Giant particle accelerator in the sky – Phys.org

The Earth’s magnetic field traps high-energy particles. When the first satellites were launched into space, scientists led by James Van Allen unexpectedly discovered the high-energy particle radiation regions, which were later named after its discoverer: the Van Allen Radiation Belts. Visualized, these look like two donut-shaped regions encompassing the planet.
Now, a new study led by researchers from GFZ German Research Center for Geosciences shows that electrons in the radiation belts can be …
