Auroras or the Northern Lights are in my bucket list - I know that they are caused by the collision of solar wind with the Earth's magnetic field but I can't help to feel that these phenomenons are but a small display of how majestic Mother Nature can be.
Anyway, until I can haul my lazy butt to the (very far and very cold) polar region, these fantastic photos of auroras by Dennis C. Anderson of Night Trax Photography have got to suffice. They're some of the most beautiful photos I've ever seen.
This one to the left, titled A Colorful Dawn, was taken back in 2003 in Homer, Alaska. Check out the entire gallery here (not to be missed!): Link (you can buy prints there, too)
It was a hot weekend, and while taking the time-lapsed photos, I had to seek shelter from the mosquitoes.
