If you rank the most habitable places in our solar system Venus lands pretty low, with surface temperatures hot enough to melt lead and sulphuric acid rain. And yet it may have just jumped to the front of the pack. In fact, we may have detected the signature of alien life - Venusian life -for the first time.

[@EebstertheGreat]

@@AverageAlien We don't know that life is impossible on Venus. The conditions of the middle atmosphere appear to permit life. We do know that lightning cannot produce enough phosphine on its own to explain the concentrations seen. (In fact, it's like six orders of magnitude off.) Probably there is some unknown abiotic process producing the phosphine that doesn't occur on Earth, but right now, that's pure speculation.

[@AnotherKid13]

@@AverageAlien Except that if you read the paper associate, the researchers have worked pretty hard to exhaustively calculate the different rates of phospine production, including surface volcanoes and lightning strikes. The amount of phospine observed is almost 4 orders of magnitude more than the expected rate, which almost always means something else is going on, be it extraterrestrial life or an unknown branch of inorganic chemistry.

[@durnsidh6483]

@@christianv-h3278 I was thinking about the huge amount of time on Venus when it still had continents and oceans and a milder climate. This lasted for hundreds of millions of years. That's why I consider that there may have been more complex life a long time ago on Venus, and fossils of this extinct life may exist.

[@christianv-h3278]

@@mstalcup Oh right, I get your point - so you mean that more complex forms of life would have developed on Venus in ways similar to the Earth? Seems plausible. If we take into account the currently oldest evidence of life (3.8 B years old), and the oldest evidence of multicellular life (3.5 B years old), that means it would've taken approx. 300 million years for multicellular life to develop. Which does seem like a reasonable time span within the time during which Venus was more habitable.

[@Jossandoval]

Why are so much people obsessed with the gummy bears? They are resilient, not extremophiles. That means that the tiny piglets are capable of surviving a lot, but not necessarily to reproduce and form colonies in extreme conditions. The difference with true extremophiles is that while resilient merely survive in order to wait for better conditions, extremophiles actually make a live in those conditions. On the other hand, an extremophile outside its natural habitat might die very easily, in which case it is not resilient.

On Mars it would probably be kilometers below ground so it would be far harder to access than the clouds of Venus.

[@Nuovoswiss]

There was a serious issue with their conclusion: the last "ruled out" claim on their list of abiogenic phosphine processes is unfounded and unsourced. Venus' lack of a magnetic field means it gets a massive amount of solar wind hitting its atmosphere, which is mostly relativistic hydrogen plasma. Their proposed pathway, whether *biogenic or abiogenic*, is based on the presence of (trace) phosphoric acid in the atmosphere of Venus. It makes sense for phosphoric acid to be present given that we expect Venus to have some phosphate minerals, and phosphate minerals react with sulfuric acid to produce phosphoric acid vapor at Venus' surface temperatures. Trace phosphoric acid would react with this hydrogen plasma to produce phosphine and water: H3PO4(g) + 8∙H(p) PH3(g) + 4∙H2O(g) The only thing they show to rule that out is a single unpublished (not peer reviewed) manuscript. You can find that manuscript on a pre-print server, and it does nothing to rule out solar-wind produced phosphine, it just has a single sentence saying "we don't think so".

[@RandomBoxOfWeird]

​@@enaidealukal4105 Idk I don't necessarily think this phenomenon is hiding any new science at all. Just to be clear - I'm not claiming anything, I'm just always skeptical when it comes to "brand new" or "groundbreaking" science in popular science reporting. There might be some already known chemical process causing our observations, just that we don't recognize it because we of course can't reconstruct the exact environmental situation present on Venus from current data. I'm not saying this isn't a worthy endeavour, just that it seems to me that the perception of science many people have is much flashier and more sensational than it really is "behind the scenes" (which I dislike, because it sets the stage for the Hyperloop and other equally silly sci-fi brainfarts) (Btw, even if it does turn out to be something really groundbreaking, I won't have been wrong in being critical of that assumption, since at this point, it might as well not be.)

[@arthianphoenix2331]

I am quite sure that quite a few people will be very disappointed at my comment, but I do not think we will find life on Venus. It is much more likely to be a different process either within the planets crust or on the surface that produces the phosphine the scientists detected (hats of by the way, detecting a chemical at 2 ppb using light bouncing through the atmosphere? I can't even understand how that is possible) Saying that, the chemistry here makes life quite unlikely/impossible. For a start, venus contains almost no Hydrogen, a simple molecule absolutely vital in the creation of DNA and all the proteins within the bodies of living Organisms. The lack of Hydrogen makes life as we know it impossible, and "other" forms of DNA that are still capable of self-replication would still need protein like structures to achieve this, at least as far as our current understanding of Biology goes. Secondly, the issue of the environment. Developing life is already hard. We still don't understand how life came about, but it is likely an entire planet (ours) covered in Organic elements and full with sources of chemical energy combined with an extraordinary amount of luck was needed to create the first Organisms. On Venus, the conditions for this never even existed. As far as we know, Venus once had a thicker atmosphere and an even hotter surface, but even if we forgo that and assume perfect conditions for life, it would need a very, very sturdy extremophile to thrive at these temperatures, not to mention the acid and the winds of course. And thirdly, upon reading the paper that was released, It seems as if th two scientists dismiss a couple of reasons as to why the creation of phosphine by a chemical process is improbable, but then immediately skip to life without giving that solution a proper critique either, which seems strange considering life is a far, far more improbable answer to the existence of phosphine. If you need to see for yourself, I advise either reading the document for yourself (I find the explanation of how they actually found the stuff to be facinating) or checking out Thunderf00t, a doctorate in chemistry and physics who explains why Life on Venus is highly unlikely

"The universe is full of life. But the universe is immense. And intelligent life living in the physical manifestation is scattered about a great and vast arena. It is concentrated in some places more than others. In some ways, it resembles the maps of your countries, where there are large areas where many human people are congregated, and there are areas where very few people live at all. Between these areas of great congregation, there are roads, great roads that are heavily traveled. In sparsely populated areas, there are very few roads, many of which are rarely if ever traveled. We want to give you this analogy of the dispersal of intelligent life in this Galaxy. We have never ventured beyond the Galaxy, so we cannot speak of the other possibilities. Yet within this Galaxy alone, there is such a diversity of life! We ourselves have only seen a very, very small part of it, for the Galaxy is very great. Your world exists in an area of congregation, an area that has many inhabited worlds. You do not see this within your own solar system, but beyond your solar system, this is most certainly true. You do not live in a sparsely populated part of the universe. You do not live in a region that is uncharted and unknown to others. This gives you certain disadvantages because your world is being scrutinized by many powerful forces. They are seeking an Intervention now because humanity has reached a point in its development where it has built the infrastructure that other races believe that they can use for themselves. This is why the Intervention did not happen at an earlier time. It was allowed for humanity to build the resources and the infrastructure first. In other words, you did the work for those who believe that you will serve them in the future. Therefore, you do not live in a distant and remote part of the Galaxy. This you must understand. Travel in space occurs along certain routes or avenues, just like in your world. Certain roads are heavily traveled; others are rarely traveled. Your world exists in an area of considerable travel, which means there are many races using these routes for commerce and trade. Here there are several emerging races such as your own, all being carefully watched by others." A quote from *The Allies of Humanity* books, which represent the perspective of a small group of ET beings consisting of individuals from those few free races in our local universe. They have been sent here to observe the ET intervention going on within and around our world and to report to us what they see and know. These briefings are a must read for all who are serious about the topic, and all of them are available free online.

Biologist note: I think the most acidic natural environment where we've found life on earth was a pH just above 0 (like 0.2). Googling, it looks like the region of the atmosphere of venus we're talking about has a pH of -1.5. That's about 15-20 times more acidic, but if I had to guess I'd say it's more likely than not that there have been organisms on Earth at some point in the last 4 billion years that survived at that level acidity.

It would be a hard hit to religion if we detect an extra terrestrial organism that has a variation of DNA that is sufficiently similar to ours to conclude that a common ancestor must be the origin.

[@EnglishMike]

The detection of Earth-like extrasolar planets (i.e. rocky, within the habitable zone) is arguably a bigger step. We have long thought they would be there, but being able to detect them and begin to study their abundance and characteristics -- perhaps even their atmospheres in the not too distant future -- will go a long way toward understanding our place in the Universe.

The whole idea of "life as we know it" is scientific, yes, but also useless, since we only have one sample planet so far.

[@Merennulli]

@@NesrocksGamingVideos It's not useless. It defines the type of life we have the biochemical knowledge to look for.

[@NesrocksGamingVideos]

It's useless because it narrows the point of view by an astronomically biased sample. There are billions of billions of billions of planets in the universe. Comparing all of them to just one of them is useless. Chance plays an obviously bigger role than that comparison. It is the most extreme case of sample bias.

Great video! Very informative. One scenario.. That upper atmosphere could have extremophile clouds that, over millions of years, have evolved neural net nervous systems. Amoeba-like clouds could furthermore have evolved reproductive and social systems similar to our own. They could be inhabiting our own earth clouds and observing us from a very stealthy location even as we speak. Their vaporous cosistency would make them undectable to our surveillance technology.

[@henriwilliams1136]

If this is confirmed as life it seems likely to me that it would have evolved from life on earth that would have travelled to Venus via panspermia back when Venus was a watery planet. However I hope it's not since having proof of abiogenesis happening more that once would be so exciting for life elsewhere in the universe and would likely mean we could find life in most solar systems throughout the universe!

[@supermaster2012]

It's as likely that it's the other way around. While Venus' greenhouse effect phase is relatively recent in geological terms, it's very likely that Venus harboured liquid water and a sensible atmosphere during Earth's anaerobic evolution stage.

[@ross-carlson]

I agree that discovering that abiogenesis has happened more than once would be a stunning revelation but don't understand how you can proclaim it's "likely" to be panspermia, what evidence do you have to make that assertion? Sure, we only have evidence of life beginning on a single planet but that's only because we've explored and understand only one planet. The correct assumption is - we don't know and until we know making assertions about what is or is not likely isn't very helpful. Instead we need to work out everything that can be falsified, as stated it is NEVER aliens until it can be nothing but AND we have evidence that it is.

[@supermaster2012]

@@ross-carlson you should learn to read before making facetious remarks. What I said is that Venus->Earth panspermia is just as likely as Earth->Venus panspermia since both planets exchange about equal amounts of material every year and they shared a similar environment for a pretty long geological period.
