The Northern Lights over Norway…

Photos courtsey of www.Spaceweather.com
The reds and blues are really rare! The varieties of gases in the atmosphere are what cause the varied colors in the northern lights.
Hydrogen, helium, nitrogen and oxygen collide with the solar charged particles and result in the yellow, blue, purple, red, and green colors emitted by the lights.
(Green is oxygen, red hydrogen, and blue nitrogen).
