The light from an exploding star trillions of miles was recently observed by astronomers. The huge star that exploded was estimated to be 150 times as massive as the Sun.
A gargantuan explosion ripped apart a star perhaps 150 times more massive than our sun in a relatively nearby galaxy in the most powerful and brightest supernova ever observed, astronomers said on Monday.
And there is one such star in our own Milky Way galaxy that appears to be on the brink of dying in just such a supernova.
The exploding star's dramatic death may have come in a rare type of supernova reserved for "freakishly massive" stars that astronomers had speculated about but never previously witnessed.
The supernova, designated as SN 2006gy, occurred 240 million light years away in a galaxy called NGC 1260, and was studied using observations from NASA's orbiting Chandra X-ray Observatory as well as earthbound optical telescopes.
It was the brightest supernova ever observed by Chanda. This video shows how Chandra observes an exploding star.
