A supernova – the explosive death of a star – is always violent, blasting material into space while typically leaving behind a compact stellar remnant like a neutron star or black hole. But some ...

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

The ‘guest star’ of 185 AD has been one of astronomy's most unresolved cases for over 1800 years. Ancient Chinese chroniclers recorded a mysterious li.

"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 ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...
