For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its ...

Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.

Scientists from the Telescope Array Collaboration have detected an ultrahigh-energy cosmic ray, a discovery that’s challenging our current understanding of exotic cosmic phenomena and their origins.

Planning a trip to Mars? Take plenty of shielding. According to sensors on NASA’s ACE (Advanced Composition Explorer) spacecraft, galactic cosmic rays have just hit a Space Age high. “In 2009, cosmic ...
