Take a Virtual Reality tour of six REAL exoplanets (4K, 360° VR experience) | We The Curious

Come in… Hello? Is anyone there? Can you read me? Ah! There you are. Beautiful, isn’t she?
The Milky Way Galaxy. And to think, each one of those hundred billion stars has it’s own planets, it’s own strange worlds. Imagine what it would be like to visit some of those exoplanets beyond our own little solar system. Well today, you don’t have to imagine, because I’m going to take you
on a tour of six real exoplanets. What you’re about to see is based on the latest scientific research; and as we travel across the cosmos, we’ll hear astrophysicists from the University of Exeter tell us about their search for planets
beyond our solar system. So, if you want to experience what it might be like to stand on another planet, I highly recommend strapping on a VR headset and a pair of headphones to
feel truly immersed. Feel free to pause the video here whilst you get what you need to start your journey. Okay, are you ready? Let’s go! I’m Elisabeth, I’m studying observations of debris disks and trying to find debris disks and giant planets. So, the planets will form over maybe four or five million years as the star forms. So the star forms
out of a massive cloud of dust and gas and that collapses down and the center
of that will fall inwards and become a star. But then there’ll be a whole cloud
of dust and gas and stuff left and that kind of collapses down into a disk that’s just made out of kind of the leftovers from the star formation. And that disk, the individual bits of dust, will collide to each other and they can sometimes stick together. We don’t really understand that yet. Sometimes they stick and sometimes they bounce off. and no one And no-one really knows how they can stick together enough to start to form a planet. But then as soon as you have a big core,
we call it a ‘planetesimal’. So it’s maybe ten kilometers across, that’s big enough
that it’s gravity starts to scoop up all of the rest of the nearby stuff and then
it kind of slowly picks up more and more bits of dust and gas and they fall down
onto the surface and eventually it grows into something like Jupiter or even
bigger than Jupiter. I’m Professor David Sing, and I study
transiting exoplanets and their atmospheres. Well, Hot Jupiters are gas
giant exoplanets, but they orbit much much closer to its star than Jupiter
does to our own Sun. and crack the orbits In fact, they orbit so close that the dayside of the planets are heated up to thousands of degrees Kelvin. And because they’re so hot a lot of the atmosphere around the planet actually evapourates off. Sort of like when a comet gets too close to the Sun, you see a lot of evaporation of the comet happen, a similar process happens for these planets; they orbit so close, a lot of the atmosphere
is being blown off Because these planets are so close, we
expect them to be tidally-locked, which means the same part of the planet will
always face the Sun. And what that does is set up a very large day/night
contrast in temperature It’s very hot on the day side, and it’ll be quite a bit
colder on the night side. And this will in turn create large-scale weather
patterns around the planet. This planet is so close that the tidal gravity is
starting to distort the planet itself. If this particular planet was any closer, it
could actually break apart but what But what might it look like inside the atmosphere
of one of these extreme gas giant exoplanets? Let’s find out. My name is Steph Lines, I’m an exo-nephologist, which is someone who studies clouds on
extrasolar planets. So what we’re looking at is planet Osiris, otherwise known as HD209458b, and these are extremely strong winds, going from
the west to the east of the planet, from the date of the night side, the wind
speeds are reaching about five kilometers per second; which is about ten times faster than concorde. Osiris has a temperature of around a thousand degrees centigrade, with these temperature ranges we’re not really looking at water clouds
like we have here on Earth. But at these much higher temperatures, we have the
sort of evaporation and condensation cycle of things like iron and silicates. So these planets might actually have molten iron rain, and silicate or glass
rain. Which is incredible, because with these wind speeds of five kilometers per
second, you’re effectively going to be lacerated by this glass rain and molten iron. So these aren’t particularly great places to visit My name is Nathan Mayne, and I study the atmospheres of planets we’ve discovered around distant stars Our next destination is the surface of a water world. This is a ‘Super Earth’, as it’s called.
In our own solar system we have no planets which exist in the size range
between Earth and Neptune. But actually, as we observe off into the galaxy, we
find this is one of the most common form of planets. We think that many of these have kind-of rocky cores. They’re terrestrial planets essentially, but they’re likely to have a huge ocean. Now they’re Super Earths, they’re much larger than Earth, they might have much stronger gravity. And they probably have much thicker atmospheres. That means, any land features that are on these planets, any rocky features, are going to be weathered and suppressed and effectively destroyed. As you can see, the surface is being
distorted by huge waves. There’s many reasons that could cause these waves: you have an ocean which is not interrupted by land masses, So many of these planets we expect could have moons or multiple moons even, which create the same tidal effects that their own moon causes in
our oceans on Earth. Additionally, actually, many of these objects might be
undergoing significant tectonic activity beneath the surface of the ocean, and
these waves have no landmass to crash into. So they really can build to quite
substantial sizes Our next destination is the surface of 55 Cancri e. This planet orbits so close to its central star it’s incredibly hot. We think temperatures of a few thousand Kelvin, or few thousand degrees. We know from how much this planet wobbles it’s star, due to the gravitational interaction, that this planet is about eight times the mass of the Earth. And we also know from it’s sort of transit, when it eclipses the central star, that it’s
probably about twice the diameter of Earth. So this planet is incredibly hot
and has a very strong gravitational field. So what you can see is a molten lava field underneath you, where the surface has been disrupted and melted. And much of that material potentially be lofted into the
atmosphere and what you end up with is a very soot-laden atmosphere, full of
particulate matter, molten rock, and condensing rock and raining sort-of silicate
particles. And you’re going to have huge amounts of charged material flowing in
the atmosphere, and that will lead us to have significant thunder storms. So, effectively, this is a pretty nasty place. Probably as close to Dante’s Inferno as you can imagine; with a molten lava surface, raining block,
and constant planet-wide lightning-storms. My name is Jessica Spake and I’m interested
in studying exoplanet atmospheres. TRAPPIST 1e is a fascinating system. It was a wonderful surprise to find seven
fairly Earth-sized planets so closely spaced together around this tiny star. The star is actually about the size of Jupiter. It’s really like a solar system
in miniature. So here you can see the star’s a lot cooler redder and smaller. You can see it looks very big in the sky here That’s not because the star is bigger, that’s because the planet is a lot closer to that star than we are to the Sun, So, these planets can be very close in and still be kind of about the same temperature as Earth. We have discovered over 3,000 exoplanets, but we’ve only searched less than one millionth of a percent of our galaxy. There are billions more worlds out there for us to find in the Milky Way, and billions more galaxies beyond our own. Each new planet we discover changes how we view the universe and our place within it. But, so far, we’ve only found
one planet Earth. Thank you to everyone who helped to make this video possible. If you enjoyed it, please share, subscribe,

  1. My friend: What did you do yesterday?
    Me: Oh, nothing…just saw multiple planets in my living room.
    Edit: I like my own comments cuz nobody likes em 😿

  2. thing is everyone is excited to know if there's any form of life besides us in the universe and to meet them, but we can't even get along with ourselves in the first place

  3. Аяк такое видео делать 360 градусов

  4. Hello! Please watch this video on my channel … what is a star? or is it a planet? https://youtu.be/YnVQv4DCxCg

  5. I'm quite skeptical of the proposition that scientific models of things that have never been observed are much more than fanciful guesses, but I found this very enjoyable. It illustrates a range of possibilities or probabilities that are inductive of further imaginative contemplation.
    But I would urge the audience to bear in mind that these aren't depictions of what scientists know, but rather of what they reasonably think. Their guesses are a lot better than mere imagination; they are based on a lot of data and careful reasoning. They have stronger claims to truth. But history tells us that the most careful, data-driven reasoning, still turns out to be at least partially incorrect almost all the time. And not infrequently wholly incorrect.
    Scientists generally know this, but they don't like to mention it too loudly or too often, because it's harder to get humanity and their institutions to fund science in general and grants in particular for 'educated-guess' work. I'm not against the funding; I think it's important. I just like to push back against the side-effect of the fettering of imaginations, by the incorrect notion that what's out there is certainly known. We don't even know about here and about ourselves. We just have a working model that is in constant flux.
    A lot is being inferred from the observation of specs of light that dim periodically. The reasoning is sound. But who knows what causes might produce such an observational effect, that we've simply not thought of yet?
    Do not believe that you live in a world – or a universe – that is all figured out.
