Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

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 ...

WASHINGTON, Nov 12 (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.

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 ...

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 ...
