Galactic Cosmic Rays

Galactic Cosmic Rays (GCRs) are high-energy particles, mainly protons and atomic nuclei, that originate from outside our solar system, often from supernova explosions or other cosmic events. As they travel through space, they can interact with magnetic fields and solar winds. GCRs are significant in space physics because they can pose health risks to astronauts and affect satellite operations due to their immense energy. Understanding GCRs helps scientists better comprehend cosmic processes and protect space missions from their effects.
