The Black Eye Galaxy (also called Sleeping Beauty Galaxy; designated M64) absorbed a satellite galaxy that collided with it, perhaps more than one billion years ago. Active formation of new stars is occurring in the shear region where the oppositely rotating gases collide, are compressed, and contract. It is approximately 17 million light years from Earth. The inner region has a radius of only approximately 3,000 light-years, while the outer section extends another 40,000 light-years.
A collision of two galaxies has left a merged star system with an unusual appearance as well as bizarre internal motions. Messier 64 (M64) has a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus, giving rise to its nicknames of the "Black Eye" or "Evil Eye" galaxy.
