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

We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties ...

They then performed supernova simulations to determine how current theories of stellar evolution could explain a neutron star with such a low mass.

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.

Water may have formed less than 200 million years after the Big Bang, suggesting some conditions for life existed far earlier than previously thought.

The discovery delays the timeline for planet formation. The building blocks of life appeared earlier, scientists say.
