Asrtronomers managed to pinpoint which star in the NGC 1637 galaxy turned into a supernova 40 million years ago, they used the Webb telescope.

One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a ...

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos.

Betelgeuse is one of the closest stars to Earth, at a distance of only 650 light-years away. This makes Betelgeuse a fan-favorite with professional and amateur astronomers alike. Betelgeuse is a red ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to ...

A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that ...

Astronomers used Webb to find the star behind supernova 2025pht, revealing how thick dust can hide massive red supergiants.

The light from the explosion did not reach Earth till June 29, 2025, when the All-Sky Automated Survey for Supernovae detected it.

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 ...

A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...
