Discovered by French astronomer Guillaume Le Gentil in 1749, the galaxy Messier 32 (M32) is located within the constellation Andromeda. It’s a companion of the much larger Andromeda Galaxy (M31).

M32 is approximately 2.5 million light-years from Earth. Because it appears from here to be superimposed over the spiral arms of the Andromeda galaxy (top right portion of photo), it’s probably closer to Earth than is M31, as spectroscopic observations also suggest. The center of this elliptical dwarf galaxy contains a supermassive black hole. Photo taken on October 10, 2012.
