When a star in the nearby galaxy NGC 2146 exploded in late 2024, it barely registered by supernova standards. The blast, ...

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

A distant supernova, SN 2025mkn, became visible from nine billion light years away after a galaxy’s gravity bent and brightened its light, helping scientists study it in detail.

NASA's Imaging X-ray Polarimetry Explorer reveals the expansion and shock patterns within RCW 86, a supernova observed by ...

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

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.

Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical ...

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

A supernova is one of the most powerful events that can happen in the Universe - we are talking, after all, about a star exploding – and because of that, they have always been actively researched by ...

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 ...

Researchers identified a "forbidden range" of black-hole masses more than 45 times the Sun's mass, where stellar-origin black holes are rare. The gap aligns with models in which such stars explode via ...
