The Ellensburg, WA sky for the week of April 25, 2026

Saturday: The bright star Regulus is about a thumb width to the upper right of the moon at 9:00 p.m. They are five and a half fists held upright and at arm’s length above due south.

Sunday: One hundred six years ago tonight, astronomers Heber Curtis and Harlow Shapley were debating the distances of some of our farthest neighbors: galaxies. Curtis argued that the universe consisted of many galaxies millions of light years away. Shapley thought that the spiral structures seen in telescopes were actually close by as a part of the Milky Way. They also had different views on the size of the Milky Way. Learn more about their debate, called the Great Debate, at https://youtu.be/0MJCqJPMpeY. Learn more about the Milky Way by watching the center of it rise over the southeastern horizon at about 1:00 a.m.

Monday: The Eta Aquarid meteor shower peaks just before dawn on May 5 and 6. Since this meteor shower has a fairly broad peak range, you should start looking before dawn every morning this week. Meteor showers are named after the constellation from which the meteors appear to originate. The meteors appear to come from a point in the constellation Aquarius near the star Eta. This point is about one fist above the east horizon at 4:00 a.m. The Eta Aquarid meteors slam into the Earth at about 40 miles per second. They often leave a long trail. The Eta Aquarid meteors are small rocks that have broken off Halley’s Comet. For more information about the Eta Aquarids, go to http://earthsky.org/?p=158833.

Tuesday: Celebrate the ending of Global Astronomy Month by reading some poems and short stories submitted by astronomy fans at https://my.astronomerswithoutborders.org/programs/astroarts/astropoetry.

Wednesday: At 9:30 p.m., Jupiter is four fists above the western horizon and Venus is one fist above the west-northwestern horizon.

Thursday: Some open star clusters are easy to find and see, such as The Pleiades and The Hyades clusters in the constellation Taurus the bull. Some are difficult to see. M35, an open star cluster in the constellation Gemini the Twins, is in the middle. It doesn’t jump out at you, but it is easy to find if you have help. M35 is about one and a half fists above the west-northwestern horizon at 9:30 p.m., just to the right of two reddish stars of similar brightness. It is a family of a few thousand stars about 3,000 light years away. Open star clusters are young for stars, this one being about 100 million years old. The cluster is best seen using binoculars or a small telescope.

Friday: Orion stands low in the southwestern sky. At 9:00 p.m., the middle of Orion’s belt is about one fist above the west-southwest horizon. And talk about belt tightening! Alnilam, the middle star in the belt, is losing mass at a rate of about 100 thousand trillion tons a day. That’s a 1 followed by 17 zeros tons per day.

Saturday: Venus is one fist held upright and at arm’s length above the west-northwestern horizon at 9:00 p.m., just to the left of a two-day-old moon.

Sunday: The small house-shaped head of Hydra is four fists above the southwestern horizon at 10:00 p.m.

Monday: Sirius, the brightest star in the night sky, is getting lower and lower as the days go by. It is one fist above the southwestern horizon at 9:00 p.m. By mid-May, it will be lost in the glare of the setting Sun.

Tuesday: The Lyrid meteor shower peaks tonight. The meteors appear to come from a point to the right of the bright bluish star Vega in the constellation Lyra the lyre. This point is about three fists above the east-northeast horizon at midnight tonight. The best time to observe this year is between midnight and dawn. Typically, this is one of the least interesting major meteor showers of the year, with 10-20 bright, fast meteors per hour. However, it is also one of the most unpredictable. As recently as in 1982, there were 90 meteors visible during a single hour. In addition, the Lyrid meteor shower has historical interest because it was one of the first ones observed. Chinese records say “stars fell like rain” in the shower of 687 B.C. As your mother might say, dress warmly and sit in a comfortable chair for maximum enjoyment. Meteors are tiny rocks that hit the Earth and burn up in the atmosphere. For more information, go to http://earthsky.org/?p=158735.

Wednesday: Jupiter is less than a half a fist below the moon at 9:00 p.m., about five fists above the west-southwestern horizon.

Thursday: Even though Zubenelgenubi is the second brightest star in Libra, its name means Southern Claw in Arabic, an artifact of the time that it was considered part of Scorpius the scorpion. Zubenelgenubi is a visual binary, consisting of a white and yellow star that are about 230 arc minutes apart from each other in the sky. This is about the same angular distance as the diameter of a medium sized dark spot on the Moon and can be easily resolved with binoculars. In actuality, the two stars are at least 5,500 astronomical units apart from each other, about 130 times the distance between the Sun and Pluto. Libra is one and a half fists above the southeastern horizon at midnight.

Friday: As the rock group Journey once thought of singing, “Wheel in the sky keeps on turnin’. I know where the Dipper’ll be tomorrow.” Every night, the Big Dipper and Cassiopeia make a wheel in the sky that turns around the North Star in a counterclockwise direction. Every year on April 24 at 10:00 p.m., the Big Dipper is straight overhead and W-shaped Cassiopeia is low on the northern horizon. Every year on April 25 at 10:00 p.m., the Big Dipper is straight overhead and W-shaped Cassiopeia is low on the northern horizon. Every year on April 26 at 10:00 p.m., the Big Dipper is straight overhead and W-shaped Cassiopeia is low on the northern horizon. Oh, am I boring you? Of course, there are subtle charges in the position from night to night. Each northern constellation moves about one degree counterclockwise from one night to the next. But this is not going to change their position in the sky drastically over a few days. So, if you know where the Big Dipper is tonight, you DO know where it’ll be tomorrow. If you are really struggling to understand this concept, Don’t Stop Believin’ in yourself. Just keep studying Faithfully.

The Ellensburg, WA sky for the week of April 11, 2026

Saturday: At 8:45 p.m., Venus is one fist held upright and at arm’s length above the western horizon.

Sunday: Do people think you have a magnetic personality? The star Cor Caroli understands how you feel. Cor Caroli has one of the strongest magnetic fields among main sequence stars like our Sun. This strong magnetic field is thought to produce large sunspots that cause the brightness of Cor Caroli to vary. Cor Caroli is nearly straight overhead at midnight.

Monday: Procyon, the fourteenth closest star to the Sun and the brightest star in the constellation Canis Minor, is four fists above the southwestern horizon at 9:30 p.m.

Tuesday: Did you get binoculars for the holidays? Like National Pet Day (April 11), World Hamster Day (April 12), or National Peach Cobbler Day (April 13). If so, start using them on some of the easy to find binocular targets found here: https://earthsky.org/astronomy-essentials/best-targets-for-binoculars-moon-planets-nebula-clusters/. The first item on the list, the Moon, is a smart choice because it is full this week, meaning it is out most of the night. One of my favorite binocular objects is the Hyades Open Star Cluster. It is a V-shaped set of stars found about two fists above the western horizon at 9:00 p.m. The bright star Aldebaran is in the upper left-hand part of the V, just below Aldebaran is the double star system Theta1 and Theta2 Tauri. Theta2 Tauri is a blue giant star and Theta1 Tauri is an orange giant star. Through binoculars, you should get a hint of their color. In the mythology of the Maya, the Theta Tauri pair is known as Chamukuy, meaning “small bird” in the Yucatec Maya language.

Wednesday: “The crow rises in the southeast,” said spy number one. “I’m sorry. I don’t recognize that code,” replied spy number two. Spy one exclaimed, “That’s because it’s not a code, you idiot. I’m talking about the constellation Corvus the crow.” This very bad spy movie dialogue is to remind you that Corvus had a very bad life. According to one myth, Corvus brought the god Apollo the news that his girlfriend was seeing someone else. In a classic case of punishing the messenger, Apollo turned the formerly beautifully colored crow black. The box-shaped Corvus is two fists above the south-southeastern horizon at 10:00 p.m.

Thursday: Remember the old saying: April showers bring… meteors. The Lyrid meteor shower peaks next week, with the peak of the peak occurring from Tuesday night to Wednesday morning. The meteors appear to come from a point to the right of the bright bluish star Vega in the constellation Lyra the lyre. This point is about three fists above the east-northeast horizon at midnight tonight and close to straight overhead near dawn. The best time to observe meteor showers is between midnight and dawn. The moon will have set so the sky will be dark. Typically, this is one of the least interesting major meteor showers of the year, with 10-20 bright, fast meteors per hour. However, it is also one of the most unpredictable. As recently as 1982, there were 90 meteors visible during a single hour. In addition, the Lyrid meteor shower has historical interest because it was one of the first ones observed. Chinese records say “stars fell like rain” in the shower of 687 B.C.

The Ellensburg, WA sky for the week of April 4, 2026

Saturday: Because the Earth slowly wobbles like a spinning top, the vernal equinox is slowly moving into the constellation Aquarius. By the year 2597, the vernal equinox will reach the constellation Aquarius, and the “Age of Aquarius” will begin. Until then, we’ll be in “the age of Pisces”. Pisces rises with the Sun around the first day of spring.

Sunday: Astronomers are often fascinated with large objects. Planets that could hold 1000 Earths (Jupiter). Stars that would fill up the entire inner Solar System (Betelgeuse). Galaxies with 400 billion stars (Milky Way). But what about the smallest objects? Until recently, the smallest known stars were about five times the mass of Jupiter. However, in 2023, a pair of astronomers looking at the Orion Nebula think they discovered pairs of binary brown dwarf stars just a little more massive than Jupiter. If confirmed, that could necessitate a substantial change in the accepted theory of star formation. For more on the smallest star, go to https://www.science.org/content/article/astronomers-may-have-spotted-smallest-possible-stars. You can’t see these stars. But you can see the Orion Nebula two fists above the southwestern horizon at 9:00 p.m.

Monday: Antares is a half a fist to the left of the moon at 5:30 a.m., low in the southern sky.

Tuesday: The stars in the Hyades Cluster are all young, as stars are judged, formed in the same cloud of gas, and dust a few hundred million years ago. But just as children move away from home, the stars of the Hyades Cluster are slowly drifting apart. Millennia from now, future sky watchers will see these stars as random points of light in the sky and not as a family. I hope they at least call home every so often. For more information, go to https://www.skyandtelescope.com/astronomy-news/end-hyades-star-cluster/. The Hyades Cluster is two fists above due west at 9:30 p.m.

Wednesday: You probably didn’t know this, but several British New Wave bands were really into astronomy. Take the band “Dead or Alive” (please). The original lyrics to their song “You Spin Me Round (Like a Record)" were actually: “You spin me right round, baby, right round, like the Whirlpool Galaxy, right round, round, round.” (Well, that’s what I thought they were.) The Whirlpool Galaxy was the first galaxy observed to have a spiral shape. Since then, astronomers have discovered that many galaxies, including our own Milky Way Galaxy, have a spiral shape. Go to https://esahubble.org/images/heic0506a/ for more information about the Whirlpool Galaxy. Go to your small telescope to find the Whirlpool Galaxy in the night sky. It is in the constellation Canes Venatici, the hunting dogs. At 10:00 p.m., find Alkaid, the end star of the Big Dipper handle, five and a half fists above the east-northeastern horizon. The Whirlpool Galaxy is two fingers to the upper right of Alkaid.

Thursday: Venus is a half a fist above the west-northwestern horizon and Jupiter is five and a half fists above the southwestern horizon at 9:00 p.m.

Friday: The Lyrid meteor shower peaks later this month. But there will be increased meteor activity in the vicinity of the constellation Lyra until then. The meteors appear to come from a point to the right of the bright bluish star Vega in the constellation Lyra the lyre. This point is about one and a half fists above due northeast at 10:00 p.m. and close to straight overhead near dawn. Go to https://earthsky.org/?p=158735 for more information.

The Ellensburg, WA sky for the week of March 21, 2026

Saturday: Signs of spring: flower buds, leaves on the trees, beetle larvae, and the Spring Triangle. The bright stars Regulus, Arcturus, and Spica rise as evening starts. By 10:00 p.m., Regulus is five fists held upright and at arm’s length above the south-southeast horizon, Arcturus is two fists above the eastern horizon, and Spica is half a fist above the east-southeast horizon. For more on the Spring Triangle, go to https://www.livescience.com/space/vernal-equinox-how-to-see-spring-begin-just-by-looking-at-the-stars.

Sunday: The open star cluster called The Pleiades is less than a half a fist to the upper left of the moon at 9:00 p.m. They are about three fists above the western horizon at this time.

Monday: Venus is a little less than a fist above due west at 8:00 p.m.

Tuesday: The brightest star in the head of Draco the dragon is called Eltanin, based on the Arabic At-Tinnin or “great serpent”. It is currently about 150 light years away. Eltanin is moving towards our Solar System. In 1.5 million years, it will be only 28 light years away and the brightest star in the night sky, nearly as bright as Sirius is currently. Eltanin is three fists above due northeast at midnight.

Wednesday: Jupiter is about a half a fist to the left of the moon throughout the night. They are six fists above the southwestern horizon at 9:00 p.m.

Thursday: The Milky Way is pretty easy to spot in the early spring sky. Just look up. Everything you see in the sky, including that bird that just startled you, is in the Milky Way. But even the path of densely packed stars in the plane of our galaxy that looks like a river of milk is easy to find. Face due west at 9:00 p.m. in a fairly open area and look to your left. The fuzzy Milky Way path starts due south, moves upward past the bright star Sirius, under the bright planet Jupiter, towards the bright star Capella, through W-shaped Cassiopeia and down to due north on your right where the bright star Deneb sits just above the horizon.

Friday: The open star cluster called The Beehive Cluster is right below the moon throughout the night. They are six fists above due south at 9:30 p.m.

The Ellensburg, WA sky for the week of March 14, 2026

Saturday: Venus is a half a fist held upright and at arm’s length above due west at 8:00 p.m.

Sunday: If you want to put somebody off, tell her or him to wait until Deneb sets. At Ellensburg’s latitude of 47 degrees, Deneb is a circumpolar star meaning it never goes below the horizon. At 10:15 p.m., it will be as close as it gets to the horizon, about two degrees above due north. Watch it reach this due north position about 4 minutes earlier each night.

Monday: Many artists have sung the song “Blue Moon”. But few have sung the song “Blue Planet”. It goes, in part “Blue Planet, you saw me standing with 28 others. Rolling around like a barrel. Without close sisters or brothers.” It’s about the planet Uranus, which orbits the Sun in a rolling motion and has 28 moons. 25 of Uranus’ moons are named after characters in works by William Shakespeare and three are from the poem “The Rape of the Lock” by Alexander Pope. Uranus is two and a half fists above due west at 10:00 p.m. It is half a fist below the Pleiades open star cluster.

Tuesday: Ask someone which day in March has the same duration day and night. Go ahead, ask someone. Why are you still reading this? I can wait. If that person said the first day of spring, they are wrong. Today, a few days before the first day of spring, is the date in which day and night are closest in duration in central Washington. Go to https://www.timeanddate.com/sun/ to find the day for your city. It will be close to today for all USA cities.

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 already below the horizon. This makes the Sun appear to rise before it actually rises and appear to set after it actually sets. Second, spring starts when the center of the Sun passes through the point called the vernal 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 spring would still be longer than 12 hours.

Wednesday: Jupiter is six and a half fists above the south-southwestern horizon at 9:00 p.m.

Thursday: If you know exactly where to look in the sky, you can see a few bright planets when the Sun is out. The Solar and Heliospheric Observatory, or SOHO, is always watching the sky when the Sun is out… because it is always watching the Sun! Most of the SOHO images are filtered images of the Sun’s photosphere, the top of the visible layer. But two images, LASCO C2 and C3, place a mask over the Sun to observe the Sun’s corona as well as solar system objects that pass near the Sun, including comets. For more about using SOHO to observe comets, go to https://www.youtube.com/watch?v=K8yUa8_EAUc.

Friday: Look up in the sky. It’s a plane. It’s a bird. No, it’s the vernal equinox. The vernal equinox!? Spring starts at 7:45 a.m. Pacific Daylight Time. The first day of spring is often called the vernal equinox. This label for the day is misleading. The vernal equinox is actually the point in the sky where the Sun’s apparent path with respect to the background stars (called the ecliptic) crosses the line that divides the stars into northern and southern celestial hemispheres (called the celestial equator). This point is in the constellation Pisces the fishes. At the vernal equinox, the Sun is moving from the southern region of background stars to the northern region.

The Ellensburg, WA sky for the week of March 7, 2026

Saturday: Don't forget to set your clocks ahead one hour tonight for the annual ritual called daylight savings. Daylight savings originated in the United States during World War I to save energy for the war effort. But a recent study by two economists shows that switching to daylight savings time may actually lead to higher utility bills. When the economists compared the previous few years of energy bills in the section of Indiana that just started observing daylight savings, they discovered that switching to daylight savings cost Indiana utility customers $8.6 million in electricity. In an even more important consequence of daylight savings, Stanley Coren of the University of British Columbia discovered a 7% jump in traffic accidents on the Monday after we "spring ahead". Blame it on the lost hour of sleep. And, sky watchers will lose even more sleep because the sky stays light for an additional hour.

There are three planets clustered in the sky a half a fist above the western horizon at 6:30 p.m. Venus is by far the brightest of the three. Saturn is to the left of Venus, about one degree away. Most people won’t be able to squeeze their pinky between them. Neptune is the same distance below Venus, but you’ll need large binoculars or a small telescope to see it.

Sunday: Jupiter is six fists above the southwestern horizon at 9:00 p.m.

Monday: “Oooo, they’re little runaways. Orion’s stars moved fast. Tried to make a getaway. Ooo-oo, they’re little runaways,” sang Bon Jovi in his astronomical hit “Runaway. At least that’s what I hear when I listen to the song. After all, it fits the recently calculated trajectory of AE Aurigae, Mu Columbae, and 53 Arietis. Extrapolating the actual motion of these three stars back in time, they were all in the location of the star-forming region called the Orion Nebula a few million years ago. What kicked these stars out? Not paying rent? Excessive partying? No, it was simply gravitational interactions with near-by stars. Find out more about the eviction at http://goo.gl/UeLwKQ. The Orion Nebula is visible with the naked eye from a very dark site, about two fists above the southwestern horizon at 10:00 p.m.

Tuesday: The moon is about one and a half fists above due south at 6:30 a.m. The bright star Arcturus is about a pinky width above it.

Wednesday: “The crow rises in the southeast,” said spy number one. “I’m sorry. I don’t recognize that code,” replied spy number two. Spy one exclaimed, “That’s because it’s not a code, you idiot. I’m talking about the constellation Corvus the crow.” This unbelievably bad spy movie dialogue is to remind you that Corvus had an unbelievably bad life. According to one myth, Corvus brought the god Apollo the news that his girlfriend was seeing someone else. In a classic case of punishing the messenger, Apollo turned the formerly beautifully colored crow black. The box-shaped Corvus is one fist above the southeastern horizon at 11:00 p.m.

Thursday: While you were looking through your underwear drawer for clean socks, some citizen scientists were looking through sky maps obtained by robotic telescopes to find brown dwarfs. The project, called Backyard Worlds: Cool Neighbors, allows anyone with a computer and internet connection to search through thousands of images to find these strange objects that are midway between being classified as large planets and small stars. Some brown dwarfs can have surface temperatures of thousands of degrees Celsius. The recently discovered ones are cooler than the boiling point of water and may even have clouds of water vapor! Read more about the discovery and how you can participate in this project at https://noirlab.edu/public/blog/newly-launched-backyard-worlds/.

Friday: If you are lucky, you may be able to see Mercury just above the eastern horizon at 6:50 a.m.
