One of the unique joys of a visit to the Arctic is to witness the spectacular light show in the sky known as the northern lights. Also referred to as the aurora borealis, this natural phenomenon occurs when the solar winds energize the magnetosphere and charge electrons to give off dramatic hues. The aurora can sometimes be seen directly overhead; at other times the bands of color illuminate the horizon, or even make it appear as if the sun is rising from a new direction.
