This sequence shows different views of the galaxy cluster known as Abell 2125. The first image is Chandra's X-ray view where red, green, and blue represent low, medium, and high-energy X-rays respectively. The view then dissolves into an image of Abell 2125's core where red is optical emission, and green and blue reveal the X-ray structure. Finally, the sequence zooms into a close-up of C153, a galaxy that's being ripped apart as it travels through the Abell 2125 cluster. Here, the red color represents visible light as seen by Hubble, and green and blue once again show the X-ray emission observed by Chandra.
