A multimillion-degree gas cloud inside a spiral galaxy 60 million light years from Earth is captured in this photograph released by NASA this week. The gas cloud, shown in purple, was imaged by NASA's Chandra X-ray telescope, and the spiral galaxy in blue and white was captured by the European Southern Observatory's Very Large Telescope. Scientists believe the cloud was formed by the crash of a dwarf galaxy into a much larger galaxy called NGC-1232. It's a spectacular image, and the numbers associated with this event are stunning. The galaxy collision itself should last for 50 million years, NASA says, and the gas cloud should glow in X-rays for tens of hundreds of millions of years. Read more about the event here. NASA's Chandra X-Ray Telescope program is managed by the Marshall Space Flight Center in Huntsville. See more NASA Pictures of the Week below.
