Purple green hues of Aurora Borealis over forest

Colorful hues shimmer through night sky – The Northern Lights, or Aurora Borealis, lights up the night sky over the remote wilderness of Alaska. The aurora is made up of blue, green and red light, with color variations occurring at different altitudes as varying levels of oxygen emit light. This natural phenomenon has the strongest aurora activity during spring and fall equinoxes.
