WASHINGTON (Reuters) -The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks as it unfolds has remained mysterious. Scientists ...

Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar explosions are known, that ...

Astronomers have, for the first time, recorded the moment a star’s explosion broke through its surface. The nearby supernova, SN 2024ggi, revealed a surprisingly olive-shaped blast when studied with ...

Scientists have identified a never-before-seen supernova, SN2021yfj, which exploded after losing nearly all of its outer layers. Instead of light elements, it revealed silicon and sulfur from deep ...

In an unprecedented discovery, astronomers have observed a new type of supernova that seems to defy the very principles of stellar evolution that have been held for decades. The supernova, named ...

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...
