Cosmic rays, high‐energy particles from extraterrestrial sources, continuously bombard the Earth, providing a natural probe of astrophysical processes. When these particles interact with the ...

The study of cosmic rays, high-energy particles originating from extraterrestrial sources, has significantly progressed with the advent of both ground-based and space-borne detection techniques.

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...

Mars, Europa and Enceladus are the three most promising locations in the solar system to search for life living off cosmic rays. When you purchase through links on our site, we may earn an affiliate ...
