Saturday: The earliest sunset of the year occurs this week, about 4:17 p.m. 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 Sun rise and set time depends on more than its apparent vertical motion. 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.
Sunday: Tonight’s Moon is new. Don’t bother looking for it. The new moon is the phase where the Moon is directly between the Earth and the Sun. Hence the side of the Moon facing Earth is not receiving any sunlight and cannot be seen.
Monday: The young crescent Moon helps mark the location of two planets very low in the southwest sky right after sunset. The Moon is just above the southwest horizon at 4:45 p.m. Mars is about a pinky width to the lower right of the Moon and Mercury is about a half a fist to the upper left of the Moon.
Tuesday: “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 one fist held upright and at arm’s length above the east horizon at 6:30 a.m.
Wednesday: Venus is about two fists and Saturn is about three and a half fists above the south-southeast horizon at 6:30 a.m.
Thursday: When Galileo aimed his telescope towards the sky, he knew of only one Sun-like star: the Sun. By the early twentieth century, Annie Jump Cannon, Williamina Fleming and others had developed a scheme for classifying stars so astronomers could identify other Sun-like stars. But it wasn’t until the last few years that astronomers have discovered planets around some of those Sun -like stars. Some astronomers estimate that one out of every four stars like our Sun may be orbited by Earth-like planets. Of course, the definition of Earth-like typically means a rocky planet about the mass and radius of the Earth. So don’t start saving up for that interstellar vacation yet. But in the next few years, satellites such as Kepler will start imaging Earth-like planets. Not long after that, astronomers will be able to study the atmospheres of those planets and look for clues that the planet might have life.

Friday: Jupiter is four fists above the south horizon at 6 p.m.

The Ellensburg sky for the week of 11/27/10
Saturday: Jupiter is four fists held upright and at arm’s length above due south at a little after 7:00 p.m.
Sunday: This morning’s last quarter moon is in the constellation Sextans the sextant. Sextans is a dim constellation below the constellation Leo that was originated by Johannes Hevelius in 1687. Hevelius continued to use a sextant for studying the sky long after telescopes were available making him the last major astronomer to do major work without a telescope.
Monday: 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 and a half fists above the northeast horizon at 7 p.m., about a fist below the sideways “W” of Cassiopeia.
Tuesday: Are you cold? Tired of the blowing snow? Then get up this morning and look at Saturn, the bright point of light three fists above the southeast horizon. Saturn will not make you warmer. But thinking about its ice moon Enceladus might. Enceladus has numerous geysers that spew ice particles with an aggressiveness that makes the Ellensburg wind feel wimpy – up to 1000 miles per hour. To learn more about Enceladus and its geysers, go to http://www.astronomy.com/en/sitecore/content/Home/News-Observing/News/2008/02/Enceladus%20geyser%20findings.aspx. If you have a small telescope, you may be able to see Enceladus nearly touching the rings of Saturn this morning.
Wednesday: Do you like to look in a nursery and say “it’s a boy” or “it’s a girl”? Not me. I say, “it’s a star”. Of course, I like looking into a stellar nursery – a star forming region such as the Orion Nebula in the middle of Orion’s sword holder. The Orion Nebula looks like a fuzzy patch to the naked eye. Binoculars reveal a nebula, or region of gas and dust, that is 30 light years across. The center of the nebula contains four hot “baby” stars called the Trapezium. These hot stars emit the ultraviolet radiation that causes the Nebula’s gas to glow. The Orion Nebula is three fists above the southeast horizon at 11 p.m. For more information about the Orion Nebula, go to http://astronomy2009.nasa.gov/observe_dec.htm.
Thursday: Sirius, the brightest star in the night sky, is more than one fist above due southeast at 11 p.m.
Friday: Venus is nearly two fists above the southeast horizon at 6 a.m.

The Ellensburg sky for the week of 11/20/10
Saturday: The Nature of Night takes place today from 10 a.m. to 3 p.m. in Black Hall on the CWU campus. There will be planetarium shows, fun nature at night experiments, storytelling, telescopes, and much more. The event is free. The Center for Excellence in Science and Mathematics Education at CWU and various community sponsors work together to put on this event.
Sunday: Well, it is late November. It is time to set the beaver traps before the swamps freeze so you have a supply of warm winter furs. You must be getting ready to do that because the November full moon is known as the full beaver moon. Or maybe you shop for winter coats at a fine Ellensburg business (shop local). If that is the case, you may think the name full beaver moon came about because the beavers, themselves, are preparing for winter. Setting their human traps for…. I guess I shouldn’t continue that thought. Look for an open star cluster called the Pleiades is a half a fist to the upper right of the full beaver moon at 8 p.m.
Monday: Jupiter is four fists held upright and at arm’s length above the south horizon at 8 p.m.
Tuesday: Saturn is three fists above the southeast horizon at 6:30 a.m. The much brighter Venus is almost two fists above the southeast horizon. Spica is less than a half a fist to the upper right of Venus.
Wednesday: 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 it is called Caput Trianguli, the head of the triangle. Triangulum is seven fists 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: 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: 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.

The Ellensburg sky for the week of 11/13/10
Saturday: Imagine Opie and Andy Taylor walking down the dirt path at night to that fishing hole in the sky. (No, that is not a euphemism for death.) 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 10 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 in my opinion.
Sunday: Jupiter is three and a half fists above the south-southeast horizon at 9 p.m.
Monday: Deneb Kaitos, the "tail of the whale," swims through the southern sky tonight (and many other nights, of course). The moderately bright orange star forms the tail of Cetus, the whale. At 9 p.m., it is three and a half fists above the south horizon, about a fist to the left of the much brighter Jupiter.
Tuesday: The Leonid meteor shower peaks tonight and tomorrow morning. These meteors appear to come from a point in Leo the lion. This point is about one fist 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. Even if the weather cooperates, this will not be a great night to see a lot of meteors because the sky will be illuminated by the waxing gibbous moon. 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://antwrp.gsfc.nasa.gov/apod/ap021116.html to see a picture of Comet Tempel-Tuttle. This year’s shower is expected to be much more active than usual with up to 500 meteors per hour visible throughout the night. As your Mother might say, dress warm and sit in a comfortable chair for maximum enjoyment. Even if there are only a couple dozen meteors visible per hour, you’ll want to enjoy it.
Wednesday: While your family is lining up at 6 a.m. this morning to use the shower, two planets and a bright star are lining up in the southeast sky. Venus, the brightest point of light in the sky, is one fist above the southeast horizon. The star Spica is slightly to the upper right of Venus and Saturn is one and a half fists above Venus.
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 four and a half fists above the west horizon, in the middle of the neck of Cygnus the swan.
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 Chicago resident doubts the existence of the wind.
Tomorrow, November 20, the Nature of Night takes place from 10 a.m. to 3 p.m. in Black Hall on the CWU campus. There will be planetarium shows, fun nighttime projects, storytelling, cookies and much more. The event is free. Call 963-2929 for more information. The Center for Excellence in Science and Mathematics Education at CWU and various community sponsors work together to put on this event. When you are there, ask about the safe way to look at the Sun. Even though this is called Nature of Night, without day, there is no night. And without Gladys Knight, there are no Pipps.

The Ellensburg sky for the week of 11/6/10
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: The North Taurid meteor shower peaks for the next few late nights and early mornings with the night of the 12th being the peak of the peak. This is not a prominent shower but it occasionally produces a couple of bright “fireballs”, larger rocks that take a few seconds to burn up in the atmosphere. 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 nearly six fists above the southeast horizon at 11 p.m. You can follow this point throughout the night as it will remain midway between the bright star Aldebaran (pronounced Al-deb’-a-ran) and the open star cluster, the Pleiades. If you miss the peak this week, don’t worry. Taurid meteor showers result in a slight increase on meteor activity from mid-October to the beginning of December.
Monday: Jupiter is four fists above due south at 8:30 p.m.
Tuesday: Did you look up Caroline Herschel and Clyde Tombaugh based on last week’s Halloween costume suggestion? Caroline Herschel was an 18th and 19th century astronomer who discovered three nebula and eight comets. Clyde Tombaugh discovered Pluto. They make much better, and more realistic, heroes than Lady Gaga, Ironman, and Christine O’Donnell.
Wednesday: Saturn is two fists above the east-southeast horizon at 6 a.m.
Thursday: We wish you a Merry Martinmas. We wish you a Merry Martinmas. We wish you a Merry Martinmas. And a happy Thursday. 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.
Friday: The constellation Lepus the hare is right under the feet of Orion. At 11 p.m., the middle of the hare is one fist above the southeast horizon. Rigel, the brightest star in the constellation Orion, is just above the head of the hare.
Wait a minute. We got all the way to the end of the week with no Moon phase summary? How can that be? There are 29.5 days between the same Moon phase in two different cycles. That means about 7.5 days between the phases new, first quarter, full and last quarter. Since a week is seven days, there are some weeks in which none of the main phases occur. This week, the Moon was always in the waxing crescent phase.
