NASA’s Van Allen Probes discover particle accelerator in the heart of Earth’s radiation belts

New results from NASA’s Van Allen Probes now show that the acceleration energy comes from within the belts themselves. Particles inside the belts are sped up by local kicks of energy, buffeting the particles to ever faster speeds, much like a perfectly timed push on a moving swing.
