No. Sound is a waveform made by the compression and expansion of something called a 'medium'. Usually the medium is air. Sound is caused by vibrations passing through the air. The vibrations cause the air to expand and compress in waves from the source of the sound until it hits our eardrums and transmits the vibrations to the drum, into the ear and to the brain where we recognise it as something we call 'sound'. Of course, sound can travel through other media including water (as in echo sounding) or even in solids (try placing your ear to the end of a broomstick held on a vibrating engine - the sound is really amplified as it passes through the stick). In the vacuum of space, however, there is no air or any other medium, and therefore sound cannot travel. Light can travel through space because light is a waveform that is part of the electromagnetic spectrum (which includes radio waves, microwaves and x rays) and electromagnetic waves do not need a medium in which to travel. The absence of sound in space is often forgotten in cheap Science Fiction movies where an alien spaceship is exploded and you hear the loud bang. In real life this would never happen. The best depiction of space and the absence of sound in it is in Arthur C Clarke's 2001: A Space Odyssey directed by Stanley Kubrick. Although it is one of the greatest science fiction movies of all time, it was criticised because of periods of silence during the 'space' scenes - but of course this was a factually accurate depiction as opposed to the cheap sci-fi 'B' movies where enemy ships explode in a flash of light and a huge bang.There is no sound in outer space. Sound actually travels as pressure waves through air, and since air does not exist in outer space, there is no sound.

How fast does sound take to get from the sun?

Sound must have matter to travel through - we are used to hearing sound that travels through air. But there is no air in outer space. We have heard sound that travels through water, but, there is no water in outer space either. In fact, outer space consists of a vacuum . . . not a floor cleaner, but a condition in which there is no matter - no air, no water, no nothing. So their is no sound transmission from the Sun. Have you heard any?
