NASA's Van Allen Probes Detect Life-Protective Electron Barrier Inside Earth's Radiation Belts

A visualization of the Earth’s radiation belts, based on data that were gathered by NASA’s twin Van Allen probes. The Earth is seen to be surrounded by the plasmapause (blue-green area) and the two main radiation belts further out (multi-color area). The boundary between the plasmapause and the inner edge of the outer […]

NASA's Van Allen Probes Going Strong After Two Years of Studying Earth's Radiation Belts

NASA’s Van Allen Probes orbit through two giant radiation belts surrounding Earth. In the time since launching two years ago, the probes have discovered a third radiation belt, and other observations have helped explain how particles in the belts can be sped up to nearly the speed of light.Image Caption and Credit: NASA

Using data from a NASA satellite, scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe and known as the Van Allen radiation belts.
