The Sun provides the energy for the aurora, but particles in the. aurora come from Earthâs own neighborhood in space. The Sunâs. energy is carried toward the Earth in the solar wind, a stream of. electrically charged particles (mostly protons and electrons) ïow-. ing out from the Sun in all directions.
Â­The aurora borealis (the Northern Lights) and the aurora australis (the Southern Lights) have always fascinated mankind, and people even travel thousands of miles just to see the brilliant light shows in the earth's atmosphere.he auroras generally occur along the auroral ovals, which center on the magnetic poles (not the geographic poles) and roughly correspond with the Arctic and Antarctic circles. There are times, though, when the lights are farther south, usually when there are a lot of sunspots.
