Alongside its Southern neighbour Aurora Australis, the Northern Lights (also known as Aurora Borealis) is truly Mother Nature at her finest.
These spectacular natural artworks put the colours of the world on display. Here are our favourite photos of the Northern Lights taken by Greenpeace photographers in the Northern hemisphere.
How are the Northern Lights formed?
Charged particles emanating from the sun stream towards earth and then collide with the highest air particles. The color we see is a direct result of which gases are in the atmosphere. Oxygen produces the most common yellow-green color and the violet we often see at the lower edge of the aurora is due to nitrogen.
