Watch the moment a star explodes in a supernova — something scientists have never directly witnessed like this before. The footage captures the early stages of the explosion, offering a rare glimpse ...

Astronomers have turned a famous star explosion into a 25‑year time‑lapse, using a NASA telescope to watch the superheated gas race through space and slam into its surroundings. The new study using ...

A supernova witnessed nearly 2,000 years ago is back in focus as NASA’s powerful X-ray telescope uncovers a hidden cosmic ...

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

XRISM’s high-precision X-ray data revealed unusually strong signatures of chlorine and potassium inside the Cassiopeia A supernova remnant. These levels are far higher than theoretical models ...
