Brighter than an Exploding Star, It's a Hypernova! (nasa.gov)

In a galaxy not so far away - only 25 million light-years - astronomers have found what looks like are the remnants of strange celestial explosions called hypernovae. "Hypernovae are possibly the most powerful explosions in our Universe since the Big Bang," said Q. Daniel Wang, an astrophysicist at Northwestern University. Such explosions are more powerful than supernovae, the spectacular death gasps of stars some 5-10 times more massive than our Sun. In fact, hypernovae may produce some 100 times more energy than supernovae. But what are these explosions and what causes them? Astronomers are not sure at this point. It is hoped that the discovery of these two suspected hypernova remnants, called MF83 and NGC5471B, located in the nearby spiral galaxy M101 will allow astrophysicists to infer their true nature.
