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

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

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.

The star, WOH G64, lies inside the Large Magellanic Cloud, about 163,000 light-years from Earth. It is enormous, roughly 1,540 times ...

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.

For the very first time, astronomers have captured a radio signal emitted by a very specific type of stellar explosion. This unprecedented observation offers us a glimpse into the final moments of ...

Maybe music artist Moby was right, and “we are all made of stars.” New research suggests the calcium in our teeth and bones came from star explosions. Researchers from Northwestern University looked ...

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.

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 ...
