The center of this composite image shows four large galaxies that are colliding and will ultimately merge. This collision is occurring in a giant cluster of galaxies called CL0958+4702. Infrared data from the Spitzer Space Telescope are shown in red, visible light data from the WIYN telescope are green, and X-rays from the Chandra X-ray Observatory appear in blue. The Chandra data show hot hydrogen gas at temperatures of a few million degrees and this gives astronomers information on how much the cluster weighs.
