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 ...
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 ...
The highest-energy sunlight is too bright. Astronomers have detected gamma rays coming from the sun that are more energetic than any we have seen before, and there are more of them than any of our ...
A team of astronomers have observed an explosion in the universe unlike any ever witnessed before. The gamma-ray bursts from outside the Milky Way galaxy repeated several times over the course of a ...
