? While you were standing in Ellensburg? If you have, then you may be able to see the star Hamal as more than just a point of light. It has an angular diameter that can be directly measured from Earth. Hamal, the brightest star in the constellation Aries the ram, has the same angular diameter as a penny 37 miles away. (For comparison, the moon is about half the diameter of a penny held at arm’s length.) Hamal is three fists above due west at 11:00 p.m. Hamal is just to the left of Triangulum and is the brightest star in that region of the sky.

Friday: You never see a giraffe on the ground in Ellensburg. But you can look for one every night in the sky. The constellation Camelopardalis the giraffe is circumpolar from Ellensburg’s latitude of 47 degrees north meaning it is always above the horizon. Don’t expect to be overwhelmed by the appearance of the stars in Camelopardalis. The brightest star in the constellation appears only about half as bright as the dimmest star in the Big Dipper. However, the actual luminosities of the three brightest stars in Camelopardalis are very high, each at least 3,000 times more luminous than the Sun. Alpha Camelopardalis, a mind boggling 600,000 times more luminous than the Sun, is seven fists above due north at 9:00 p.m.

The Ellensburg, WA sky for the week of January 3, 2026

Saturday: If the Sun looks big today, your eyes are not playing tricks on you. The Earth is at perihelion at 9:00 this morning. If you dig out your Greek language textbook, you’ll see that peri- means “in close proximity” and helios means “Sun.” So, perihelion is when an object is closest to the Sun in its orbit, about 1.5 million miles closer than its average distance of 93 million miles. Since it is winter in the Northern Hemisphere now, the seasonal temperature changes must not be caused by the Earth getting farther from and closer to the Sun. Otherwise, we’d have summer when the Earth is closest to the Sun. The seasons are caused by the angle of the sunlight hitting the Earth. In the winter, sunlight hits the Earth at a very low angle, an angle far from perpendicular or straight up and down. This means that a given “bundle” of sunlight is spread out over a large area and does not warm the surface as much as the same bundle in the summer. For the Northern Hemisphere, that very low angle occurs in December, January, and February.

This evening and tomorrow morning’s weather forecast: showers. Meteor showers, that is. The Quadrantid meteor shower peaks this evening. Meteor showers are named after the constellation from which the meteors appear to originate. That makes this shower mysterious because there isn’t any constellation with this name now. The shower was named after Quadrans Muralis, an obsolete constellation found in some early 19^th century star atlases. These meteors appear to come from a point in the modern constellation Draco the dragon. This point is about three fists above the northeastern horizon at 1:00 a.m. This year, the brightness of the Full Moon obscures the dimmer meteors.

Meteors are tiny rocks that hit the Earth and burn up in the atmosphere. Most meteors are associated with the path of a comet. This shower consists of debris from an asteroid discovered in 2003. Keeping with the comet-origin paradigm, astronomers think the asteroid is actually an “extinct” comet, a comet that lost all its ice as it passed by the Sun during its many orbits. For more information about the Quadrantid meteor shower, go to http://earthsky.org/?p=155137.

Sunday: Has it been tough to wake up this past week? It should have been because the sunrise has been getting a little later since summer started. I know. I know. December 21 was the shortest day of the year. But, because the Earth’s orbit around the Sun is elliptical and not circular, the Earth does not travel at a constant speed. It moves faster when it is closer to the Sun and slower when it is farther away. This leads to the latest sunrise occurring in late December/early January and the earliest sunset occurring in early December. Neither of these happen on the first day of winter. On the first day of winter, however, the interval between sunrise and sunset is the shortest, making it the shortest day of the year. For more information, go to http://goo.gl/SJC5r.

Monday: At 7:30 p.m., Saturn is three fists above due southwest and Jupiter is two and a half fists above the eastern horizon.

Tuesday: Let’s review three important sets of three cats. There’s Josie, Valerie, and Melody of Josie and the Pussycats. Felix, Tom, and Sylvester from old time cartoons. And, if you want to get away from the mind-numbing effects of television, there’s Leo the lion, Leo Minor, and Lynx in the night sky. Leo is by far the most prominent of these three constellations. Its brightest star called Regulus is two fists above the eastern horizon at 10:00 p.m. The backwards question mark-shaped head of Leo is above Regulus and the trapezoid-shaped body is to the left of it. Leo Minor consists of a few dim stars right above Leo. Pretty wimpy. The long dim constellation called Lynx spans from just above Leo Minor to close to straight overhead. You and fellow stargazers won’t need to wear a long tail or ears to enjoy these stellar cats.

Wednesday: In 1984, American singer Rockwell released the song “Somebody’s Watching Me”, backed up by Michael Jackson. In 2020, NASA’s Spitzer Space Telescope released a picture of two bubbles of gas and dust that look like eyes watching you. Stare back at them by going to https://www.spitzer.caltech.edu/image/ssc2020-17a-something-out-there-is-watching-you.

Thursday: Now that you know meteors are rocks that burn up in the atmosphere, you will soon start to wonder what would happen if those 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.

Friday: Draco Malfoy makes an appearance in all seven books of the Harry Potter series. Perhaps you’ve heard of these. But the constellation Draco the dragon makes an appearance in the sky every night. It is a circumpolar constellation as viewed from Ellensburg meaning it never goes below the horizon. The head of the dragon is one fist above due north at 10:30 p.m. Eltanin, the brightest star in the constellation, is at the lower left-hand corner of the trapezoid-shaped head of Draco.

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.
