In space, no one is supposed to hear you scream. Or hear anything else for that matter. That, however, is not entirely true. Just because there’s no medium to carry sound like we have on Earth doesn’t mean that acoustic pressure waves aren’t generated above and above and beyond our atmosphere. There IS sound in space; we just can’t hear it. Unless, of course, we have very special listening tools.
The European Space Agency has such tools. The agency has just released a whole whack of space sounds under Creative Commons license, meaning that you can do whatever you want with them. Let’s take a listen to a comet sing, an ISS siren, a probe land on a comet and the wails of a meteor shower.
