SUMMARY: Three of the Universe's largest explosions: gamma-ray bursts, X-ray flashes, and supernovae could actually come from the same event - the collapse of a supermassive star. An astronomer from Caltech has found that the different kinds of explosions seem to contain the same amount of energy, they're just divided up differently between low and high-energy jets. NASA is going to launch a new gamma-ray detecting spacecraft, called SWIFT, which should be able to detect 100 gamma-ray busts a year. This should give scientists new targets to study.
