Unpredictable and erratic, but astounding, the Aurora Borealis is nature's most magnificent light show. More commonly known as the Northern Lights, when the spectacle is in full flow iridescent colors dance across the Arctic night, setting the sky ablaze with a range of cosmic greens, reds and yellows.
The natural phenomenon can be seen in the northernmost regions of the world, including Norway, Iceland, Greenland and Alaska, and is the result of electrically charged particles colliding in the Earth's atmosphere.
Sightings are notoriously difficult to predict and cannot be guaranteed, but if you want to chase the elusive lights, right now is the best time to head up north. And to make a sublime experience even more spectacular, you should see the lights by boat.
