Aurora Over Norway

Flowing multi-colored auroras helped to illuminate a busy sky above Tromsø , Norway. Besides the spectacular aurora pictured above, the photographer caught three satellites streaks, one airplane streak and a friend trying to capture the same sight. (Click on the high resolution version of this image to view all of the details.)


Although auroras might first appear to be moonlit clouds, they only add light to the sky and do not block background stars from view. Called "Northern Lights" in the Northern Hemisphere, auroras are caused by collisions between charged particles from the magnetosphere and air molecules high in the Earth's atmosphere. If viewed from space, auroras can be seen to glow in X-ray and ultraviolet light as well. Predictable auroras might occur a few days after a powerful magnetic event has been seen on the sun.
