Why Saturn Is the Scariest Planet in the Solar System (Its Beautiful as "Hell" 🫢)

[00:00:14]Don't adjust your volume.

[00:00:17]That is not a soundtrack. That is not a sound effect added in post.

[00:00:23]That is Saturn.

[00:00:26]NASA's Cassini spacecraft recorded that sound as it passed through the planet's magnetic field.

[00:00:33]Electromagnetic waves translated into audio.

[00:00:38]A planet producing its own alien soundtrack in the vacuum of space where sound isn't supposed to travel at all.

[00:00:47]For 400 years, we looked at Saturn through telescopes and called it the jewel of the solar system.

[00:00:55]A golden beauty.

[00:00:57]A halo of perfect rings floating in the dark like something out of a dream.

[00:01:03]We called it peaceful.

[00:01:05]We were catastrophically wrong.

[00:01:08]Saturn is a violent impossible colossus.

[00:01:12]A world of geometric storms, planetary [music] graveyards, alien oceans, and a gravity so merciless it tears [music] entire moons apart just to make itself look pretty.

[00:01:25]By the end of this video, you will never look at Saturn the same way again.

[00:01:31]This is the lord of chaos. Before we even get to the rings, let's talk about the planet itself because Saturn is already deeply wrong. It is a ball of hydrogen and helium. No solid surface.

[00:01:47]If you tried to land on Saturn, you wouldn't hit ground. You just keep sinking. The gas would get denser and hotter and more more until the pressure finally turned you into a smear of atoms. There is no floor.

[00:02:02]There is no bottom. There is just in.

[00:02:05]Saturn spins so fast, one full rotation every 10.7 hours. That centrifugal force literally squashes it. It's not a sphere. It bulges at the equator and flattens at the poles. It is technically the shape of a pumpkin. The most perfectly ringed planet in our solar system is shaped like a pumpkin. Here's something that will break your brain.

[00:02:31]Saturn is the least dense planet in the solar system, less dense than water. If you could find a bathtub large enough, and we're talking a bathtub the size of a small ocean, Saturn would float in it.

[00:02:44]A planet made mostly of gas, lighter than water, shaped like a pumpkin, spinning faster than anything should, and it has been doing this for 4 and 1/2 billion years. Now, the rings.

[00:02:58]From Earth, they look like smooth bands of gold, solid, elegant, eternal.

[00:03:05]If you flew into them, you would last seconds. The rings are not solid. They are a blizzard of ice and rock, ranging from the size of a grain of sand to the size of a house, to the size of a mountain. All of it hurtling through space at thousands of kilometers per hour, constantly colliding, shattering, reforming. They stretch nearly 300,000 km wide, wide enough to almost reach the moon from Earth. But in some places, they are only 10 m thick. 10 m, that is thinner, proportionally, than a piece of paper, a razor blade, a planetary razor blade slicing silently through the dark.

[00:03:57]So, where did all this come from? A murder.

[00:04:01]The leading theory is one of the most haunting stories in planetary science.

[00:04:06]Long ago, possibly just 100 to 200 million years ago, recent in cosmic terms, during the age of the dinosaurs, a moon wandered too [music] close. A moon that may have been as large as Titan, the size of the [music] planet Mercury. It crossed the Roche limit. The Roche limit is the point of no return, the invisible line where a planet's gravity [music] becomes stronger than the internal gravity holding a moon together. Cross it and the planet doesn't just pull you in, it pulls [music] you apart. Saturn grabbed this moon and tore it to pieces, ripped the [music] crust from the core, shredded an entire world, trillions of tons of ice and rock into the rings we see today. Those rings that look like jewelry, they are the guts of a dead [music] world scattered across 300,000 km of space. We have been calling [music] it beautiful for four centuries.

[00:05:16]We were staring at a graveyard. Now, look at Saturn's North Pole. Go ahead.

[00:05:22]Look at it. Nature does not make straight lines. The laws of fluid dynamics, the science of how gases and liquids move, dictate that storms become circles and spirals, eddies, vortices, wheels of motion. That's just physics.

[00:05:41]Saturn missed the memo. Sitting at the North Pole of Saturn, spinning perfectly, is a hexagon, a six-sided geometric structure. Not roughly hexagonal, not kind of hexagonal, a mathematically precise hexagon. Each side almost exactly equal in length, rotating with the planet like it was drawn by a machine. Each side of the hexagon is longer than the diameter of the Earth. It has been there since at least 1981 when Voyager first photographed it. It was there when Cassini arrived in 2004. It was there when Cassini died in 2017.

[00:06:21]For all we know, it's been there for thousands of years. And it is not just a shape, it is a storm, a hurricane with six walls each reaching hundreds of kilometers deep into the atmosphere. At the very center is a massive vortex, a swirling maw of clouds, blood red and spinning like a rose made entirely of hurricanes. Scientists recreated the hexagon in a laboratory, a rotating tank of water with a small inner cylinder. It worked. They got the hexagon, which means the math checks out, which means this alien geometric storm on a distant gas giant is just physics doing its thing. That somehow makes it more unsettling, not less. Every 30 Earth years, one Saturn year, something wakes up inside the planet. We call it the Great White Spot. Deep inside Saturn's atmosphere, heat builds. It builds and builds, trapped beneath the calm-looking cloud bands until it can't be contained anymore. And then it erupts. A storm system explodes upward from the interior, breaking through the cloud tops and spreading across the planet.

[00:07:37]Not across a continent, not across a hemisphere, across the entire circumference of Saturn.

[00:07:45]The storm wraps around the whole planet.

[00:07:48]Inside it, lightning.

[00:07:50]Lightning 10,000 times more powerful than anything on Earth. So powerful that Cassini could detect the radio burst from hundreds of thousands of kilometers away. The flashes were bright enough to be seen from Earth. The golden bands that make Saturn look so serene, during a great white spot event, they disappear under churning white storms of ammonia ice that billow up from the deep. The planet changes. It becomes something else.

[00:08:26]A ghost. The last major outbreak was in 2010.

[00:08:31]It lasted for months.

[00:08:34]The storm system eventually caught up with its own tail and consumed itself in a clash of heat fronts. Saturn ate its own storm.

[00:08:45]Next one is due around 2040.

[00:08:48]Put it in your calendar. Saturn has more than 140 moons. 140.

[00:08:55]Most of them are frozen rocks and captured asteroids, barely worth a second look. But two of them might be the most important places in the solar system. First, Titan. Titan is the only moon in the solar system with a real atmosphere. Not a wisp of gas, a thick nitrogen-rich blanket of air with an atmospheric pressure 1.5 times higher than Earth's.

[00:09:22]If you stood on Titan, you'd need a heated suit, but you wouldn't need a pressure suit. The air pressure wouldn't kill you. What would kill you is everything else. Titan has rivers. It has lakes. It has coastlines, beach erosion, and rainstorms. From a satellite, it looks startlingly, disturbingly like Earth.

[00:09:45]But, the rain is liquid methane.

[00:09:49]Liquid natural gas falling in slow motion because gravity is weak from orange clouds. The lakes are filled with ethane and propane. The temperature is -179° C.

[00:10:05]If you fell into a lake on Titan, you would not drown. You would shatter.

[00:10:11]Your body would freeze so fast, so completely that you would break like glass. And the dunes, Titan has enormous sand dunes, hundreds of meters tall, are not made of silica sand. They're made of hydrocarbon particles.

[00:10:29]Essentially, plastic. Statically charged plastic dunes shifting in an alien wind made of nitrogen.

[00:10:38]Titan is Earth's evil twin.

[00:10:41]Built from the same recipe, but cooked in poison. Now, Enceladus. Small, bright, completely covered in ice.

[00:10:51]Enceladus looked boring. A frozen rock, nothing to see.

[00:10:56]Then, Cassini flew over the South Pole and found the tiger stripes. Long, deep blue fractures in the ice. And saw something that changed everything.

[00:11:07]It was bleeding. From those fractures.

[00:11:11]Geysers. Not small geysers.

[00:11:14]Massive jets of water vapor and ice crystals shooting hundreds of kilometers into space at supersonic speed. A moon so small you could drive across it in 6 hours erupting [music] like a wound that won't close. Saturn's gravity is kneading Enceladus like dough, generating tidal friction that keeps its interior warm. And beneath that frozen shell, Cassini detected something extraordinary.

[00:11:45]A global ocean, liquid water covering the entire moon. Not just water. Salty water with hydrothermal vents, with organic molecules, with hydrogen, the energy source that some of the earliest life on Earth used to survive. Every single ingredient we know of for life, liquid water, heat, chemistry, time, is sitting right there underneath that ice in the dark. We went to Saturn looking for gas and rock. We may have found a second Genesis.

[00:12:27]>> To learn all of this, to discover the hexagon, the geysers, the alien oceans, we had to send someone in. The Cassini spacecraft launched in 1997.

[00:12:39]It arrived at Saturn in 2004 after a 7-year journey across the solar system.

[00:12:46]For 13 years, it orbited the planet. It flew through the rings. It dove past Titan 127 times. It skimmed over Enceladus and tasted the geysers.

[00:13:00]>> Literally flew through them and analyzed the water with onboard instruments. It sent back hundreds of thousands of images. It rewrote our understanding of the outer solar system. And then, in 2017, it ran out of fuel. NASA faced a decision. If Cassini drifted uncontrolled, there was a chance, small but real, that it could eventually crash into Enceladus or Titan. And if there is life on those moons, even microbial life, we could contaminate it. We could end something we hadn't even discovered yet. So, they made a choice. On September 15th, 2017, NASA commanded Cassini to fly directly into Saturn. In its final hours, Cassini performed a series of maneuvers it had never attempted, threading between the rings and the atmosphere, closer to Saturn than any spacecraft had ever gone. It was sending back data from regions no instrument had ever sampled. Then, it hit the atmosphere. Cassini fought. Its thrusters fired, trying to keep its antenna pointed at Earth, transmitting data until the last possible second.

[00:14:22]Scientists on the ground watched the signal weaken, fluctuate, fight, and go silent. In less than a minute, a spacecraft the size of a school bus that had traveled 7 billion kilometers was torn apart and vaporized, scattered into the atmosphere of the planet it had spent 13 years studying. Cassini is Saturn now. We gave it back. Here is the last thing I want you to sit with. The rings are dying. Saturn's gravity is pulling ring material down into the planet's atmosphere. [music] A process scientists call ring rain.

[00:15:04]Tons of icy particles fall into Saturn every second, every minute, every year.

[00:15:11]The rings are losing mass constantly, gradually, inevitably.

[00:15:16]In roughly 100 million years, less than 1% of the current age of the solar system, the rings will be gone.

[00:15:25]Saturn will be just another gas giant in the dark, [music] unremarkable, easy to overlook. We happen to live in the brief window of time when they exist. Our entire civilization, every human being who ever lived, every war, every discovery, >> [music] >> every work of art has existed during the era when Saturn has rings.

[00:15:51]There were dinosaurs when this moon was ripped apart.

[00:15:55]There will be nothing we recognize when the last fragment falls.

[00:16:00]So, look at it while you can. Saturn is temporary. Its rings [music] are temporary.

[00:16:08]The chaos and the geometry and the alien oceans and [music] the perfect hexagon and the sound, that haunting, impossible sound, all of it is borrowed [music] time.

[00:16:24]It is the most violent, most beautiful, most improbable thing in our solar system and it will not wait for you.
