A new study has found that a 1-in-10,000-year radiation burst from space was so powerful that it shook the Earth's upper atmosphere last year. The Earth's atmosphere, whose ionisation stability is critical to the evolution and survival of life, is subjected to the effects of cosmic explosions that produce high-energy gamma-ray bursts (GRB).

Gamma-ray bursts are so powerful they could vaporize the Earth from 200 light-years away. Gamma-ray bursts are thought to occur when a massive star runs out of nuclear fuel and its core collapses. Now, NASA has announced that on 9 October 2022, satellites detected an extremely bright gamma-ray signal that suddenly exploded from the constellation of Sagitta; it lasted hundreds of seconds.
