The explosion of a massive star leads to the expulsion of its envelope, and this “ejecta” expands outward with time and interacts with the medium surrounding the star at the time of its death. The ...

Observations by two of the world’s largest telescopes provide strong evidence that a peculiar type of exploding star may be the origin of elusive gamma-ray bursts that have puzzled scientists for more ...

Astronomers have glimpsed the inner structure of a dying star in a rare kind of cosmic explosion called an “extremely stripped supernova”. In a paper published today in Nature, Steve Schulze of ...

Astronomers don’t often get to witness a gigantic star getting undressed. But that is exactly what they witnessed with SN2021yfj, a 2.2-billion-light-year-away stellar explosion whose naked look has ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new Type II supernova. The ...

New observations of a recently exploded star are confirming supercomputer model predictions made at Caltech that the deaths of stellar giants are lopsided affairs in which debris and the stars’ cores ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...
