Arp 147, Interacting Galaxies, Composite


This composite image of Arp 147 shows Chandra X-ray data in pink, Hubble optical data in red, green and blue, ultraviolet GALEX data in green and infrared Spitzer data in red. Arp 147, is a pair of interacting galaxies located about 430 million light years from Earth. Arp 147 contains the remnant of a spiral galaxy that collided with the elliptical galaxy. This collision has produced an expanding wave of star formation containing an abundance of massive young stars. These stars race through their evolution in a few million years or less and explode as supernovas, leaving behind neutron stars and black holes. A fraction of the neutron stars and black holes will have companion stars, and may become bright X-ray sources as they pull in matter from their companions. The nine X-ray sources scattered around the ring in Arp 147 are so bright that they must be black holes, with masses that are likely ten to twenty times that of the Sun. Release date February 9, 2011.
