What are Some Incredible Natural Phenomena?

Auroras 1 of 11

Auroras are stunning visual displays of light, which may appear to dance across the sky. They occur when highly charged particles from solar wind collide with atoms in the earth's atmosphere at high altitude.

Aurora Borealis occurs in northern latitudes. The best places to see the Northern Lights include the Arctic, Alaska, Canada, northern Greenland, the Scandinavian coast, and Siberia.

Aurora Australis occurs in southern latitudes. You can see the Southern Lights in Antarctica, as well as the southern regions of South America, New Zealand, and Australia.

The colors you will see in the aurora vary, depending on the type of atom, as well as its altitude:

  • Oxygen up to 150 miles high produces green light.
  • Oxygen above 150 miles produces red light.
  • Nitrogen up to 60 miles high produces blue light.
  • Nitrogen above 60 miles produces purple or violet light.
