00:00 If you landed on Mercury, the first thing you'd notice would be how close it is to the Sun.
00:06 It's actually the closest planet to the Big Ball of Fire and the smallest.
00:10 But it's not the hottest planet.
00:13 Venus takes credit for that.
00:20 It takes Earth 365 days to orbit the Sun, and it takes Mercury more than 3 months.
00:26 Well, 88 days to be exact.
00:30 The days are boiling hot, with a temperature reaching above 800 degrees Fahrenheit.
00:35 But on the other side of the planet, that the Sun doesn't reach,
00:38 the temperatures drop to -300 degrees Fahrenheit.
00:42 Mercury's atmosphere can't hold any heat when it's nighttime, just like a desert.
00:46 Deserts have no atmosphere, which is why they have no moisture and no clouds or rain.
00:52 If you manage to get from one end of the planet to the other,
00:55 and always stay in between the scorching heat and freezing cold,
00:58 then you can survive.
01:00 But oxygen isn't a friend to Mercury's atmosphere,
01:04 so you'd just live for as long as you could hold your breath.
01:07 Plus, there's a magnetic field that has solar winds from the Sun that create plasma tornadoes.
01:16 Venus can heat up to almost 1,000 degrees,
01:19 but gravity is really similar to that of Earth.
01:22 You can go for walks by the mountains, and even go jogging,
01:25 but the temperature will instantly melt you.
01:28 So maybe forget about those jogging sessions.
01:31 The extreme pressure would also crush you like a can.
01:34 It's like being half a mile underwater on Earth.
01:37 So you'd only last a few seconds on Venus.
01:40 The Red Planet is home to the highest mountain in the solar system,
01:44 around three times taller than Mount Everest.
01:47 And it's also a volcano.
01:49 Despite being called the Red Planet, Mars is actually really cold.
01:53 It needs a little less than two years to rotate around the Sun,
01:56 or 687 days to be precise.
01:59 And almost like Earth, it has 25 hours in a day.
02:03 The atmosphere over there is very thin, but unbreathable.
02:07 The planet has loads of dust storms that cover the entire planet,
02:11 and polar caps that are covered with carbon dioxide.
02:14 You won't freeze in your spot, but you'd need some thick clothing to keep warm.
02:18 It's possible to last as long as you can hold your breath.
02:21 On the bright side, though, you'd get to see some incredible views.
02:25 The solar system's biggest planet is the mighty Jupiter.
02:31 If Jupiter was the size of a basketball,
02:33 then Earth would just be the size of a single grape compared to it.
02:37 It only needs 10 hours to rotate around its axis,
02:40 which is a lot shorter than Earth's.
02:42 One of the best tourist attractions is the Great Red Spot,
02:45 an area with a hurricane-like storm that's lasted more than 300 years.
02:50 Oh, and the area is about twice the size of Earth.
02:53 The largest planet in our solar system needs around 12 Earth years,
02:57 or 4,307 days, to make a complete circle around the Sun.
03:02 But Jupiter's gravity is a lot stronger than Earth's.
03:05 Besides the lack of oxygen and winds that can keep you suspended in the air forever,
03:10 the immense pressure would crush you.
03:12 Visiting here won't last longer than a few seconds.
03:15 Pluto is a former planet furthest from the Sun in our solar system,
03:19 and is now considered to be a dwarf planet.
03:22 And because it's that far, it's one of the coldest places ever,
03:26 with temperatures reaching -400 degrees Fahrenheit.
03:29 Definitely bring a jacket. Or two.
03:32 Methane ice covers the mountains that soar at over 10,000 feet.
03:37 Pluto needs 248 years to orbit the Sun.
03:40 It's technically still in rotation, waiting to celebrate New Year's.
03:44 But it just needs 6 Earth days to complete a rotation around itself.
03:49 And, surprise, surprise, the air is also unbreathable.
03:53 Besides the methane floating around, nitrogen is also pretty common.
03:57 The gravity is weak, so you'd have to hold your breath while floating in the air
04:01 before freezing like an ice cube.
04:03 Again, you'd only last a couple of seconds.
04:06 The windiest planet in our solar system is Neptune.
04:09 The core is similar to that of Earth.
04:11 It has 14 moons surrounding it.
04:13 A day is kinda short compared to Earth.
04:16 You'd have only 17 hours in a single day.
04:19 And similar to Pluto, it needs more than 150 years to spin around the Sun.
04:24 Neptune is also known as the Blue Planet
04:27 because of the absorption of the red light by methane in the hydrogen-helium atmosphere.
04:32 So, besides not breathing, the pressure can also crush you, just like on Jupiter.
04:37 No one can last more than a few seconds there.
04:40 The second biggest planet is none other than Saturn, with rings surrounding it.
04:45 From far away, its rings look like one big chunk of rock spinning around.
04:49 But in fact, it's made up of many layers of ice particles and rocks
04:53 ranging in all sizes, from tiny pebbles to bus-sized objects.
04:57 The rings are shaped in such a way because of the gravity around Saturn.
05:01 A day on Saturn lasts only 11 hours.
05:04 It's very windy in the upper atmosphere.
05:06 Saturn also has plenty of moons like Jupiter.
05:09 And, just like on Jupiter, you'd be crushed by extreme pressure deep in the planet
05:14 before you can open your eyes.
05:16 You wouldn't last longer than a few seconds here, either.
05:19 Titan is Saturn's largest moon, and second largest moon in the solar system.
05:23 It has the closest Earth-like conditions compared to any existing planet or moon.
05:28 So living here should be a walk in the park.
05:30 But the cold weather will freeze you.
05:33 This moon is actually the only place in the whole solar system
05:36 that has liquid rivers, oceans, and lakes.
05:39 They're all covered with methane and ethane,
05:41 and the atmosphere is very similar to that of Earth.
05:44 It even rains here at certain times.
05:46 Our moon isn't so friendly, either.
05:49 Because of the lack of oxygen, you can just last as long as you can hold your breath.
05:53 The cosmic rays from the sun will also affect you,
05:56 but skipping along the moon craters is actually quite fun.
05:59 If you tried going to the sun, you'd vaporize in the blink of an eye.
06:03 The temperatures can reach around 27 million degrees Fahrenheit,
06:07 and that's just an estimated measurement near the core.
06:10 There are still the outer layers you need to worry about that'll also leave you in atoms.
06:14 Your best bet is to hit the brakes and take the nearest exit.
06:18 Estimated time on the sun? Less than a second.
06:21 Our little blue planet is the only place we can live in
06:24 where an average human can reach 80 years old.
06:27 We adapted to many weather conditions that aren't crazy,
06:30 with the gravity just about right so we don't feel crushed.
06:33 We can live anywhere from dry deserts to snowy ice peaks.
06:37 It's the only place that has the perfect balance for us to survive.
06:40 Scientists hope that one day we can live on planets other than our own.
06:44 Mars is the closest place that can host us,
06:47 considering we'd have to build a dome in order to live there.
06:50 Elon Musk wants to use Tesla bots as the first non-human crew to land there
06:55 and start building our future homes.
06:57 The robots can acquire information about the planet
07:00 and mimic the way humans walk and behave,
07:03 so it'll let us see what we'll need to worry about.
07:05 In all cases, humans will need to be suited up in order to come close to any planet.
07:10 Our bodies aren't designed to face such conditions
07:13 unless we evolve naturally to fit the environment.
07:16 The tardigrade is the only animal on Earth that can live in the most extreme conditions,
07:20 from the deepest oceans to the highest mountain peaks.
07:24 They shot some of these microscopic critters into space
07:27 and found out that they can live in the vacuum of space for up to 10 days
07:31 and return without breaking a sweat.
07:33 They're probably the only known creatures on Earth
07:36 that can live the longest on any planet except the Sun.
07:39 Scientists claim that if a large asteroid hits the Earth,
07:42 then tardigrades can perfectly survive.
07:45 But humans are simply not designed to live outside of Earth without the proper gear.
07:50 Oh, wow! There's a hole in the bottom of the ocean!
07:53 It seems that the ocean has a leak.
07:55 But it's not like a leak you would expect, where water is flowing out.
07:59 It's more like a spring since water is flowing in, not out.
08:03 This unique leak is something we know as Pythia's Oasis.
08:08 A grad student was the one who accidentally discovered it.
08:11 He noticed bubbles that were rising to the surface.
08:14 Normally, bubbles in the ocean tell us there might be some hydrothermal vents,
08:19 which are hot spots for some pretty cool things.
08:22 These vents are actually like hot springs on the seafloor.
08:26 But instead of bubbling with warm water,
08:28 they release a fluid that has been superheated in the crust of our planet.
08:32 When seawater seeps into these cracks and travels deep into the crust,
08:37 it comes into contact with the extremely hot mantle.
08:41 This heats seawater to very high temperatures.
08:44 And as it moves back up towards the surface, it carries dissolved gases and minerals.
08:49 When the hot fluid shoots out of the vents,
08:52 it mixes with the surrounding seawater and quickly cools down.
08:55 Just a short distance away from the vent,
08:58 the temperature can drop to a comfortable 68 degrees Fahrenheit or so,
09:02 which is, as it seems, exactly what some creatures like.
09:07 And there are some real weirdos living down there in the darkness,
09:10 like ghostly fish, giant red-tipped tube worms,
09:14 and a unique type of shrimp with eyes on their back.
09:17 Some of them, like tube worms and bacteria,
09:19 rely on the chemicals and minerals released by the vents to survive in harsh conditions.
09:25 But in this case, the bubbling water didn't come from a hydrothermal vent.
09:30 It was there because of a spring. And that's a bit more concerning.
09:34 You see, the water in this reservoir needs to stay where it is.
09:38 If too much of it seeps out, there could be some serious consequences,
09:42 especially for the surrounding area.
09:45 You can see this unusual leak along the Cascadia subduction zone,
09:49 which is a massive fault line off the Pacific Northwest coast.
09:53 It's a place where two pretty big plates that make up Earth's crust
09:57 come together and slide along each other.
10:00 The water from Pythia's oasis kind of acts as a lubricant between these plates.
10:05 You can think of the fault zone as an air hockey table.
10:08 When the fluid pressure is high, it's like you've turned the air on.
10:12 That means the friction between the plates is reduced, which allows the plates to move.
10:17 But if the fluid pressure is lower, the two plates can lock together,
10:21 which then leads to the buildup of stress.
10:24 Not that they'll feel bad.
10:26 In the context of tectonic plates, stress is some pressure or force that can cause deformation.
10:32 And if this stress starts to build up, at some point, it's got to go somewhere.
10:37 When it's too much, it can trigger earthquakes, and most likely not small ones.
10:42 For example, a release of stress in the Cascadia subduction zone
10:46 could lead to a magnitude 9 earthquake.
10:49 For comparison, the biggest earthquake we've ever recorded happened in Chile in 1960,
10:55 and it had a magnitude of 9.5.
10:58 The damage was enormous.
11:00 So we hope the water will stay in its reservoir
11:03 and keep maintaining the delicate balance between the tectonic plates.
11:07 Now imagine a place where a single day lasts longer than a whole year.
11:11 On Venus, a day, meaning one full spin on its axis, is as long as 243 Earth days.
11:18 And what's even weirder, despite the fact that Venus is experiencing a never-ending day,
11:24 it has a shorter year than Earth.
11:26 While Earth takes about 365 days to complete one orbit around the Sun,
11:31 Venus does it in just 225 days.
11:34 So, somehow, for Venus, a day is more epic than a whole year.
11:39 Venus is a strange planet in general.
11:42 It's called Earth's twin because of how alike we are,
11:45 although it's a bit smaller than Earth.
11:47 But there are some drastic differences too.
11:50 For example, it spins in the opposite direction,
11:53 which means the Sun there rises in the west and sets in the east.
11:57 And Venus isn't the only one who dances to its own rhythm.
12:00 Uranus does that too.
12:02 And finally, Venus is quite crazy in terms of its atmosphere.
12:06 When you stand on Earth, you don't really feel the weight of the air around you.
12:10 While on Venus, that feeling would be like having an elephant sitting on your shoulders.
12:15 Venus has 90 times the atmospheric pressure of Earth.
12:19 The atmosphere there is a thick layer of toxic gases.
12:22 For example, carbon dioxide that's released by all the volcanoes.
12:27 It presses down with incredible force.
12:29 This results in very hot temperatures.
12:32 No wonder it'll take a long time before we'll be able to stand on this planet.
12:37 Meanwhile, Mercury, the closest planet to the Sun,
12:40 has an even more speedy orbit than Venus.
12:43 It completes a full journey around the Sun in just about 88 Earth days.
12:48 However, it has a slow spin on its axis,
12:51 which means that one day on Mercury takes about 176 Earth days.
12:55 Basically, half a year.
12:57 Just like with Venus, a day there takes much longer than a year.
13:01 Since it's closest to the Sun,
13:03 no wonder Mercury experiences some super extreme temperature swings.
13:08 Daytime temperatures can soar up to a scorching 800 degrees Fahrenheit,
13:12 hot enough to melt lead.
13:14 But wait for the sunset.
13:16 At night, it drops to freezing -290 degrees Fahrenheit.
13:20 That's because Mercury doesn't have a thick atmosphere like we do,
13:24 so the heat doesn't distribute across the planet evenly.
13:28 If one side is in the dark, it'll be super cold,
13:31 and the other side will be scorching hot,
13:33 just like if you let a regular big rock lie down under the Sun for a while.
13:38 In fact, it's so cold that there might even be some ice on it.
13:42 Look at the planet's north polar region,
13:44 especially those sunlit yellow spots inside craters.
13:47 These are indications of water ice.
13:50 Turns out water is much more common in space than we thought.
13:54 Mars is often dubbed the "Red Planet."
13:57 It earns this nickname from the abundance of iron oxide, or rust, covering its surface.
14:02 The iron-rich minerals create a rusty red hue that paints the Martian landscape.
14:08 But, it turns out, Mars isn't just red.
14:11 If you were standing on Mars,
14:13 you'd witness desert-like butterscotch terrain with caramel and golden glows,
14:18 some brown, and even a glimpse of a slight greenish hue.
14:22 Mars also has the biggest mountain in the entire Solar System, Olympus Mons,
14:27 standing at a staggering height of about 13.6 miles tall.
14:32 It's even taller than Mount Everest.
14:34 It was formed by the volcanic eruption yielding low-viscosity lava,
14:39 creating a shield-like structure.
14:41 Since Mars is covered in sand, it's also famous for its crazy dust storms.
14:46 But, it turns out, they're even more insane than we thought.
14:49 These storms can last for months.
14:51 While they might present challenges for future human missions,
14:55 they also contribute to the planet's mesmerizing appearance when observed from afar.
15:00 And not only storms, but even its own Marsquakes.
15:04 Also known as seismic tremors, they were first detected by NASA in 2019.
15:09 Unlike earthquakes, that are often triggered by tectonic plate movements,
15:13 Martian quakes are thought to result from the cooling and contracting of the planet's interior.
15:18 It's interesting how similar, yet how different the planets are.
15:22 Saturn's iconic rings might hold a secret link to Earth's ancient past.
15:27 The rings are composed mainly of ice particles and debris,
15:31 and are estimated to be relatively young in space terms,
15:34 perhaps just a few hundred million years old.
15:37 Now, there are some theories that propose that they were born after some catastrophic event.
15:42 For example, the collision of two large moons, or the breakup of a comet.
15:47 What's interesting is that this timeline coincides with the age of the dinosaur's demise on Earth.
15:53 Could there be a connection? Who knows?
15:56 By the way, while Saturn takes the crown for its rings,
16:00 it's not the only planet in our solar system sporting them.
16:03 Jupiter, Uranus, and Neptune all have their own set of rings,
16:07 although they might not be as visible and cool as Saturn's.
16:11 However, there's something where Saturn truly stands out –
16:15 the magnificent hexagon at its north pole.
16:18 It's a colossal six-sided figure.
16:20 Each side of this incredible structure measures around 9,000 miles long,
16:25 which is 1,200 miles longer than the Earth's diameter.
16:29 Scientists aren't sure how it was formed or why.
16:32 They think it might be due to varying wind speeds.
16:35 Or maybe it's shaped by a localized, slow, meandering jet stream.
16:39 So far, it remains another of Saturn's mysteries.
16:43 That's it for today!
