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 ...

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

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

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 ...

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

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National ...

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.

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 ...
