It’s a Dog-eat-Dog Universe and some Galaxies are wearing Milk Bone underwear

NASA, ESA and S. Farrell (University of Sydney, Australia, and University of Leicester, U.K.) The huge spiral galaxy in the image above is ESO 243-49. The circled bluish dot on it’s upper left edge, slightly off the central disk is the black hole remnant of a former dwarf galaxy which has lost most of it’s mass to the larger galaxy. What is unique about this discovery is the location of the black hole on the edge of and and not at the center of a galaxy for the reason just mentioned. I’m not sure if this is a first discovery of this type but it has all the features associated with black hole; namely a large amount of energetic blue light originating from the black hole’s accretion disk with comcomitant x-rays generated from gas and dust spiraling inward. Also noted is the presence of red light indicating possibly a number of young stars orbiting this black hole. Article appears in Feb 15th Astrophysical Journal
