NGC 1275 is the type SO galaxy at the center of this image of a portion of the
Arp 428 galaxy cluster.
It is the dominant member of the Perseus
Cluster of Galaxies and a strong radio source, therefore named Perseus A, and 3C
84 from its entry in the 3rd Cambridge Catalogue of Radio Sources. It is also a
strong X-ray source. Its nucleus shows emission lines and is of Seyfert type 1 -
this galaxy was in Carl Seyfert's original list of galaxies with peculiar
emission lines in their nucleus, now called Seyfert galaxies. Filaments of
gaseous material are moving explosively outward at 1500 miles per second. (SEDS)
Redshift distance is 242 Mly.
