Using observations from NASA’s Chandra X-ray Observatory, researchers have obtained the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded. This discovery may help astronomers understand why some supernovas are much more powerful than others.

On Nov. 3, 2010, a supernova was discovered in the galaxy UGC 5189A, located about 160 million light years away. Using data from the All Sky Automated Survey telescope in Hawaii taken earlier, astronomers determined this supernova exploded in early October 2010.

This composite image of UGC 5189A shows X-ray data from Chandra in purple and optical data from Hubble Space Telescope in red, green and blue. SN 2010jl is the very bright X-ray source near the top of the galaxy.

This is what’s known as a supernova imposter event because it appears similar but the star hasn’t actually been destroyed.  The Eta Carinae systen is one of the closest to Earth so expect the supernova to be very bright when it does happen.  But since we’re talking about events in a galactic time frame, you probably won’t be alive to see it.
