Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

NASA’s James Webb Space Telescope has identified the red supergiant star that exploded as supernova SN 2025pht in galaxy NGC ...

NASA's Chandra X-ray Observatory releases its longest-spanning video of X-ray data yet. Credit: NASA / CXC / SAO / Pan-STARRS Astronomers have turned a famous star explosion into a 25‑year time‑lapse, ...

Astronomers using NASA’s Chandra X-ray Observatory to observe galaxy Messier 83 (M83) spotted the unexpected explosive ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

Astronomers studying the rare supernova SN 2021yfj discovered material from one of the deepest layers of a dying star, providing a rare look at its hidden interior. The finding confirms key theories ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they ...
