Colliding galaxies, space telescope image. Composite image obtained by combining data from NASA's Chandra X-ray Observatory (purple) with data from the Hubble Space Telescope (HST, red, green, blue), showing VV 340, a pair of galaxies colliding about 450 million light years from Earth. The two galaxies are in the early stage of an interaction that will eventually lead to them merging in millions of years time. The Chandra data shows that the northern galaxy contains a rapidly growing supermassive black hole that is heavily obscured by dust and gas.
