Our Next Home May Be Near Saturn or 10 Other Planets

0:00We've been focusing on trying to find life on Mars so much, while there is this gem waiting to be explored. This planet is the sixth farthest from the sun and the second largest in the solar system. You'll find it right behind Jupiter. I'm talking about Saturn, or as they sometimes call it the jewel of the solar system. It's so different from our planet. First of all, you wouldn't be able to stand there. While Earth consists of rock and other tough stuff, this planet is like a giant ball, mostly made of gases. If you found a swimming pool huge enough to fit Saturn, you could see the planet floating in the water. No wonder Saturn is the least dense planet in the solar system. It also contains a lot of helium. You know, the gas you put in balloons to make them hover in the air. Saturn is a very windy planet. Winds there are more than four times stronger than the ones we have on Earth. A day over there lasts 10 hours and 14 minutes because Saturn spins on its axis pretty fast. But the planet takes its time while going around the sun. A year there equals 29 Earth years.

1:05Saturn's radius is more than 36,000 miles. It means the gas giant is 9 times wider than our planet. If Earth was the size of a nickel, Saturn would be as big as a volleyball. Even though some of our planets in our solar system also have rings, Saturn's are the most spectacular ones. You can even see its rings from Earth. And no, you don't have to be a scientist with insanely expensive equipment. All you need is a small telescope. Saturn's rings are not firm. They are made of pieces of dust, rock, and ice. Some of them are as small as grains of sand and some as big as a house or even a mountain. These are actually bits of asteroids, comets, and shattered moons that fell apart before reaching Saturn. They could be torn into pieces by the planet's powerful gravitational pull. Saturn has over 50 moons. And recently, scientists have discovered some unusual hydrothermal activity on one of them. In celadus, it's Saturn's sixth biggest moon. It has four tiger stripes close to one of its poles.

2:05Researchers have found that there is an ocean underneath these stripes. Water and ice erupt from that area. So now, we can't but wonder. Maybe there's life out there. In the oceans on Earth, some forms of life gather around soon. And now, members can earn four times the points on an eligible purchase. Start spring off strong with these deals and more.

3:06They feed on the chemicals there, same as plants on the surface do with sunlight. And not only that. Some of the oldest microbial life on our planet. Feed on the same energy as the one produced beneath the ocean's surface on Enceladus. It could potentially mean there's life developing there right now. Of course, it takes millions and millions of years for even the simplest organisms to appear. But hopefully, scientists will need less time to find more complex forms of life. There are millions of exoplanets out there in space. And scientists have been searching for those that could be potentially habitable. Exoplanets are planets orbiting a star outside of our solar system. Dwarf stars are similar, less luminous than the sun. They sometimes live for more than 10 billion years. That's enough time for a living organism to develop and evolve into a more complex form. Life might appear on the planet's orbiting such dwarf stars, or, like with Saturn, on one of their moons. And here it is. Glease 876B that orbits the red dwarf star Glease 876.

4:10This planet is mostly a mystery. But scientists assume this is a gas giant that has no solid surface. They believe its atmosphere doesn't have clouds. But there might be water in its liquid form on the planet's surface. T. Gardens B orbits a red dwarf that's around 12 light years away from our solar system. The planet's mass is just a bit higher than that of Earth. Scientists think it may have a rocky surface. The planet needs around five days to complete its orbit. It means that one year on T. Gardens B is actually shorter than one week on Earth. Somewhere far, far away. There's another potentially habitable planet named Kepler 1638B. Okay, to be more precise, it's 3,000 light years away from Earth in the constellation's sickness. This planet is four times as heavy as Earth and twice as wide. It needs almost 260 days to complete one orbit around its star. The gravity on this planet is stronger than that on Earth. It wouldn't be an easy feat to jump on its surface.

5:10One more Kepler coming along. This time, it's Kepler 62E, a planet that's more than one and a half times the size of Earth. Scientists believe this one has a warm, humid, and hospitable atmosphere with cloudy skies. There are 1,200 light years between Earth and this planet. Kepler 62E needs 122 days to orbit its red dwarf star. Its neighbor, Kepler 62F, is another potentially habitable zone. It's a world around 40% bigger than Earth. Scientists think this planet might be covered in water. The oceans on our planet are full of interesting creatures and organisms of all sizes. So the chances are this planet also hides some intriguing living beings, or at least it has the potential to develop life. When we say habitable, it doesn't mean life definitely exists there. It just means there are conditions for some forms of life to develop. LHS 1140B is a planet located in one of the potentially habitable zones.

6:10Unlike its gas companions, it's solid and quite rocky. The planet's radius is 60% larger than that of Earth, and its mass is 7 times bigger. It's one of the densest planets found out there. Since the planet has a big mass, an atmosphere there must be rather thick. Plus, gravity on its surface is much stronger than here on Earth. On December 12th, Disney Plus invites you to go behind the scenes with Taylor Swift in an exclusive 6 episode docuseries. I wanted to give something to the fans that they didn't expect. The only thing left is to close the book. The end of an era. And, don't miss Taylor Swift, the era's tour. The final show featuring for the first time a torture poet's department. Streaming December 12th, only on Disney Plus. That's why you would likely have problems just standing on that planet. Hello and greetings from Trappist 1, an ultra-cool dwarf in the constellation Aquarius.

7:10It's around 39 light years away from us. Seven Earth-sized rocky planets are orbiting in the star's habitable zone. All of them can potentially have some water on their surfaces. The temperature on these planets is more or less similar to that on Earth. On the Moon, gravity is only 16% of what we have on our home planet. That's why the astronauts could hardly control their movements when they visited our natural satellite. But when it comes to the gravity on Trappist 1 planets, you would probably feel good and comfortable there. And Kepler, once again, this time it's Kepler 452b. It's a rocky planet 60% larger than Earth. Its parent star is similar to our Sun. This planet has actually spent around 6 billion years in the habitable zone, while Earth has been there for a mere 4.5 billion years. This planet needs 385 days to orbit Kepler 452. This star is around 20% brighter than our Sun, but has the same temperature.

8:10The whole system is very far from our little oasis. It would take you 28 million years to get there. And now, how about KOI-7711.01? It's another intriguing world, 1,700 light years away from us. This planet is only 30% bigger than Earth. It gets almost the same amount of heat as we receive from our Sun. Sometime in the future, people might start colonizing the galaxy. They would be looking for new planets to live on. Then we'd certainly have to make really long trips. And maybe one day, we'd reach Proxima Centauri. It's a nearby star that has a couple of planets we could potentially inhabit, like Proxima Centauri B. It's around 4 light years away from Earth. And it doesn't sound that far at first, but it actually is. It would take about 6,300 years to travel there, if we use the technologies that are available these days. It would mean many, many generations to make a trip like that. And it would take even longer to finally inhabit that new world.

9:10People would be born and raised on spaceships. They would live their lives there without ever seeing either Earth or the planet they're heading to. Instead of trees, mountains and rivers, there would be only the dark nothingness of faraway galaxies spreading in front of them. They would never be able to wander unknown streets. Breathe in the fresh air, feel the wind. The only place for them to travel to would be another part of the ship. Certainly, such a journey wouldn't be simple, but it would pay off if people managed to build some more beautiful worlds, like the one we have here on Earth. Is that even possible? Time will tell.
