V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

Betelgeuse, 650 light years away, may be nearing the end of its fuel, meaning its supernova could light Earth’s skies as bright as the full moon.

In a new study, a team of astronomers report that they have captured the most detailed glimpse yet of a red supergiant before it exploded. Using JWST 's powerful infrared vision, the researchers ...

Astronomers observed the fading light of supernova SN 2025kg, which followed the fast X-ray transient (FXT) named EP 250108a.

The James Webb Space Telescope (JWST) has revealed a hidden "doomed" star that could help solve a giant astrophysical mystery. The star is a massive red supergiant, which JWST snapped just before the ...

The first double-burst supernova ever observed, SNR 0509, is a historic discovery that reveals how white dwarfs explode in the cosmos.

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...
