The Biggest Screen In the World
Approximate Running Time: 7 minutes
The grandiose spectacle of the polar auroras turn the firmament, when seen from high latitudes, into a gigantic screen onto which their beautiful hypnotic images are projected, just as cathode ray tub es form images on our television sets. Charged particles from the solar wind follow a path determined by the Earth’s magnetic field and then interact with atoms in the atmosphere like the electrons in the TV set that are aimed by a powerful electromagnet to form images on the screen as they hit its phosphor layers.
