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

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 Type II supernova explosions.

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 ...

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

Some of the most spectacular images ever captured by the Hubble Space Telescope reveal the violent remains of exploding stars. These supernova remnants include glowing clouds of gas, rapidly expanding ...

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.
