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

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

A star exploded roughly 260 light-years from Sagittarius A*, the supermassive black hole at the center of the Milky Way, and ...

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 ...

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.

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. For decades, astronomers and stargazers have been waiting ...

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

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

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 ...

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 ...
