Andromeda VIII (And VIII / 8) is agalaxy discovered in August 2003. It is a companion galaxy to theAndromeda Galaxy, M31, and evaded detection for so long due to its diffuse nature. The galaxy was finally discovered by measuring theredshifts of stars in front of Andromeda, which proved to have differentvelocities than M31 and hence were part of a different galaxy.[citation needed]
As of at least 2006, the actuality of And VIII as a galaxy has not yet been firmly established (Merrett et al. 2006).[2]
