Imagine falling into Uranus: you'd first see its cool ring system and the turquoise bands of its swirling atmosphere, with hydrogen sulfide ice clouds getting darker as you go deeper. The atmosphere is freezing cold, and the pressure is about half of what we have at sea level on Earth, so without a special spacesuit, you wouldn’t stand a chance. If you made it to the bottom of the cloud layer, the pressure would skyrocket to over 60 atmospheres. The deeper you sink, the hotter it gets, with pressures so immense they could turn carbon atoms into diamonds. After weeks of descending thousands of miles, you'd reach the center of Uranus, trapped in a hellish ocean forever due to the extreme heat and crushing pressure. #brightside

00:00If you spent even a couple of seconds on Uranus, you would never come back.

00:05But let's pretend that you have a super-protective spacesuit and see what it would be like if

00:09you fell into this mysterious ice giant.

00:13Prepare for a strange, smelly, and very chilly adventure.

00:17As you approach the planet, first you encounter its rings.

00:21Yes, it has rings, just like Saturn.

00:24A whole 13 of them.

00:26Now, the not-so-great news.

00:29Uranus isn't a rocky surface planet like Earth.

00:32It's an ice giant.

00:34In other words, a swirling ball of toxic gas with no solid surface.

00:39And it smells awful, too.

00:41The upper atmosphere is filled with a gas called hydrogen sulfide, famous for its bad

00:47odor, making Uranus smell rather unwelcoming.

00:51As you descend into the planet, you'll find yourself surrounded by a dense bluish

00:55atmosphere with some turquoise hue and icy clouds.

00:59It's foggy everywhere.

01:02The temperature drops drastically to a bone-chilling minus 371 degrees Fahrenheit.

01:08Now, the real surprise.

01:11You might find yourself in a rain shower of diamonds.

01:15Uranus has a methane-rich atmosphere.

01:17As you fall into Uranus, you encounter progressively higher pressures and temperatures.

01:23Under the intense pressure, methane molecules undergo a process of crystallization.

01:28They break apart, and the atoms within them rearrange themselves, forming tiny diamond

01:33particles.

01:35The diamond particles then fall deeper into the planet, looking like a crystal shiny rain.

01:41That would be beautiful if only the freezing temperatures and the squeezing feeling weren't

01:46so distracting.

01:47Yeah, it's not all sparkles and shine.

01:51Being on Uranus would feel like being super deep underwater.

01:55If you reach the bottom of the clouds, the pressure would rapidly increase to above 60

02:00atmospheres.

02:01Winds reaching up to 560 miles per hour will buffet around you, making it three and a half

02:07times stronger than a Category 5 hurricane on Earth.

02:11For the record, this is the highest rating a hurricane can reach.

02:16Next, you're approaching the mantle.

02:18It's a dense fluid made of water, ammonia, and methane ice.

02:23It's pitch black, and the extreme gravity makes movement nearly impossible.

02:28If you weren't wearing a magical protective suit, the intense pressure could turn your

02:32carbon-based body into diamonds before reaching the core.

02:36Now, remember that Uranus is a huge planet.

02:41Its diameter is about four times the size of Earth.

02:45If our planet were a nickel, Uranus would be a softball.

02:48So, all this sinking would take literal weeks.

02:52You could have traveled thousands of miles into Uranus and possibly found its center.

02:57And after that, you'd be stuck within this hellish ocean forever due to the scorching

03:02temperatures and pressures.

03:04Not the best trip ever.

03:07Even though we didn't send any probes there, there are many things we know about Uranus.

03:12It's the seventh planet from the Sun and the coolest member of our solar system.

03:17It's 1.8 billion miles away from our star, which means that it takes sunlight almost

03:23three hours to reach it.

03:25No wonder it's so cold there!

03:28This planet also has a pretty weird feature.

03:31It spins on its side.

03:33While most planets twirl on their axes like tops, Uranus rolls along at a nearly 90-degree

03:39angle, giving it a sideways spin.

03:42You can imagine it like a rolling ball orbiting the Sun.

03:47A day on Uranus is shorter than on Earth, a mere 17 hours.

03:51However, the length of the year there is insane, around 84 Earth years!

03:57Plus, its equator is practically doing a right-angled dance with its orbit, leading to the most

04:02extreme seasons in our solar system.

04:05Which means that if it were habitable, we'd have shorter days but longer and very crazy

04:12seasons.

04:13We already mentioned that Uranus and Neptune are both blue.

04:17That's because, unlike their siblings Jupiter and Saturn, ice giants have heavier elements

04:22and methane-rich clouds.

04:24Methane absorbs the red part of sunlight, leaving us with that signature hue.

04:29And we don't know for sure, but these planets might even hide methane lakes, or entire oceans.

04:36And finally, it has not only rings but also moons, 27 of them actually.

04:43The moons are named after characters from Shakespeare and Alexander Pope, adding a literary

04:49flair to the planet's Greek name origins.

04:52Now, what would it be like to fall into another ice giant, Neptune?

04:58It's the farthest, most mysterious planet in our solar system.

05:02We know barely anything about this big dark blue planet.

05:06Just like with Uranus, we start with rings.

05:09We don't know much about them except that Neptune has five main rings, which are pretty

05:15young with huge clumps of dust around them.

05:18You might notice that the planet's blue hue is much more vibrant than Uranus.

05:24Scientists aren't sure why, but they think it might be due to an unknown component complementing

05:29the methane.

05:30You won't see much once you're inside, though.

05:33The sunlight is as scarce as a dim twilight on Earth.

05:37Since it's the most distant planet, it takes the light a full four hours to reach it.

05:43Neptune is also smaller than Uranus.

05:46This time, if Earth were a nickel, Neptune would be a baseball, which means that falling

05:50into it would take much less time than into Uranus.

05:55Neptune might look calm on the surface, but trust us, it's absolutely horrifying.

06:02Despite its appearance, it's a planet of storms and icy oceans.

06:06The temperatures are, once again, insane.

06:09Around minus 350 degrees Fahrenheit, winds here are fierce too, three times stronger

06:16than Jupiter's and nine times stronger than Earth's.

06:20So be smart about your landing, even though there's nothing to land on.

06:24Choose the northern hemisphere for tamer winds, and don't forget to pack your spacesuit with

06:29extra oxygen.

06:31About 80% of Neptune is made up of a chilly mix of water, methane, and ammonia, so there's

06:38no chance to get a breath of fresh air.

06:41The atmosphere is full of gases, but feels fluidy.

06:45It blends seamlessly into water and icy substances until you reach a solid core deep, deep down.

06:53So it will literally feel like you're sinking, especially considering the insane ocean-like

06:58pressures.

06:59There are also some cool theories that there might be a super hot water ocean beneath Neptune's

07:05cold clouds.

07:07There's an upside though.

07:09Just like on Uranus, the extreme conditions might turn carbon atoms into dazzling diamonds,

07:14sparking into the planet's core.

07:17Although you probably wouldn't see them sparkling beautifully, since it's so dark everywhere.

07:23At least that's how we imagine it based on all the current data.

07:27While we've explored almost every corner of our solar system, our faraway giants, Uranus

07:33and Neptune, remain elusive.

07:35We've got some pictures and data thanks to NASA's Voyager 2 spacecraft, which zipped

07:40past Uranus and Neptune in the 80s.

07:43However, that might change soon.

07:46NASA and the European Space Agency, ESA for short, have made visiting these distant ice

07:51giants a top priority.

07:54They even tried to get a glimpse of what it's like to descend into their atmospheres.

07:59They conducted exciting simulations, trying to recreate the conditions of these planets

08:03to see what it would be like for their probe to brave into the unknown, battling temperatures

08:09and pressure in the icy clouds.

08:12The tests happened in Europe's fastest wind tunnel, the T6 Stalker Tunnel at Oxford University

08:18and the plasma wind tunnels.

08:20The probe was heated up, because even though the icy giants are super cold, the probe would

08:25heat up significantly upon entry.

08:28The speeds of the T6 Stalker Tunnel reach around 12 miles per second.

08:33But for these tests, scientists want to push all the boundaries and reach around 15 miles

08:38per second.

08:39That's the speed required for orbiting distant planets.

08:43But it would take some time for us to adapt our technology to that.

08:46However, when we finally manage to send a probe to Uranus or Neptune, the journey will

08:51be exciting.

08:53It would have to spend decades traveling through the outer reaches of their solar system, passing

08:57by Jupiter and Saturn along the way.

09:00Collecting data from these planets could help us unlock secrets about their nature and history,

09:06and help us understand our solar system much better.

09:09Let's hope we'll learn more about these two fascinating worlds!
