Aurora Borealis
Aurorae are natural light displays that usually occur in Polar Regions, during the months of September and October, as well as March to April. Named after the Roman Goddess of Dawn and the Greek term for north wind, Aurora Borealis are created by the collision of charged particles from the earth's magnetosphere. These collisions electrically excite the particles, causing them to release energy in the form of light. Capturing an image of this phenomenon used to be extremely difficult. However with the development of digital cameras that have high sensitivities, capturing an image of the aurora has become more convenient.
