I hear "forty light-years" and start feeling as though that's super-close compared to everything else in the cosmos. Then I remember that the Voyager probes haven't even gotten one _light-day_ away from Earth.
Yeah, it does sound close until you remember just how fast light travels. I doubt humans will ever make it that far away from earth. The best we can probably do is send robots/ai once we can accelerate a ship to a meaningful fraction of the speed of light.
21 light hours away as we speak
@@Axiomatic75 nah the moment we can build space habitats and reliable mine asteroids we could eventually get there (time irrelevant)
@@AmonTheWitchnot many asteroids in interstellar space though 😢
Like the distance btw rent a the 30 period that results in my optimum money obtaining time period based on how much carbon I break down by eating it in said period.. continued…
The moment you said “Super Earth” my brain played the Helldivers theme.
I'm imagining another planet with its own Anton Petrov, who makes a video about the discovery of a distant planet potentially habitable, with water and land, orbiting the star Sol every 365+ days.
Nah, too much poisonous oxygen...
unlikely to be habitable. It orbits so slowly. Its inhabitants will be burnt to a crisp in summer and water truly FREEZES in the winter. Strange oxygen signatures though.
Their days would have a different rotation rotation period but there would be an analog to the idea 😁
"Oxygen. Terrible. Oxygen oxidizes everything. Crap - not a proper planet!
Only this carbon dioxide peak gives any hope."
@@sidharthghoshal Already has been confirmed to be due to strange geological processes. It's an uninhabitable hell hole.
Oddly enough hearing about these potentially habitable worlds makes me appreciate the definitely habitable world we already have. We were grown here to fit the system. Maybe there's a place out there that can house us and maybe there's a place that can do it better, we should totally be looking and if we can make it happen all the better. But there's still going to be only one place we evolved in.
My knees get weak just thinking of the gravity on some of these worlds.
sadly our telescopes can't look at earth sized planets
@@1ycan-eu9jiyes they can
They just can’t look at earth sized planets in earth-like orbits around sun sized stars
Perfect position for your partner to indulge.
@@Timbo6669💀💀💀💀💀
Luckily, life on a water world wouldn't be bothered by high gravity.
Ah damn, it's got cataracts.
😂
We can heal it 😂
Dude. It's a freakin 20°C ocean! That's awesome for swimming and sailing!
@@HanSolo__ Detecting multiple leviathan class lifeforms in the region. Are you certain whatever you're doing is worth it?
lol
no panic, surface gravity is 31,8 m/s² on LHS 1140b. It's really hard to get off Earth with s.g. of 9,8 m/s². So probably they can't leave their planet. The escape velocity must be huge. For those who want to go there: you can check in every time you like but you can never leave lol
No sea eagles then
Scott Manley ran the numbers for a "typical" super-Earth. He figured that a Saturn V could life a small, lightweight satellite into orbit.
@@ianstopher9111 no eagles, but definitely hotel california
The formula for the escape velocity is v = sqrt(2gr), where g is the gravitational acceleration on the surface and r is the radius. So LHS 1140b has around sqrt(6) times the escape velocity on earth. And it also gets easier with more height. So I think that‘s not too high but of course also not that easy.
The surface gravity actually is a lot less (about 18.3 m/s²), the number 31.8 is outdated.
Imagine looking for planets and they stare back at you.
I've always been interested in the idea of a science fiction story set on an eyeball planet that uses the shadow of a moon to run caravans across the scorched side of the planet.
that idea is cool & creative asf
The eyeball is on the sunny side, it's liquid because if always faces the sun. The other side is frozen, how about a giant flying mirror to reflect sunlight, so they could explore the ice.
That sounds like a fire concept! Just imagine how life could adapt to such conditions!
There could be some creatures that go into hybernation until the moon blocks out the scorching sun again. There could be swarms of flying/ jumping, migrating insectoids following the shadow of the moon. Fish that come to the surface when the moon covers the sun and dive back into the depths when it moves on. There could be swarms of flying tartigrade/ plancton-like creatures escaping the heat by flying high above the surface when the sun shines and only coming back down to mate when the moon blocks out the light.
And let's not even get started on the plants! They would probably be much lighter colors like white/ silver (similar to the desert ant) to reflect most of the light. These flowers would bloom during the eclipse when the moon blocks out the sun. There could be entire ecosystems of floating reflective algea/ plants where underneath fish live in the root system and provide important nutrients.
Obviously, your idea needs some more polishing, I think in order to make it work, you would need at least 2 stars to illuminate both sides of the planet constantly.
The ideas here are endless. You could call the book something like "scorching" or "eclipse".
Get to writing already!
@gkw9882 I think he knows that. He was just toying around with the opposite idea.
Scorched? Wasn't the "eyeball" thought to be formed by water on the side facing the red dwarf and the rest frozen over? Anyways, made me think of the prison planet Crematoria in the movie "The Chronicles Of Riddick" Where it is either scolding hot or freezing, with only a small window one is able to move on the surface of the planet.
I would be very interested to see a real picture of one of these places, that would be unreal. Ah well the visuals provided are also pretty good! Great video Anton!
Think of all the artists youd make unemployed. Space news articles always must have one or two artist pictures in them.
Non-Human Intelligences exist. Non-Human Intelligences have been interacting with humanity. This interaction is not even new.
Bruh wants to see a picture of a planet light years away with the same quality as a telescope pointed at earth a few thousand miles away, go invent a gravitational lens based telescope then - that would be unreal.
@@thingonathinginathingproof: “I saw a video of a blurry triangle on Reddit once”
@@mnrvaprjctBreakthrough starshot seems promising. If we wanted to we could do it this century. Unfortunately nobody would fund it tho lol
The universe is just one incredibly large painting. A painting where you can always find a hidden brushstroke technique, or beauty overlooked.
Anton, you’re probably the only person I could ever listen to all day long and not be annoyed.❤
Thanks Anton! 😊❤
I so deeply wish we could have actual photos of exoplanets, other lifeforms or not. It does not even matter. Just seeing vast oceans like we could never imagine would be breathtaking.
I've heard enough. I'm going there.
good luck with that.
Book your ticket early, get a discount - and lots of Airmiles! 😁
Maybe Elon musk will announce a mission there and then cancel it. Dear Eyeball Planet
Godspeed
50 LY is a bit far though 😮
I was thinking to myself, "Hmm, I haven't watched Anton's video today, did he upload yet?" and yes! it was 15 minutes ago!
We love you Anton!
His and his team’s ability do deliver that constantly such high quality content is really impressive. I’d be curious to have a video about what goes behind the curtains of Anton’s team!
I can't imagine how he's able to maintain the pace, but I'm glad he does!
Gotta get our daily dose of Wonderful Anton
Anton, I love that you assume our intelligence. You do not "talk down" to us like most science RUclipsrs do. Dr. Becky, I am looking at you -- with my eyeball!!!
please talk down to me though...
Anton is just the most wonderful person!!
TWO QUESTIONS
1- would the planet have a huge ice wall?
2- would there be huge sweeping winds across the one patch not ice? Which I would then think would make the surface unbearable.
Answer
We have no further information from which to draw conclusions either way.
If the planet was an ocean world, the night side would be more impassable than the Arctic Ocean. Add an Earth-like atmosphere and there would be a massive thermal where its sun would be at the zenith, driving convective wind currents and making the temperature difference less extreme. There could even exist a perpetual storm at that point.
Xrays and other emissions from the red giant strpping the atmosphere, if it had any?
Wonderful as always Anton. Thank you. 😊😎👍
I always enjoy your videos. Thank you for all of the hours of work you obviously put into them to make them interesting and insightful. Big fan!
Thanks! Always interesting and entertaining.
Always amuses me to think of eyeball planet civilisations. They’d 100% believe their world is flat. And their maps would look just like the crazy flat Earth maps do, with ice around the perimeter 😂
Well they’d be aquatic so their maps would be dope regardless
Or they’d send probes or satellites around the planet to figure it out. That requires intelligence though.
Assuming there were intelligent beings on one of those planets similar to human beings, they would probably come to the same conclusion that their planet is a sphere just using ground tests
@@pauloakes6952he said civilization, so I think that the intelligence is kind of a part of the package.
Although I would be still curious if they could develop a cosmic program on an ocean world. Or want to.
😂I hadn’t thought about that. I think their religion and culture would be wild too since their world beyond their “eye” would be uninhabitable and probably unreachable.
However, as the other commenters pointed out I think as long as they could develop scientific methodology they would be able to determine that their world was round. For example, they could look at the angle their sun makes at the same “day” and time in different parts of their “eye”.
Incredibly thourogh & detailed video thank you again as always Anton
Cool work, wonderful Anton.
These videos are one of the highlights of my days. Great stuff Anton!
You are most probably only scientist who speaks the language of us, the non scientists. Thanks for making such a complex subject so enjoyable!
awesome episode! those eyeball artist images looked awesome
So they are seeing us in 1984 waiting for back to the future to come out. I think they’ll like it!!
Big Brother is watching you
At that time, the Olympic Games are played in LA and Reagan is four months away from beating Mondale by a landslide.
Exciting news! Keep looking JWST!
Thank you, Anton!
Life, as we know it on Earth, relies on daily change in temperature and the non-equilibria associated with it. It is hard to imagine that life could be created and maintained in a world that is perpetually locked with its hosting star. The chance for it to have a magnetic field and a magnetosphere is slim.
As long as they stay away from LV-426, we should be ok.
9:12 My knees just get weak.
Basically I am hooked on this channel.
LHS 1140 b has long been a source of fascination to me. Now it's even more so.
Personally I've always preferred LHS 1137 b.
I’m viewing you with my Rocketry: To Infinity and Beyond class. I’m telling them all to subscribe to you, Anton!! 🚀
Correction: If a tidally locked planet is mostly rock, but has enough water
to cover it completely, and is cold enough that said water is frozen, except
in the substellar region, then, in the long run, the result would have to be that:
• The substellar region becomes a desert, surrounded by a massive wall of ice,
ice that is continually melting; thus there should exist permanent rivers and lakes.
• The wall of ice is constantly creeping inward (toward the substellar point),
pushing rock along, like a bulldozer, and this would pile up into mountains,
but running water and creeping ice would carve deep canyons.
• All the evaporating water forms a perennial ring of snowing clouds.
• Around the substellar point, there should be a landscape gradient suitable
for savannah, “lake region,” forest, montane ecosystems, and tundra.
Much depends on the temperature of the dark side of the planet. If it's cold enough to freeze the inert gas in the atmosphere (nitrogen) then there might be little atmosphere at all.
Nice to know about this ,thanks 👍😊
Frozen on the dark side, but not necessarily frozen all the way down. Water ice is a good insulator, & esp if there is internal geological activity or strong tidal forces, there could easily be liquid oceans under the ice on the dark side. It would be a very interesting biosphere if there was one.
Damn cutey. You got a thick atmosphere and an active liquid cycle
How am I supposed to sleep knowing that planet is up there staring at me? 🎯
Thank you Anton
Close enough for us to visit some day -- who can say, one hopes for such a future for humanity
Oh, no! colonizers 😂
Even a single light year would be non-traversible in a lifetime at our current level of technology.
New Anton ❤❤❤🎉🎉🎉
Extremely exciting, very detailed description of this planet...
interesting find!
Aliens who live there would assume their world is flat with an ice wall around it.
Marking my calendar for that 5-year reveal!
Thanks!
I always try to leave a little room for some of the estimated mass of any exoplanet actually being a sizable moon, possibly even a double planet setup, given the measurement sensitivity of the currently existing instruments probably isn't high enough precision to tease that detail out of the data.
Apparently, planets with a massive partner like ours are relatively rare.
@@stevenkies802Dr. David Kipping, Professor of Astrophysics at Columbia (Cool Worlds) won time on the James Webb to look for exo-moons for the very first time.
@@stevenkies802 According to the Giant Impact Theory, our Moon formed by accretion of debris from a Mars-size planetesimal (named Theia) colliding with the primordial Earth.
thank you wonderfull person
Hello wonderful Anton, this is Person
So an eyeball frozen water world, that's interesting. I'm imagining a world that's probably not this one but just a bit hotter where the water on the closest part where the melted patch is evaporates away. Then the water vapor is caried to the far side and falls as snow that builds massive ice sheets until nearly all the water is ice on the far side and the near side is a desert. But the mass of the ice on the far side pushes glaciers toward the hot side all around the planet. And the glaciers melt into rivers that flow into the desert and dissappear into the sand but with greenery on their banks.
This is great Anton. A tidally locked planet with in the Goldie locks zone with liquid H2O with in a hot spot. Great 👍🏻
Cool!
Very interesting
I find it ironic that an ocean world would be seen as habitable, for humans at least, when trying to live on Earths oceans is hard enough.
It’s about how life evolves in warm water, and where there is movement to coax the primordial oozes. Yes, when we get to our level, we couldn’t live there. But that’s where we started
@@AnthOny-gl7ljWell, yeah, but that's here on earth. On an ocean world like this the oceans would be tens of miles deep in the shallow areas. There'd be no continents like here, hence the name ocean world. Water makes up roughly 0.023% of earth's mass. With an ocean world that's roughly 20 to 50% of the mass.
very cool
tyvm
It would certainly be an interesting world to study up close. Being that large it's more likely to have held onto some atmosphere, and a magnetic core could be possible. It also may not have had active plate tectonics like our planet if it ever did, since a similar moon to ours is highly unlikely to stick around if it even forms. Any water would mean it has some interesting chemistry on the surface, especially if it isn't alive and the planet is as earthlike as it currently seems.
It kind of sounds like darwin IV being so close, and considering everything else.
If we find a reachable habitable planet i will volunteer for the first generation if a generation ship.
As soon as the ship is out of reach of earth we will create a better path for humanity, that actually works and will survive and have an inspiring future.
I'll join you.
Id observe local life forms.
Since this planet is likely tidally locked and likely has a warm and cold side, I wonder if there is some kind of air circulation and ocean current which moves the warm air and water around the planet, which could make certain regions of the planet even more temperate.
This looks like a perfect planet on which to orchestrate a Second Impact
Red Dwaves are thought to last longer than our Sun.. So worlds surrounding these stars if habitable would be great long term for human life.
Anton: Another exoplanet with possible life!😊
Can't wait for the alcubierre warp drive update to drop already so we can go explore these new maps!
Man, if some sort of technology can actually get us to other worlds. I'd immediately buy myself a brand new ufo & be like "Peace out, Earth. It's been fun, but I'm never coming back."
And then proceed to visit every world in the neighborhood. Yep, a total planet-slut. That's what I am. When do I get my Pride Month? 🤣
Cool, all we need now is near light speed travel.... and we can go see for ourselves what it is. Thanks Anton!
40 light years even at nearly c would take more than that amount of time to get there. We'll need to come up with warp drives or traversible wormholes to get there in a reasonable amount of time.
@@JamesDavy2009No problem. Let me just grab my ufo & we can head over.
@@adammaturin1277 It's unlikely to be the same planet when we do get there. From Earth, we're seeing it as it was 40 years ago.
@JamesDavy2009 Yeah, when we get there, I imagine you're going to sigh & say, "The old girl really has changed, hasn't she?"
With a tear in your eye and a quiver in your voice and all that sappy stuff. 🤣
@JamesDavy2009 Ugh, I'm so tired of RUclips breaking my links so people don't see I replied. 😤🤦♂️
What a golden age for exoplanet research. Crazy to think that 15 years ago, the total number of discovered exoplanets was something like 10 ...
And a century ago, we barely accepted galaxies outside The Milky Way and quantum mechanics was in its infancy.
Very interesting, lots of ifsnbutz but very interesting. Should have built 2 JWST we would have twice as many, of Anton's great videos 😄.
Very interesting, thank you again.
Ordinarily when I hear of planets around red dwarfs that 'may be suitable for life' I automatically think "ah, no." Tidally locked planets close-in to such 'flare stars' will be at very best barren rocks...
...but an 'ice-shell world' with or without an 'eye' with an abundance of water may be in a better position than most to be technically habitable. I hope now or in the near future we will have the ability to check such bodies in greater detail.*
*My gut tells me the solar system is an island with life in a very large and barren universe. Indeed, it's very likely that even here only Earth has life. But that's no reason not to look, and I'd be happy to be proven wrong.
This looks extremely promising to my eye 🤔👁️
If we can get Breakthrough Starshot tech to be common place, perhaps launched from the moon, we would learn so much more about the cosmos. It would be great if LHS 1140b had rotation, and land. Trappist and LHS are basically 40 light years away- not terribly far given cosmic distances. Thanks Anton.
At breakthrough starshot’s top speed, it’d take 200 years to get a probe to TRAPPIST-1.
Not terribly far on a cosmic scale doesn’t mean much.
Thanks for giving the distance to the system, I missed it in the video.
The video is not about trappist system
@@Poske_Ygo Good observation. Very true.
@@oberonpanopticon200 years is pretty brief for an interstellar mission, surely?
I'm naming my kid LHS 1140 b 🙏
I apologize for the correction, however, I think you mean Permanent-Temperate, not Permanent-Temorary like I heard you say. The latter statement is opposites in definition in english language. On a side note, very interesting information my friend. Keep up the good work.
Temporate - what our planet is. Temporary - only short term.
If there is any life on that world, it will likely be fairly deep in the ocean due to the fact that it orbits a red dwarf. Red dwarfs tend to be very variable stars despite how relatively cool they are and can pump out a lot of radiation and flares with no warning and quite often. Any life on that world would have to adapt to that if it wants to survive and thrive. And even if life does or can exist on that world, that doesn't mean that it is habitable for us.
Its so beautiful, imagine all the primitive species like us out there, looking to the skies with wonder
To a civilization on an eyeball planet, there would essentially be a scientifically verifiable center of the world. At the very least, a center of the habitable world
I would like to take a trip in my own spaceship to some of these worlds just to take a break from this one, at least for a day. I guess this is as close as I'll get!
we might have to adopt a prime directive when it comes time to visiting worlds with possiable lifeforms....
Thats heavy Doc
"There's that word again: heavy." -Dr Emmett Brown
and this is in our galactic neighborhood. amazing, maybe life isn't as uniq as we think, but intelligent lifeforms like us are very uniq.
I honestly dont care too too much about life on other planets. Or rather that takes a backseat to Earth-like planets. Yes it would be interesting to biologists, the different forms of cells that can create life. But to me, the important thing we should be looking for is Earth v2. We need a back-up planet, or two.
But we haven’t even figured out how to reduce the impact of radiation in space and with earth so polluted, we have way more chances of developing aggressive cancers when traveling
@@LegendoftheGalacticHero they do know how to block radiation. 1 meter of water will block it, which we need to bring anyway. Other materials require less width.
Going there is going to be near impossible, especially for the entire population of the earth
@cybergornstartrooper2157 I don't want entire population to go, we need to have more than one planet so we don't get killed off by some random gamma ray burst, or whatever. But we do need a bunch of people for genetic diversity so I think freezing people has to be developed.
Four. At least.
With a warm side, liquid, and atmosphere. There should be a wind on the planet. The wind direction might be able to be roughed out if it's known it's orbit and if it has a slight different season because. Then at that, it might not look an eyeball. It might look more a sideways heart shape area on it. If the wind due to the forces that be still make the wind decide to travel around the planet in one direction. Icebergs on one side might then break off do to the circulation of the warm air. Then melt away and the warm air current then might create an inlet opposite to.
Life is very adaptable there only needs to be a small oasis where life is possible and from there evolution will take its course...
... Antonomers have observed a shadow on the upper west side of Petrovius, speculating that it is the shadow of the satellite Mike-Boom cast by the star Studio Light ...
It's not habitable if gravity is too high. According to research by American Association of Physics Teachers, 4G is the highest humans could survive, but since nobody has ever tried to live in that kind of pressure we don't really know that they could. Living day-to-day in high gravity might have unexpected consequences on our biology.
you didn't mention eccentricity. With a lot of eccentricity, it will have significant libation. This would make for about a monthly seasonal change, around the edge. Interesting to think about.
You also didn't mention the orbital ratios of it and the other large planet. If it is some nice fractional ratio, it is likely that the eye planet would have a significant elliptical orbit. This would enhance any libation.
In terms of life this warm and freezing planet(presuming no volcanism/tectonics)the evolution/diversion's of warm bodied/blooded creature's extendeding from the iris comes up,and so perhaps biological traces in spectroscopy, and further from that undetectable tecknological evolution of industrial heating beyond the iris that could also be detectable through spectroscopy above the ice in the atmosphere
It's possible, bearing in mind we're seeing this planet as it was when President Reagan was running for re-election.
uuuh that is cool!
People read that something is only 40 light years distant and think thats right next door. and while it may be near by in galactic terms, the fastest thing humans have put into space, would take 64000 earth years to travel that far. voyager1 would take over 700000 earth years to arrive at the giant eyeball.
Most planets that are habitable as less likely to detect
Does a larger earth-like planet increase or decrease the odds of plate tectonics, which seems to be important.
Why don't most of the planets that we find spin or they spend very slowly compared to Earth
Sounds like a DnD setting for me to map out.
Even though red dwarfs are knows for their quite violent behaviour, few kilometers of water shield could protect life in oceans
If this planet does have a large surface ocean even if the mantle is tidally locked the ocean could still carry heat around the planet allowing for a much larger global ocean and more varied climate than the "eye-ball" model.
Anyway of measuring the atmospheric pressure?
its hard for me to believe, with all thats been discovered over the years, that earth was the only lucky one to have life present. i hope im alive when they finally have proof of life on another planet, and if that happens, this will be the channel ill go to hear about the discoveries. keep up the good work buddy and god bless!
What's fascinating is seeing the density meaning it likely was originally was a mini neptune, which had most of it's atmosphere blown off, to the point it's mostly earth like, and ALSO has 2.34x Earth Gravity which means it'll be life bearing but very different.. except in water which can handle the far higher gravity much easier.
And humans can handle 2.34x Earth Gravity, provided we're not disabled, it's just a bit hard on the body, like we're working out constantly. There was a study by NASA many years ago on mice in a centrifuge long term and they could do things without negative consequence at up to 2.5x Earth Gravity.
Also, this is 100% a "gravity trap" planet, meaning that if humans (or our machines) were to land using any known form of technology, we could NEVER leave it. Tyranny of the rocket equation. It's too dense for any rocket using any known chemical propellant, of any mass to escape it.
Use the Tsiolkovsky rocket equation. The ratio required would be 148:1 and the best ever achieved is 20:1. It coud be 1000 stories tall, all propellant, and we'd still never make it to orbit that we could break out and leave.
Edit: Nuclear Thermal Propulsion could theoretically do it but it would need to be 10-15x the size of the Saturn V and would emit a sizable amount of radiation doing it.
Eyeball planets seem to be more varied and more interesting than we previously thought. We should be very careful about making blanket assumptions about planetary systems and their possibilities for generating life when we know so little about them.
