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.

00:03 Space is vast and most of it is empty, meaning sound can't propagate.
00:08 That's why marketing for the film Alien famously said, "In space, no one can hear you scream."
00:13 But sound can still be extracted from the plasma wave frequencies of cosmic signals,
00:17 with experts saying that this is what the sun sounds like.

00:26 Of course, those sounds would be much louder, likely reaching levels even on Earth upwards of 100 decibels.
00:31 But when those plasma waves come from other sources, ones that are much further away,
00:35 they often get tied up in the magnetic fields of planets.
00:38 This causes them to swirl and produce a signature sound related to that specific plasma source
00:42 and that specific magnetic field.
00:44 In fact, this is what Saturn sounds like, one of the most iconic planets with an equally iconic planetary sound.

00:56 Experts say that these types of sounds can even be derived from Jupiter's moons.
00:59 But if you're anything like me, you're no doubt wondering, "What does a black hole sound like?"
01:04 Well, it sounds like this.
