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

One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.

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 ...

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

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

A team of astronomers employing the James Webb Space Telescope (JWST) has discovered the most distant exploding star to be recorded spectroscopically, giving scientists a glimpse into the early days ...

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 report a supergiant star in the Andromeda Galaxy, M31-2014-DS1, collapsed directly into a black hole without a supernova, confirming predictions of failed stellar explosions.

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 catch - the shape of the explosion was not what we expected. In this video, ...

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

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