Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

A never-before-seen 'chirp' in the light of an exploding star has revealed new clues about the engine powering some of the brightest supernovae in the Universe.

About a billion light-years away, an extraordinary stellar explosion lit up in the night sky. The blast, detected December 12, 2024, was some 30 times the brightness of a typical supernova, putting it ...

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

Add Yahoo as a preferred source to see more of our stories on Google. Artist's conception of a magnetar surrounded by an accretion disk exhibiting Lense-Thirring precession, in this handout image ...

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 ...

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

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

Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed ...

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.

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 ...
