Ultra-high energy cosmic rays are orders of magnitude more powerful than the sun's energetic particles: They can reach up to 10 20 electron volts, whereas particles from the sun can reach up to 10 ...

Nobel laureate Prof. James (Jim) Cronin also devoted the second half of his career to studying cosmic rays. He conducted an experiment known as the Chicago Air Shower Array (CASA), which ran from 1992 ...

Observing these cosmic rays, particularly ultra-high energy cosmic rays (UHECRs), requires sophisticated detection techniques and instruments. Recent research has focused on developing and ...

Artist’s illustration of ultra-high-energy cosmic ray astronomy to clarify extremely energetic phenomena in contrast to a weaker cosmic ray that is impacted by electromagnetic fields.

Generated when high-energy particles in space strike the atmosphere above Earth, muons have been used to monitor magma movement in a volcano, detect empty cavities in the Great Pyramid of Giza in ...
