By analyzing data from NASA's Chandra X-ray Observatory, Dutch astronomers have investigated a young, oxygen-rich supernova ...

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

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

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

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

M83 is located about 15 million light-years away from Earth and is forming stars at a high rate. Using 14 years of Chandra data of the galaxy (2000 to 2014), the team caught some surprising variations ...

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

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 ...

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.

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 ...
