cosmic ray
Extraterrestrial radiation projectile
Cosmic rays are high-energy particles that travel through space and strike Earth's atmosphere.
Despite the name, they're not rays but mostly protons and atomic nuclei, originating from the sun, distant supernovae, and other cosmic sources.
When they collide with atmospheric molecules, they produce showers of secondary particles.
Cosmic rays pose radiation risks for astronauts and can affect electronics at high altitudes.
