Abell 1367, also known as the Leo Cluster, is one of the richest of the nearby galaxy clusters. The cluster is at about 95 Mpc from us. Abell 1367 together with Abell 1656 form the Coma super cluster which is the closest supercluster to the Virgo cluster of which our Local Group is a part. Both of these clusters along with the Hercules cluster appear to be part of a group of galaxies dubbed the Great Wall.
Here’s one fun fact: The larger elliptical galaxy near the center of the picture is NGC3842. It is notable for containing one of the largest black holes ever detected, reported to have a mass of 9.7 billion solar masses.
