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.

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

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 ...

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.

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 ...

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 ...

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

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 ...

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.

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 ...
