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

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 ...

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos. Researchers have now been able to study some of a supernova's progression by ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a superkilonova.

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.

This artist’s impression shows a star going supernova. About 22 million light-years away the supernova, SN 2024ggi, exploded in the galaxy NGC 3621. Using the ESO’s Very Large Telescope, astronomers ...

One of the largest stars close enough for us to estimate its size, WOH G64, appears to have gone from red to yellow in 2013-14, indicating a temperature rise of about 1,000°C (1,800°F). Last year it ...

WASHINGTON (Reuters) -Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar ...

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 ...
