For the first time, astronomers have captured the breathtaking moment of a supernova explosion. This cosmic event reveals the ...

Scientists using the Chandra X-ray telescope have uncovered new details about the famous supernova remnant Cassiopeia A.

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 NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they ...

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

NASA scientists have identified what may be the first known pair of supernova remnants produced by stars that once orbited ...

A star appears to have exploded near the centre of our galaxy at least 1,700 years ago. The light from that event is long ...

NASA's Chandra X-ray spacecraft has detected the supernova wreckage of a dead star that erupted 1,700 years ago and ejected debris at 2 million miles per hour.

A new AI-powered framework could transform how astronomers measure the expansion of the Universe. By analyzing images of Type ...

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 ...

Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice ...
