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

Exploding stars in near-solar space may have triggered at least two mass extinction events in Earth’s history. A new study ...

Some of the most massive and influential stars in the universe are OB stars. These blue giants, many times more massive than ...

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

"If a massive star were to explode as a supernova close to the Earth, the results would be devastating for life on Earth," said Nick Wright, an astrophysicist at Keele University in the United Kingdom ...

The late Devonian period was characterized by many environmental changes, although it’s not clear what caused an estimated 70 to 80 percent drop in species numbers. Some scientists don’t consider this ...

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, ...

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 ...
