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

M83 is located about 15 million light-years away from Earth and is forming stars at a high rate. Using 14 years of Chandra ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed ...

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.

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

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 ...

Astrophysicists measured the light for exploding stars called supernovae to arrive at the most precise limits yet for the universe’s composition – Copyright AFP ...

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 ...

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 ...
