Which galaxy cluster forms the heart of the Virgo Supercluster?

The Virgo Cluster forms the heart of the Virgo Supercluster.

The Virgo Cluster is a large concentration of galaxies in the constellation Virgo, roughly 54 million light-years from Earth. It is the nearest major galaxy cluster and contains approximately 1,300 known member galaxies, with estimates potentially reaching 2,000. The Local Group, including the Milky Way and Andromeda Galaxy, lies near the outskirts of the broader Virgo Supercluster.

The cluster is dominated by giant elliptical galaxies, including Messier 87, whose central supermassive black hole became famous through the Event Horizon Telescope’s 2019 image. Its immense gravity influences the motions of nearby galaxy groups, including our own, contributing to the large-scale Virgocentric flow.

The Virgo Cluster is not the same structure as the Virgo Supercluster: the cluster is a dense gravitationally bound concentration, while the supercluster is a much larger arrangement of clusters, groups, and filaments. Modern cosmic mapping places the Virgo Supercluster within the still larger Laniakea Supercluster.
