Space is a virtual vacuum. Sound does exist in the form of electromagnetic vibrations that pulsate in similar wavelengths.
NASA have designed special instruments that can record electromagnetic vibrations, and transfer them into sounds that our ears could hear. In recent years, astronomers found a supermassive black hole humming 250 million light-years away from Earth, residing in the Perseus cluster. They observed ripples in the gas filling this cluster, producing the deepest “note” detected from any object in the universe – a B-flat, 57 octaves below middle C. This is a million billion times deeper than the lowest frequency of sound we can hear!
We often say that sound is impossible to come across in space, as The particles are so spread out, and the resulting sound waves are of such a low frequency, that they're beyond the capabilities of human hearing. It's been the case that sounds of very strong earthquakes are sometimes intense enough to make it out into space, and infrasound can carry on going where normal sound has to pull up. This is something that I'm definitely taking into consideration if I wish to utilise sound in different ways in the Trans-media piece.
Scientists have gathered that a short amount of time after the Big Bang (about 760,000 years), the Universe was dense enough for normal sounds to pass through it. If you hear the sound of a planet or spacecraft exploding in a Star Wars movie, its a craft by filmmakers that sound can be heard, both to generate atmosphere and to create anticipation.
There have been actual recordings from planets in the solar system for example:
