space radiation
Extraterrestrial particle hazard
Space radiation is the high-energy particles and electromagnetic radiation that permeate outer space, originating from the sun, distant stars, and galaxies.
Unlike the radiation we encounter on Earth, which is largely filtered by the atmosphere and magnetic field, space radiation poses significant hazards to astronauts and spacecraft electronics: NASA studies space radiation to protect crews on long-duration missions.
The term encompasses solar particle events, galactic cosmic rays, and radiation trapped in planetary magnetic fields.
