A band of dark dust has earned the spiral galaxy M64 a nickname: the Black-Eye galaxy. The band is clearly visible in this close-up of the center of M64, snapped by Hubble Space Telescope. Research suggests the dark dust is left over from a smaller galaxy that M64 incorporated into its own disk. The galaxy is in the constellation Coma Berenices. [NASA/Hubble Heritage Team (AURA/STScI)]
