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 ...
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 ...
LSU researchers helped uncover what may be the first clear detection of gamma rays from a superluminous supernova, using data ...
A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser.
In 2025, astronomers detected a blast from space. Now they’re uncovering the strange processes behind the exceptional ...
Above the cloud tops, thunderstorms throb with a complex, frenetic light show of high-energy radiation. A view from a retrofitted spy plane soaring at 20 kilometers up revealed storms glowing and ...
NASA’s Fermi Gamma-Ray Space Telescope has provided what may be the first clear detection of gamma rays from a superluminous ...
