The Andromeda Galaxy

The famous Andromeda Galaxy, also known as M31, takes its name from its host constellation. Located 2.5 million light-years away, this vast starry spiral is the closest galaxy similar to our own. Between May 25 and July 26, 2008, NASA’s Swift satellite acquired 330 images of M31 in ultraviolet light. The images reveal dense clusters of hot, young stars, especially plentiful in an enormous ring about 150,000 light-years across. As in our own galaxy, M31's disk and spiral arms contain most of the gas and dust needed to produce new generations of stars. Viewing the galaxy in ultraviolet light allows scientists to study M31's star-formation processes in greater detail than ever before. Watch the video for a tour of M31.
