The Ellensburg, WA sky for the week of November 2, 2024

Saturday: 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, about five fists held upright and at arm’s length above the southeastern horizon at midnight. This is when the best meteor watching begins.

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 used 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: Antares is right above the young crescent moon. Both are just above due southwest at 5:00 p.m. The elusive planet Mercury is one fist to the right of the moon.

Monday: The Southern Taurid meteor shower peaks tonight. These are slow moving meteors that result in the occasional fireball. The Taurid meteor showers produce a few bright meteors every hour. The waxing crescent moon will set before midnight, leaving the sky dark for the meteors. 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: Venus is about a half a fist above the southwest horizon at 5:30 p.m., just to the right of the crescent moon.

Wednesday:  If you looked for Taurid meteors to the right of the Hyades, you may have wondered about the bright object to the left of the Hyades cluster. That is the planet Jupiter. You don’t have to stay up late to see it. It is two fists above the eastern horizon at 9:00 p.m. At this same time, Saturn is three fists above the south-southwestern horizon.

Thursday: Sirius, the brightest star in the nighttime sky, is a half a fist above the southeastern horizon at 11:30 p.m.

Friday: Is visiting Mars too unrealistic? How about America’s desert Southwest? Still not happening? Then just look at some photos from… from…. Hmmm. The photos at https://goo.gl/Elx7O8 look like they could be from either place. The Murray Buttes region of Mars, where the Curiosity rover has been exploring, looks a lot like the landscape of Utah. So much so that the Mars-based movie John Carter was filmed in the desert of southern Utah. Look for John Carter at your local video store. Listen to the soundtrack on your 8-track tape player. Then take a Polaroid selfie of you enjoying each experience. Mars is one and a half fists above the east-northeastern horizon at 11:00 p.m.

The Ellensburg, WA sky for the week of October 26, 2024

Saturday: Saturn is two and a half fists held upright and at arm’s length above due southeast at 7:00 p.m.

Sunday: 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.

Monday: Did you know that moons and dwarf planets can share 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 right of the open star cluster called the Pleiades. Move the Pleiades to the far left of your binoculars field of view. Uranus will be on the far right. Uranus is the object that will have moved over the course of a few nights.

Tuesday: Fomalhaut is one and a half fists above due south at 10:00 p.m.

Wednesday: Venus is a half a fist above due southwest at 6:45 p.m.

Thursday: Today is Halloween. If you need costume ideas, look low in the sky at 7:00 p.m. Arcturus is one fist 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 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. 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 featured in popular fiction, go to https://en.wikipedia.org/wiki/Stars_and_planetary_systems_in_fiction.

Friday: 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.

The Ellensburg, WA sky for the week of October 19, 2024

Saturday: 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 and tomorrow night. 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 is just past the full phase, meaning it will obscure the dimmer meteorites that pass through the Earth’s atmosphere in the pre-dawn sky. 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.

Sunday: 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.

Monday: Jupiter will be about a half a fist to the lower right of the moon throughout the night. They rise in the east-northeastern sky just before 9:00 p.m. By midnight, they are three fists above the eastern horizon.

Tuesday: Venus is about a half a fist above due southwest at 6:30 p.m.

Wednesday: Mars will be about a fist below the moon throughout the night. They are about one fist above the east-northeastern horizon at midnight.

Thursday: 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.

Friday: Halloween weekend is a great time to celebrate the dead. Dead stars, that is. Black holes are and neutron stars are the result of 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 relatively short period at the end of its life, the Sun will end up with a core of carbon and oxygen that no longer produces energy through nuclear fusion. Without the outward radiation pressure from fusion 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 a little more than two 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 12, 2024

 Saturday: Comet Tsuchinshan-ATLAS moved into the evening last week. It will be visible in the evening west-southwestern sky for the next two weeks. At 7:00 p.m., the comet will be about a half a fist above the western horizon. That will be difficult to see in the bright twilight sky. By the end of the week, it will be higher in the sky but dimmer. There is a map of where to find the comet right after sunset for the next two weeks at https://skyandtelescope.org/astronomy-news/get-ready-for-comet-tsuchinshan-atlas-the-best-is-yet-to-come/. The sky locations on the map are for 0 hours Universal time on the dates listed. That is about sunset Pacific Daylight Time the day before. So, the symbol labeled 14 corresponds to the sky location for about sunset on October 13.

Sunday: Jupiter is over one and a half fists above the eastern 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 at this time. Callisto, the most distant from Jupiter, is on one side of Jupiter, with Callisto being the farthest of all the moons. Europa and Io are on the other side, with Io being the closest of all the moons.

Monday: Saturn is less than a fist to the right of the moon throughout the night. They are three and a half fists above the southern horizon at 10:30 p.m.

Tuesday: 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 six fists above the northeastern horizon at 8:00 p.m., just above the zigzag line that marks the constellation Cassiopeia.

Wednesday: You’ve seen all the top 100 lists: top 100 ways to bench press, top 100 Uzbek 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 Moon is one fist above due east. 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.

Thursday: The constellation Vulpecula, the fox, stands six fists above due southwest at 9 p.m. It is in the middle of the Summer Triangle, which is defined by the bright stars Vega, Deneb, and Altair. The fox is so faint that you need dark skies to see it.

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 October 5, 2024

Saturday: Saturn is three and a half fists held upright and at arm’s length above due south at 11:00 p.m. Jupiter is a little more than one fist above the east-northeastern horizon at this time.

Sunday: 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 nearly 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/.

Monday: It is good to plan ahead while you have meteors on your mind 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 mornings of October 20 and 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 two fists above the southeastern horizon at 1:00 a.m. 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

Tuesday: “I’m a little teapot, short and stout. The galactic center, I pour it out.” (I’m a Little Teapot, astronomy version, 2023.) Despite its great size and importance, the center of our Milky Way galaxy and its giant black hole remains 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.

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: The Milky Way makes a faint white trail from due northeast 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.

Friday: Venus is a half a fist above the southwest horizon at 7:00 p.m.

The Ellensburg, WA sky for the week of September 28, 2024

Saturday: You learned about Cassiopeia last week. The astronomer Caroline Herschel discovered an open star cluster that looks like a rose over 200 years ago. 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.

Sunday: Saturn is two and a half fists above the southeastern horizon at 9:00 p.m.

Monday: 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.

Tuesday: Jupiter is one fist above the east-northeastern horizon at 11:00 p.m. By 1:00 a.m., Jupiter is three fists above due east and Mars is where Jupiter used to be, one fist above the east-northeastern horizon.

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, nearly six 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: Four years ago, 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. Last year, astronomers concluded that the original scientists found the signature of sulfur dioxide, not life. Last year, the private company Rocket Lab published details about the first privately funded mission to another planet - their trip to Venus. The trip was originally scheduled to launch this year but has been delayed to at least 2025. 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 7:15 p.m. Venus is a half fist above the west-southwestern horizon at this time. Read more about the potential mission at https://www.space.com/rocket-lab-private-venus-mission-delayed-2025.

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 21, 2024

Saturday: At 5:30 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 takes 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 6:48 a.m. and sets at 7:00 p.m. in the northern latitudes of the United States. At these latitudes, day and night are closest to equal duration on Tuesday.

Sunday: “There’s water in them thar craters,” frozen water, that 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 one fist above the north-northeast horizon at 11:00 p.m.

Monday: To the people of Ancient Greece, the stars that are about five and a half fists above the northeastern and eastern horizons, respectively, at 10:00 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.

Tuesday: 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 in 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.

Wednesday: Mars is less than a half a fist to the lower right of the last quarter moon at 6:00 a.m. Jupiter is to the upper right of the moon.

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: Saturn is exactly two and a half fists above due southeast at 9:00 p.m.
