1. Van Allen beltnoun

   Either of two torus-shaped areas of high-energy charged particles which partly surround Earth, trapped by its magnetic field. The areas are characterised by intense radiation. When the belts "overload", particles strike the upper atmosphere and fluoresce, causing the polar aurora.

2. Van Allen beltnoun

   Any of similar areas around another planet.

3. Etymology: From James Alfred Van Allen, US physicist.

1. Van Allen belt

   A Van Allen radiation belt is a zone of energetic charged particles, most of which originate from the solar wind, that are captured by and held around a planet by that planet's magnetosphere. Earth has two such belts, and sometimes others may be temporarily created. The belts are named after James Van Allen, who is credited with their discovery. Earth's two main belts extend from an altitude of about 640 to 58,000 km (400 to 36,040 mi) above the surface, in which region radiation levels vary. Most of the particles that form the belts are thought to come from solar wind and other particles by cosmic rays. By trapping the solar wind, the magnetic field deflects those energetic particles and protects the atmosphere from destruction. The belts are in the inner region of Earth's magnetic field. The belts trap energetic electrons and protons. Other nuclei, such as alpha particles, are less prevalent. The belts endanger satellites, which must have their sensitive components protected with adequate shielding if they spend significant time near that zone. In 2013, the Van Allen Probes detected a transient, third radiation belt, which persisted for four weeks. Apollo Astronauts going through the Van Allen Belts received a very low and non-harmful dose of radiation.

1. van allen belt

   The Van Allen Belt is a zone of energetic charged particles (mostly protons and electrons) from the solar wind that are captured and held around a planet by its magnetic field. Earth has two such belts, the inner and outer Van Allen Belts, which are located in the inner region of Earth's magnetosphere. The belts are named after James Van Allen, the scientist who discovered them in 1958.
