A new analysis from NASA using the Hubble Space Telescope shows that the Crab Nebula, the remnant of a supernova recorded in 1054, is still rapidly expanding, offering rare, direct evidence that the ...

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 ...

A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that exploded millions of years ago. The star, which was in a nearby galaxy, exploded ...

The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

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 ...

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 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 ...

Astronomers have identified the first clear evidence of a magnetar forming during a superluminous supernova, offering new insight into some of the brightest explosions in the universe.

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 ...
