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 for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

Betelgeuse is one of the closest stars to Earth, at a distance of only 650 light-years away. This makes Betelgeuse a fan-favorite with professional and amateur astronomers alike. Betelgeuse is a red ...

In December 2024, the ATLAS astronomical survey detected a distant flash of light. It was a supernova, the explosive death of a massive star, located far, far away, roughly a billion light-years away.

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 ...

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 ...
