On 7th May 2007, NASA released this video animation of the brightest stellar explosion ever recorded, SN2006gy. Scientists at NASA's Chandra X-ray Observatory and ground-based optical telescopes believe this could be a new type of supernova, a type common in the early universe.
Nathan Smith of the University of California at Berkeley said "This was a truly monstrous explosion, a hundred times more energetic than a typical supernova. That means the star that exploded might have been as massive as a star can get, about 150 times that of our sun."
