The Ellensburg sky for the week of 11/30/13

Saturday: “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 about November 29 to December 17. 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 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 about a half a fist held upright and at arm’s length above the east-northeast horizon at 6:30 a.m.

Sunday: How would you like a moon sandwich for breakfast? This morning’s waning crescent moon is sandwiched between two planets low in the southeastern sky at 6:45 a.m. Saturn is a half a fist to the upper right of the moon and Mercury is less than a half a fist to the lower left of the moon.

Monday: Jupiter is two fists above the east horizon at 9 p.m.

Tuesday: Have you been 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 six fists above the northeast horizon at 6 p.m., about a fist below the sideways “W” of Cassiopeia and three fists above the bright star Capella.

Wednesday: For the next two evenings, the bright planet Venus will be near the moon. Tonight it is about a fist and a half to the left of the moon. Tomorrow night, it is less than a fist below the moon.

Thursday: Mars is four and a half fists above the south-southeast horizon at 6:30 a.m. If you are more of a night owl, you can look for it a half a fist above the east horizon at 1:30 a.m.

Friday: Is that favorite astronomy-loving relative of yours asking for a telescope this Christmas? Well, she’s your favorite so get her what she wants with cost being no object. But if that so-so relative of yours would like a telescope, look no further than this Sky and Telescope article about low cost telescopes http://goo.gl/40zd6. The authors review and recommend three telescopes for under $100 at the time of publication. If your hated acquaintance wants an astronomy gift, show them a copy this column. After such a dud “gift”, you’ll never hear from them again. And that may be the best gift of all.

The Ellensburg sky for the week of 11/23/13

Saturday: The Nature of Night event takes place from 10 a.m. to 3 p.m. in the Science Building on the CWU campus. There will be planetarium shows, fun nighttime projects, telescopes, animals, cookies and much more. Have you ever wanted to meet an owl? You can at this event. The event is free. You could go to http://www.cwu.edu/cesme/nature-night for more information. But why go to a computer. Instead, go directly to the Science Building, I-8 on the map found at http://www.cwu.edu/newmap.html. The Center for Excellence in Science and Mathematics Education gets help from various community organizations to put on this event.

Sunday: Are you disappointed because you are not going anywhere for Thanksgiving? Why not take a (virtual) trip to outer space using Google’s new visualization tool called 100,000 Stars. It shows the stars in our neighborhood in a very good simulation of 3-D. The Sun is initially at the center. If you zoom in, you can click on neighboring stars and learn more about them. For more information and a link to the tool, go to http://goo.gl/hg6Oc.

Monday: Jupiter is one and a half fists held upright and at arm’s length above the east-northeast horizon at 9 p.m.

Tuesday: The moon has some bright neighbors this morning at 6 a.m. Mars is a little more than a fist to the left of the moon. And Regulus is a little more than a fist to the upper right of the moon.

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 of its 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 straight overhead at 9 p.m.

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-northeast horizon and Andromeda is about seven fists above the east horizon at 7 p.m.

Friday: Spica is about a finger’s width to the lower left of the moon at 6 a.m. People in some parts of Alaska will see the moon occult, or block, Spica.

The Ellensburg sky for the week of 11/16/13

Saturday: The Leonid meteor shower peaks tonight and tomorrow morning. These meteors appear to come from a point in the constellation Leo the lion. This point is about one fist held upright and at arm’s length above the east-northeast horizon at midnight tonight. You can follow this point throughout the night and into the morning, as it will remain about one fist above the bright star Regulus. The Leonid meteors are particles from the tail of Comet Tempel-Tuttle, a comet discovered by Ernst Tempel and Horace Parnell Tuttle around January 1, 1866. Go to http://goo.gl/OPP6D to see a picture of Comet Tempel-Tuttle. As your Mother might say, dress warm and sit in a comfortable chair for maximum enjoyment. Even if there are only a dozen meteors visible per hour, you’ll want to enjoy it.

Sunday: Humm. Early Sunday morning choices. Roll out of bed just before church. Or get up early to see Comet ISON. The comet, discovered in 2012, brightened significantly last week and is approaching naked eye status in the early morning sky. This morning at 6 a.m., ISON will be about a finger width above the bright star Spica, a fist and a half above the southeast horizon. Tomorrow morning at 6 a.m., ISON will be just below Spica, heading towards its closest approach to the Sun on November 28. By early December, Comet ISON should be visible in the early evening sky. For updates on Comet ISON’s location and activity, go to http://www.spaceweather.com/. By the way, ISON stands for International Scientific Optical Network, a series of telescopes in 11 countries. And, yes, you should get up early to see ISON. Use binoculars to increase your chances.

Monday: When you think of space, the first image that comes to mind is a few large, massive bodies surrounded by a lot of empty space. After all, it is called “outer space”, not “outer stuff”. But that so-called empty space is filled with powerful radiation and high-speed sub-microscopic particles. Much of this is dangerous to life. However, many planets, including Earth, have a shield against radiation and particles called a magnetic field. Jupiter’s magnetic field is the strongest of all the planets. Find Jupiter one fist above the east-northeast horizon at 9 p.m. For more information about magnetic fields, go to http://goo.gl/OYShj.

Tuesday: Venus is one fist above the south-southwest horizon at 5 p.m.

Wednesday: Sunday: Most constellations don’t look like the object their name refers to. Most constellations don’t have such a simple to object to emulate as Triangulum. As you probably guessed, Triangulum is shaped like a princess. Wait…. Just a second…. I read my book wrong. Triangulum is shaped like a thin isosceles triangle. Mothallah is the only named star in the constellation. In Latin this star is called Caput Trianguli, the head of the triangle. Triangulum is seven fists held upright and at arm’s length above the south horizon at 9 p.m. It is pointing down and to the right with Mothallah being the southernmost star at this time of night. The Triangulum Galaxy can be seen with binoculars about a half a fist to the right of Mothallah.

Thursday: You know winter is coming when Orion is visible in the evening sky. It is about a fist above the east-southeast horizon at 9 p.m.

Friday: The Nature of Night event takes place tomorrow from 10 a.m. to 3 p.m. in the Science Building on the CWU campus. There will be planetarium shows, fun nighttime projects, telescopes, animals, cookies and much more. Go to http://www.cwu.edu/cesme/nature-night for more information.

The Ellensburg sky for the week of 11/9/13

Today: The Northern Taurid meteor shower peaks this weekend. You’ll want to stay up late to see the most meteors because the waxing crescent moon doesn’t set until about midnight so the late night sky will be moon-free. Under the best conditions, you can expect about 10 meteors an hour with some of them being bright fireballs. A few weeks ago, the related Southern Taurid meteor shower produced many fireball sightings in the southwest United States. Meteor showers are named after the constellation from which the meteors appear to originate. These meteors appear to come from a point in Taurus the bull, near the open star cluster called the Pleiades. This point is about six fists held upright and at arm’s length above the southeast horizon at 11 p.m. You can follow this point throughout the night, as it will remain one fist the V-shaped Hyades Cluster with its bright star Aldebaran (pronounced Al-deb’-a-ran). 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.

Sunday: “I’m a little teapot short and stout. All this week, Venus is on my spout.” All this week, the bright planet Venus is on the spout of the teapot-shaped asterism Sagittarius. It is one fist above the south-southwest horizon at 5 p.m.

Monday: We wish you a Merry Martinmas. We wish you a Merry Martinmas. We wish you a Merry Martinmas. And a happy Monday. 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 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.

Tuesday: Jupiter is one and a half fists above the east-northeast horizon at 10 p.m.

Wednesday: 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 above due south at 10:30 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 20th best TV theme song of all time by ign.com. That’s too low of a rating in my opinion.

Thursday: Have you even seen a Black Hole? Neither have scientists. But they have seen the effects of a Black Hole. Black holes have a strong gravitational influence on anything that passes close to them, including light. Cygnus X-1, the first Black Hole candidate ever discovered, is six fists above the west horizon at 7 p.m., in the middle of the neck of Cygnus the swan. NASA launched the Chandra X-ray observatory in 1999 to study black hole candidates and other high energy events.

Friday: I am guessing that some of you don’t like the line of reasoning from Thursday: that seeing the effects of a Black Hole is good enough to claim there are Black Holes. You have never seen the wind. But, you have seen the effects of the wind. And no Ellensburg resident doubts the existence of the wind.

The Ellensburg sky for the week of 11/2/13

Saturday: Don’t forget to “fall back” tonight. Before you fall back on to your bed, set your clock back one hour to the real time. Daylight savings ends early Sunday morning at 2 a.m. This means one more hour of sky watching at night 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 savings time was first utilized during World War I as a way 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 savings and some did not. But, it was not implemented with any uniformity as to when it should start and stop. The Uniform Time Act of 1966 codified the daylight savings rules.

Sunday: Lacerta, the faint lizard constellation, is straight overhead at 9 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. Chinese know this group of stars as a flying serpent or dragon.

Monday: Jupiter is rising from the northeast horizon at 9 p.m. By 11 p.m., it is two fists above the east horizon.

Tuesday: Venus is about a fist to the left of the crescent moon at 5 p.m. Tomorrow night at this time, Venus will be less than a fist below the moon.

Wednesday: Did you look up Jocelyn Bell Burnell and Antony Hewish based on last week’s Halloween costume suggestion? Jocelyn Bell Burnell is a Northern Irish astrophysicist. As a postdoctoral student, she discovered the first radio pulsar, a super massive rapidly rotating star. Antony Hewish was her supervisor. Hewish and a colleague shared the 1974 Nobel Prize in physics for the discovery while Bell, who made the actual observations, was not listed. Many astronomers criticized this omission, noting that her observation was one of the greatest astronomical discoveries of the twentieth century.

Thursday: 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 10-13. For more information, visit http://goo.gl/0hwFQf or visit MIT.

Friday: When Napoleon Dynamite danced to the Alphaville song, “Forever Young” at his prom, he didn’t know he might have been learning about the giant asteroid Vesta. According to the latest pictures from the Dawn spacecraft, Vesta is continually stirring up its outermost layer bringing fresh material to the surface. This makes Vesta look “forever young, Vesta wants to be forever young. Vesta wants to live forever, forever, and ever.” Go to http://www.universetoday.com/98284/vesta-looks-forever-young/ for more information. Vesta is visible with binoculars, about midway between Mars and Spica, three fists above the east-southeast horizon at 5:30 a.m. Mars is the bright and reddish point of light four fists above the southeast horizon. NASA built and launched Dawn in 2007 for less than half the cost of a new NFL football stadium. Its mission is to study the early solar system by gathering data from two asteroids that have remained relatively unchanged from their formation.

The Ellensburg sky for the week of 10/26/13

Saturday: Dead October flowers lead to November meteor showers. While the Leonid meteor shower is the big name event, the few bright and surprisingly colorful fireballs per hour you can see during the typical Southern and Northern Taurids meteor showers may make it worth your while to stay up. These two showers overlap from about October 19 to November 19. Meteor showers are named after the constellation from which the meteors appear to originate. These meteors appear to come from a point in Taurus the bull. This point is about four fists held upright and at arm’s length above the southeast horizon at 11 p.m. You can follow this point throughout the night, as it will remain one fist to the right of the V-shaped Hyades Cluster with its bright star Aldebaran (pronounced Al-deb’-a-ran). 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.

Sunday: The Stargate movies and TV shows have access to a portal to other planets. Harry Potter has access to a portal to the Chamber of Secrets. You have access to a Portal to the Universe. This portal is not in Moaning Myrtle’s bathroom but on the web at http://www.portaltotheuniverse.org/. It is a repository of up-to-date astronomy news, blogs, and podcasts. A recent story highlights the discovery of a planetary system in which the planets do not orbit around the equator of the star. Astronomers are surprised by this misalignment because it goes against their current theories of solar system formation. Read more about the discovery at http://goo.gl/oI6qeq.

Monday: Jupiter is six fists above the south horizon at 7 a.m.

Tuesday: At 7 a.m., the moon, Mars, and Regulus make a small, nearly equilateral triangle about four fists above due southeast. The bright star Regulus is at the top of the triangle.

Wednesday: Late October to-do list. Buy costume. Check. Watch Orion rise in the east-southeast sky just before midnight. Check. Take kids to Boo Central. Double check. Once again, CWU clubs and organizations will turn the SURC Ballroom into a monstrously fun, safe, and educational place to trick or treat. In fact, it will be “science or treat” for the 4 to 9-year-old kids who visit the CWU astronomy and physics club booths. Boo Central runs from 5:00 to 7:00 p.m. in the SURC Ballroom on the CWU campus tomorrow night. Contact Campus Activities at 509-963-1450 for more information.

Thursday: Halloween. The pumpkins. The candy. The children going door-to-door dressed up as their favorite astronomers Jocelyn Bell Burnell and Antony Hewish. At least they should because Halloween is, in part, an astronomical holiday. Halloween is a “cross-quarter date”, a day approximately midway between an equinox and a solstice. Historically, the Celts of the British Isles used cross-quarter dates as the beginnings of seasons. For the Celts, winter began with Halloween. So when all those little Burnells and Hewishs come to your door tomorrow night, honor the Celts and give them a wintry treat. If they ask you for a trick, point out Venus, one fist above the south-southwest horizon at 6 p.m.

Friday: Happy Celtic New Year! Many historians think that this day, 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 positional information in this column about stars and planets is typically accurate for the entire week.

The Ellensburg sky for the week of 10/19/13

Saturday: Venus is about a fist above the southwest horizon at 6:30 p.m. The bright star Antares is more of a challenge to find, about a half a fist to the lower right of Venus.

Sunday: The Orionid meteor shower consists of the Earth colliding with pieces of the remains of Halley's Comet's tail. This shower peaks for the next two nights and early mornings. This is not a meteor shower that 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. In addition, the nearly full moon will illuminate the sky and obscure the dimmer meteors. 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 three fists above the southeast horizon at 1 a.m. tonight. 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 http://goo.gl/35wHaN.

Monday: Halloween is next week so make sure you load up on peanut clusters, almond clusters, and open star clusters. 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 p.m. Containing over 300 stars; the Hyades cluster is about 150 light years away and 625 million years old. The Pleiades Cluster, a little more than three fists above due east, is larger at over 1000 stars and younger. Compared to our 5 billion year old Sun, the 100 million year age of the Pleiades is infant-like. The moon will help you find these clusters. This morning at 6:30 a.m., the Pleiades cluster is less than one fist to the upper right of the moon and the Hyades cluster is about one fist to the upper left of the moon. Tomorrow morning, the moon sits in the “V” of the Hyades cluster.

Tuesday: The wintertime constellation Orion is making its way into the evening sky. Nearly the entire constellation has risen by 11:30 p.m. and its bright star Betelgeuse is one fist above due east at 11:20 p.m. You may still see an occasional Orionid meteor for the next two weeks in this region of the sky.

Wednesday: The Milky Way makes a faint white trail from due northeast through straight overhead to due southwest at 9 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. As you started your visual journey, you may have noticed Jupiter rising above the east-northeast horizon.

Thursday: Jupiter is less than a fist above the east-northeast horizon at 11 p.m.

Friday: “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 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 10 p.m. The much brighter Fomalhaut is a fist and a half below Skat. And, it’s not fun being below Skat.
