Black Hole Cannibal

Deep in the dark heart of the galaxy NGC 3393, two monsters are eating each other in an epic clash of the titans.

In August scientists with NASA's Chandra X-ray Observatory released this composite image of the spiral galaxy that shows not one but two supermassive black holes in its middle, separated by just 490 light-years.

Astronomers think NGC 3393 must have consumed a less massive galaxy that had a black hole of its own, and the two supermassive beasts are now battling it out until just one central black hole remains. (Also see "Black Hole Caught Eating a Star, Gamma-Ray Flash Hints.")
