virgo cluster

English - English

Definition of virgo cluster in English English dictionary

Closest large cluster of galaxies at a distance of about 50 million light-years in the direction of the constellation Virgo. About 200 bright galaxies and thousands of faint ones reside in the cluster. In turn, the Virgo cluster lies at the approximate centre of a larger gravitationally bound structure, called the Local Supercluster, which also includes the Local Group of galaxies, to which the Milky Way Galaxy belongs. Near the centre of the Virgo cluster is the giant elliptical galaxy M87 (or Virgo A), one of the strongest radio sources in the sky and also a powerful X-ray source. Images of M87s active galactic nucleus, obtained in 1994, revealed gas orbiting at such high speeds that astronomers believe a supermassive black hole must be present
