Description
Colliding spiral galaxies. Composite image showing a pair of colliding spiral galaxies in a giant gas cloud located around 330 million light years from Earth. This gas cloud is located in the system called NGC 6240, which has long been known as the site of the merger of two large spiral galaxies similar in size to our own Milky Way. Each galaxy contains a supermassive black hole at its centre. The black holes are spiralling toward one another, and may eventually merge to form a larger black hole. Imaged by NASA's Chandra X-ray observatory (purple) and the Hubble Space Telescope (HST).
