The Coma Cluster shown with sorrounding intergalactic flux nebula (IFN)
The Coma Cluster (Abell 1656) is a large cluster of galaxies that contains over 1,000 identified galaxies.
Along with the Leo Cluster (Abell 1367), it is one of the two major clusters comprising the Coma Supercluster.
It is located in and takes its name from the constellation Coma Berenices.
The cluster's mean distance from Earth is 321 million light years.
Its ten brightest spiral galaxies have apparent magnitudes of 12–14 that are observable with amateur telescopes larger than 20 cm.
The central region is dominated by two giant elliptical galaxies: NGC 4874 and NGC 4889.
The cluster is within a few degrees of the north galactic pole on the sky.
Most of the galaxies that inhabit the central portion of the Coma Cluster are ellipticals. Both dwarf and giant ellipticals are found in abundance in the Coma Cluster. (wiki)
