There is no sound in space as vacuum doesn't transmit it. There is nothing the sound waves could move through. So it's pretty silent out there.
That is actually a good thing. Our soundscape would be quite different if we could hear the loudest sound in our solar system. Despite being 150 million kilometers a way, that huge explosion in the sky that we call sun would generate a sound that would hit us at 125 Desibels. That's about the same as a sound of a jet engine from a close distance. So it would be quite deafening.
