Aurora Borealis caused by electrical space tornadoes
THEMIS space probes discovered that the Northern lights are seen when electrical tornadoes, rotating faster than a million miles an hour, hover about above the earth. The energy spins down to the Earth's ionosphere where the tornadoes become unstable, and interact with the Earth's magnetic field. Professor Karl-Heinz Glassmeier, director of the Institute for Geophysics and Extraterrestrial Physics in Braunschweig Germany, explains, "When these space tornadoes reach the upper atmosphere their enormous energy heats the air so strongly it starts
