Summary[edit]
| Description |
English: Gamma-ray bursts are the most powerful explosions known in the Universe, and most originate in distant galaxies. A large percentage of bursts likely arise from the explosion of stars over 15 times more massive than our Sun. Scientists say burst from a nearby star could cause severe damage to the Earth’s protective ozone layer. In this artists conception we see the gamma rays hitting the Earth's atmosphere. (The expanding shell is pictured as blue, but gamma rays are actually invisible.) |
