The Van Allen belts aren't a problem just for space exploration. They can damage satellites, too, and we're putting up a lot of satellites these days.

Oh, that Van Allen Belt—online crackpots love to use Earth’s belt of radiation to bolster their Moon landing conspiracies, suggesting it could be too. Skip to content Gizmodo. Search .

Giant donut-shaped swaths of magnetically trapped, highly energetic charged particles surround Earth. James Van Allen, a physicist at the University of Iowa, discovered these radiation belts in ...

Two giant swaths of radiation, known as the Van Allen Belts, surrounding Earth were discovered in 1958. In 2012, observations from the Van Allen Probes showed that a third belt can sometimes appear.

NASA's new Van Allen Probes have revealed how quickly the radiation belts around Earth change, and how charged particles there vary in time, energy and spatial distribution.

This third Van Allen belt lasted only a few weeks before it vanished, and its cause remained inexplicable. Mann is co-investigator on the NASA Van Allen Probes mission.

Los Alamos, N.M., March 20, 2017--The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA's ...

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 ...

It was named the Van Allen radiation belt, after its discoverer, U.S. space scientist James Van Allen. But not much was known about it until NASA launched two probes in 2012.

When NASA scientists launched twin spacecraft to probe the Van Allen radiation belts last summer, they were expecting to study two rings of high-energy particles circling Earth. Instead they found ...
