The Andromeda Galaxy (all night)
In late October, the Andromeda Galaxy is climbing the eastern sky during evening. This large spiral galaxy, also designated Messier 31 and NGC 224, is 2.5 million light years from us, and covers an area of sky measuring 3 by 1 degrees (or six by two full moon diameters)! Under dark skies, M31 can be seen with unaided eyes as a faint smudge located 1.4 fist diameters to the left (or 14 degrees to the celestial northeast) of Alpheratz, the star that forms the left-hand (northwestern) corner of the square of Pegasus. The three
westernmost stars of Cassiopeia, Caph, Shedar, and Navi (Gamma Cas), also conveniently form an arrow that points towards M31. Binoculars will reveal the galaxy better. In a telescope, use low magnification and look for M31's two smaller companion galaxies, the foreground Messier 32 and more distant Messier 110.
