Despite what you’ve heard, there are actual sounds in space.
Due to the virtual vacuum in space, it’s not sound like you and I experience it (that being waves pulsing through the air), but there are electromagnetic waves that pulsate at the same wavelength as the sound waves we can hear.
Instruments on several NASA probes including Voyager have recorded these waves and translated them into a sound that we can hear, and they are all kinds of spooky. This is the kind of thing you hear in a movie just before someone opens a door in a dark hallway.
So, take a listen to the true nature of the solar system. And sleep tight.
