Illustration of a gamma-ray burst (blue-white) hitting the Earth's atmosphere (red). Gamma ray bursts are the most powerful explosions known in the Universe. Most originate in distant galaxies arising from the explosion of stars over 15 times more massive than our Sun. Computer models indicate that a burst from a nearby star could cause severe damage to the Earth's protective ozone layer. | |
