M 64 – The Black Eye Galaxy

Description:

The Black Eye galaxy presents a rather unusual aspect, a consequence of its particular structure. It has an annular structure with two counter-rotating discs of equal mass made of tightly wound spiral arms. It is one of the few galaxies that does not belong to a cluster or group and is therefore gravitationally isolated.

There is a supermassive black hole in its center with a mass estimated between 18 and 42 million times the mass of our sun.
