A close view of the central regions of the VirgoCluster, showing the string of galaxies known as Markarkian's Chain. At the southwestern end of the chain are two prominent elliptical galaxies, M84 (at the far southwestwern tip of the line) and M86. Following the chain eastward and northward, M86 is followed by a pair of galaxies collectively known as the Eyes Galaxies. Imagery provided by Aladin sky atlas
The arrangement of galaxies within the cluster is not random; rather they are organised into smaller groupings of which the most prominent are designated Virgo A (organised around the Virgo Agalaxy) and Virgo B (around M49). One particularly clear feature of the cluster is a string of galaxies near its centre known as Markarian's Chain, running across the border between Virgo and Coma Berenices.
