  The Andromeda Galaxy (M31 or NGC 224) is a spiral galaxy approximatly 2.5 million light-years away in the constellation Andromeda. It is the nearest spiral galaxy to our own and is approaching our Milky Way at about 120km/s, so it is one of the few blue shifted galaxies. If it is on a collision course, the impact is predicted to occur in about 3 billion years, in which case the two galaxies will likely merge to form a giant elliptical galaxy. M31 harbors a dense and compact star cluster at its very center, containing a black hole with 10^8 solar masses.
