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 ...

Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant ...

LSU researchers helped uncover what may be the first clear detection of gamma rays from a superluminous supernova, using data ...

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

Through the years since it was first launched, the Hubble Space Telescope has captured stunning photographs of the Cassiopeia ...

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, ...

An international team of researchers has developed new stellar and supernova models to explain the mysterious elemental abundance patterns left by billions of supernova explosions around the Perseus ...

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 ...

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 ...
