M 64 (The Black Eye Galaxy)


M 64  (The black Eye Galaxy)

M 64 is an unusual spiral galaxy in the constellation of Coma Berenices at an uncertain distance. One estimate places M 64 at 24 MLY.

M64’s rotation is not uniform. Its inner radius of 3000 LY spins clockwise while the galaxy’s outer 40,000 LY spins in the other direction. The huge dark gas cloud, that gives this galaxy its name, and the unusual rotation is probably the results of a distant merger with another galaxy.
