A research team linked nearby stellar explosions to at least one, possibly two, mass die-offs after calculating the supernova ...

Deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in ...

While the common ancestor of vertebrates with synovial joints is still a mystery, the oldest specimen with evidence of these ...

New research suggests that powerful star explosions, called supernovae, may have caused at least two mass extinctions in ...

A supernova — the explosive death of a massive star — can leave behind a black hole or neutron star. These cosmic blasts are element factories, spreading carbon, calcium, and iron across space, ...
