Perseus cluster

March 31, 2003
Atlas Image mosaic, covering 15.0´ × 29.9´ on the sky, of Abell 426, better known as the Perseus Cluster, a nearby rich galaxy cluster. The cluster is notable with its prominent grouping of bright galaxies near the core and an exceptionally strong deficiency of spiral galaxies. The cluster is dominated by NGC 1275, the strong radio source Perseus A, ther bright galaxy seen near the center of the 2MASS image mosaic; the bizarre galaxy has an active nucleus, with bright, extended radio lobes, and evidence that the galaxy is the remnant of a recent merger. 1999 Nov 17-23
