Scientists say a supernova explosion close to Earth could be to blame for two extinction events. The post Supernova study suggests space blasts wiped out ancient life on Earth appeared first on Talker.

Exploding stars in near-solar space may have triggered at least two mass extinction events in Earth’s history. A new study led by astrophysicist Alexis Quintana from the University of Alicante suggests that supernovae—the violent deaths of massive stars—could be responsible for the Late Ordovician and Late Devonian extinction events.
