London, UK (SPX) Mar 13, 2025

A recent study suggests that at least two of Earth's mass extinctions may have been triggered by the powerful effects of nearby supernova explosions. Researchers at Keele University propose that these cosmic blasts-marking the end of massive stars-could have stripped Earth's atmosphere of ozone, induced acid rain, and exposed life to harmful ultraviolet radiation from the Sun.
