Natural plasmas

In nature plasmas can occur in very hot environments existing in stars like our sun or in lightnings during a thunderstorm. However, a plasma does not necessarily need a hot environment. This is demonstrated by natural phenomenons produced by charged particles of the solar wind called aurora borealis (north sphere) or aurora australis (southern sphere) occurring mostly at the skys in regions near the earth’s magnetic poles. A beautiful example of an aurora borealis dancing at the sky is shown in the movie by Tor Even Mathisen:
