Were it exploding stars that wiped out life on earth—twice? Scientists say yes
A new study reveals that supernova explosions may have caused two mass extinctions on Earth 372 million and 445 million years ago by damaging the planet’s atmosphere and triggering climate shifts. Researchers indicate that while catastrophic supernova events pose minimal threat presently, they may have been a significant factor in Earth’s ancient history.
