Scientist Who Found First Signs of Life on K2-18b Using JWST Says There's "More DMS Than Earth" 

What makes JWST so valuable is the ability to analyse atmospherics on other worlds, the chemistry of life. Seeing things millions of light years away is needed, and exciting for sure, but finding signs of life is the real goal.

I notice the cost of JWST isn’t discussed anymore as it makes one astounding discovery after another

Came back last week from a three week cruise there. Very nice planet, interesting sites.

More habitable than Earth? Not for humans. It has a radius 2.5 times that of our world, meaning that total mass is at least 10 times that of our world. You would survive about 4 minutes before your heart gave out or you suffocate because the muscles are far too weak to breath, or the amount of blood pressure required to move such heavy blood through your body would either blow your heart out in minutes or blow the walls of your arteries and veins out, capillaries first. The volume of a planet 2.5 times the radius of ours would be 4,188,790,204,786.4 cubic miles, compare that to Earth at 260 billion cubic miles. That is 16 times as much planet as ours. And all of it is exerting gravitational pull on the surface. It is possible that those miles of stuff are made up of lighter elements and lots of water, but the gravity would be at least 10 times that of Earth. I weigh 165 pounds on our world, and my heart does fine. But if I weighed 1,650 my heart could not pump the blood to my head or up my legs because it also would weigh ten times as much. Even if your heart could squeeze hard enough to move the liquid in your arteries the sheer force of that much squeezing would blow out the artery walls.

Things are getting interesting! 😀

DMS actually can be produced by abiotic processes, like interactions between water and sulfide minerals in ultraviolet light, or some volcanic activity.

If K2-18 star was not a red dwarf, I would certainly believe they found something. I wouldn't like to be pessimistic but I can't be sure about life there, for the profound reasons: huge amounts of X-rays, close planetary orbit, tidally locked planet (no spin/no dynamo effect/no magnetic field) to its star. More no's than yes's, derived by logic, physics and planetary parameters for K2-18 b, rather than pessimism.

It’s obvious there is life in the universe besides us. It is more likely than not.

If it is more habitable than Earth, wouldn't one think it is already occupied by indigenous lifeforms? We need to observe and study it secretly...non interference...even if that life is only microbial

I'm utterly astonished by the narrow perspective held by scientists, limiting the building blocks of life in the vast expanse of the universe to carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. This viewpoint highlights the limitations of our current understanding of the vast and mysterious cosmos.

So many armchair scientists in this comment thread 😂

Absolutely fascinating love this ❤

The planet is a "mini-neptune", not a super-Earth, SORRY! 2.6 times the radius of Earth, discovered 2015 by the Kepler space telescope, during its K2 mission

It is 120+light years away! What's the point even if it is 100x better than earth? We(human, not machine) will need a few thousand years to reach the edge of our solar system. And maybe we can't even reach Alpha Centauri for 100, 000 years

Just Googled that 1 light year is very far and currently it will take thousands of years to get there, I was hoping we could just send a probe there in the next year to see what's cooking.

How is it that they know so much about atmospheric chemical signatures, but only have crude models to describe or ascertain surface temperature? Seems like there should be a concentrated effort to improve this significant research deficiency, before spending so much time and resources based on wild estimates.

We're getting aliens before gta6

Man, that's awesome! Thank to Nikku and the Team! NASA too!

Wait, does the fact that there's liquid water droplets on Wasp -76b mean the possibility of aerial microscopic life?

Now, we need to work on finding a way to get there at warp speed or super warp speed

Even if there is life they make em pay taxes…call it the galaxy tax😂😂😂

We finally know we are not alone in the the universe if this is confirmed. What if earth was a water world in the distant past?

More evidence has shown that life is unlikely on this planet. It's more likely of a Neptune planet

Fortunately for kt- 18b it's permanently unreachable by humans.

We’re looking at something far far away and in the past. How do we know that it currently has the ability to possibly have life?

Well this aged fast...

But that planet doesn't have my mother My Dog my daughter.. I'm not going there period.. Please don't fuk up my planet Earth Period.. I love science

There are 9 earth-like planets in addition to earth.

Can we wait until a team of other scientists observe and agree before saying life elsewhere? I mean, every single exoplanet in the universe is 50/50 for life. That says absolutely nothing at all. Everyone calm down until this is severely scrutinized.

It's a 1-sigma DMS detection signal. Pretty flimsy evidence. Wake me when it's 3-sigma.

At 120 light years, that gives a volume of over 60K cubic light years. At our neighborhood's stellar density, that's about 250 stars within 120 lyrs. That about a .4% chance of a star having life as we know it. Now we have a better number for the Drake Equation, anyhow. So, with 100 billion stars, even if it's a one in a million chance to evolve intelligent life like us, there should be at least forty or so other intelligences in our Milkyway Galaxy, at some stage of evolution.

This is amazing! Can't wait to know more about it!

"Detecting multiple unidentified life forms in the region"

Wasps Glory is maybe a small hill sphere of EM mass which would be eventually turbulent hence its non constantly observable. The K2 1B chemistry is encouraging and maybe some comparative transitional Planum Temporale based on 4 dimentional spacetime. Organisms here are some thesis. The calculous of stars to planetary temperature should be in the spectrometry , the lights constant and possible relative angle of transit , L Point and the 3.5K C.The radius is in the dimming and its probably not oblong lol

That planet is 8x more massive than earth , yeah f that i aint living there regardless of aliens there 💀💀💀

Life can be a plant, it doesnt necessarily have to be people. Thats what I remembered from Astronomy..

They realy need to be sending alot of satalites there. Atless leave the plant signs they are not alone

My guess is they have either missed a simpler, more obvious possibility for a 'best fit' model, or included a fairly irrational assumption somewhere in the logic of their hypothesis construction. It blows my mind how many times claims or inferences like this at some point have a blindingly obvious flaw uncovered in a follow-up investigation, study or review. Too often I've thought: "How the hell is that not one of the first things you check/think of". And if a simpleton like me can spot or think of some of these things they miss, then I think these people need a holiday, or Jesus, or meth or something.

Fermi paradox life is abundant in the universe intelligent life is super extremely rare

exxciting find. wow. finally.

WASP-76b, you keep the hell away from K2-18b!......(I know I know. It will.)

To envoke occam's razor... Its more likely to be a gas giant 😑 Fingers crossed tho for an ocean world with a microbial biosphere 🤞🤞

It took Earth 3.7 - 4 billion years to get where we are from primordial soup.

Whst is our definition of life 🤔

Life here confirms that life does exist. For some reason, it's illogical to think that, in infinity, that's it.

Merely theories and hypothesis! Unless proven. Don’t forget how science experiments starts: by hypothesis. 😊

If it is life then that would be quite amazing but even if the academics involved think it 50:50 it is still statistically unlikely, it could just be that there are geological and chemical processes on other planets that we simply do not understand yet. The planet is half the age of The Earth and receives about 90% of the energy so it is possible that microbial life could exist there, all things being equal. The absence of Oxygen in the atmosphere is consistent with early Earth but the absence of H20 surely suggests that this can not be a water World?

They are over reaching with the suppositions of what they think they found to get famous and get grants.

DMS: Proof that convergent evolution is universal.

But what does it eat?

Realy I like this video its so interestyng

It was me. The latest home for his newest mistress.

Turn down the music. I could barely understand what he was saying

Who comes up with these names??? Could we get something a little more creative & memorable?

Is the planet in the goldylox zone how big is it comp Aired to earth

When do we leave?

fastest probe would take over 1,000 years to arrive there

Life is more prevalent than science wants to admit. It's human arrogance

So its roughly 720 trillion miles away. This means its within the milky way. Now depending on the age of star system and the fact we are all moving in the same direction within our galaxy. There is a very high chance of life as it would be around the same age give or take a few billion years. Its mad saying a few billion years as a give or take 😂

A humanidade se limita ao seu próprio conhecimento. O entendimento expande o conhecimento.

It may as well mean that Mr. Dr. Nikku Madhusudhan is making some extremely noisy publicity for himself... Let's think about what is more likely: the possibility of life on the planet K2-18b or the doctor's self-advertisement? Especially when the evidence is so weak that it can only be considered as a probability of life, and a rather low one at that. NOT LIFE!!!!

Wow this wasp 76 planet is pretty cool.

How we gonna get there 🤔

Why are his students not getting the limelight ?

A gas giant is more likely!

More habitable than Earth? How stupid. No place in the Universe is more habitable for humans then Earth.

We are not even sure if planet 9 exists in our solar system and bro says he found Aliens 120 light years away😜😂😂😂

Unfortunately no oil was detected on this planet. All further observations will be suspended in order to save funding to finding planets with oil. End of story

JWST. an overpriced non existent pce of junk. Why would we have this telescope focusing on non living planets. Focus on exoplanets that can be habitable by humans. I just find it suspicious on who decides where this telescope focuses on. Start naming these exoplanets. These number letter sequence naming is like BMW . we need to focus on planets that have the bio signatures of life. I bet that K2B planet has life on it. Lets study it completely than looking 500 light years away at a hellish planet. We could never get there so why are we looking. It is just suspicous to me. Like Mars, aka red desert in Australia lol

Can't we just point JWST to the planet and focus for a detailed image?

So this is just a repeat video of the other one I watched, but what I am not finding is a video explaining how they were wrong. That will ensure I won't subscribe.

It would take years 😭 traveling in space to travel planet to planet

So nothing is confirmed. Meaning no life detected smh im tired of this kind of videos particularly.

Also we're in a matrix-simulation. So aliens have been out there for while. They're somewhere watching episodes of alien Frasier and drinking alien coffee.

Fly JWST into the humam womb, see if we spot signs of human life there.

Ok so how do we get there?

It’s more than 50/50

Going there will take your life span and still not there😂😂😂

What's at the bottom of the ocean, the very depths of the bottom? Nobody really knows. But from a picture deep deep in space, somebody has found signs of life.....

Sounds like @ bluebook has too much time on their hands.

And what if said alien life isnt friendly? Congrats u just killed mankind cause u asked can we instead of should we

So we're is the aliens

There is life everywhere. Life is on every planet. On every moon space rock and on every Sun!

if life is there & its not wit war n nuclear weapons i wanna live there,seriously😮

For decades we have heard this nonsense.

I don't care.

It’s the one piece

🤔💬I’m at a red carpet instructor we have politics DONT FORGET EURO ego!!!!! And a Jim Carrey Good Sir!! And his greed? EVIDENTLY ALL FOR NOT IN HIS MIND STRICT STRICT STRICT !!!!

Soon to be renamed Pandora

No life any planet grass and. Trees found

Is there life on other worlds? I have complete confidence there is. Does it matter? Not in the slightest. I cannot wrap my head around why it's so "amazing" to people to consider that we may actually have proof. So what if we do? How does your life change? Granted, it's interesting and leads one to imagine the forms that life takes and how similar to life on earth, but just simply knowing it is there will not affect my day to day in any way... outside of others freaking out about something that really doesn't matter.

Your knowledge of iron is flawed!

Isn't this the planet that is something like 137 light years from earth? Scientists can't figure out our own planet, they can't tell you what is happening at the bottom of our oceans and have a mediocre record as far as weather forecasts yet they have all of this information on a place that we probably won't be able to visit for several thousand years if were lucky. Interesting but a waste of time, energy and resources that could be utilized in solving so many problems and or answering questions at home.

i find this just possible speculation based from infos from JWST that hasn't gathered accurate data

All we gotta do is send a submarine drone to swim around and look for fish and then we set

3 body problem 😂

Subnautica anyone lol

Yeah right, sure.... 😑
