So there really is sound in space. And here I've been laughing at all of those scifi flicks that have sound effects when a spaceship explodes.

That's cool.
I remember watching an EVA when they were building the ISS, and the astronaut was performing a procedure that required releasing some gas from a valve on the space station, and when he did it, he said he heard the hissing sound of the gas right through his space helmet!
EVA = extra-vehicular activity
ISS = International Space Station
