Roughly a century ago, scientists began to realize that some of the radiation we detect in Earth’s atmosphere is not local in origin. This eventually gave rise to the discovery of cosmic rays — ...

Proof that ultra-high-energy cosmic rays come from outside the Milky Way has been published by astrophysicists working on the Pierre Auger Observatory in Argentina. Their measurement has a statistical ...

Cosmic rays definitely have the most mysterious-sounding name in the universe, and they definitely live up to it. Even their history is intriguing. Physicists first suspected their presence more than ...
