Today's Astronomy Picture of the Day reaffirms why the aurora borealis is one of those things that I simply must see sometime during my life. (The other big one being the Grand Canyon, with an honorable mention going to Ireland.)

It's a cool site in general, and you can find such awe-inspiring pictures as this and this (click on them for a larger versions) in the archives. Check out this interesting perspective on a solar eclipse.
