Aurora over the North Pole on April 17, 1999 (WMS) (2004)
2004 · Short film
Synopsis
When the charged particles flowing outward from the Sun (the solar wind) hit the Earth's magnetic field, they are channeled down the magnetic field lines to the ionosphere at the North and South Poles. The impact of these particles on atmospheric molecules causes the molecules to emit light, which forms the visible aurora. This visualization shows the development of the aurora over the North Pole for about three hours on April 17, 1999, as seen by the ultraviolet VIS Earth Camera on the POLAR…
