Ultra-fast electrons explain third radiation ring around Earth

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 physical processes. These results were published in a paper in Nature Physics on Sept. 22, 2013.
