Constellation of the Month: Andromeda

 

Andromeda is a prominent constellation in the autumn evening sky, passing overhead for many of us in the northern hemisphere during the month of November.  Attached to Pegasus (Alpheratz is usually seen as common to both constellations), it is probably best known for the Andromeda Galaxy, also called M31 in the Messier catalog of deep space objects.  This galaxy is visible to the acute naked eye in places unencumbered by outdoor lights, but you can still easily view it with a good pair of binoculars. There seems to be a scientific consensus that the Andromeda Galaxy and our own Milky Way will collide sometime in the distant future, eventually combining to form a new, non-spiral galaxy.  Near M31 are two "companion" galaxies, M32 and M110...better use a telescope for those.  Andromeda represents the chained maiden in the ancient Greek Perseus myth, as the hero arrives on the winged horse Pegasus to rescue her from the sea monster.  All three are "in the sky" as constellations, along with Andromeda's mother Queen Cassiopeia and father King Cepheus.  Personally, I think all the old myths are kind of lame...they should reconfigure the night sky with figures from Stephen King stories, and throw in a few from Tolkien and some other more modern writers as well...

Next month: another constellation...
