The Ellensburg WA sky for the week of 4/8/17
Saturday: Mercury is a half a fist held upright and at arms length above the west-northwest horizon at 8:30 tonight. Mars is a little bit higher, two fists above the west horizon.
Sunday: 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 many galaxies, including our own Milky Way Galaxy, have a spiral shape. Go to http://www.spacetelescope.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 p.m., find Alkaid, the end star of the Big Dipper handle, six fists above the north-northeast horizon. The Whirlpool Galaxy is two fingers to the upper right of Alkaid.
Monday: Poor Jupiter. Objects from space just keep bombarding it. On March 17 last year, two amateur astronomers, unbeknownst to each other, had their cameras aimed at Jupiter when a brief flash of light appeared on the limb. This is the fifth time such an impact has been observed in the past ten years. For more information, go to http://goo.gl/6eV7ql. Tonight, nothing large is probably hitting Jupiter in the Solar System. But the Full Moon seems to come close to hitting Jupiter in the night sky. At 9 p.m., Jupiter is a half a fist to the upper right of the Moon.
Tuesday: The Lyrid meteor shower peaks next week. But there will be increased meteor activity for the next two weeks in the vicinity of the constellation Lyre. 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 and close to straight overhead near dawn.
Wednesday: It you didn’t run the Yakima River Canyon Marathon nearly two weeks ago, satisfy that marathon craving by attending a virtual Messier Marathon. Charles Messier (pronounced messy a) was an 18th century French astronomer best known for his catalog of 110 nebulae and star clusters. Amateur astronomers love to find as many of these as they can in one night. During the online Messier Marathon, you’ll see the images broadcast on the Internet. The fun starts this morning at 11:30 a.m. Pacific Daylight Time (when astronomers on the nighttime side of Earth point their telescopes towards interesting celestial objects).

Thursday: Saturn is two fists above the south horizon at 6 a.m.
Friday: Antares is one fist below the Moon tomorrow morning at 6 a.m.
