One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't ...

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

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 say one of the universe’s largest stars has dramatically changed since 2014, possibly entering a rare final phase that could end in a spectacular supernova explosion.

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

It's never too late to solve a cold case. A new paper from Syracuse University researchers proposes an explanation for both a mysterious stellar object discovered in the year 2013 and an astronomical ...

Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...

This artist's animation shows a hypothe sized event known as a superkilonova . Initially, a massive star explodes in a supernova, which generates elements like carbon and iron. In the aftermath, two ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
