The Aurora Borealis is a Latin designation for the Northern Lights, the celestial light phenomenon often observed in the night sky during the winter season, usually in the polar zone. Aurora was the Greek goddess of the dawn. Auroras are derived from tiny solar particles that form plasma clouds of electrons and protons, created during electronic storms on the sun. While these are traveling through space, they become trapped in the Earth's magnetic field and collide with atoms of gases in the upper atmosphere (at an altitude of 100-250 km). These atoms start to glow and then emit bands of light that form the Northern Lights.
