Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of ...

Imagine watching a massive star that's been burning steadily for millions of years suddenly dim, fluctuate, and then vanish completely from the night sky. This isn't science fiction. It's happening ...

The first stars in the universe formed out of pristine hydrogen and helium clouds, in the first few hundred million years after the Big Bang. New James Webb Space Telescope (JWST) observations reveal ...

This popped up on my feeds. Over the last three years, a star went from fairly bright red to nothing. The analysis of the data suggests it was a direct collapse (no supernova) of a 13 solar mass star.
