M104 - The Sombrero Galaxy

M31, the Andromeda Galaxy, is the closest large galaxy to our own Milkyway galaxy. At a distance of approximately 2.2 million light years and at a size of nearly 65,000 light years across, this galaxy is easily seen as a naked eye object in the night sky and appears as a faint fuzzy patch in the constellation, Andromeda. The two smaller fuzzy objects in the image above are the satellite galaxies, M32 and M110.
