Explanation: Andromeda is the nearest majorgalaxy to our ownMilky Way Galaxy. Our Galaxy is thought to look much likeAndromeda. Together these two galaxies dominate theLocal Group of galaxies. The diffuse light fromAndromedais caused by the hundreds of billions ofstars that compose it. The several distinct stars that surround Andromeda's image are actually stars inour Galaxythat are well in front of the background object.Andromeda is frequently referred to as M31 since it is the 31st object onMessier's list of diffuse sky objects.M31 is so distant it takes about two million years for light to reach us from there. Although visible without aid, theabove image of M31 was taken with a standard camera through a small telescope. Much about M31remains unknown, including how it acquiredits unusual double-peaked center.
