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

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 Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that ...

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 ...

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

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

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

Supernovae, these gigantic stellar explosions, release a phenomenal amount of energy. This energy travels through space, capable of reaching planets located thousands of light-years away. Scientists ...

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

NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, revealing a red supergiant star before explosion.

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.
