. # 17 (yellow for the Local Group) The Andromeda galaxy, M31, and one of its satellite galaxies, M32. Now we have to leave our Galaxy and proceed to the ones near us. Our sister galaxy, Andromeda, consists of about 3 billion stars like our Milky Way, and is about 2 million light-years away. As with the Crab, the objects are so faint that they had to be enhanced by computer to better see them, even though, in apparent size, M31 is about the same size as the full Moon. #17 from IMG0013.pcd, taken 09/10/93, f/6.3, ASA 100, 7min
