Sound is carried by vibrations of some material; normally vibrations in the atmosphere. Sounds can also be carried by vibrations in the ground or in the water. If you've ever seen old western movies, you might have noticed the scout putting his ear to the ground to "hear" far-off hoofsteps. Or if you've ever been at the ocean, you might have noticed that when you put your head under water, you can hear the sounds of fish, or ships, very clearly.
There is no atmosphere in space, so there is no medium that can carry sound. However, if you were outside of a spaceship and you touched your space helmet to the hull of the ship, you'd be able to hear sounds within the ship; perhaps even the voices of people talking inside the ship.

Answer 2
Sound waves need material medium to travel. In space there is nothing. Hence there is no sound. But it is wrong to say there is nothing as there is an ocean of particles in outer space. So the sounds that are produced is too low for any person to hear. Scientists have been able to capture these sounds and amplified it so that anyone can hear it.
