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

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 ...

Scientists believe that the extreme luminosity of the supernova stems from a magnetar at its center.

Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football ...

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

WASHINGTON — A supernova — the explosion marking the end of a massive star's life — is one of the brightest cosmic events, usually about a billion times more luminous than the sun. But some — a small ...

WASHINGTON — A supernova, the explosive death of a star, is always violent, blasting material into space while typically leaving behind a compact stellar remnant like a neutron star or black hole. But ...

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 ...
