Story summary

A groundbreaking study from Keele University reveals that two significant mass extinctions—the Late Devonian and Late Ordovician—might have been sparked by supernova explosions just 65 light-years away. These cosmic events could have depleted ozone layers, exposing life to deadly radiation. Thankfully, the nearest stars poised for such explosions are now safely distant, sparing us from similar fates.
