This open access book serves as textbook on the physics of the radiation belts surrounding the Earth. Discovered in 1958 the famous Van Allen Radiation belts were among the first scientific discoveries of the Space Age. Throughout the following decades the belts have been under intensive ...
Recent observations by NASA’s twin Van Allen Probes show that particles in the radiation belts surrounding Earth are accelerated by a local kick of energy, helping to explain how these particles reach speeds of 99 percent the speed of light. Credit: G. Reeves/M. Henderson Using data from...
In the already complicated science of what creates - and causes constant change in - two giant doughnuts of radiation surrounding Earth, researchers have added a new piece of information: some of the electrons reach such enormous energies that they are driven by an entirely different set of phy...
/ˌreɪdiˈeɪʃn belt/ /ˌreɪdiˈeɪʃn belt/ (astronomy) a region surrounding a planet where chargedparticles(= very small pieces of matter)are held in place by the planet'smagnetic field The space mission provided new data on the Earth's radiation belts. ...
The outer radiation belt refers to a region surrounding the Earth containing high-energy electrons and various ions, encircling the inner belt and influenced by geomagnetic activity in terms of source and loss processes.

Allen belts on their way to and from the moon. Their time in that radiation-intensive region, however, was very short, in part because the trajectory was designed to pass through the thinnest known parts. With more study, astronauts can be better protected for long-term stays in Earth ...

Here we report a unique radiation belt event serendipitously observed by the Van Allen Probes in the plasmasphere during non-storm times. The plasmasphere is a torus-shaped region of cold and dense plasma surrounding the Earth, where the VLF chorus wave-driven local acceleration seldom occurs. ...
Scientists may have solved a lingering mystery surrounding the ice giant Uranus and its weak radiation belts. It's possible the belts' weakness is linked to the planet's curiously tilted and lopsided magnetic field; the field could be causing "traffic jams" for particles whipping around the wor...
