- James Webb Telescope Discovers Signs of Life on K2-18b, 120 Lightyears Away... but there's a problem. A recent investigation conducted using NASA's James Webb Space Telescope on K2-18b, an exoplanet with a mass 8.6 times that of Earth, has uncovered the presence of carbon-based molecules, including methane and carbon dioxide.
This discovery made by Webb, contributes to recent studies that suggest K2-18b might be classified as a Hycean exoplanet, one potentially featuring a hydrogen-rich atmosphere, and a surface covered by a water ocean.
K2 18 b orbits a cool dwarf star called K2-18, located in the habitable zone and situated 120 light-years away from Earth in the Leo constellation.
The presence of methane and carbon dioxide, along with the scarcity of ammonia, lends support to the hypothesis that K2-18b, could potentially have a water ocean beneath a hydrogen-rich atmosphere.
The initial observations by Webb also hinted at the possibility of detecting a molecule, known as dimethyl sulphide. On Earth, DMS is only produced by living organisms, with the majority of it being emitted by phytoplankton in marine environments.

Must contact them, they could be saving 15% or more on car insurance
😂😂😂
😂
That's a shallow way of thinking since that's not even an important factor of human life on Earth. If anything, an out of space assistance in curing cancer, Alzheimer's and all dementia forms would be a more life-changing discovery.
ROFL 😂😂
Lol - thank you for that!
So how long before the United States starts sending them money ?
😂😂😂😂
But 1st they will send them bombs
Spread freedom across the galaxy they shall. 🚀
Oh wait loan them cash loan you mean except they'll take the cash and never return are calls
It was a Professor from Cambridge University that discovered this!
…and they never mention or cite him, it a shame.
I think it because his work is still being studied and peered reviewed. There are more recent videos with the physicist.
GOOD FOR HIM. . WHAT HAS HE DISCOVERED LATELY ?
Bcoz he is Indian prof. Madhusudan 😊@@billtev9846
@@RichardKuivila1947lmao Wth dude
Let’s also remember we are seeing the past….
only 126 years ( take 40-60 years) in the past.
The lens of the of the JWT transcends some distance does it not??
Distance doesn't matter. Just knowing that there is life out there will be sufficient to rock this planet of ours and its muddy thinking populous.
It ain’t gonna rock the flat earthers 😅
@@El...Presidente On an epic tangent ... it isn't going to rock those who currently derive their satisfaction in Physics from CMB data, even though it causes so much tension :-).
@@El...Presidentethose people will just deny deny deny. Cause oh apparently nasa lies or something
Well yeah. Also the fact that whatever we pick up happened 120 lights years ago. That planet could probably not even be in existence right now
U misunderstand, what we see now happend 124 yrs ago only, so its probably much the same.
I found it odd that Starbucks had already opened a store there… ☕️
And a Jalisco Mexican Resturant
Also, a credit union.
Also a Burger King and a Walmart
I love it that everyone is adding businesses. 😂
Are the prices as expensive as here?
Why do so many comments here complain K2-18b is too far to visit? We don't want to visit it, we want to study it, which we can already do.
No study Wanna Visit 😂
Speak for yourself
And if they’re more advanced than us… they’ve been studying us for years, scary thought lol
The closest star is too far to visit
Of course we want to visit it!
to Study and LIVE on it.
Meanwhile K2 - 18b planet PEOPLE reporting C2 - Earth XYX might have enormous ocean.
The scientist who discovered this is Prof. Nikku Madhusudhan. (Spelled Ma-du-su-dan) from Cambridge University.
thank you!
'Only' 124 LY's from Earth. With our current technology it might as well be the far side of the Universe......
Doesn’t matter, we shouldn’t think like that we have to reach there physically now, if it’s habitable and we can send other intelligent species and with technology that lasts at least 2000 years. AI could be one of the answer. We shouldn’t think that 125 light years as an obstacle.
@@arifulhaq1199 Way to miss the point. To emphasize that point, with or current propulsion technology, it will take us over 2 million years to get there.....Yeah, not an 'obstacle' at all..... 🙄
JWST supposedly has a computer system designed in 1998, this thing JWST is a fuqin' fake.
@@Raul_Gajadhar You don’t need the latest tech for optics, and there’s a good reason older tech is used in space probes.
There's a "far side"? In reference to where?
Is interesting how the feeling of lonliness we share moves the desire to finding someone else.
And yet we still can't discover intelligent life on Earth 😂
😂
Doesn't matter...still to far away, we will never be able to go there
Why the aliens won't come here, they are watching us from home.
They won’t come because they didn’t detect intelligent life 😫
It blows me away how they can observe these things from so far away.
We're still in our infancy of investigating planets. I think when examining an "ocean world" in the future, finding no life will be a much more surprising and perplexing conclusion than finding life.
I wonder if there will be a new telescope developed to look more closely at an exoplanet, possibly to detect what kind of surface it has.
We’ve discovered the planet where aliens come visit us from 😂 .. we only see 120ly back though so they’re probably way more advanced now
We see the light from 120ly ago. You don’t just look at earth from that distance and see dinosaurs then zoom in a bit more and see the cavemen then a bit more and see us now. That isn’t how it works even with a basic understanding, or common sense.
Where is BUZZ when you need him!? We need to brief Star Command on this!!
Kevin Costner is the Earth's expert on Waterworlds. Ask him. 🤔
Lol 😂
lol thank you, you made my day.
Wow!
Need to build space craft that doesn't require fuel
Professor Nikku Madhusudhan is the person that discovered the possiblity of life on K2-18b. He is British and works at Cambrigde university England.
He is Indian and a Hindu(Sanatani)😅
@@The0ne357 A British citizen is either: a British citizen 'otherwise than by descent' (meaning they acquired citizenship in their own right such as through naturalisation or birth in the UK), or a British citizen 'by descent' (meaning their eligibility for citizenship derives from their ancestors' nationality status)
Professor Nikku Madhusudhan is a British citizen as he acquired his citizenship via naturalisation & Hinduism is his religion not his nationality.
@@EdwardThatch-ee7yx even if he has acquired british citizenship that doesn't take away his indian identity and roots. We Indians always remain connected to our root, Citizenship can be changed as circumstances demand but roots never change they form the identity. His Indianness never leaves him.
@@The0ne357 I understand that. I myself am of Indo/Mauritian heritage but I’m British because I was born in Britain. My parents are British too but they weren’t born in the U.K. This doesn’t mean we aren’t of Indo/Mauritian heritage but it does mean we are not Indian or Mauritian citizens but of British citizenship. And religion has NOTHING to do with anything!
@@EdwardThatch-ee7yx Then why emphasize his citizenship that 'He is British'? Was it your insecurity about the identity of an achiever even though he is working in UK that others may claim credit of his achievements by emphasizing his belongingness and identity.
It wasn't the James Webb telescope that discovered it 🤨 It was a British Astrophysist and then asked if the James Webb could take more pics to corroborate his findings.
Looks like the firmament broke though. Hope the animals survived the flood.
AND WE STILL DON'T KNOW AND HAVE THE TECHNOLOGIES TO INSPECT OUR OWN EARTH...
2.5x gravity, so the aliens will be short and muscle packed.
yeah when they come to earth the can jump like John Carter :)
They be so smol I be laughing and crushing them
It absurd to say " only".
In scale, if our sun was as big as a pingpong ball, earth would be about a meter away, smal as a grain of sand.
Our closest neighbour, Alpha Centauri would be about 200km from that little pingpong ball.....
INTERESTING.
ABSOLUTEMENT.
YEP.
@@davidbaxter4910dude this is sick because if we find something that is human life or something then what if they are way smarter and they develop to be better and come to our planet
So are farts
"James Webb Telescope Discovers Signs of Life on K2-18b, 120 Lightyears Away... but there's a problem"--It's 120 light years away.
Dw we are planning to create powerful telescope in few years . We will be able to see the surface directly
Aside from the distance, the universe is expanding, so 124 LY now becomes more later! But we can't travel at the speed of light so its 1000's of years!! Everything is unreachable though.
I tried Uber, they don’t go there either. So…
@@relevantinformation6655 🤣🤣How about Lyft? 🤣🤣
2.2 million years with current tech
We need to travel fast imagine have a spaceship travelling 1Light speed per Min
The Cosmos is so glorious and mysterious that we should and need to evolve as our thoughts and will helps us to come together as a specie's among all species it's up to us . Destructive or development.
Meanwhile, on K2-18b, one life-form perks up, looks around, and tells his buddy, "Hey. I think someone is watching us."
SUBscribed !!!
Looks like that planet is going to need some Managed Democracy.
Why use the term infested?
What if we actually are the alien....?
We would be to another planets species if we went to their world we would ge the aliens and they would be aliens too us alien means foreigner weather that be earthen or extraterrestrial
😂😂😂😂😂 Wake up.... We came from some other species.. Don't matter if we call ourselves humanoids.. We don't know 50% of our own anathomy... Really hard to conclude right!
You are on to something...not NASA!😊
What if we are the aliens project .. what if they planted us here and did the same thing we’re doing now .. just hundreds of thousands of years ago 😂
@@qbanz00 considering we know large amounts about our own human evolution, it kinda negates that concept entirely, lol. Unless you think aliens came and dropped micro organisms here, and hoping that in three billion years they somehow turned into an (unknowable) "us".
😋
You do know it's a water world...
If we ever get proof of life out there, we will have to travel there.
It's like a self full filling prophecy.
The way the Star Trek communicator forced the creation of the flip phone.
Dick Tracy and the apple watch.
with the number of planets out there and the age of the universe surely there is a civilization that has advanced a measly ten thousand years beyond our available technologies; the chance is greater that we should have had obvious contact by them than not. The fact is, we are alone in the universe.
Re: WASP-76b does it mean over time the sun facing side of the planet get depleted of iron as it rains and solidifies on the dark side? If so would there be mountains of pure iron there?
Yes😅
Whether there is life or not is still to be determined.
Can we stop the war mongering the hate towards other countries and unite and evolve as one plant one life which is what we really are.😮
It’s a water world with life. I was there last year with my cousin (he forgot his flippers). It has breathtaking reefs filled with nothing but clownfish. Billions of them and not one named Nemo. Very strange place
Aliens are smarter than us they've already discovered life we're one step behind them lol
Only 124 lightyears :D
With our current space technology, it would take approximately 2.25 billion years to travel 124 light years if we would be able to maintain constant speed without deceleration phases.
And it is reason cuz people should stop wars and work toghether to discover new planets. I know im naive but its we need to save our population
Second model seems to fit better in the case of K2-18 b, at least under the logical thinking of gaseous planets to be the most common reality in what we know so far. When we invert the way we search, more promissing results will come. What I mean is this: Stop searching red dwarfs, it is totally pointless as space weather around them is full of UV and x-rays, their planets don't have magnetic fields because there is no dynamo effect, and as a result they are not protected even with the thickest atmospheres. K and G stars ONLY can give promises, and planets with radii smaller than 2 Earth radii.
Well if they want to discover life they shouldn’t expect it to exist the way it exists on earth. It could exist just fine on a planet just as you described but in a way where we don’t understand
@@qbanz00 It's all about theory, at the time being. We need TONS of data, and as an amateur astronomer I would like to see them. And about the last phrase of your reply, science is science when you understand and questions get less and less. Otherwise it is not science., so I convert "could" to "should" and I remove "don't".
Anyone saw devils rejects ? So the scene where dude says go looking for the dark one and he will appeaer well maybe its time us earth beings stopped trying to find life out there , we may all meet a horrible ending if we find a superior life form
120 light years away.Current technology craft would take 1363 years to travel one light year! So if calcs are correct(thank you-Quora)its observation only-probably indefinitely.
Plot twist, there is life except due to non extinction it’s the dinosaurs from the show dinosaurs.
THE only and greatest gain would be that we're not alone.
Mars will be our second home before this millennun is over 😊
Baby ducky hug you :)
OH , THERE'S LIFE ON MILLIONS OF PLANETS ❤
Terminids?
I bet THEY have universal Healthcare
It's like a snail 🐌 going around earth😂😂
I always ask, what will the discovery of life elsewhere do to the religious beliefs on earth?
No. K2-18 b is a super Earth exoplanet that orbits an M-type star. Its mass is 8.92 Earths, it takes 32.9 days to complete one orbit of its star, and is 0.1429 AU. Its star is highly unstable. K2-18 b is too close to the star. At mass 8.92 x Earths this is more like a Hot Jupiter. Neptune is four times the diameter of Earth and 17 times the mass. So no.
There’s life and we’re never gonna meet them
Why would different solar systems function EXACTLY like ours? A different periodic table due to sub-atomic rules unknown here on earth...
Planet K21 is where the terminator is from!👽
Yeah but when we look that far away we are essentially looking back in time
I'd argue that we're not primarily or essentially or basically looking back in time but that we are Literally looking back in time.😂🤷
Forget about a huge discovery of life on other planets, let's do what's easiest lol. The search for life on other planets based on life on Earth, but I believe anything is possible in our mind boggling huge and bizarre universe.
If it has intelligent life i dont think it would let us get close enough to discover that life!
How many years of more research, assuming all the evidence presents itself, are we from irrefutable evidence of life on another planet? Is JWST capable of providing that evidence in the next few years, or do we have to resort to other means of collecting it?
Irrefutable evidence can only be obtained by visiting a planet and finding life, and that requires our being _able_ to recognize life when we find it. JWST and other instruments can acquire suggestive but not irrefutable evidence. Even landers can be problematic. Look at the argument over the Viking Lander experiments. It's still an open question whether life was found or not. The pro and con arguments are both good, but not definitive.
We Need to initiate project " Stargate" 😂
I hope we undoubtedly discover life on another planet, it’s a nice thought that even when our planet is long gone, there’s other planets out there with intelligent life just doing its thing, as long as some place in existence has the potential for peace and happiness, I can die happy enough one day. We’re all just existing how we know to
Imagine going there in 124 ly with the help of several generations and the last generation will die there after finding out the life actually doesn't exist.
if it vaporizes everything then why doesn't it vaporizer the whole planet and is gravity holding everything togeather???
Only 124 light years?
NOT 124 Earth years!
What ever it was...this was light years away...no one guarantees if this is still habbited.
THAT’S where I left my car keys…
124 years since the light left is not much time. We have had life here for eons.
No sense in guessing. This where science leads the way to find out more definitively if it could support life. The science team researching this will provide more data later.
I HOPE IM STILL ALIVE WHEN WE FIND LIFE ON ANOTHER PLANET
If they stare back at us they will look at year 1900
As "infested" as Earth?
imagine if we had a planet war 1 💀💀💀💀
Get planet travel insurance....with Geico
Do they have oil
Suddenly we are the aliens...
It's a water world
Its life jim but not as we know it.
😊
But it's a red dwarf,... Of course the planet could have already fallen into their sun....
Does anyone here realize what "124 LYs" means?
124 years travel at light speed... (what still remains muuuuch too long for any human purpose)
Wait a minute: Are we able to travel at light speed?
As would say that french buddy "ça nous fait une belle jambe!"
Wouldn't we be smarter to try and solve our current and eternal problems (with those huge amounts of money we spill on such useless hobbies), like hunger, wars, earth systematic destruction and politic madness (all those subjects closely generated by each other)?
Maybe then would something like a "stars key" appear in front of us...
at 0.45%, and falling, of US national budget, I think they're doing great work with a relatively low budget than years past. I think it's an incredible undertaking, and I even fall into the "food insecurity sector myself" GO NASA, ESA, JAXA and India, China, and others... Even those durn Russians, We need to know this stuff! Edit: I do appreciate your concern nonetheless. 😏😏✌✌
To far away even if something is there so what what about our solar system
Well I think it’s krypton , that being said , here’s why
It’s 9 times bigger than earth
It spins much faster and is many times closer to its sun a red dwarf
1 year is 36 days
Gravity is probably unbearable for a human
Public ignorance (self included) is profound.
Didn’t someone find dms in some comets?
No, it didn't find anything. Can't find signs of life in our own solar system.
“Potential for life” and “signs of life” are NOT the same thing. Slow your roll, folks.
Solarians lives there
Who knows
I wonder what all the religious people will say after this discovery is confirmed 👍
this is a joke you guys. we dont even understand our own little neighborhood - we are constantly "shocked" or "surprised" everytime we learn about planets in our own solar system.
We literally just had the United States government confirmed that aliens not only exist but they have recovered crashed vehicles with aliens in them and these guys are still asking rather or not there is life on other planets🤦🏽.
if you believe that i got a bridge to sell you
I remember when science/news/etc was was not could be. SIGH.
This will be a letdown as usual.
With tech we could be there in 8 too 12 year possibly faster with the right motivation . Lol the word ...
Due to their distance, and the speed of light; any life we witness on any distance plant could be gone. The images we see, are from many years ago. The atmosphere of these planets can change.
if there is an abundance of methane. That might mean. There is a whole lot of farting going on. If you smell what I'm cooking!
so God never made anything that can live in fire 🔥hmmm
So what if there’s life on other planet? We go there and destroy it just what we are doing here on earth?
