Astronomers used the Hubble Space Telescope to measure the expanding Crab Nebula. New images compared with older ones show ...

The organic molecules were found within dense cocoons of gas surrounding newborn stars.

A supernova remnant is supposed to be a rough neighborhood for a newborn star. Shock waves rip through space at thousands of ...

Astronomers have made a surprising discovery inside the remains of a giant star that exploded about 1,600 years ago. They ...

A long time ago, in a galaxy far, far away, a massive star collapsed, triggering a supernova explosion so bright it could be ...

For the first time, astronomers have discovered stellar cocoons rich in complex organic molecules within a supernova remnant.

Astronomers have captured the first radio waves ever detected from a rare class of exploding star, a discovery that has given them an unprecedented look into the final years of a massive star before ...

Astronomers using NASA’s Chandra X-ray Observatory to observe galaxy Messier 83 (M83) spotted the unexpected explosive aftermath of a supernova. Typically, the aftermath of a stellar explosion is a ...

When some stars die, they do not do so alone, potentially solving a long-standing mystery around a particular class of cosmic ...

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 ...

A strange "chirping" signal from a distant supernova has revealed the birth of a magnetar, confirming that these incredibly magnetic neutron stars can power the universe's brightest stellar explosions ...

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 ...
