What, exactly, are VAN ALLEN Belt's?
The Belts are regions of high-energy particles, mainly protons and
electrons held captive by the magnetic influence of the Earth. A small but
very intense "inner belt" (some call it "The Van Allen Belt" because it
was discovered in 1958 by James Van Allen of the University of Iowa) is
trapped within 4000 miles or or so of the Earth's surface. It consists
mainly a high-energy Protons and is a by-product of cosmic radiation,
The short answer to how the aurora happens is that energetic electrically
charged particles (mostly electrons) accelerate along the magnetic field
lines into the upper atmosphere, where they collide with gas atoms,
causing the atoms to give off light.
In Alaska, Canada, Norway, Finland or northern Russia, on a clear night,
a greenish glow is often seen in the sky, known as the “Northern Lights”.
It often appears as a glow on the horizon, like the glow preceding
sunrise, and has therefore become known among scientists as "aurora
borealis" ("aurora" for short), Latin for "northern dawn." A similar
phenomenon is also seen in southern polar regions.
