Which gases does sound travel through?

Sound can travel as long as there is something for it to travel through. This could be a gas (such as air), a liquid (such as water) or a solid (such as a metal). In outer space there is no air for the sound to travel though, so astronauts can not talk with each other unless they use a radio.

Can sound waves travel through the vacuum of space?

Unlike electromagnetic waves such as radio and television or light which can travel through the vacuum of space, sound waves travel by the compression and decompression of molecules in the medium through which they are passing. The medium must be compressible, whether it be gas, liquid or solid, and there are none of these in the vacuum of space.

What can't sound travel through and why?

Sound cannot travel through a vacuum, such as in outer space. "Sound" refers to waves of compression which travel through matter. When there is no matter, there can be no such waves, and therefore no sound.
