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.

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.

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.

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.
Why the aliens won't come here, they are watching us from home.

Professor Nikku Madhusudhan is the person that discovered the possiblity of life on K2-18b. He is British and works at Cambrigde university England.
The scientist who discovered this is Prof. Nikku Madhusudhan. (Spelled Ma-du-su-dan) from Cambridge University.
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.

Is interesting how the feeling of lonliness we share moves the desire to finding someone else.

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?
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.

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?
@theeddorian
11 күн бұрын
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.
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.
“Potential for life” and “signs of life” are NOT the same thing. Slow your roll, folks.

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...

There’s life and we’re never gonna meet them
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.
Didn’t someone find dms in some comets?
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
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 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
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.
But it's a red dwarf,... Of course the planet could have already fallen into their sun....
I HOPE IM STILL ALIVE WHEN WE FIND LIFE ON ANOTHER PLANET
Its life jim but not as we know it.
All of this universe just to work and pay bills. 😂😂😂😂😂😂😂
I bet THEY have universal Healthcare
I wonder what all the religious people will say after this discovery is confirmed 👍
