Colorful lights of Aurora Borealis appears over Lapland, northern Sweden. Aurora is produced by the collision of high-energy charged particles, originated from the sun, with atoms and molecules of Earth's atmosphere (at altitudes above 80 km). The vivid green and purple auroral colors are caused by high atmospheric oxygen and hydrogen reacting to a burst of incoming electrons. Babak Tafreshi, Dreamview.net
