Scientists from Keele University have found strong evidence that some of Earth’s past mass extinctions could have been caused by nearby supernova explosions—massive star explosions in the Milky Way.

For this reason black holes are invisible to the eye, as lightless as the empty, dark space surrounding them. Scientists know they exist not because they can see an actual hole, b ...

"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 ...

Why Do Black Holes Form? Black holes form when a huge amount of matter is squeezed into a very small space. Cram enough ...

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, ...

A supernova is a cataclysmic stellar death that leaves behind a black hole or neutron star. It is the biggest, brightest, and most violent type of explosion scientists have observed in the universe.

Exploding stars known as supernovas may have sparked mass extinctions that wiped out up to 85% of animals on Earth.
