TIME Features Dazzling Photos of Northern Lights Over Iceland

From TIME:

The Northern Lights, more properly known as the Aurora Borealis, have long enchanted visitors to Iceland.

Mostly green – the result of wind interaction with oxygen molecules about 60 miles above the earth – they can sometimes glow red when higher altitude molecules are encountered. Captured here in all their glory by photographer Ragnar Th. Sigurdsson, it’s not hard to see why they are one of the country’s top attractions.
