This supernova in galaxy UGC 5189A was discovered in late 2010. This composite image brings together data from NASA's Chandra X-ray Observatory and optical data from the Hubble Space Telescope. Astronomers say the observations from Chandra provided the first x-ray evidence of a supernova's shockwave breaking through the cocoon of gas around the star that exploded.
