Humans: We're going to colonize mars!
Venus: No, wait! I'm ALIVE! Love Me More!
Yes.
I would imagine it's the opposite, after seeing what we've done to Earth and all the life we share it with.
Any planet with life should be studied from a far.
@@cosmicrider5898 avoiding biological contamination would be of the highest importance if we are to reliably study a life bearing planet.
Humans: We're going to colonize Mars!
Venus: Good, we are going to colonize Earth then!
Honestly would be hilarious if the first life discovered outside of Earth is from Venus since we originally thought it would be like a rain-forest or whatever beneath the clouds, then inhospitable, wrapping all the way back to finding life there (even if it is in the clouds)
Vermin from Venus?
Looks like we just crossed paths. I was not expecting this lol.
He called us a wonderful person two times! 00:00 00:17
do they stack or cancel each other out??
@@voidremoved I can only assume they stack. We are wonderful of course.
Thats how wonderful of a person he is, i continue watching him because he is pleasant to learn from and very nice to us!
He is in synch, with his parallel Universe person.
Once for us Earthlings, and once for any Venusians who might be watching.
He called us wonderful person 3 Times ; - ; 0:00 , 0:17 , 3:00
Made my week.
We are quite wonderful
@@FranklinDelanoBluth999 debatable.
People called Sparky are even more wonderful than others too.. although I've never been called Lewd before :-)
Yeah...and I feel like I‘m really wonderful when he says that 😊😄😄😄😉👍👍
Made my week 3 times
I'm in the middle of a pretty bad depressive episode right now, and your "Hello wonderful person" made me smile. Thank you for being you :-)
You get through it bud. I've been there too and the main thing that helped me was talking about it to someone. It's hard but you can do it and people care about you
I second that. ☝️❤️
Many have been there. Me too. You are not alone.
I'm sending antidepressant vibes right now, brother!!
I struggle with that too.
Much love!!
@@tukayz254 You aren't helping. At all.
Glycine was produced in the 1952 Miller-Urey experiment using spark, water (H2O), methane (CH4), ammonia (NH3), and hydrogen (H2). Glycine was also produced in the volcanic spark and H2S-rich spark experiment. In fact the 2008 volcanic spark experiment produced 22 amino acids. Ref. Miller-Urey experiment wiki
Suggesting these compounds are produced by lightening instead of life forms.
This is a very important point. The glycine is not evidence of anything other than it has been found there.
@@negi9040 Both phosphene and a whole list amino acids under the right conditions are produced by electric discharge and maybe UV light. Seems be too hot at surface, may have been right conditions for life in Venus early age. Whether there's life is big question since precursor to life is produced even in space.
the comment I was looking for, thank you. Still very sceptical of this hype train.
yes, evidence that conditions in early Earth could result in prebiotic synthesis of chemical precursors of life was what was shown by the Miller-Urey experiment and many others that have been made since then. It's interesting to see this simple amino acid in the atmosphere of Venus (if its not another compound which has a similar spectral feature). At the end of the paper they discuss the possibility that Venus might be in an early stage of prebiotic evolution so if vulcanism or lightning in the venusian conditions can help produce glycine that would fit to this idea.
Last time I looked at Venus through my telescope, it was like looking at a tiny sun and it made my eyes hurt lol
How much zoom do you have, like could you look at Mars and see any details?
Hold on a sec......it looked like a mini sun!? How big is your telescope bruh?
Better look at it during sunset. If you look at it during the night it is way too bright
resembles a falling asteroid on Earth. Freezed in time :)
next time when you spot 2VENUSES in the sky...find a cover xD
Say it with me: "dirigible probe/drone". Leave a couple of communication/observation satellites in orbit and the dirigible is able to send 'daily' updates - including video and audio - back to Earth. This should be able to be made with 'nearly off the shelf' technology in the fairly near future....
Absolutely. Problem is, Mars is getting all the attention, with an unreasonable goal of Manned Mars missions in the near future - which leads to less funding for the less 'sexy' worlds.
@@dxps26 Manned mars mission > looking at satellite pictures of other planets
I’ve been thinking this for years! Let’s do everything possible on Venus, and everything possible on Mars. :-)
I would think the probe/atmosphere buoy should also be able to detect microorganisms in addition to video and audio, as these organisms probably aren't multicellular.
@@science.and.beyond Oh yeah. Lots and lots of atmosphere sampling. The video and audio is a nice plus to the true purpose of the probe.
Anton, your content is already educational but do you think you could make a introduction into the basics for chemistry and astronomy as well as what you believe everyone should know? I have learned a lot from you and I think the way you show and explain stuff would be a great way to not only introduce the next generation to this information but many others well into the future. Your content reminds me of when I was in school watching Bill Nye the Science Guy and thats a feeling I have not had in over 10 years. Please, stay safe and keep doing what your doing. You are a gem and everyone here cherishes you. :)
Bodybuilders are going to be so *happy* about this news! 😂
LOL. So clever
It might not be life yet but it could be the set-up for that possibility.
Plot twist, the Russian probe that first took pictures of the surface actually seeded the planet with life
Exactly what i thought from the start of life on venus scam started.
Literally just plot... no twist lol
@@BeginTheCrusade yeah but i would let it slide. Soviet union starting a selfsustaining colony and pushing humans forward from ze past would be such a 2020 thing
Mic dropped.
I was thinking this once Anton started talking about the equatorial winds of Venus.
Nice reconciliation : From "venus flytrap" to "venus update" :D
We know what channels you watch!
*segue
Our understanding of life is so limited in general. We once thought that life couldn't exist without Sun light. Now we know it can thrive biochemically underground and under the oceans. Dr Carl Sagan suggested that life would be very different than we would image on other planets.
absolutely, but we have to start with what we know at this time which is carbon based life
I once had someone tell me lifeform could be as anything that goes against entropy. Life will be similar to life here.
@@yourmaw6839 I agree
@@yourmaw6839
Life does not go against entropy.
@@tukayz254 you're right, my statement is a logical fallacy.
Your new camera setup is fab!
Thanks for uploading.
Sounds like it's time to put some satellites in Venus' orbit. We've left our guard down on our neighbor for far too long.
Should have satellites around all of them. This "whatever someone thinks of" approach is pretty patchy at best.
Many Satellites have already been sent to Venus. However, not many of them survived Venus' extreme conditions.
Balloons
@@jirehchoo2151 They were landers not satellites
It's time to put life in the atmosphere of Venus! We have life on Earth as we know it and we already know that certain bacteria can live there... Micro nova is going to stir up everything in the Solar system first, but after that we can experiment all we want!
Venus was always more interesting than Mars.
Edit: One looks red, the other one is on fire 🔥
Blasphemy! lol, kidding
Mars is overrated XD
Once we decide to terraform, Venus is more logical than Mars to inhabit.
Maybe, but Mars is more interesting in the sense that it would be A: More useful in its current form. B: Mars is easier, you don't need to reinvent the wheel, just improve the tech we used on the moon and we are set. C: Venus only makes sense as a research place, until we terraform it enough to get to the surface, on Mars you can do a lot more.
@P C been saying just this for years...no one ever listens...but now there is that light on the hill!
What if the life came from the Venera probe? That would be wild
That could be a possibility but it has really low chances.
I'm somewhat convinced that, if there is life on Venus, it's because we accidentally sent it there on one of our older probes.
@@TheAmazingCowpig yeah lol 😂
@@xviper0042 You are severely underestimating the ability of microbes from a tabletop to survive in a CO2 environment...
To me, that would show just how tenacious life is, and how quickly it can adapt and grow.
Much love
Anton I love how your coverage is objective and you don’t succumb to clickbaity speculation for views. Never change that my friend.

hey Anton I can't help but notice how lately a lot of science news fall to the easy trap of talking about non-peer reviewed papers and their ''implications if they were true'' and I have a very weird feeling that it's just fostering science fantasies rather than push science forward. I feel like current science headlines are pushing you to cover almost fringe subjects to make sure you get decent views.
I hope I'm wrong. Someone is probably gonna reply to this with a 3000 words essay on why I'm wrong.
Nope you are probably right!
It's a regular circle jerk
Pretty much all of science news is something like what you are talking about. Even peer-reviewed science papers, taken individually, may paint a very unrealistic portrait of science. Too often there seems to be a focus on one interesting finding or paper alone without reference to how it fits into the ocean of research in the same field.
Sadly this seems to be all media these days. Clicks are more important than reality now
Could be all of the planets contributed something to earth. Octopus and pltatapus have no explanation in the evolutionary record. There are other isolated life forms. Who knows?
Hello wonderful Anton. I love your videos and am glad you have found stable housing! This community is great and you're awesome. Keep up all the superb work that you do. Your videos are important!
Such amazing research that you show us on these videos.
Thank you Anton!
Ever see Tarkovsky’s Solaris (1972 not the remake). Glycine, neurons, life in the atmosphere... Venus is Solaris, tread carefully!

Great video with explaining images. Thanks Anton and team.
Quite intriguing. Keep up the excellent work Mr. Petrov. Cheers.

I have been watching you for a long time and I'm still amazed that you can make a video of this quality every day. You are a wonderful person. Keep up the good work.
Good ole Anton. This is all I needed to place my money on life existing on Venus, even if microbial. If I had to bet, something is there. The odds lean towards life. Our denial leans towards nothing, always!
@@comedicsketches You mean the conclusion that denial leans towards nothing, always. ? I'll have to look into some sources to cite on that like the first step in an addiction.
.
As for betting that some life is on Venus, it's not really a conclusion but the odds look good in my opinion. Anton did a video on the pioneer missions data. Really great stuff. I'm an optimist on the subject of life elsewhere so maybe I'm wrong but maybe I'm not. ;-)
@@comedicsketches Easy killer. I'm just hoping it's life and having a good time. My bet isn't a published scientific paper. Probably not life but dang you're killing the buzz of the possibility. When we do find life someday, even with concrete proof, we'll still be in the first stage of denial.
@@comedicsketches I meant to also say that of course a bet is a gamble. Gambling can cost. If a non biological explanation is "at least as likely", then you're saying 50/50.? Then I'll bet you 1 public apology in this thread and accept your "1 told ya so statement", with respect... against your "you took a gamble and were right", public statement in this thread respectfully. I'm fine with that.
Good luck.

Beautiful.
Comment section be like:
Anon: "Yey! Alien Life on Venus!"
Random Guy: It came from earth.
Anon: HOW?
Random Guy: The Soviets sent a series of unsterilized probes in the past.
Qanon?
Trust me that life is been here well before the Soviets
If it turns out to be true that life on Venus is from humans inoculating it by imporperly sterilizing their equipment, that will be pretty dissappointing.
On the other hand if Earth bacteria can survive and thrive on a goddamn Venus of all planets, that would be pretty incredible.
Dr Becky has a video about this. She actually chats to several actual scientists in the video. They all conclude that life we know about on earth would not survive the atmospheric conditions on venus, and even if they could, they'd be unable to reproduce and therefore evolve their.
That's actually unlikely to be the case. Firstly, the amount of time since the Soviet missions to Venus is insufficient to produce the quantities of phosphine we've seen. Secondly, no life on earth is capable of surviving in the conditions of Venus.
Good video, Anton...as usual.
Looking good Anton! Stay strong
Really interesting. I'm curious to see how life changes Venus climate - I mean, in case there is life after all. 😊
There might not be, but maybe there once was!
The chances of life on Venus are like 0.01%, and that's actually an over estimate.
@@krillin6 Well, life as we know it anyways. 0.01% is still quite alot.
maybe LIFE will make Venus rotate faster Same as talibans are doing here on Earth
Venus will just burn them alive
All these worlds are yours except Venus. Attempt no landing there.
Use them together, use them in peace.
No worries... nothing can survive the surface anyway😊
E
Because you told us not to we sure will..
The key is to not land there, just float along in the air there up really high
Do you have a new camera? The video quality is suddenly really good, love the videos 👌
6:08 - Hadley Cells transfer heat away from the poles, which is even present in the illustration you used. The air near the surface does flow towards the equator, but that is colder air on its return journey.

-new resources added to terrain generation
-gas physics engine updated
-preparations for the venus samples quest

Great video Anton!
A well nuanced capitulation of the search for life. Admirable restraint. Thanks, Anton.
I agree with what you said at the end of the video. I am, as any other one, very excited about the phosphine discovery, but I fear that people will start to look for more clues instead of practicing the scientific method.
Its 2020...science is just a term used for facts that back up what we want reality to look like. All other facts are meaningless.
The good news is that the recent studies are bringing much needed attention to Venus that it hasn't gotten in decades, despite being closer and having more chemical activity than Mars. This added attention means more scrutiny. The "high" might be strong now, but if there is room to debunk it, it will be found and relatively quickly, with how quickly the interest has risen in just the past month alone.

Chemical reactions that yield Amino acid generally run “downhill” thermodynamically- ie they are favoured with respect to energy shifts and stability.
This is why you can produce amino acids so easily in a test tube.
Going from amino acids to protein is not thermodynamically favourable. You need a catalyst such as an enzyme or solid interface to facilitate the reaction. (Or a long long long very long time)
The Miller-Urey experiment in the 1950s simply sparked some Water, H2, CH4 and NH3 in a test tube and numerous amino acids were produced (among other things)
Wouldn’t surprise me that amino acids are present in many bodies in our solar system - after all amino acids have been detected on asteroid fragments
(But they have never found proteins or more complex bio-chemicals)
I love when you do videos on our solar system
We’re on the right track guys!! Don’t jinx this.
I can't imagine a mission to Venus would even be that expensive.
Ikr, even the soviets could do it
It's actually more expensive than a trip to Mars
@@wintermiller4845 but it's closer :o

Sweet logical science. This channel is my happy place in 2020.
Extraordinary claims require extraordinary evidence. I like Anton's emphasis on "possibly but not necessarily"
Your voice is pleasant
Imagine the lindinburge only on Venus something like those oil rigs a platform on large pillars would be better
Valiant Thor, has been here to help. Somehow we said, “ no thanks”...
Im pretty sure in the paper that they metioned the method of generating phosphine from phosphoric acid. They stated that it could be contributing in someway but the levels measure are orders of magnitude greater that would be expected from this mechanism.
My guess is Venus, Earth, Mars all had life or life supporting atmospheres then an object hit the cloud thing in deep space causing a meteor shower to wipe out Mars and Venus and cripple Earths atmospheric pressure causing dinos to all die off
Sugestion: We first learn what is happening, and then we decide if it's sensible to bring back a sample.
To learn what is happening we need to bring a sample home
Are you sure we can go in that direction toward Venus?
Let alone return from the moon or Mars or further
I know they said they landed a man on the Moon.... However can you prove they came back, the original explorers?
I don't think so the orbital of all the planets is basically debris following the Sun around a galactic core

Glycine is pretty ubiquitous isn´t it? Has it been detected in the interstellar medium?
Lol why would you comment with a question when you obviously haven't watched the video, anton clearly says yes glycine has been found on multiple comets and asteroids..
@@lanceharper4107 they just commented before he said it
Phosphine has also been detected on other celestial bodies and in large quantities, but is easy to explain through non-biological means. The point being that Phosphine's existence isn't what is interesting, but rather where it exists and in what quantities. Glycine is in the same boat, where the circumstances of its existence make it interesting, not the mere existence itself. The detection of Glycine in the Venusian atmosphere is oddly correlated with the detection of Phosphine, both in its location and in its distribution. This SUGGESTS that their origins might be related, but that could just be a coincidence.
Either way, it is cause to look harder at the data. This extra scrutiny might actually disprove the previous findings, so even more reason to dig deeper.
You sure someone just didn't forget to wear gloves when handling the probe?
Pre probe data has shown signs of phosphenes upon review. So maybe no?
Bruh, nothing can survive the amount of chemicals used to clean these space probes haha
Anton did a good job in this video of calming down the hype about life on Venus. Early days still.
Good Job covering this sir, got me to thinking that one of the issues of the genesis of life on earth is how to free N from N2 in order to produce amino acids. On Venus that should be very easy. Now we need to add some kind of stabilizing organic chemical to get random molecular interactions together long enough to build complex molecules. Personally I belong to the lipid droplet cult, now I will go to work seeing how a droplet could form in the cauldron of Venus atmosphere.
Yeah, I almost think venus is a better bet for colonization than mars.
Assuming we have the capacity to mine resources from the surface, which is a somewhat tall order.
Though, I wonder what conditions are like beneath the surface? Initiating a mine might be tricky, but relatively straight forward once it's established.
It's my assertion we can't go toward the Sun Venus Mercury because of the solar wind we don't have enough horsepower to Buck that monster
@@richardshane456 the sovietss went to venus in 70s, I'm sure we can handle that. Being closer to the sun is also an advantage over mars, because solar power would be astronomically more powerful, even more so than earth. As far as the asteroid belt being an economic base for colonizing mars....um.... there's whole fucking planets worth of resources on the surface of mars. It would be centuries before we would even need to consider something like asteroids, unless you wanted to put them into earth orbit to make mining easier for earthlings, but my vision for a martian colony is pull a 1776 as soon as possible.
Maybe, but Mars is more interesting in the sense that it would be A: More useful in its current form. B: Mars is easier, you don't need to reinvent the wheel, just improve the tech we used on the moon and we are set. C: Venus only makes sense as a research place, until we terraform it enough to get to the surface, on Mars you can do a lot more.
"Assuming we have the capacity to mine resources from the surface, which is a somewhat tall order."
Getting to the surface is a big problem, electronics just die on Venus, no way to get around that. That's why Nasa is designing a mechanical robot to Venus without any microelectronics.
Venus would be very interesting once we terraformed it, cause it's a lot like earth, but terraforming Venus will be very hard and before that has happened you can't make a lot of money from it. Mars, on the other hand, has enough resources and scientific benefits to make it worth while.
searching all over town endlessly meanwhile they are serving life soup right next door. wild.
one important thing a science teacher told me for graphs is that correlation does not mean causation, and in this case that is very true just because that graph has a strong correlation, that doesn't necessarily mean theres life.
The thing with Phosphane generation is, while it can be produced by inorganic means - including the volcanic eruptions. But it also decays rapidly. Especially in atmosphere. And by the time phosphane from volcanic eruptions would get to the altitude where it was detected most of it should have decayed.
So the high count detected in the atmosphere is either because the surface-level generation goes more intensively that antocopated, or because the phosphane decays slower that anticipated, or something else is generating phospahne in the atomospere.
Imagine we find life in venus first and we were in the wrong focus on colonizing a planet
Just because life exists somewhere doens't mean we should colonize it. In fact I'd be ethically against colonizing a planet with life on it.
In terms of difficulty, Venus would be a whole lot more complicated to colonize than Mars, even though the distance to Venus is shorter. You can't land on Venus. Well you can land, but it would be a death sentence.
If Venus has microbial life in its upper atmosphere that’s pretty cool. But it doesn’t change that fact that the surface of the planet is an oven/ pressure cooker. If you wanna colonise Venus it’s gonna be a Star Wars Cloud City knock off. We’re better off terraforming Mars. Although, the biggest problem with Mars is the radiation.
The survival of humanity is paramount. By colonizing another planet, we increase the odds of preserving humanity greatly. I think that because of this, colonization should take priority over discovering extraterrestrial life.
Well either way its gonna happen since we are gonna get too over populated in the near future and its an advancement on interstellar travel

I think you already pointed it out of Space Rocks having composition of the stuff. What was found on Venus is a Space Rock that landed there.
Ok but what about the other amino acids? Life cannot occur with just one amino acid.

Yeah saying complex life was dumb, so I just changed. ANY life cannot occur with just one amino acids. Even viruses that are technically not living need more than one amino acid to have it's host make proteins.
Hello wonderful person, this is Doosh Baggins... I love Anton's intro's
We need more Antons!
It makes a perfect sense close by planets contain similar surface chemical composition, but different chemical processes, for many reasons. Most important are distance from a sun and gravity, since temperature and time directly influence chemistry. It could be sun is pushing complex chemistry away from it's center, how and why is another matter.

They will suppress information like they do technology .. They release information when they feel they can get labor from us (MONEY) to discover something they have known about for 50 + yrs .. Scientific Grants = Scientific discoveries Conspiracy is the reality ..Now, Go ahead and roll your eyes ..
Please be life 👍
I like very much your videos and your explanations of such a diversity of subjects.
If I may suggest an improvement, it is very simple: it seems to me you keep talking around the subjects after having explained them very clearly.
So, I would see as a beneficial thing if you managed to be more centered on the subject and shorten your videos, say cutting 1/3 of the time.
Glycine is the simplest amino acid. It is also the only achiral amino acid. Due to its small size, glycine plays an important role in protein flexibility.
I was starting to think I wasn't wonderful today
RNA/DNA needs phosphorus. Does Venus have enough phosphorus for life?
That excludes the idea life can exist without DNA or RNA but another things.. That's one of the most amazing things with exobiology
@@arthemis1039 amazing or not, it has to fit with science, and a form of genetic material is necessary. Though we can get into silicon based compounds that would mean different compositions for genetic material, but I think carbon is high enough on Venus so carbon-phosphorous bonds still seem like the most viable option.
@Thomas Chrombly Sure. Tell me how phosphine becomes adenosine triphosphate, which is the important part of RNA/DNA.
@Thomas Chrombly The devil is in those details you don't know about.
Great vid!
9:53 what song is that in the background? Good video as always anton!
We're looking for earthly life tracers here. There's a good amount of observer bias involved
Yes, but actually no. You don't look for something you don't know exists, there is a higher chance that life just like us exists than another form of life. Carbon chemistry is the best chemistry our universe can produce, other forms could exist, but they aren't as good/favourable as Carbon.
@@teaser6089 I see. Where does the boundary lie between having some complex hydrocarbons that resemble the ones we have in our genome or proteome lie and making a statement about present or past life?

@@timpeters7852 You are talking about "earthly life tracers" We only know of 1 succesful type of chemistry, so it's not worth looking for other types, especially when we aren't even sure if any of the other types could be practically possible.
So if we found other Venus or Superhabitable Venus they could be the real deal as far as we know now.
Amazing Vids!
3:30 this is the most humble and honest thing you could say here, you get a ton of respect points from me for being such a wonderful person.
We still don’t know nearly enough about Venus to jump to the conclusion that “it has to be life” total Occam’s razor situation.
We understand so little about the Venusian geology that it would be rather silly to just rule out the possibility of replenishment through alternative methods
It would also be rather silly to think that it is NOT life, which would mean completely throwing out everything we know about chemistry and assuming something we've never seen before is happening in Venus, which is almost less likely than it being some form of life.
PaxTV to assume even bacterial life though is not the proper way to go about this, especially since the ONLY life that we know of, the very existence of it, relies on hydrogen in some way or another.
Keeping in mind the Venusian atmosphere is a mere .002% water vapour, that leaves very little room for any form of life to take off, that we currently know of.
Go with the answer that needs to assume the least, that answer from my viewpoint is this is likely some form of as yet to be discovered geological activity, the surface there from what we can see is remarkably different than ours, so we can’t base our understanding 100% on the geological activity of the earth.
But if you want to believe it’s life even though that’s a huge assumption to leap to, you will believe just that, there’s no changing someone’s viewpoint in a CZcams comments section.
I’d say remain skeptical, but I think you need to become skeptical to begin with, so I’ll leave that in your hands
