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

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

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

Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed ...

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National ...

Far beyond the Milky Way, in a nearby satellite galaxy, a giant star has been shifting in a way astronomers did not expect.

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

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.

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 ...

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. At such a critical moment in US history, we need ...

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 ...
