Electric Sky

Executive summary by darmansjah

SKY Solar wind particles travel 93 million miles (150 million km) before becoming visible as the aurora borealis.

The aurora borealis, or northern lights, blasts through the sky above Crow Creek mine near Girdwood, Alaska. The red and green colors are produced by charged particles interacting with oxygen at different layers of the atmosphere.
