摘要

Gamma-ray bursts (GRBS) are one of the most mysterious and controversial things astronomers can see. Mysterious, because until a few months ago, there was no consensus about what caused them. Controversial, because even though there is now agreement about the underlying cause―supernovas―there is an argument about how such stellar explosions actually generate gamma rays. These rays are an energetic form of electromagnetic radiation. (More familiar forms of this radiation include radio, light and x-rays.) About once a day a spot in the sky lights up with a burst of them so intense that it is billions of times more powerful than anything else in the universe.
