The Perseus Cluster is part of the vast Pisces-Perseus Supercluster.
Rich galaxy clusters like the Perseus Cluster are analogous to globular star clusters.
They are dense, roughly spherical balls of galaxies in complex orbits around the center.
The concentration of galaxies in the Perseus Cluster is one of the highest known. Abell 426 is a diffuse and irregular cluster of galaxies, containing about 500 members and located about 250 million light-years away, that is dominated by and centered on the Seyfert galaxy NGC 1275 associated with the radio source Perseus A. The mass of cluster has been estimated at 200 trillion solar masses More informations are available at the wikipedia.org website |
