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

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

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

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 ...

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

Among these are the late Devonian extinction, 372 million years ago, and the late Ordovician extinctions, around 445 million years ago. Somewhere up to 75% or 85% of animal species, mostly marine ...

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

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 ...

Life reconstruction of the non-marine component of the Waterloo Farm biota. Hyneria udlezinye is shown together with the tetrapods Umzantsia amazana and Tutusius umlambo, the placoderms ...

In 2007, a large donation by David Kemp added considerably to the UK Eocene taxa represented. Collected by Harry Toombs in the 1960s from the Late Devonian Gogo Formation of western Australia. Fossil ...
