The Ellensburg, WA sky for the week of November 16, 2019


Saturday: 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 held upright and at arm’s length above due south at 10:20 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 ranking in my opinion. 

Sunday: The Leonid meteor shower peaks tonight. These meteors appear to come from a point in the constellation 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. The waning gibbous Moon will illuminate the sky and interfere with viewing the dimmer meteors. The Leonid meteors are particles from the tail of Comet Tempel-Tuttle, a comet discovered by Ernst Tempel and Horace Parnell Tuttle in 1866. These are exceptionally fast moving meteors – over 150,000 miles per hour! Go to https://earthsky.org/?p=29831 to read everything you need to know about the Leonid meteor shower. As your Mother might say, dress warm and sit in a comfortable chair for maximum enjoyment.

Monday: Lieutenant Worf, the Klingon Starfleet officer on Star Trek: The Next Generation, might say “Today is a good day to die.” But Deneb, the bright supergiant star in Cygnus the Swan would say “two million years from now is a good day to die.” This may seem like a long time. But, compared to the lifespan of most stars, two million years from now is as close as tomorrow. For example, the Sun will last about five billion years. Small stars known as red dwarfs may last trillions of years. Prepare your astronomically short goodbyes to Deneb tonight at 7 o’clock when it is seven fists above the western horizon.

Tuesday: Lacerta, the faint lizard constellation, is straight overhead at 6:30 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.

Wednesday: At 5:00 p.m., Venus is a half a fist above due southwest. Jupiter is about a half a fist to the upper left of Venus. The much dimmer Saturn is one and a half fists above the south-southwestern horizon.

Thursday: Mercury, Mars, and the star Spica make a line segment pointing away from the soon to be rising Sun. At 6:30 a.m., Mercury is nearly one fist above the east-southeastern horizon, Mars is one and a half fists above the southeastern horizon, and Spica is two fists above due southeast.

Friday: The Nature of Night event takes place tomorrow from 10 a.m. to 2 p.m. in the Science Building at the intersection of Wildcat Way and 11th Avenue, J-9 on the map found at http://www.cwu.edu/facility/campus-map. There will be planetarium shows, fun nighttime projects, animals, cookies and much more. Go to cwu.edu/sciences for more information.
