The Van Allen Belts are areas of high radiation where solar particles have been trapped and accelerated by the Earth's magnetic field. This has long been touted as evidence by conspiracy theorists ...

Relativistic electrons in the outer Van Allen belt wreak havoc with satellites in geosynchronous orbit, but how they reach such high energies has been unclear. New data identify gyro-resonant wave ...

Launched in 2012, NASA’s twin Van Allen radiation belt probes have been swinging through the hazardously charged-particle region around Earth while returning valuable scientific data that has ...
