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

Scientists discover a star, HD 254577, that survived a supernova and is now racing through space, revealing how the explosion ...

"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 ...

Few spectacles in space are as phenomenal as supernovae, but a "superkilonova" may give them a run for their money. This type of cosmic outburst is thought to arise when a supernova cascades into a ...

A strange flash in a distant galaxy first looked like a familiar kind of stellar wreckage, the radioactive afterglow of colliding neutron stars known as a kilonova. Then it brightened again, shifted ...

After detecting a strange combination of signals in the summer of 2025, astronomers believe they may have captured the first evidence of a unique phenomenon previously theorized, but never observed: a ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

Astronomers have spotted a jaw-dropping collision between two neutron stars – and it may have produced gold and platinum. The discovery in a tiny, faraway galaxy is the first time this has been seen ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...
