Description

The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant (z = 0.022) in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, which is hundreds of millions light years long and is one of the largest known structures in the universe.

Most dense galaxy clusters are composed mostly of elliptical galaxies. The Leo Cluster, however, mostly contains spiral galaxies, suggesting that it is much younger than other comparable clusters, such as the Coma Cluster. It is also home to one of the universe's largest known black holes, which lies in the center of NGC 3842, visible here. The black hole is 9.7 billion times more massive than the Sun.

There appears to be a number of sub-populations within the Leo Cluster. The first consists of elliptical galaxies that seem to be roughly as old as the universe. The second sub-population contains red-sequence lenticular (lens shaped) galaxies whose ages are directly tied to their mass. The third and final sub-population is of galaxies where star formation is still taking place, and are morphologically distributed.
