原文：Scientists have discovered that the Earth’s magnetic waves can be used to detect electrically charged particles in space. The discovery was made using data from NASA’s Van Allen Probes, which have been orbiting Earth since 2012. The Van Allen Radiation Belts are two rings of plasma that surround the Earth, and are full of fast-moving, electrically charged particles. It is hoped that the discovery will help scientists to better understand the dynamics of space weather, which can affect satellites, power grids and communication systems on Earth.
