Astronomers have spotted signs that Betelgeuse, the closest supergiant star to Earth, could be about to explode as a ...

Do we live in a supernova graveyard? A team of researchers proposes that 10 million years ago two giant neutron stars crashed ...

Deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in ...

A nearby cosmic ticking time bomb has been found! Just 150 light years away, a pair of white dwarf stars are on a death ...

We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and a little bit ...

Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will ...

"Our project was to model the propagation of cosmic rays from supernova sources to see their potential impacts on life on Earth," Nojiri explained. One particular supernova caught the attention of ...

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

Plutonium discovered at the bottom of the ocean was found to be refuse from a kilonova that exploded close to Earth 10 million years ago. Kilonovas occur when binary neutron stars spiral closer and ...

"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 ...

Thankfully, there are no such systems within 150 light-years of Earth. But there's this whole other kind of supernova, the Type 1a. These have a completely different mechanism for going boom.
