How do gamma ray bursts happen
Web“Based on our simulations, a gamma-ray burst as energetic and as close as this one is likely to occur less than once every 1,000 years, so this really is a remarkable event that we’re unlikely to see again in our lifetimes,” said Maia Williams. 08 Apr 2024 12:05:00 WebThe gamma radiation from a burst within a few kiloparsecs would quickly deplete much of the Earth's protective ozone layer, allowing an increase in solar UVB radiation reaching the surface. This radiation is harmful to life, damaging DNA and causing sunburn. In addition, NO2 produced in the atmosphere would cause a decrease in visible sunlight ...
