M31, better known as the Andromeda galaxy, is our nearest spiral neighbor. Visible to the naked eye on a clear moonless night, M31 appears nearly three degrees wide in our sky — that’s six times the width of the full moon! Because of M31’s large angular size, this picture was created by stitching together data from multiple SDSS images. A new dwarf spheroidal galaxy was recently discovered in M31 using SDSS photometry data and follow-up observations. This puts the count at 10 known satellite galaxies contained within M31.
