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

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

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, ...

During the Devonian geological era ... along with armored fish and other marine species. A cataclysmic shift at the end of the Ordovician led to the disappearance of about 85% of species at ...

Thrips are tiny insects—their sizes range between 0.5mm and 15mm in length and many are shorter than 5mm. But the damage they ...

Five 'mass extinctions' have decimated our planet since it was formed - now scientists claim the answers to two could be written in the stars.

The late Devonian extinction eliminated 70% of species, reshaping marine ecosystems. Scientists have long suspected that damage to the ozone layer played a role in these ice ages. Now ...
