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

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 ...

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

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

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.

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.

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

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 ...

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 ...
