NASA's Fermi Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of ...

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

NASA's Chandra X-ray Observatory releases its longest-spanning video of X-ray data yet. Credit: NASA / CXC / SAO / Pan-STARRS Astronomers have turned a famous star explosion into a 25‑year time‑lapse, ...

A massive star in the Andromeda Galaxy, one of the most luminous objects in its neighborhood, has quietly disappeared. Over ...

Astronomers have witnessed the birth of a rapidly spinning, highly magnetized neutron star or "magnetar" for the first time. The observation of this event, triggered by the death of a massive star, ...

NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast ...

Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...

It's never too late to solve a cold case. A new paper from Syracuse University researchers proposes an explanation for both a mysterious stellar object discovered in the year 2013 and an astronomical ...
