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 ...

A burst of light in the deep sky is doing something it should not be able to do. It looks like one supernova, but it shows up ...

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.

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

WOH G64 has always been an oddball. It sits in the Large Magellanic Cloud, a small galaxy that orbits the Milky Way, and it ranks among the most extreme red supergiants known.

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

Discover how the giant star WOH G64, one of the largest known, transformed in 2014 and might be heading for a supernova.

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

You're not prepared for its size. The post Evidence Grows That One of the Largest Known Stars Is Poised to Explode in a ...
