The Northern Lights

The Northern Lights cast an eerie green glow across the horizon in the city of Tromso, located at the northern tip of Norway.

In a nutshell, the Northern Lights (also known as the Aurora Borealis) occur when particles from the Earth’s atmosphere collide with charged particles from the sun’s atmosphere. Scientists believe the Northern Lights happen in cycles, and are at their brightest every 11 years. The next peak period will happen in 2013.

Have you seen the Northern Lights? I tried to see them when I was in Iceland, but alas, it was unseasonably warm (and by warm, I mean 4 degrees celsius) and overcast, meaning no light show for us. It seems like it would be a very surreal experience!
