Astronomers have discovered a superluminous supernova drawing energy from a surrounding glowing structure, challenging current understanding of extreme events.

A set of supernovae are behaving in weird ways, more than a decade’s worth of data from NASA’s Chandra X-ray Observatory ...

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

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed ...

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 ...

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 ...

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.

"Our study provides a new direction to understand the whole evolutionary history of massive stars toward the formation of black hole binaries." When you purchase through links on our site, we may earn ...

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 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 ...
