Energy source of Northern Lights found - USATODAY.com


Energy source of Northern Lights found - USATODAY.com: "Scientists think they have discovered the energy source of the spectacular color displays seen in the northern lights. New data from NASA's Themis mission, a quintet of satellites launched this winter, found the energy comes from a stream of charged particles from the sun flowing like a current through twisted bundles of magnetic fields connecting Earth's upper atmosphere to the sun."
