In 1958, James Van Allen discovered far fewer cosmic rays than expected using a cosmic-ray detector and suggested that a belt of strong radiation may have damaged the device. The belts were therefore ...

CubeSat satellite activates after a powerful solar storm and discovers two new and mysterious radiation belts around Earth.

NASA’s Van Allen Probes mission has discovered a previously unknown third radiation belt around Earth, revealing the existence of unexpected structures and processes within these hazardous regions of ...

A ring of radiation previously unknown to science fleetingly surrounded Earth last year before being virtually annihilated by a powerful interplanetary shock wave, scientists say. NASA's twin Van ...

Earth is surrounded by a radio field caused by very low-frequency waves. This field pushes away the Van Allen Belts, a radiation swim-floaty that surrounds Earth's middle. Van Allen radiation hinders ...

Two tough, resilient, NASA spacecraft have been orbiting Earth for the past six and a half years, flying repeatedly through a hazardous zone of charged particles around our planet called the Van Allen ...

The Van Allen Belts are a pair of rings, circling the earth, made up of charged particles. Named for astronomer James Van Allen, these cosmic doughnuts were discovered early in the space age - back in ...

Our planet is nestled in the center of two immense, concentric doughnuts of powerful radiation: the Van Allen radiation belts, which harbor swarms of charged particles that are trapped by Earth’s ...
