This is pretty cool: Photographer Göran Strand (who took one of the amazing comet and galaxy pictures I posted recently) went to a town in Sweden called Östersund on Mar. 17, 2013. He set up his camera and took 30 Gb of images of the dancing aurora borealis that night. Not satisfied with just having gorgeous pictures of the experience, he put them together into a virtual video tour that allows you to pan and scan through the sky as the aurorae unfolds in front of you:

I had to shrink it to fit the blog here and it doesn’t quite work the way it should, so I strongly urge you to go to his site and play with it yourself in full resolution. I’ve seen a lot of these virtual tours before, but not one that has video that plays as you move around. That’s pretty nifty. It’s fun to watch Orion and Jupiter set as the green glow from high-speed subatomic particles from the Sun slam into our atmosphere 100 kilometers up.
