New research published by Michigan State University astrophysicists could help scientists answer a century-old question: Where did galactic cosmic rays come from? Cosmic rays—high-energy particles ...

Every second, without you knowing it, thousands of billions of invisible particles pass through your body. These cosmic objects travel across the Universe from distant sources, moving at prodigious ...

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

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 ...
