Unusual high-speed electrons spotted outside Earth's magnetic field

Mysterious High-Speed Electrons Have Been Spotted Outside Earth’s Magnetic Field, And NASA Says It Could Change Particle Physics Forever

Astronomers at NASA have discovered electrons that reside outside the Earth's magnetic field which somehow get super-accelerated once they fall into a turbulent region called the foreshock. High above the surface, Earth’s magnetic field constantly deflects incoming supersonic particles from the sun, but these particles are disturbed in regions just outside the magnetic field and some that get reflected into the foreshock region accelerate almost at the speed of light. And observation from from NASA’s THEMIS (Time History of Events and Macroscale Interactions during Substorms) mission revealed that this turbulent region is responsible for the creation of high-speed electrons.
