The closest exoplanet to us, Proxima Centauri B has captivated the imaginations of scientists for years. Why? Because it is about the same size as the Earth and it orbits its star within the habitable zone, meaning it could be a world capable of supporting life, and it's right next door! So could this mysterious exoplanet really host alien life? Some scientists think so and they have simulated how.

No sh*t, tell us something new
You earthlings are rediculous. 👽 This planet is nothing like what you earthlings call proxima b. Regards. the aliens. 👽👽👽👽👽
Proxima b is more dead than Mars. It would have tidally locked to its star long ago and it has no way to maintain a magnetic field beyond sharing one from its host star. Simulations show that life could perhaps thrive on _young_ worlds around red dwarf stars. Proxima b is _old._ If life still lives there, it must be more extreme extremophiles than any we've seen on Earth.
There is also the Pre Main Sequence problem with red dwarves.
Long story short, they are hotter when they are forming and cool dpwn when fusion starts. So the habitable zone is wider intially a d wod boil away the oceans on any planets in what ends up being the habitable zone.
@@Pyxis10 and when they get older they become more stable in their increasing the life likelihood we should probably be finding ancient red dwarfs
No one knows if life on proximal b exists we will have to find
@@saviourojukwu893 The universe is only ~14 billion years old. There are orange dwarf stars that old. The Methuselah Star, for example, is a yellow subgiant at ~0.8 solar masses and its estimated age is roughly the age of the universe. It would have been an orange dwarf in its youth, more similar to Toliman than Proxima.
Red Dwarf stars will last far longer than this. But my investigations into the conditions for life seem to suggest that it is far more likely to begin in a young planetary system. If a planet requires many millions of years or more in order to become habitable, then it is probably too late for life to take root by then, unless it was deposited (contaminated) from an outside source (panspermia).
Oh you’ve been there? Otherwise you have no idea
Proxima B has spent the last few billion years being blasted by megaflares, it's almost certainly an airless, dessicated rock.
So not a good holiday destination then.......? Asking for a friend.
@@MadHax-wt5tl You might get a good suntan there. Don't forget to pack the sun cream - factor 1 million. Oh, and a few oxygen tanks might come in handy.
@@paulohagan3309 Doesn't matter now, I've cancelled my tickets.
We just do not know, but if I was to make a bet, I would place my money on your comment.
personally i think europa might have life in its oceans, better chance then titan or Proxima B
Venus is in the Sun's habitable zone, has water vapor detected in its atmosphere, has a rocky surface, and is almost the same mass as Earth.
ok, and? Did you intend on expanding a bit on that thought?
@@user-zv3iy4zo4p "Habitable Zone" is like wild grown edible. Sure you can eat it and it won't kill you, but you're not going to farm it either. If it was good to eat it they'd sell it at the grocery store.
@@user-zv3iy4zo4pI think the implication is all of that and yet Venus is uninhabitable af
@@TheWatcherxx99 Why do you think Venus is uninhabitable? In fact it is more habitable than Mars.
@@user-zv3iy4zo4p i think he would've gotten his point across better with "lifeless" instead of "uninhabitable"
A planet that is half ina perpetual day and the ofher half in a perpetual night. What a great location for an amazing movie! I wonder why I haven`t seen such one yet?
I really hope there is life somewhere in the universe and if it's close to our home, that will be an amazing discovery for all of humanity. Knowing we are not alone in the vast cosmos.
except, we never find them despite people thinking and believing in it.
sure, there might be life out there, but i think they're outside our universe. and by this i dont mean the observable universe only.
@@farhanrejwanThat's not how probability works
There is probably life in Europa...
@@Rapter6969 +
I’m certain there there’s other forms of life in our solar system. Mars, Europa, and Titan look promising.
thanks Rob - always look forward to your videos
Looking for life on a planet close to a red dwarf is basically a waste of time. Stay focused G-Type stars like our sun. I will really get excited when we identify planets in the habitable zone of Sun like stars. Alpha Centauri A probably has planets and would be a more worthwhile target of study.
The problem is, our G, K stars are super rare, and almost every star is a red dwarf . Also, early solar system modeling seems to indicate that our solar system is extremely unusual, and it could be we just got really lucky.(most stars do not have inner rocky planets, protected by one or more Gas giants beyond the ice ring, and in fact most seems to have gas giants within th eorbit of Mercury)
But statistically, life, if it is common in our universe, will be found overwhelmingly in systems of red dwarf stars..
This is just statistical fact.. And it will exist by many orders of magnitude, compared to K, G, or F stars.
This is just a mathematical reality.
I think you are trapping yourself in a box for a "life as we know it scenario" but let me propose this--
In our own solar system, we have 7 or 8 planetary bodies that might currently support life, or at some point in the past, or perhaps at some point in the future-
Venus, Mars, Enceledus, Europa, Titan, Triton, Ganymede, Callisto, Ceres, and Pluto.
I'm sure you can see which type of celestial body, is more common just on our one cherry picked example..
That's right, "tidally locked, frozen planetoids, with hypothetical warm and abyssal, salt water oceans;
It could turn out that life often originates in these types of conditions, under the ice shell of a frozen moon around a gas giant beyond the liquid water belt(protected by its ice shell from solar radiation, comet strikes, extinction events, supernovae, etc...
These moons, are tidally locked to a gas giant, and are made up of mostly silica and water, but thanks to all the tidal forces from the parent planet and multitudes of sister moons, there are always planety of heat energy at the ocean floor, just like the "chimney's"and biosphere found on our own planet in the Mariana trench..
Very excited for NASA's Europa mission launching this year..
Anyway, now lets crank it up a notch.. Instead of a gas giant, lets imagine earth-size frozen worlds, (not only are red dwarfs the most abundant star in the universe, water happens to be the most abundant compound too)
with rocky cores, that are tidally locked to red dwarf stars, in the same way Europa is tidally locked to Jupiter. I mean Jupiter is a failed brown dwarf, amirite? So I think frozen worlds, around red dwarfs, where the life in the oceans are protected from solar flares of young red dwarf star, and like I said, anytihng dangerous pretty much.. I mean life as we know itr, needs water.. So if we find life on Europa, that would indicate, not only is life extremely prevelant, but that the scenario that is most common to life originating, is one of these frozen water worlds.
Well this is my theory of why life will be overwhelmingly found in oceans under ice, in the galaxy, and it will be vcery rare to find a planet like ours. And why looking for rare G, F, or K stars, is a waste of time. Or at least, it would be a mistake, to focus ONLY on our similar star type. (especially when every red dwarf is literally a candidate.
In terms of our solar system being very unique and special, and not all similar to other G type stars astronmers have observed, our gas giants are far out, most stars, the gas giants are inside the orbit of mercury, and the rocky planets are pushed to outer orbits.
If "Thea" hadnt crashed into our planet, and formed the "moon" , without it, we might have ended up exaclty like Venus.
So I would argue that a planet like ours, around a G type star, would NEED to HAve a large moon, and plate tectonics, and even though our telescopes are not really capable yet, we have some idea, and it would indicate that our large moon is very rare.
One last thing, are you aware of the findings of dimethyl sulfide on planet K2-18B?
Almost would have been a point for your theory.. but it dont look good.. here ya go
I was excited for ya, but i just found this-
my/webb-biosignature-gas-k2-18b-12904.html#:~:text=In%202023%2C%20astronomers%20reported%20a,-Earth%20exoplanet%20K2-18b
Well, looks like in 6 months we will know for sure..
@@user-zv3iy4zo4p I hear you and thanks for taking the time to provide such an extensive response. I have no doubt that we will find life on many different worlds (including our own solar system) around many different sun types, after all life seems to find a way, extremophiles here on earth are an example of that . However I was referring to an evolutionary process closer to what we have experienced on earth.
Excellent video! Beautifully explained and illustrated!! 👏👏
Tidally locked, Irradiated, no atmosphere, barren, dark and bleak, hot and cold, lifeless and hostile. that's just how Proxima b is expected to be!
Holy cow! You need to call them and let them know! I mean, who needs the JWST and super computers when you’re available. 😂😂
@@davidking2835 That was just my expectations! I am not eye of the cosmos or something!
Let's hope we both live long enough to see one day they have a technology to see its surface! as far as I know that's not something that JWST is capable of.
Thanks for video upload, all the best to you & please keep humanity updated with your educational/data into the future. 😊
Another great video rob...👏👏💙💙
Awesome videos as always say
I enjoyed the informative video with gratitude.
as usual amazing and informative
Super! Thank you very much!
back at it again with another great video keep up the marvelous job {ROB}
The flares emanating from the star have been shown to be becoming more from the polar regions of the star as I understand it. This would help the situation on the planet, as far as any atmosphere is concerned..
It is extremely foolish to think we are the only life out there with billions of other galaxies out there.
It’s actually not. Statistically the odds are against there being other intelligent life. No matter the odds, the universe is still too vast and indifferent to life. Those odds are not a good bet. Consider what had to happen for 4.5bln years for us to now write a comment on a TH-cam video…🤷🏻♂️
@@damienkilcannonvryceWho said that it had to be intelligent life?
Life evolved on Earth fairly early in its development, even if complex multicellular life didn’t occur until much later, so there could be numerous worlds out there home to alien bacteria that, for the most part, we’d have no way of detecting without going there ourselves
Who cares ?! 🤷🏽♂️🤷🏽♂️🤷🏽♂️🤷🏽♂️🤷🏽♂️🤷🏽♂️
@@user-xu9fm8fu5j We should care, because if we send a bunch of humans out there just to probably get lost and have to settle on the nearest inspected planet close to being exoplanet-like (earth-like).
Speaking of Star Trek we need a Federation star ship to visit places like Proxima B. It's wonderful that we live in a time when we are learning so much about the universe. It is also frustrating that we can't reach any of the places we discover. The distances are just too vast. And it will undoubtedly take centuries before we can even send robotic missions to these places.
Great video. Thank you. You and Rolo have a great weekend. 🇺🇸❤🇬🇧
This would all advance MASSIVELY faster if not for corrupt and greedy politicians and agencies.
I think that research should be at an international level to create an interstellar ship like the Star Trek or a simple ship as Jupiter II .. a Humanidade continua a gastar com GUERRAS e deste jeito as viagens espaciais não chegarão tão longe, o máximo que o ser humano chegará é apenas em Marte , e olhe lá ...
I love this channel
Thank u for ur presentation bro 😊
Awesome Video 😄😄
Awesome brother
it sucks that despite red dwarfs making up at least 3 quarters of all stars (in the milky way anyway) and have a life span longer than all other types of stars combined, scientists see just as little likelihood for life around the common and long living red dwarf stars as the very rare and quickly dying blue stars. let's hope that if we ever get the potential to discover new life, we can also discover that it is indeed possible for red dwarf stars to have planets teeming with life despite the extreme hostile conditions of the star
“You’ll never find life around a red dwarf if you don’t look for it.”
-Me probably
This was amazing to see. 2029 is such a long ways but it won't feel like a long ways once we get there
Perhaps Próxima B, was our home before and it decayed it, and somehow we were sent to our present home 🌎 and here we are, searching for our future place to live…
After a few seconds of debate I am ready to take the trip to ProXima Centauri. Mr. X
Imagine us as a species attempting to get along with other beings when we have not yet figured out how to do it on our own planet/ country/ town/ village/ household.
we been doing it for longer than anyone knows already, but not in a good way
Great video
Realy I like this video so so much
Apologies for any harsh criticism, but I was rather disappointed.
As a huge fan of speculative evolution, from the title I assumed this would be describing what alien life on Proxima Centauri B would be like, at least in *some* level, but instead it was only a description of about the planet itself and what the environment may or may not be like, with little to no information or speculation on how it might shape and influence the development and evolution of life on its surface.
I can't help that everything I hear Proxima Centauri I immediately think of the sci-fi film Event Horizon and needless to say it didn't end well for most of the characters.
Oh my goodness, that movie traumatized me when I was a kid. I should rewatch it:')
@T.J... and that was the heavily edited version too as the film was originally a lot longer and more violent. Sadly most of the footage is long gone.
@@MetroTitanD78 yes, I looked it up again today and i read about that, it's sad it didn't do well when it first came up, maybe they would have kept the footage then.
well that wasnt really Proxima Centauri's fault, we should not have used that type of warp drive that opens up portals to other dimensions including but not limited to, Hell. I reckon, so thats all on us.
@@user-zv3iy4zo4p you are right 😔
Europa is nearer.
@@Nabsolute_
Or Triton ?
@@Nabsolute_
From a video I watched onlv yesterday on Triton, it's a small moon which was captured by Neptune , is a shade bigger than Pluto, orbits around Neptune in a retrograde motion - nearly a perfect circular orbit but counterclockwise to the other moons of Neptune, and of Neptune itself, and prior to its capture, was possibly part of a 'duo system' like Pluto and Charon, but somehow was torn from its partnering moon before being swept up by Neptune's gravitational pull... I don't remember more about Triton (my memory fails me once I absorb so much then 'poof' the rest of the info fades away 'into the ether' as the saying goes!!) 🤔😶🏴🇬🇧♥️🖖
It's a good possibility. As various stars that have passed by our Sun. The interactions between the meetings of other stars over several billions years might have sent some organics to our closest neighbor star. Proxima passes in the Centauri systems "Oort" cloud. It would pick up icy materials over and over again. Even if it's atmosphere is stripped away from solar flares it might gain it again as it travels in such an orbit.
Very interesting
The Reapers think we're the bacteria in their proverbial toilet.
I think a tidally locked planet, although in the goldilocks zone it cannot be considered habitable.
Fascinating
0:22
"Even within our solar system, it is now thought to be a possibility that life could have independently sprouted up in a few different places."
How, exactly did life "sprout up"? It's fascinating how these types of videos never answer that.
I can't wait to go there
This is all speculation. But still awesome 🤩
"You don't say?!" ... We can only speculate until either sending robotic devices there to investigate or somehow, at some future date, send humans to see for ourselves - as unlikely as that may seem to us right now...and even if Proxima B proves unsuitable for it to hold life (its own, or, for us) there are still gazillions (the proper techhy term!!) of other exo-planets out there in our galaxy for us to explore.
We are not capable of imagining life beyond earth, whatever our imagination is, it still adheres to the life we see around us imagining eyes, facial features, arms, wings, legs, tantecles etc. These are all what surrounds us on earth.
It would be amazing if there was actually life there as well 😊 that way one of the most important questions can be answered
Somehow I feel like you would not accept if the answer turned out to be “Yes, we ARE alone in the universe.”
@@ElayzeeDon’t project your hopeless thoughts onto others. Why tf are you even watching this?
O loved this Artificial Intelligency program, very good!
Writer research questions: If Proxima had a yellow sun like ours could it be habitable even though tidally locked? Any theories on what type of lifeforms would occur there on either the light and dark facing?
On the light side would be some very thirsty dark skinned people wearing sunglasses. And on the dark side some albinos with torches.
I don’t think we will physically visit inhabited planets but technology in the future may connect if others use the same technology. I.e if we communicate thru the internet
Good evening notification gang 🤟🏻
V101. I seen the ad and wondered if you're an actual gamer. (I know you gotta do what you gotta do for them ads) anyway, did you play starfield? Whatvyou think of it?
(Sorry if this sounds sarcastic... its really not!)
Love the vids
This is something I'm still debating on, IF Proxima B DOES have alien life living on it, it would be connected to everything about aliens that we've been studying and hearing about here on Earth, but I'm still extremely skeptical about the whole thing, but for once, there's no doubt in my mind that there is a possibility that Proxima B MAY or MAY NOT have alien life living on it
So the Magellan scope will be able to directly image Prox b, but JWST can’t?
Or is it won’t?
We need to harness unlimited energy first.
they finally think then.. life was 10 000 years before like we never seen stop confusing dreams with the universe
I thought tidally-locked planets were dead zones? Plus the red dwarf crop-dusts it with deadly flares on the regular.
I wonder if we will ever get an exoplanet simulator on Quest.
the old place for sure,nibiru
The umbral zone is the only place that could…hard to imagine though 😊
Proxima B is basicly the real mushroom world from sonic
If a ship travels at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 years (7.3 years would pass on Earth) this includes turning the ship around halfway to decelerate. It would achieve about 95% light speed in 1 year. A 10 ton ship would require 10 tons of continuous thrust. This is by far the fastest way we can get to other worlds and the ship would have gravity the whole way.
All that is needed for this is a fission rocket that can put out thrust for long periods and does not consume hydrogen, you can't bring thousands of tons of that with you.
A true fission rocket should consume uranium or plutonium only. They are both jittery atoms that are on the verge of fissioning all by themselves. There should be a way to get them to fission in a linear fashion. What's needed is a controlled, time released nuclear explosion.
In an atomic bomb fission occurs when neutrons hit uranium or plutonium nuclei. This is because they will not tolerate an increase in mass. Due to the equivalence of mass and energy, the same should be true if you infuse them with energy. This might be as simple as having negatively charged uranium or plutonium atoms coming into contact with positively charged uranium or plutonium atoms.
With the constant acceleration method a ship can span the entire diameter of our galaxy in 24 ship/113,000 Earth years. Systems with stars similar to our sun can be reached in under 10 ship years.
Tidally-locked planets are going to have surface temperatures of about 500C on the side facing the star. So, there is no water or ocean on this side. It will have evaporated in the first 50-60 hours on the side facing the star. Then every volatile in its surface that can turn into a gas, does in fact, get baked out and all these gases will also enter the atmosphere. Depending on how it goes afterward, the planet will either be like Mercury or like Venus (Venus being similar to a tidally-locked planet in that its rotation rate is 240 Earth days long).
I have one question. Wouldn't the lack of a day-night sycle be a little problematic if we tried to live on Proxima B?
Roller blinds.
no but the weather and radiation will
Proxima b inhabitants can not lie and communicate thoughts as they occur. We know that they survive times of extreme hardship by dehydrating. We also know that they are militant and prone to fear.
11:30. The JSW can't detect anything about proxima b, because the planet does not transit relative to our view.
That means the planet orbits in a plane, that makes it hidden from direct observations on earth.
The only way to know what proxima b looks like will be through drone/ probe imagery
how?
We keep searching for life as we know it totally ignoring other possibilities
IF it has liquid and IF iy has an atmosphere, considering it's tidally locked, imagine the winds on this thing.
👍Thankyou
Usually with a red dwarf star as the main sequence star the planets in its orbit are tidally locked (they don't rotate). Even if in the habitable zone, it would be difficult for life as we know it there. The illuminated side which always faces the sun would be pretty hot, the backside however would be icy cold (probably like Titan at best). That is not to say that in the farther reaches of the illuminated zones (twilight and sunrise areas) there wouldn't be SOME forms of life. Maybe some primitive, small or microscopic lifeforms, I don't know. I could be wrong but so can scientists. No one is right all the time.
Every space channel always says we found earth like world then when described find out not even close to earth like
That creature looks like the road runner to me.! Y bother to go there? You’d never catch him !😮
Realy I like it its interestyng
It was already documented by the govt project Serpo... Appeal to the govt to announce that in the UN Meeting...
I’ve always thought that with all the stars we can see there must be other planets that are like ours, some more advanced than ours some the same and some just starting, either way we are not the only planet with a life form on it.
Look up the Fermi paradox. We might be the first in the galaxy
Statler: You suppose they have any life on other planets?
Waldorf: What do you care? You don't have any life on this one! Hohoho!
When will we be able to send radio messages to them and get a call back?
Now. It will take 8 1/2 years to get a reply tho
why they only think could be? why they don't know!
The greys are from that star system
I would say that on an Interstellar level that we humans are pretty much neanderthals and thus should be not surprised at all that we as humans do not have the capability of detecting really anything beyond our own couple of feet in front of our own nose
Trisolarans were found I guess.
Chat GPT4 really does help make great videos. For starters you've not mentioned any proof, and for the most part it's all theoretical as in my belief there's no telescope that can reach that far due to its position. You have right about one thing and that's it being tightly locked and about the red dwarf.
But when you mentioned simulations run that was a dead giveaway for AI being used for the help in this video. Really really good video It's good because I'm still watching it lol.
Yes, I did the whole "look at the night sky and wonder if something's looking back thing" - then I learned about the speed of light and just how far away in space and time most other stars were and thus knew the answer was "Not bloody likely."
edit: And planets around Proxima Centauri have been confirmed? Did we have actual visual sightings of them and not just the usual occasional variation in the star's light that we've decided must mean planets?
B and c confirmed by wobbles, d unconfirmed.
Still no direct images. Needs to be moved up in James Webb to do list
My thoughts on alien life in the universe are like my wife's 100% as we both witnessed 1 UFO through binoculars before it shot off so we know that other Life form's exist out there and could be millions if not billions of years in advance of us primitive people who have only been advanced a few hundred years.
How would Proxima B have a strong magnetic field id it is tidally locked?
Ouch, that hurt.
how does this channel have so many subscribers
YES
We're looking at the pictures of planet 4.2 light years ago, do we even know planet still exists?
Good science. Frustration of 4.2 LY.
we must search for life as we know it, in stars like the sun.
The Trisolarans came from there until the entire system was wiped out by another planet in the Dark Forest.
The radiation on the surface would be the equivalent of a nuclear war environment. Life couldn't even begin let alone survive.
Remember how long you’ve been putting this off, how many extensions the gods gave you, and you didn’t use them. At some point you have to recognize what world it is that you belong to; what power rules it and from what source you spring; that there is a limit to the time assigned to you, and if you don’t use it to free yourself it will be gone and will never return.
free yourself for what?
@@MCNarret Think of yourself as dead. You have lived your life. Now, take what's left and live it properly. What doesn't transmit light creates its own darkness.
James Cameron’s Pandora is that you?
I am sure there should be something over there... , such a huge space with trillions of stars and galaxies, we can't be the only living here....
Proxima B probably looks like every dead rock from The Twilight Zone in the 60s.
That place can't be worse than Jacksonville Florida lol
Sirens of Titan, 3 Body Problem. Not too hard to concieve
I think we need a better robot than a metallic-looking flake of plastic if we're going to Proxima B.
Please weigh the pros and cons of a four light year experiment against building many gravity neutral orbital environs, i.e., Lagrange, a much greater increase in population and resource acquisition over next 200 year or so. At the same time, we probe the distance for humans transcendence.
I’m sure life exists throughout the universe but we may never actually find it. The distances are far too great to travel to it. A warp drive could achieve the ability but the energy for a warp drive is astronomical. No pun intended.
I wouldn’t call it right next door bro😂
Does this confirm krypton? What happens when they come to a yellow star system? 😮
