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

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

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.

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 ...

Betelgeuse is one of the closest stars to Earth, at a distance of only 650 light-years away. This makes Betelgeuse a fan-favorite with professional and amateur astronomers alike. Betelgeuse is a red ...

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, ...

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 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 ...
