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

Violent supernovas may have caused two of Earth’s largest mass extinctions that have never been completely explained, ...

At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts ...

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

Specifically, the findings support the hypothesis that supernovae could have triggered two of the so-called "big five" mass ...

Two of Earth’s five confirmed mass extinction events could have been caused by nearby supernova explosions stripping the ...

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

The rate of stars going supernova near Earth appears to match two mass extinctions -- 372 million years ago and 445 million ...

At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova ...
