I just wanted to put up some cool pictures of the northern lights. My group is doing a presentation on a trip to Northern Europe, so I've been looking at pictures of the Aurora Borealis recently and I have come across some very cool ones.
This one is from a tour company called BenTours
This one is from and Icelandic Tour company called Iceland2Go
And this one is my favorite. it is of the Northern Lights viewed from the flight deck of an airliner. It was taken by United Airlines First Officer Ken Wien.
