GREENBELT, Md., Aug. 12 (UPI) -- U.S. astronomers have released a dramatic image of two galaxies heading for a collision about 450 million light years from Earth.
The image of the galaxies, in the constellation Bootes in the Northern Hemisphere, is a composition of optical data from the Hubble Space Telescope and X-ray data from the Chandra X-ray Observatory satellite, a NASA release said.
