Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

A supernova – the explosive death of a star – is always violent, blasting material into space while typically leaving behind ...

A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that exploded millions of years ago. The star, which was in a nearby galaxy, exploded ...

"For the most part, massive stars make black holes. The more massive the star, the heavier the black hole," Fishbach said, until stars reach a certain mass threshold beyond which the physics of their ...

An Australian-led study published in Nature found evidence of rare exploding stars called pair-instability supernovae, revealing a “forbidden gap” in black hole masses and offering new insights into h ...
