The Ellensburg WA sky for the week of 6/8/19

Have you bought your favorite CWU graduate a graduation gift yet? Why not get her or him a star? I don’t mean from one of those organizations that offer to “register the name of YOUR star with the U.S. Patent Office”. No company owns the right to name stars after people. Besides, the stars those companies “name” are so dim you can’t find them. In this column, I’ll pick a constellation and representative star for each of the four colleges at CWU. Then, I’ll briefly tell the story of the constellation and relate that story to the aspect of public service CWU graduates from that college are uniquely qualified to engage in based on my version of sky interpretation. If different couples can have “their” song, then your favorite college graduate can have her or his star

Today: College of Arts and Humanities: You are the people who interpret the world in unique ways. Then, you share those ways with others. According to Greek mythology, Orpheus charmed everyone he met when he played the lyre or harp. After his wife died tragically, he journeyed to the underworld to charm its inhabitants in an effort to win his wife back to the living world. Your service reminder: use your talent to bring joy to others. The constellation Lyra and its bright star Vega should remind you of the power of the arts. Vega is five and a half fists held upright and at arm’s length above the east horizon at 11 p.m.

Sunday: Jupiter will be in opposition tomorrow night. That doesn’t mean that Jupiter refuses to listen. Opposition means that Jupiter is on the opposite side of the Earth as the Sun. When an object is in opposition, it is at its highest point in the sky during the darkest time of the day. Thus, opposition is typically the best time to observe a planet. Jupiter is about two fists above due south at 1 a.m. It is about one fist above the southeast horizon at 10 p.m. Read more about Jupiter’s oppositional behavior at https://www.skyandtelescope.com/observing/jupiter-is-outstanding-at-opposition/.

Monday: College of Business. You are the future movers and shakers. The future CEOs. The future big donors to Central. Auriga represented a king of Athens who happened to be mobility impaired. Instead of sitting around waiting for others to transport him, he took the initiative to invent the four-wheeled chariot. He solved a problem for a special need. Your service reminder: address the problems of those in the most need. To remind you of that, look to the constellation Auriga. Its bright star Capella is about a half a fist above the north-northwest horizon at 11 p.m.

Tuesday: College of Education and Professional Studies. You are the teachers. The craftspeople. The technical experts. Bootes, the herdsman, was such a person. Bootes’ job was to guide the northern constellations to the feeding place and the watering hole. He and his dogs were especially in charge of Ursa Major and Ursa Minor, the greater and lesser bears. Your service reminder: guide others to a better place in life. Look to the constellation Bootes and its bright star Arcturus to remind you of this. Arcturus is five and a half fists above the southwest horizon at 11 p.m.

Wednesday: Mercury and Mars are right next to each other in the evening twilight sky for the rest of the week. Mercury is about four times brighter than Mars. They are about a fist above the west-northwest horizon at 9:30.

Thursday: College of the Sciences. You are the people who will systematically study how the world works. Agriculture is an important scientific application. Each year, farmers must use the findings of science to be successful. Who better to represent the College of the Sciences than Virgo, the goddess of the harvest? Virgo looms large in the sky holding an ear of wheat in her hand. Your service reminder: study the practical aspects of the scientific world. The ear of wheat, and your service reminder, is represented by the bright star Spica. Spica is two and a half fists above the southwest horizon at 11 p.m. Tonight; you’ve got a warrior’s spirit, as well, because the planet Mars, which represents the Roman god of war, is one fist to the right of Spica.

Friday: "Do I have to wake up yet? It's so early!" This next week gives us the earliest sunrises for the northern part of the United States, including Ellensburg.  "Wait, I thought this happened on the longest day of the year, which hasn't occurred yet." Because the Earth's orbit is not a perfect circle, the sunrise and sunset time is not symmetric so the earliest sunrise occurs before the longest day and the latest sunset occurs after the longest day. Go to http://earthsky.org/?p=4027 to read more about this phenomenon. While you are up, check out Saturn, nearly two fists above the south-southwest horizon at 4:30 a.m.
