Andromeda constellation. Optical image of the constellation Andromeda. North is at top. The Andromeda Galaxy (M31) is the small fuzzy blob at centre. This large spiral galaxy is around million light years away. At lower right is the constellation Pegasus, the winged horse, centred on the square of four bright stars. The upper left star (Alpheratz, or Alpha Andromedae) is in Andromeda, not Pegasus. The other three stars, clockwise from Alpheratz, are Scheat (Beta Pegasi), Markab (Alpha Pegasi) and Algenib (Gamma Pegasi). The two bright stars at lower left are in Aries, with the faint constellation Triangulum above them. Cassiopeia is at upper centre.
