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 ...

Ultraheavy particle clue: Penn State-led research suggests some ultrahigh-energy cosmic rays are made of nuclei heavier than iron, altering theories on their origins. Record-breaking events: The 2021 ...

Tens of kilometers above Earth's surface, high-energy particles from outer space constantly strike the atmosphere, creating showers of energetic secondary particles that rain down from the sky.

Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help explain where these particles come from. Using the DAMPE space telescope, ...
