![Everything NASA Discovered from James Webb's First Year in Space [4K]](/img/n.gif)
It would have been nice to have named the Cambridge Professor that first discovered this information. It was his discoveries that made you turn the Webb telescope onto this planet.
Indeed!
Nikku Madhusudhan
100% this
for sure! Webb and Nasa didnt 'Spot Life-Indicating Gas on Exoplanet', he did
Nikku is a cool name for a planet... "Welcome to Nikku", yes I can imagine that. Nikkunians living there as well. 😁
Nikku Madhusudhan discovered the signs which he was humble and hesitant to make the call which represents a sincere person in his field.
I hope other in peer group confirm and give him credit for this discovery 🤩
Astronomers first studied K2-18 b’s atmosphere with NASA’s Hubble Space Telescope in 2019.
Perhaps he was "humble and hesitant" because he knew that all he did was a relatively simple spectrum analysis of some light, and he got real lucky that the light he analyzed happened to show the "fingerprint" of those gases. Maybe he realizes his peers wouldn't think it was much more than getting very lucky. And maybe he realizes that the light he analyzed is over 100 years old (based on the time it took to travel here), and his results may no longer apply. And maybe he realized that the fact that it would take us over 1 million years to travel there makes this whole issue somewhat irrelevant, though fun to think about.
@@EETechStuff if we found a civilization even if 100000 Lightyears away from us it is not irrelevant, even if you only think of microorganisms if we found life 124 Lightyears away that means the Fermi paradox gets even weirder, because that proves that the universe is probably teeming with life nearly everywhere and we start worrying that the "big filter" for advanced civilizations are ahead of us
@@Aureonw And since our only connection to that planet is the light being reflected off its surface, how do you propose that we determine whether life ACTUALLY exists there?
@@EETechStuff biomarkers on the planet, ie certain chemicals etc world's conditions changing without certain explanation other than microorganisms slowly terraforming the world like in our world where Earth turned into a snowball many times due to too much oxygen from photosynthesis
Prof Nikku Madhusudhan of Cambridge Uni first spotted this THEN JWST pointed at this planet. Just seen an interview with him on LBC Radio..😊
I'm coming to this video after having watched that one.
You have to give credit to the astronomers that first studied K2-18 b’s atmosphere with NASA’s Hubble Space Telescope in 2019 as well.

Me too. Seeking truth. Good science 👍
fact we are able to detect something like DMS at a distance that would require 1million years to travel there is amazing
Prof Nikku Madhusudhan - Thank you
Prof Nikku Madhusudhan of Cambridge
It´s not a question of "if", it´s a question of "when"!
Wow, that was original!
Technically it wouldn't be click bait. He did explain it in full. This is one of the first that I have seen where he actually explained something to the title. And we all know we aren't alone in the universe. Wish they would allow the truth to be told. Humanity is ready for it.
"And we all know we aren't alone in the universe" How do we know this? One would certainly think that in the vast cosmos there should be other life but we don't know it as a fact at this point. To claim that we do is not scientific. And what is this "truth" that is being hidden from us?
We all do not know
Tell that to the religious.
Yes this Indian fellow found it .. I was watching him earlier
@@ACU_misfit It's funny how many people attack "the religious" as if they themselves have any idea what's going on. We could be in a simulation. Time may not actually be a real thing. If interdimensional beings exist, they're likely what spawned the mainstream religions. Thus, there is a lot of truth to religion. But it's not like you know something no one else does. Our greatest minds and yet to even crack the surface of understanding what life and conscious is. Only life creates life as far as we've observed, and we have no physics yet to explain it. Don't be an idiot. Einstein was smarter than you and he was a Christian.
This is indeed a tantalizing discovery !
To me as a chemist, the presence of measurable quantities of DMS in the atmosphere of K218-B is proof of the absence of oxygen. But hey, this is how it started here on Earth as well.
Why would there be lack of oxygen and lots of co2?
@@astronemir Ever ran a car in a closed garage? Not exactly the same compound but you get the picture.
For billions of years on Earth
Well considering there is mesurable levels of DMS in the earth's atmosphere, I'd be curious to know why that is.
@@renecapistran484 Because detection limits across methods. And light years.
Possibly name the professor who discovered this and not aclaim it to 'the james webb telescope'
Very informative but please credit the professor for his hard and diligent work on this major discorvery
Indeed the credits should go to nikku madhusudhan for his discovery
Feeling loved
Great channel
Planet Nikku 💯
Do we know of other sources of DMS though?
the magnetic field on that planet will surely knock me out.
this is really an exciting time of discovery.
Probably the gravity too, but That's space exploration for you, HOSTILE To we Humans!
@@wooddogg8the planet is 8,6 times the mass of earth
Thank god for that
Great news!!! A long term project to be undertaken and answer the great question,... but the real question is: will we be able to overcome our infinite thirst for self-destruction as a species?
Er, no. No we won't.
Where are you getting this 8 Light year number? K2-18B is 124 Light years away.
Why is your ''image'' of K218b just earth but mirrored?
We're going to need a better name than K2-18B.....
Why . I think it s cute
Vulcan 😁
Klaatu, maybe?
It was the only alien name or place I could think of that had significant letters and sounds that correspond with the astronomer's name.
But yes, K2-18b is too clumsy.
Keplers 2 is K2 aka what system it was found with/ useing the kepler telescope, 18B is I believe the direction and star it orbits.
Planet Tony.🎉
Its interestyng I like it
Great ! Maybe we have a chance to find out we arent alone before we go extinct !
Extinct from what?
@@AORD72Yo Momma

@@AORD72 Pole shift happening now.. We're toast!
@@Ogt92 You think the poles moving is going to kill everybody? why would you think that.
Hooray for K218B
JAMES WEBB YAY!
Woah 😮
You really need to name the professor who made the discovery, it's unfair on him when he is rightly so beaming from ear to ear about the discovery he has made, it absolutely is not the jwst
Does spectroscopy data also have the same time lag as light? Are the readings of the present or of light years away..
Is there anything that can travel faster than light?
That's actually a really good point
We use the light that passes through the planets atmosphere as it transits its host star to do the spectroscopy so that light is 124 years old.
Do we have data on it's magnetosphere?
This news is exciting and also saddening as there is no chance of real time contact.
When will we know more? Wow
No chance of a pub then.
in a few billion years maybe don't lose hope
Maybe give the Cambridge professor a shout out, he discovered it
Of course we are not alone
I just saw an interview on YT of the man who discovered this planet. It was an Indian man from Cambridge University.
It was not Webb or NASA. Is there a way you can edit this video to give the man his respects?
is it tidally locked?
For the forseeable future it will only ever be a signature. We want the signator.
Of course the dynamic of the Drake Equation, while making it unlikely that there is intelligent life there, sets up the possiblilty of this planet being at least somewhere on the evolution spectrum..
Astronomy has come a long way since the 1990's. I remember prior to Hubble they didn't even know if other planets existed in the universe.
Humanity has been through much worse and yet it survives. I think humanity will find the strength to succeed.
Same applies on earth..military experience..flash bang..you will see the flash..the bang depends on how far away..so imagine that in a cosmic compilation...i think a teacher said if an alien race was able to see us at their time..they wouldn't see us currently..but preastoric...
Great point! If the Life form has that Understanding of another Existence even though their own Higher authority Scientifically sees Earth through the Telescope as Cavemen or Prehistoric would they then decide to Investigate further and find Earth beings have Advanced beyond that realm just out of Alien Curiosity then either help us Advance Scientifically or avoid us Totally because Humanity is too Barbaric as We invade or Bomb one another.
I feel that We are not Alone in the Universe or here on Earth. It's only a matter of time before something is discovered accidentally through technology and a clear clip or picture becomes final proof or Alien Life emerges from the Frozen Antarctic or from Miles Deep Underwater as in Atlantis.
Don't think that DMS has been definitively been identified on KT-18b yet. Hints that it is "likely" present but apparntly more scientific analysis ongoing to actually "confirm" presence of DMS.
yes i was hoping for some sort of confidence level in the presence of DMS but he started waffling about the topic in general
WOW
I think there can never be certainty about life on any exoplanet. We will only ever be able to say "It may support life" and that's the truth of it.
There can be certainty : a radio signal like in Contact (for intelligent life that is).
I'm pessimistic about the future. Given the current trend of banning books, we're not far from what's portrayed in Interstellar, where they questioned the moon landings, etc. Confirmation of alien life might go against someone's doctrine. Who knows what happens next. That's not a future I would want.
Then don't accept it. The people who burn books don't respect the humanity of their so called enemies, but we've always beaten them in the past
@@edwardpoe7323 I'm not sure. We are only aware of what we haven't lost. Remember the library at Alexandria?
The only books being banned are books with inappropriate subject matter for the age and grade of the kids, none of these book are banned at book stores, public libraries, and places like Amazon. The books are readily available for free from the public library and you can buy them, they are just cited as inappropriate for young children.
@@michaeldavidfigures9842 look what we have now, there have been a few times in history that civilizations have collapsed maybe it won't happen this time
the trend of banning books is mostly in the US and the UK and the world doesn't revolve around the USA like in hollywood movies so calm down and stop watching movies
we are not even close to the book 1984 either. more than half the people who say that, have not read the book.
Right On Ape Man
Just show us the aliens already!! 😎
And the antigravity engines 😜
They have to keep it a secret and unavailable for us or the humans would fly around and cause chaos in the galaxy.
My life.
Better telescopes and who knows what else is coming. Patience 😞
@@Henrik.Yngvesson nailed it
Why don't they look at star systems that people claim to have met people from? It would answer questions either way. Look at these systems like Zeta Reticuli or Arcturus in the Boötes constellation.
It's 729 Trillion miles away
Change the NASA narrative, you need to give the Prof the real credit here, Webb wouldnt be pointed at the planet without the research of the Prof
Long time to get there huh?
This video is really cool, but where is this planet? Where is the news release. Need proof.
I see comments stating "oh why bother we'll never get there anyway it's 24 light years away. If a Corporation even gets the slightest whiff of possible profits with regulation being so far away, you see how fast they develope the means to get there.
124 light years away*
@GeoPePeTto it's only one hundred light years off. What's the big deal, we'll never break the light barrier in our lifetimes
Thank you Professor Madhusudhan. You have opened a door and allowed more light on a very old question. All honor to you Professor Madhusudhan.
@@JanBoomgaarden-xl8xs The more interesting part of this is how much long ago the planet had this gas composition. It’s 124 years ago. True, in the grand scheme of the universe, it’s nothing. You’re right. But I just wanted to correct you for other people to know. I’m positive you knew the distance and it was just a typo.
Does it have a moon ? Not to say you are wrong but there is more needed to successfully support life.
we need 1000 steps closer for me to consider this desperation to find aliens, good luck
Just prepare yourself the universe is not a sterile place
There are some 60,000 solar systems just within 100ly of us. That's close enough for life to spread between systems even if it began in ours. There's no chance that there isn't life elsewhere, especially when you consider how unlikely it is also that it magically spawned on earth.
@@jamescarter8311 it would take more than just few elements to have life, human existence is not that simple because of few elements,
@@edwardpoe7323 we will never know because we can never get there, a few images here and there not gonna do any good, human existence will extinct sooner than we all hope
@@minhnguyen-mk9om people have been talking about the end of the world since the world began. Yet the story continues.
Fascinating. Somebody tried to hide from us but farted too much.
Protecting these worlds ? 😂 from what ? ...Can't wait to hear this explanation 😅😅😅
our 'sin' of existing
Protecting the microorganisms from extinction by us I guess
Is that planet a unique living organism?
it sounds good, but with all due respect, when it comes from NASA it makes it a little hard to believe, we've been lying to so many times that when I hear from news from NASAS SCIENTISTS and they tell me to look south to the sky, I'll look north and find out new things and hard to explain.
But it is a very interesting video.
It wasnt discovered by Nasa. A scientist from Cambridge University made the discovery and they quietly ignored that bit
So, there are, greenhose- gases in atmosphere. They are also in Venus. Is that habitablle.
don't people who say the sphinx is much older than credited say that the proof is that it faces east, looking at the leo constellation approximately 10 000 yrs ago. just maybe...
no one credible claims the sphynx is older it's been debunked many times and been debunked by people who believe the sphynx was older so to me that's not even worth talking about those people anymore.
@@user-lz2es2bk6x Yeah no. Nobody has proven that they aren't older. They used carbon dating on organic material that could have absolutely gotten there by way of repairs. All they have are the best guesses they can come up with.
@@footballlife1543 Those who claim it's older are the ones who need to prove it, not the other way.
@cinegabweb You can look at it how you want to but the point still remains they are relying on a source that might not be good in the first place.
@@user-lz2es2bk6x the erosion looked liked it was caused by water when i visited it. when did rain enough in the desert to cause that especially as it was covered in sand ?. i'm open minded enough to accept science gets things wrong sometimes so facts can change to reflect that.
Seems to be many potential life planets located around red dwarfs 🤔
Don't think we will get there anytime soon.
a 1-sigma detection can be an error in the data.
yes they made it public without double checking the date, they always do stupid things like that at NASA. that's why no one trust nasa they always say things without knowing if it's an error or not
Wow, we may have discovered goo on a planet 124 light years away.
would be quite significant. i dont think we even know the chance of going from random chemicals to cells of life, and then cells to multi-cellular organisms. if there's a 'nearby' planet on life it's signficiant
@@TicTac2 "Significant" greatly diminishes over distance and time. If it was only 1 light year from earth, using current technology, it would take approximately 2,958 years to get there. That planet is literally 366,792 years from home. At that distance, its much closer to barely relevant. Sure technology will improve over time but seriously, anything that far out is nothing but a complete waste of time, energy, effort and money. Concentrate on things that might help future generations (maybe over the next 2 to 500 hundred years) not a "Maybe there is goo" on a planet that is 4,585 lifetimes away from earth. (At an average of 80yrs per lifetime)
120 light years makes it basically unreachable. Forever. Interstellar travel is impossible.
Planet Nikku
And so the 3-Body Problem begins...
I can only assume that if there is life on that planet, the glory days are gone. The star is old.
Okay, so if there is actually life on this planet there is probably life on lots of other planets that we have yet to find, but one thing is certain life on our planet and if it’s seen from another planet it’s most likely they are in the same predicament as us, unable to travel faster than light, and every thing we or they looked at has already happened, so using space time looking out millions of years ago we will never meet any life forms from that time period, maybe from this planet we will in a few million years if we survive that long. We are a grain of sand in the hour glass the size of universe.
Fermi paradox gets a wrench thrown on it, if life is so common why no advanced civilizations can be seen?, then it becomes proof that the big filter for advanced species is actually ahead of us
Follow the money. At 6:40 he says "the discovery would likely lead to a significant increase in funding and resources for space research...", which is what they really care about. Forget the fact that the light-based data this is based on is hundreds of years old (the time it took for the light to travel to us for analysis) and therefore may no longer apply, but more importantly it's impossible for us to even consider travelling such a distance, since it would take millions of years to get there. But what's really important for NASA is they hype this as much as possible so it will help them get the increase in funding, which they blatantly admit in this video. And to make the jump from "presence of gases" to "presence of intelligent life" is ludicrous. Fun to think about, but ultimately irrelevant.
Brother, it's 127 light years away, if it existed 127 years ago it exists now as well. Life doesn't just go extinct in a century, and just knowing life is possible on other planets would be huge.
@@snakev7140 Do a little research on what's been done over the last 100 years in trying to determine whether life exists on Mars, even after we've had probes land there (and in fact one is there now). You'll quickly realize that it's extremely complicated, even if we have probes there. We still aren't certain about Mars. So proving life exists 127 light years away when it's impossible to send probes is physically impossible. All they can do is tell us "yeah, conditions might exist" but can never prove it, just like conditions might exist on Mars. And to say "life doesn't go extinct in a century" is just ludicrous. Do some research.
I can feel you stench from 124 light years away should be the first message we send

#super earth 🌎
Leave the place alone. Let the natural cycles determine its outcome.
red sun higher pressure and gravity than earth...just rename it Krypton already
Either there is some novel chemical process heretofore unknown to us or there's life.
I hope that life out there. Has a better intelligence than we do. Otherwise they will have the same outcome we are experiencing. Which is an end to our civilization. 😢
There's good intelligence and evil intelligence, our world clearly has and is still being guided by evil.
A magnetic feild would up the odds large!
How far away. 124 light years.we could never get there with our technology. 1 light year ,and we struggle.
just walk?
nah why not just jump there? like jump really really high
@@Austin_Playz27Can you?
@@Aureonw hmmm your right maybe i would need a chair to get a little higher of a jump
Hate to say it again ! I told you so ! Life is everywhere !
Imagine all the money and resources put into war be used for science to better our lives and space exploration.
Self and surrounding speech. First and experiment our future intantat that
The answer is never aliens, until it is.
If alien life exists on that planet, nothing worse could happen to it than us finding out. We don’t even respect our own.
My next door neighbor is an alien.
Mork from Ork
Lies!!!!!!!
When we look this planet , its 120 years ago ?
Yes. That’s the time it took for the light (radiation) to travel to us.
It'll take about 1.6 million years to travel 100 light years. So hurry start packing you mite miss the plane ...🤣🤣🤣🤣
Actually, if you do the math on our current ability/tech it would take about 213 million years to get there. Our fastest human made probe has traveled about 395,000 miles per hour and assuming that a lightyear is close to 6 trillion miles. Then you have the little fact that this planet is 125 light years away…. Plus I’m not even considering if this planet is moving away from us. We need teleportation 😉
did chatGPT wrote the last part of this video
It's not terrestrial life, it should be celestial life:)
I JUST WANT TO SAY ONE WORD TO WHO EVER IS COMING, OR WHO S ALREADY HERE.......
WELCOME.😇😇❤❤🙏🙏
While I think the possible discovery of life on another planet is a life-changing achievement, you lost me talking about preparing to bridge the communication gap with aliens.🤔
Let us find peace in our own planet there is s hopeout there. We should not let this chance to go.
Finally 🙄
Still way too far. Impossible to reach
It's a mathematical certainty there is other life out there!
Actually it is not mathematically certain at all. Math may reveal a probability but there is no math that proves that there must be other life out there.
Drake's equation?
Utter horseshit. The odds are definitely in favor of there being other life, but it is FFFAAAARRRRRR from a "mathematical certainty". Such a claim reeks of tinfoil.
Rubbish. For there to be a mathematical certainty you have to know how life started to provide a probability. How did life start? Nobody knows, so you can't calculate any odds. It took ~3 billion years to go from single cell life to multi cell life on earth, and the universe is thought to be about 13 billion years old. It is possible that earth is the only place of life, really we have not enough knowledge yet to make a strong prediction.
@@slatvatfatcat it's not that bad. barely possible for there to not be a single cell of life in the universe and yet the one planet that does has life has something as advanced as humans
If there is life out there, they are probably wondering the same thing 🤔
That's all great, but using a telescope to get all this information are we not looking back in time? the planet as we speak might be in an ice age if we were there today? or not even still exist.
Its only 124 light years away so we are only looking 124 years in the past.
just zoom in the planet...
We got a planet with water and potential life before gta 6
Energy companies rubbing their hands.....if only we could exploit 🤔
