AURORA

Arctic Circle, Aurora Borealis (Northern Lights) and Antarctic Circle, Aurora Australis (Southern Lights)

   An Aurora, sometimes referred to as a polar light, is a natural light display in the sky, predominantly seen in the high latitude regions.

Northern latitudes, Arctic Circle, aurora borealis (or the northern lights)

The aurora borealis, or northern lights, appears when solar wind particles collide with air molecules in the earth's atmosphere, transferring their energy into light.

Southern counterpart, Antarctic Circle, aurora australis (or the southern lights), has features that are almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone.
