the experts found that their research supported the theory that a supernova explosion was responsible for both the late Devonian and Ordovician extinction events -- two of the five known mass ...

This realization led Wright and his co-authors to connect the cosmic phenomenon with mass extinctions on Earth. Cataclysmic events have taken place five times in the past 500 million years ...

Specifically, the findings support the hypothesis that supernovae could have triggered two of the so-called "big five" mass extinctions: those at the end of the Ordovician Period, some 445 million ...
