Sun’s Energy + Oxygen + Nitrogen =

14 10 2012

The Northern Lights are actually the result of collisions between gaseous particles in the Earth’s atmosphere with charged particles released from the sun’s atmosphere. Variations in color are due to the type of gas particles that are colliding. The most common auroral color, a yellowish-green, is produced by oxygen molecules. Nitrogen produces blue or purplish-red aurora. Photo Credit: Johanna Schumacher
