As­tro­no­mers have detected the brightest stellar explosion/supernova (SN2006gy) ever recorded, a new breed of supernova that may also oc­cur be­fore long in our own ga­l­axy—what one re­search­er said would be his­to­ry’s most awe­some star show, according to  observations by NASA’s Chandra X-ray Observatory and ground-based optical telescopes.

“This was a truly monstrous explosion, a hundred times more energetic than a typical supernova,” said Nathan Smith of the University of California, Berkeley, who led a team of astronomers from California and the University of Texas in Austin. “That means the star that exploded might have been as massive as a star can get, about 150 times that of our sun. We’ve never seen that before.”
