Meteors will put on a fine show in December

For December, the full moon, the “Long Night Moon” occurs on Dec. 3. The last quarter moon is on Dec. 10. The waning crescent moon passes just north of Mars on the morning of Dec. 13, and then north of Jupiter the following morning. This is also the peak for the best meteor shower of the year.

The Geminids will begin coming out of the northeast shortly after sunset and peak at about a meteor a minute about 3-4 a.m. on the 14. The moon is new Dec. 18. First quarter moon is on Dec. 26.

Mercury and Saturn are briefly visible just after sunset during the first week of December, but are lost in sun’s glare for the rest of the month. Venus is also lost in the sun’s glare, to reappear in the dawn in early 2018. Mars and Jupiter are in the dawn sky, with closer Mars overtaking more distant Jupiter throughout the month, with the two only three degrees apart on New Year’s morning.


This fine shot of the “Eye of God” by EAAA members Chris and Gina Gomez probably anticipates what our own solar system will look like 6 billion years hence, when the evolved red giant sun passes through a similar cosmic strip tease stage.

The square of Pegasus dominates the western sky. South of it are the watery constellations of Pisces (the fish), Capricorn (Sea Goat), Aquarius (the Water Bearer) and Cetus (the Whale). Below Aquarius is Fomalhaut, the only first magnitude star of the southern fall sky. It is the mouth of Pisces Australius, the Southern Fish. Between the foot of Aquarius and Fomalhaut is the Helix Nebula, the closest planetary nebula.

The constellation Cassiopeia makes a striking W in the northwest. She contains many nice star clusters for binocular users in her outer arm of our Milky Way, extending to the northeast now. Her daughter, Andromeda, starts with the northeast corner star of Pegasus’ Square, and goes northeast with two more bright stars in a row. It is from the middle star, beta Andromeda, that we proceed about a quarter the way to the top star in the W of Cassiopeia and look for a faint blur with the naked eye.

M-31, the Andromeda Galaxy, is the most distant object visible with the naked eye, lying about about half their distance. Their 2.5 million light years distant. appearance in November in Overhead, Andromeda’s hero, classical times was associated Perseus, rises.

The EAAA is glad to announce that we will be hosting year around deep sky observing sessions on Saturday evenings for the public at the Big Lagoon State Park.

Our next gazes are scheduled for Dec. 9, and Jan. 6.

While the naked eye, dark adapted by several minutes away from any bright lights, is a wonderful instrument to stare up into deep space, far beyond our own Milky Way, binoculars are better for spotting specific deep sky objects.

Also notable is wonderful video exploring the sky, available from

Hubble Space Telescope website at: http://hubblesite.org/explore_ astronomy/tonights_ sky/
