NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, ...

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 ...

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

The powerful gravity of a galaxy embedded in a massive cluster of galaxies in this Hubble Space Telescope photo is producing multiple images of a single distant supernova far behind it. Both the ...

Astronomers say they've captured the clearest look yet of a star on the brink of supernova. An international team used NASA’s James Webb Space Telescope to backtrack and find the original 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 extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.

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

For decades, astronomers have searched the skies for a missing population of doomed stars — the massive red supergiants that theory predicts should end their lives in powerful stellar explosions, but ...

Some of the most spectacular images ever captured by the Hubble Space Telescope reveal the violent remains of exploding stars. These supernova remnants include glowing clouds of gas, rapidly expanding ...

An international research team led by Chinese scientists has discovered new evidence about Type II-P supernovae, suggesting that some of these stellar explosions may originate from merged binary stars ...

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