The Northern Lights colors

The aurora colors correspond to the different types of gases in the ionosphere. Oxygen atoms give off red and green light, depending on how high they are in the ionosphere; whereas nitrogen molecules give violet light.

The most common color observed is green. During a moderate to large aurora display, which can last up to three hours, the amount of energy released is roughly equivalent to that of a small nuclear explosion.
