Virgo Cluster

The nearest large galaxy cluster, ~54 million light-years away in the constellation Virgo. About 1300 known member galaxies, dominated by the giant elliptical M87 (which hosts the supermassive black hole imaged by the Event Horizon Telescope in 2019). Sits at the gravitational center of the Virgo Supercluster, the local supercluster that contains the Milky Way.
