M64 is a type 2 Seyfert galaxy lying at a distance of 17 million light-years from Earth in the constellation Coma Berenices. It is known as "The Black Eye Galaxy" due to its prominent, compact dust lane. The galaxy actually has two disks, a brighter inner one and a dimmer outer one, which are counter rotating relative to each other.
