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

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.

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 ...

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

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

An international team of astronomers has carried out photometric and spectroscopic observations of SN 2024abvb—a recently ...

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

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.
