Messier 31 – the Andromeda Galaxy May 9, 2006Posted by jtintle in Andromeda, Andromeda Galaxy (M31), Deep Space, Space Fotos.
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.
