A dying massive star does not go quietly. Its core collapses, matter crashes inward, neutrinos pour out in staggering numbers ...
Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic ...
Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm. After detecting ripples in space-time, scientists spotted a fast-fading ...
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 ...
