Optical proof of a tiny companion orbiting supergiant star Betelgeuse is hard to come by. Hubble just spotted new evidence.

For decades, astronomers have searched the skies for a missing population of doomed stars — the massive red supergiants that theory predicts should end their lives in powerful stellar explosions, but ...

Astronomers using the James Webb Space Telescope (JWST) have achieved a remarkable first: capturing a detailed view of a red supergiant star just before it exploded as a supernova. The star, located ...

Top Videos Using NASA’s James Webb Space Telescope (JWST), an international team identified a supernova’s source star, or progenitor, for the first time. The observations - combined with archival ...

The main image at left shows a combined Webb and Hubble view of spiral galaxy NGC 1637, with the region of interest in the top right. The remaining three panels show a detailed view of a red ...

PHOENIX — Like a motorboat doing doughnuts in a lake, Betelgeuse’s companion star leaves a wake in the giant star’s atmosphere. Signs of the smaller star’s trail around the red supergiant are the best ...

What can an exploding star in a distant galaxy teach scientists about red supergiants? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of ...

Astronomers say they've captured the clearest look yet of a star on the brink of supernova. An international team used NASA’s James Webb Space Telescope to backtrack and find the original star that ...
