Gamma Ray Bursts are the brightest things to happen to the Universe since its beginning -- extraordinarily intense electromagnetic events releasing more energy per second than the sun does in a billion years, and basically an excuse for astronomers to use every awesome adjective they know. GRBs are an incredible demonstration of just how big a universe is: they're extremely rare, only a few per galaxy per million years, and we see about one a day. They're so interesting NASA launched a satellite just for them, the Swift Gamma-Ray Burst Mission -- a mission so advanced that "Swift" isn't even an acronym. They just liked the word.
