Description

The Coma Cluster (Abell 1656) is a large cluster of galaxies that contains over 1,000 identified galaxies.
The cluster's mean distance from Earth is 99 Mpc (321 million light years).
Dark Matter theory began by looking here....

I annotated 196 on this picture, please see revision B for annotated version.
