Thanks go out to Rogers for pointing me to this great story about how scientists have, for the first time ever, captured simultaneous images of the aurora borealis and aurora australis, and in so doing, have proven that they are mirror images of each other. (This has long been a suspicion, given that the auroras are thought to be magnetic phenomena, and that they occur around the magnetic poles of Earth.) For the brave-of-bandwidth, NASA has a 2.4 Mb QuickTime movie showing the auroras.
