“New X-ray data from NASA’s Chandra X-ray Observatory added to an image previously captured by the Hubble Space Telescope created this amazing composite image of two black holes on the verge of colliding.

The two supermassive black holes, which show up as two points of light in the center of the galaxy NGC 6240, are only 3,000 light-years apart. Astronomers think the two will eventually combine into a single, larger black hole.” (Wired)
