I have made some fantastic friends in my years on the Internet. One of those is my buddy Ken who lives up in Canada in the Sarnia/Port Huron area. I met Ken back when we were trying to figure out if you could do such a daft thing as create digital slideshows with music (and back then rudimentary was pretty much the best you could wish for) over at the Pics2Exe forum hosted by WnSoft.
Well, out of the blue, Ken sends me a link to one excellent article in the Globe and Mail explaining what causes the aurora borealis to erupt in the winter skies over the poles (actually, they always happen but you can't see them in the summer). Oddly enough I just posted an entire gallery up of my aurora photographs for everyone to look at, there's also a pretty cool slideshow feature to use as well.
So enjoy the article, get a little ed-ju-ma-ka-shun while you're there then pop on over to the gallery and "oohhh" and "aahhh" at what happens in Alaska's night skies.
