NASA finds unusual origins of high-energy electrons

NASA finds unusual origins of high-energy electrons Greenbelt MD (SPX) Nov 16, 2016 - High above the surface, Earth's magnetic field constantly deflects incoming supersonic particles from the sun. These particles are disturbed in regions just outside of Earth's magnetic field - and some are reflected into a turbulent region called the foreshock. New observations from NASA's THEMIS mission show that this turbulent region can accelerate electrons up to speeds approaching the speed ... more
