There is probably occational explosions, I don't think we can hear through our atomsphere. But may? Travel far without an atomsphere, I don't know, but curious.

Sound is a vibration transmitted through some medium - water, air, etc. Space is nearly a vacuum, hence no medium for transmission. If you could build a big enough and sensitive enough "ear", you might hear something.

Here's a sound that was detected from across space :)

But in general, for sounds that your ear is sensitive to, there is no sound.

Because in space there is no vacuum. This is because of vacuum only we will say.

Scleros is correct - no molecules close enough together to vibrate, thereby creating sound.

[On of my fav cartoons is guy in lab coat (scientist) in movie theater shouting "There is no sound in space!"]

And do you know why there's a vacuum in outer space? Because the whole world sucks. Just kidding... <G>
