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

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

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 ...

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

For the first time, we have a front-row seat to one of the most violent events in the universe: a supernova. But there’s a ...

The star, WOH G64, lies inside the Large Magellanic Cloud, about 163,000 light-years from Earth. It is enormous, roughly ...

NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, revealing a red supergiant star before explosion.

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

A deep-space photo of the Jellyfish Nebula in Gemini shows a brain-like structure, capturing the supernova remnant IC 443 and surrounding interstellar gas and stars.

A rare gravitationally lensed supernova called SN 2025wny appears in five separate images due to the gravity of two ...

An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.
