A stellar explosion that briefly outshone its entire host galaxy may have left behind a calling card no superluminous ...

LSU researchers helped uncover what may be the first clear detection of gamma rays from a superluminous supernova, using data from NASA's Fermi Gamma-ray Space Telescope—a breakthrough that offers new ...

For more than a decade, physicists hunting dark matter in the Milky Way’s core kept circling the same clue: a faint glow of gamma rays peaking around 2 GeV, maddeningly ambiguous, never quite proving ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

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 ...

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 ...

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...

A researcher identified gamma ray emissions that appear to have originated from dark matter, but other physicists still aren’t convinced. Reading time 4 minutes Astronomers have spent nearly a century ...

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

An X8.2 class solar flare flashes in the edge of the Sun on Sept. 10, 2017. This image was captured by NASA's Solar Dynamics Observatory and shows a blend of light from the 171 and 304 angstrom ...
