Observations with Chandra have revealed a giant cloud of superheated gas in a galaxy about 60 million light-years from Earth. Because this gas is about 6 million degrees, it only glows in X-ray light. A collision between a dwarf galaxy and a much larger galaxy called NGC 1232 is the likely cause of this gas cloud. A new composite of X-rays (purple) from Chandra and optical data (blue and white) shows the scene of the collision. // X-ray: NASA/CXC/Huntingdon Inst. for X-ray Astronomy/G.Garmire, Optical: ESO/VLT
