BEIJING -- For decades, scientists have been trying to solve a mystery: Where do high-energy cosmic rays come from? These ...

There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed.

Scientists have detected a universal energy threshold across all cosmic rays, and it may rewrite a century of astrophysics.

Detection by Askaryan Radio Array holds promise for future research into sources, nature of cosmic rays and neutrinos ...

New cosmic ray theory: Researchers suggest ultraheavy atomic nuclei may explain the origins of the highest-energy cosmic rays ever detected. Why it matters: Ultraheavy nuclei could survive longer ...

Cosmic rays (CRs) are energetic particles traveling through space at speeds close to that of light. They consist of atomic nuclei, electrons, positrons, high-energy gamma rays, and neutrinos, and are ...

A long-standing cosmic mystery is beginning to yield new clues as researchers uncover a strikingly consistent pattern in the ...

New cosmic ray clue: Scientists propose that ultraheavy nuclei could explain how the most energetic cosmic rays reach Earth. Survival advantage: Ultraheavy nuclei lose energy more slowly in space, ...
