If only for the headline that sounds like a terrible B-grade movie, I like this "Solar storm creates killer zombie satellite" story on BoingBoing. Apparently a solar storm knocked a satellite called "Galaxy 15" partially offline, so all it's doing now is traipsing around in orbit blasting random "C-band" telecoms signals and generally interfering the hell out of other satellites until it dies or gets turned away from Earth. At that point it becomes a "here we are and we're really bad with our own technology" beacon to attract ravaging alien races. Hurrah!

PS - Apparently this kind of thing has happened before.
PPS - It must not be too big a problem, or we would have tried to shoot them down.
