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

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

The study of cosmic rays and heliospheric physics bridges our understanding of high‐energy particles from distant astrophysical sources and the dynamic environment shaped by the solar wind and ...

A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of 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, ...
