M64 – The Black Eye Galaxy

Messier 64, also known as the Black Eye galaxy features a dark and prominent dust lane.
The galaxy can be found in the constellation Coma Berenices and lies at a distance of 24 million light years.

Recent studies of the galaxy have revealed that the gas in the outer regions of M64 rotates in the opposite direction from the gas and stars in the inner region of the galaxy.
Current explanation for this behaviour is the possible collision and absorption of another galaxy.
