I appreciate that it's important to be a skeptic when it comes to something as groundbreaking as potentially detecting life in another planet but it's just not accurate to describe the original potential DMS detection as "extremely low and practically insignificant". The paper found the most likely model for detection to be 1 sigma, which is a 68 percent likelihood, and that's after accounting for the gap in the detector (without the gap it would have been a 3 sigma detection, or 99.7%). If you don't agree with the paper then fine, please let us know what you think the problems are. Also, regarding the new paper from NASA, it found the that a Hycean world with life and a mini Neptune were "equally likely" fits to the data, and neither an exact match, but that data plotted did not account for DMS. Also, it does not explain the lack of Ammonia, something you would expect to see from a mini Neptune.

Furthermore, the planet has hydrogen for its atmosphere, which masks DMS. Thus, the paper was pure speculation.

Great vid. It’s worth noting that the lead scientist on this potential discovery is also tentative at best, regarding whether this is an indication of life. In the interview I saw of him, while he was quite fascinated with the data, he was not trying to present the indications as anything close to definitive. His assessment was pretty on match with this content.

I'm sure this has been noted but last Friday, 10 days after this video, JSWT focused on K2-18b for 8 straight hours to directly answer what it's actual composition is, maybe Anton didn't look at the observation list but, we will know if it has DMS, also they did detect Oxygen in addition, which when you combine CO2, Oxygen, Nitrogen, Methane, AND DMS... sorry but anyone who denies it as not a biosignature, (once this data collected from 4/27/24) again IF all of these chemicals, molecules, and gasses are present, then just make the argument against then deny Earth has life as its almost a mirrored atmosphere to the planet those deniers are standing on and delusional, because they would simply in denial. Likely down to less than one percent chance it wouldnt be the first proof of exolife, and will be on the wrong side of history. If it comes back otherwise fine, just always saying it can somehow be produced without life then deny your alive because you might as well be brain dead at that point.

You are way too emotional about this. And jumping to too many conclusions. JWST already looked at K2-18b and found it has a likely dry atmosphere (no water vapor), which is a pretty strong anti-life signature in and of itself. Methane, CO2, Nitrogen, and Oxygen are common substances found on many worlds just in our own star system, and are not particularly significant as biomarkers themselves. The only important finding that brings up the possibility of life on K2-18b is the possible detection of DMS, and we don't know if it's naturally occurring or created by life. We assume it would signal life, as it doesn't appear to naturally occur on Earth, but that doesn't meant there aren't geologic or chemical processes which could naturally generate it outside of life form activity. Other than that, this is a likely small gas planet with a dry atmosphere of mostly hydrogen, orbiting a red dwarf star younger than Earth. It's not particularly suitable for life as we understand it, and may be tidally locked, which would make it even less suitable. It also appears that the lower atmosphere is extremely hot, and would be even more unsuitable for life to evolve.

@mandrewmx

Ай бұрын

@@berserkasaurusrex4233 You've effectively captured the essence of the debate: the detection of DMS may indicate life, but its presence alone isn't conclusive, as non-biological processes might also produce it. Indeed, the detected environment was not one of a dry atmosphere, but one that included water vapor (Idk where you heard it isn’t present but every things I can find that is stated that water vaper was present), oxygen, CO2, and methane, along with a 51% chance of DMS, significantly strengthens the argument for a potentially habitable world. However, your point also stands that the presence of biologically-associated molecules like DMS doesn't definitively prove life; these elements could arise naturally in certain conditions. Anton’s skepticism is clear in his insistence on more data, even though recent observations by the JWST team suggest that these compounds might significantly point toward biological activity. They did train it on the planet, as I stated, last Friday, again, for a further eight hours to make the readings statistically empirical, but we will not know the true composition and how the conditions you stated would affect the possibility for life for at least a few more months Moreover, the existence of a surface ocean, despite the planet orbiting a red dwarf and possibly being tidally locked, does not negate the possibility of life. The arguments about the planetary mass and environmental conditions only add complexity to our understanding rather than conclusively ruling out life. In essence, while observational data continue to mount, the debate remains open, and as Anton exemplifies, even overwhelming evidence might not suffice for some skeptics. Therefore, while exploration and analysis proceed, we must prepare for both ongoing debate and potential disappointment in our quest to definitively prove extraterrestrial life.

2.6 times Earth's radius, 8.6 times Earth's mass. Surface gravity of about 1.27G. However, it's density points to it being a Neptune-like planet, so it probably doesn't have a solid surface. Given that there doesn't appear to be any water in the atmosphere itself, and the DMS levels appear much higher than on Earth, a planet covered in algae-rich oceans, this would suggest that the observation is simply wrong and the DMS detection is a false positive, or that the planet has a geologic or chemical capacity to create DMS naturally that we haven't observed previously. Since we don't have any tidally locked mini-gas giants orbiting young red dwarf stars to directly observe, we can't really know what chemicals can be generated in such planetary environments. The DMS detection is itself only a possibility, and not confirmed as yet. It's difficult to spectroscopically analyze planets orbiting dim red dwarfs like K2-18.

So life can exist in extremes but not enough to become intelligent on a scale like us. On a side note, we may never know simply because of the Fermi Paradox rule that once civilizations come to a certain developmental stage, they tend to wipe themselves out.

Thanks for your continuing work, Anton. Very inspiring. Just a theory> ( source Wiki ) In industry, dimethyl sulfide is produced by treating hydrogen sulfide with excess methanol over an aluminium oxide catalyst. On a world like K2-18b, if it has a thick atmosphere that touches a rocky crust or mantle the heat from pressure could vaporise aluminium. That is then oxidized and exposed to lightning. Thus producing the catalyst. Methanol we know is abundant in nature as is hydrogen sulphide. All the proverbial elements are there to possibly produce the equivalent industrial-made DMS. Or have I missed a step? Inquiring minds would like to know. Obviously, it would be great to know for sure that there is extraterrestrial life but one does not like to lie to oneself.

JWST is doing a MIRI observation 1 week from now (April 25th/26th), so within a few months we'll have more papers about this. But regardless of that, even in an unlikely scenario that JWST manages to discover every possible biomarker here, it still won't count as discovery of life because we will never be able to rule out that some combination of natural processes that no one's ever thought about isn't responsible for this. The only way to actually discover extrasolar life will be to fly a spacecraft there, land, collect samples and send back an actual photograph of a microbe. Which will probably never happen.

And that's the problem with the way we search for life. Skepticism is undefeatable. If it's possible through life, it's almost always possible through something else, and our current mentality is to fall back on that no matter what. "it's never aliens... And it never will be aliens"

I'm so tired of these false finds. I wish we would just find concrete solid evidence of life already.

Look on the bright side: when it IS discovered, the discovery will be something more concrete than “We may have found hints that maybe microbes might possibly be in the atmosphere of this one planet.” (They might even use the word “definitely”.)

That is what I like about this channel! You really lay out the facts and let us know what the real answer is. While I find this topic fascinating, I really wish they would seriously look at some planets that are more like ours as that is one of the things James Webb can do!

We know far too little about life on our own planet and are constantly surprised by where we find it here and how it can find a way to exist in places we consider extreme. We also have a problem clearly defining what is alive or what life exactly is. We have a lot to learn here first.

I don't know where you get these out-dated ideas. We know quite a bit about life and there is an entire field devoted to the understanding of it - ORGANIC CHEMISTRY. Moreover, we have a pretty good definition of life as we know it and it works pretty well. HINT: Viruses are not alive. You really should keep up - there is more to science than astronomy .

@@kaoskronostyche9939 Your idea is actually quite outdated and narrow minded. There's more to discovering life and understanding it then simple chemistry, also it has been very recently debated if certain viruses are alive, due to their size and complexity. These virus's being discovered only in the last year or so. Furthermore it was only a few months ago that a Japanese science team found bacteria and life that was thousands of years old, miles beneath an ocean floor, a place they didn't expect to find anything. So there is actually much we still need to learn about life. Also keep in mind we've only really been studying the field and understanding it for a little over a century, which is next to nothing.

Are you suggesting if we found viruses from another world, it wouldn't be evidence of life? You don't think RNA would be evidence of life? It's not that we know little or life on Earth; it's that we know little about abiogenesis generally and how it could happen on other worlds

It's not the dark forest, there is no paradox we are all going to die. I think 99.9% of all species are extinct, in 100 years we may be too. It's not that civilization doesn't happen out there but it's rare, very short-lived and leads to extinction on a large timeline covering millions of years it could have happened multiple times on Earth and we wouldn't even know. It's an easy solution, there are no "evolved" beings just the weapons we create, the wars then we will go silent in the future just like the past it's dead out there

The fermi paradox predicates itself on the notion that intelligence and civilization is long-lived and able to cross vast distances unscathed.

Can you make a video about different forms of information we gather from other planets and how long it take for each type to reach us? Or are all observations done based on the light that has reached us? If not and they have slight delays, it would make an interesting topic to hear about. Because in my head it feels like we (for example) see one era visually, but statistically we have gathered details of even later eras, since light is the fastest to reach us. This is purely my assumption based on the belief that not all observations/studies are made using light

You are sounding great!

I remember a scientist saying something to the effect of “pond scum is probably abundant” in the universe. This video brought that back. FWIW.

Just a thought could it also be that we are not getting the full data from our observations? The distance and other objects and processes of the universe could limit or enhance what we receive back from the telescope, right?

Anton didn't explain what the apparent "hint" of DMS on KT18b is. DMS exists in tiny concentrations on Earth so perhaps such concentration is difficult to confirm on the distant KT18b.

You always build me up and then pop my bubble 😅

@antonpetrov question: what do you think of the professor’s statement that it can be ”50/50” chance that the Discovery means Life? (I think the prof’s interview was after your video here). Would love an update video from you, commenting on that. :-) Love ur videos. Thanks 🙏 😊

When you take the probability of life creation and then the fact that we've spent less than 40 years looking for planetary life, have discovered only a minute fraction of planets in foreign solar systems and then looked in depth at even fewer of those possible planets, I'd have thought it almost impossible that we've found a plant with life on it.

When taking into account what it took for this planet to host life and what it took for life to arise here, the probability that we will encounter any other life is astronomically low.
