Space is vast and most of it is empty, meaning sound doesn’t propagate… that’s why marketing for the film Alien famously said “in space no-one can hear you scream”. However, sound can still be extracted from the plasma wave frequencies of cosmic signals and this is what some of those sound like.

00:00Space is vast, and most of it is empty, meaning sound can't propagate.
00:08That's why marketing for the film Alien famously said, in space, no one can hear you scream.
00:13But sound can still be extracted from the plasma wave frequencies of cosmic signals,
00:18with experts saying that this is what the sun sounds like.
00:26Of course, those sounds would be much louder, likely reaching levels, even on Earth, upwards
00:30of 100 decibels.
00:31But when those plasma waves come from other sources, ones that are much further away,
00:35they often get tied up in the magnetic fields of planets.
00:38This causes them to swirl and produce a signature sound related to that specific plasma source,
00:43and that specific magnetic field.
00:45In fact, this is what Saturn sounds like, one of the most iconic planets, with an equally
00:49iconic planetary sound.
00:56Experts say that these types of sounds can even be derived from Jupiter's moons.
01:00But if you're anything like me, you're no doubt wondering, what does a black hole sound
01:03like?
01:04Well, it sounds like this.
