If Venus and Mars tried harder at school we could have had 3 Earthlike planets. Imagine how much of an incentive space exploration would have if Venus or Mars had a rich biosphere with millions of alien plant and animal species to study, maybe even intelligent life? I once had a dream Venus was full of Koffing pokemon.

Those yellow photos of Venus have stayed in my head ever since, so mysterious and haunting to think that we actually landed a craft there.

I never even thought about this but… imagine a solar system like ours but with life on TWO planets simultaneously evolving separately from eachother. Imagine looking at mars satalites for the first time and see animals and trees. Wow

It’s interesting to hear the depiction of Venus being a tormented planet instead of an evil twin to earth, a place that simply couldn’t control its own fate rather than actively trying to be hostile

I admit it, it was me. I'm sorry.

Venus could have an entire fossil record of life that evolved independently from Earth that could’ve been destroyed during Venus’s runaway greenhouse effect. If that’s the case that’s such a tragedy for science, imagine what could’ve walked the surface of Venus.

127 minutes for Venera 13? That's a lot higher than I would have guessed. I'm surprised and impressed.

This paints a nightmarish picture of a world whose plate tectonics ground to a halt prematurely. Maybe life continued as normal for a while, but then half a billion or so years later the magma pressure built up to such an intensity under the entire fused surface that it burst through the lid in a single catastrophic release. It's like that firework display where everything went off at once instead of in sequence. All the volcanic activity that would have happened slowly on Earth over billions of years all happened at the same time, leaving a charred, dead, blown-out world with nary a shred of evidence that it had ever been otherwise.

I had the pleasure of visiting Parkes observatory in New South Wales, Australia. There was an astronomy enthusiast event at the time of our visit. It was a sunny, clear day and one of the enthusiasts pointed out Venus, shining bright in broad daylight. I ended up observing it through a telescope and was stricken by the sight of this amazing planet.

When you said "we're incredibly lucky to have a planet like Venus so close by," and gestured off-screen, I half expected you to be like "And here she is, right here in the studio!" Anyway, love your videos, love your energy. Keep it up dude 👍

I've often pondered what it would be like if Venus, Earth and Mars had all developed life and were each still thriving. Unfortunately, if there were lifeforms that developed anything like we did and were equally as intelligent and advanced as we are, we'd surely be at war with at least one of the two planets because that's just what we do. And yes, I'm fully aware of how unrealistic that is but, technically, it's not entirely impossible. Of course, when I get to thinking about that kind of stuff, I like to wonder what it would be like if Venus, for example, was still in the condition to support life and had also developed dinosaurs (but not humans) somehow and hadn't experienced an extinction level event, therefore leaving these hypothetical "dinosaurs" to continue to exist there to this day. Yeah, yeah, that's pretty unrealistic as well for so many reasons, but again, not entirely impossible. I honestly find these types of things pretty interesting to think about, personally, and even somewhat fun to imagine literally countless scenarios, realistic or not. Somewhere out there, though, there may very well be a solar system with multiple planets that each developed life in very different ways and the thought of actually seeing that is exciting, even though I'm fully aware that it's not something that I will actually ever get to experience.

I can just feel your passion when you speak about different topics. It’s great to see we still have people out there pushing the boundaries of humanity.

It would be interesting if there were a time in the past when Venus, Earth, and Mars all had water oceans at the same time.

Among the valuable lessons from Venera probes is that #13 is not bad luck, since Venera 13 lasted longest. Just putting that out there…

Quoting Boromir to explain the severity of Venus. It’s because of things like this you are amongst my favourite UKpostsrs. And my absolute favourite person on the platform. Skill, knowledge, in-depth research. passion, emotion and a true love for what you do. You’re a diamond amongst the rough ❤

Venus is so amazing. I know we've been very centered on Mars, but there's so much we can learn from Venus. Every planet we investigate will give us that much more of an edge at deciphering exoplanets.

Sean Bean's rendition of Boromir's horrifying description of Mordor, addressed to the Fellowship in Rivendell, is so appropriate, so gripping, so authentic. What a great actor -- the finest Sheffield steel!

One does not simply walk onto Venus

Remember, next time you look up at the night sky and see Venus. It's the closest you'll ever be to another planet in your whole entire life.

This sent chills down my spine I'm not even joking No matter how hard I try to familiarize myself with space, it still terrifies me sometimes...

Iv always wondered if Venus had a moon how much different depending on the size and location how much it would be different.

I’ve said it before. This channel should be required viewing for every citizen of this world. It really is the best channel on UKposts that exists. That’s my opinion and I know I’m not alone in that.

The more we study planets like Venus and exoplanets the more it becomes evident how unique the Earth truly is. The Earth too has gone through periods of extreme volcanic activity and yet natural processes on Earth has rebalanced itself to create a happy medium where life continues to flourish. Mars and Venus are also constant reminders of the Earth's fragility and the precariousness of our own existence. As always a beautiful and thought provoking video!

Is it possible that the key difference between Venus and Earth is that Earth happened to evolve not just photosynthetic life, but also life forms that create calcium carbonate (limestone), and Venus didn't? I'm not talking about the Gaia hypothesis per se, just the idea that Earth got lucky: the life which evolved on it happened to stabilize its temperature as the sun got brighter. Relatedly, it would be really cool if you could do a video on the silicate-carbonate cycle sometime. On Earth, there's about 10,000 times as much carbon locked up in limestone and other sedimentary rocks as there is in fossil fuels, and about 100,000 times as much in sedimentary rocks as in the atmosphere. My guess is that no planet around a sun-like star could remain habitable over the long term without a functioning silicate-carbonate cycle, but I'd love to hear your take on it!

I don't know what it is about Prof. Kipping. It has to be that hypnotizing voice. 😂 Always amazing, thoughtful content explained to perfection. 🎉

I've just watched The Fellowship of the Ring on cinemas less an hour ago and I definitely didn't expect to see a part from that movie again

Another great video, as always! Just want to point out that there’s a private mission to Venus coming up in early 2025, called the Venus Life Finder. Looks like it’s a partnership between Rocket Lab and MIT’s Morning Star series of missions. They’ll dangle something called an autofluorescence nephelometer to detect organic compounds in the clouds.

I’ve always been intrigued by Venus. There are so many questions and terrible conditions that try to stop us from finding answers. Thank you for this awesome video.

Another beautiful, haunting video. Venus is a fascinating world - such a beautiful name and appearance, for what turned out to be such a hellish landscape. I wonder what caused it to rotate backwards?

All your videos are very well put together and always leave me with food for thought. Thanks for the content

It is interesting to consider the idea of living things in the clouds of Venus. Have you considered the possibility that it might reside underground instead? Maybe there are water reservoirs beneath the surface like on Earth, and life has been able to survive the hostile surface through avoiding it entirely. Just a thought.

you are so darn good. I've watched a number of other programs about Venus but yours is always so much more in-depth and easy to understand

Outstanding video… answered quite a few questions that I’ve been too lazy to look up for years. I look at Venus everyday and contemplate… and doing so has enabled me to grasp how ancient people assumed these bodies to be deities. It’s a cool world. 😆

What a refreshing change from all the click-bait "science" content on youtube. Glad I found your channel.

Man I always leave these videos wanting to study these subjects more. Thanks for the content Prof. Kipping and the rest of the CoolWorlds team :)

Someone left the stove on...

Venus reminds me that life is short. We must work hard and cherish every moment, as everything eventually comes to an end. I loved the video! I understand that your schedule is quite busy, but I kindly request that you consider sharing at least one more video before 2024. Even a shorter video would be greatly appreciated. Thank you for sharing such an insightful video.

Your videos have ignited a passion for science and the mysteries of the universe within me. Thank you for being such an incredible source of inspiration.

You talk about Venus as the anomaly that went wrong, comparing it to Earth. Might be the other way around. The gigantic impact that created the Moon has sent to space a big part of our mantle, which had a short opportunity to outgas a lot before falling back on Earth. That is something quite obvious in the Moon sample brought back by Apollo. Without it, the Earth volcanism, atmosphere and ocean level could have been very unlike what we experience today.

I read one a theory about the resurface event: Venus had oceans, but they started to evaporate. As water is a even more potent greenhouse gas, the planet heated even quicker. This basically lead to temperature so high that the crust melted. The water in the atmosphere than reacted with the lave ocean, thus splitting it in hydrogen and oxygen. The oxygen reacted with the molten rock, and the hydrogen left into space.

Hello Dr. Kipping‼️ Justin Hays here, watching from Huntsville, AL. Better known as "The Rocket 🚀 City" and home of the U.S. Space and Rocket Center. Just wanted to say thank you for your work and for sharing your content here. I'm a huge fan and your channel is absolutely one of my favorites on UKposts. Keep up the great work. You Rock Man‼️ Stay Cool 😎

You have such a great channel here. Great job and keep up the hard work!

One of the views of the Electric Universe is that Venus is actually a fairly new planet having recently been ejected by Jupiter. That would explain the toxic atmosphere and so forth.

I've only just discovered your gem of a channel and I'm already hooked. Amazing, educational and such well put together videos! Awesome stuff!

I wonder if Venus would be easier to terraform than Mars. At least there are lot of raw materials in the atmosphere. I also wonder if it has any metals or fissile elements on or near the surface.

It's a bit creepy to imagine early life forms evolving on early venus at roughly the same time as was happening on earth, and then they just...never continued. Their planet, their home, just became hotter and drier for hundreds of millions of years until it became uninhabitable. It's creepy to imagine what early venus looked like, knowing what would become of it eventually.

A fascinating investigation, beautifully made and narrated. Thank you very much for this upload!

Never has there been a time where the words of Tolkien were more beautifully and effectively used

Fascinating and engaging stuff, as usual. Thanks Dr. Kipping for putting together these thought provoking videos, please keep them coming, my favorite channel on You Tube, and I watch a lot of stuff!! ♥🌎

Easily the best and most vivid description of the nature of the Venusian history, surface, and atmosphere available. So appreciate your passionate presentation of the material; captivating to the last moment. Thanks for such an accurate, well-designed, and executed video.

Venus has always deeply fascinated me, and I'm glad it's finally getting the attention it deserves again. Your smooth voice delivering eloquent poetic prose about it is an extra bonus.

I absolutely HATE it when people say things like this: "Nobody really imagined how much worse it was when the Mariner space probe made its approach in 1962" Bullsht. Someone actually DID imagine. And that person said as much. And the consensus rejected this assertion, without evidence, and even staged an attack on this person in an attempt to impune his character publicly, though they failed and only served to STRENGTHEN the original claim. The person who rightfully imagined the actual conditions of Venus was Immanuel Velikovsky. And the attack that failed was led by Carl Sagen. But Velikovsky developed his notions about Venus in 1949, and published this theory in 1950 in a book called "Worlds in Collision". The central thesis is that our present Sun was not our original Sun. Originally, what was called "Ra" by the earliest Egyptians was interchangeable with "Saturn", not the Sun. Though this era actually predates written history. The first Egyptian writings were recording an earlier oral tradition. Yet, by the time that this was first recorded, this era was already long over. Further elaborating, Velikovsky unearthed what he felt was a code left by some of our earliest ancestors. And across the globe, virtually ALL myths speak about a "before time", which both referred to an earlier era, but also meant before "time", or before the counting of days. Nearly all early myths globally also focus on water, sometimes even referred to as a mist, a haze or a fog, and then the transition to the time when the counting of days began, or the beginning of time. This usually coincides with a separation between the waters and the land, from the previous ambiguous state. With a reference to the similarities between myths globally, Velikovsky reached the conclusion that Earth was a planetary body that orbited Saturn, and Saturn was a Brown Dwarf star. The earliest myths describe a point within human history, but before recorded history and the rise of civilizations, when the Saturnian system became gravitationally captured by our present day Sun, and the spectacular upheaval that resulted from this event. But this idea was so disturbing to the Cosmological community and their fundamental claims about the formation of the planets, all at the same time, all from the accretion disc of the Sun, that they flatly rejected it. However, as a result of this catastrophic realignment of our planets within a new gravitational regime, Velikovsky stated that in an effort to suddenly adapt to these major gravitational changes, Venus initially did not exist. It instead was a huge chunk of mass ripped out of Saturn in Saturn's attempt to reach gravitational equilibrium. Venus, he said, was actually a new planet. The people who attacked Velikovsky's theory predicted that Venus, as a member of our solar system with an age equivalent to Earth, would have a surface temperature that was roughly equivalent to that of Earth. Perhaps a bit hotter due to its proximity to the Sun. But Velikovsky predicted, based on his hypothesis, that Venus was not just hot, it was very hot. If I recall, I think that his prediction was in the neighborhood of 600 degrees Fahrenheit. THAT'S where this story ACTUALLY begins, because there WAS someone who imagined the inhospitable state of Venus, including its extreme temperature, although it was actually hotter by about 200 degrees Fahrenheit than even Velikovsky predicted. Velikovsky also made some predictions about atmospheric conditions. But what is truly remarkable is other things that we have only recently discovered. For example, if the earliest myths describe Saturn as our original Sun, then we would have been orbiting through the mist of what are now Saturn's ice rings. The stunning revelation that I believe was first made last year is, due to its current position in the solar system, the water of Saturn's rings should be different from the type of water that we have on Earth. Amazingly, we have found that Saturn's water is identical to the water on Earth. Another very obvious point of agreement with the hypothesis is that of gravity. At the time that the vast array of dinosaur bones were discovered in the early Americas, the first Paleontologists knew, it was obvious that creatures of such mass could not exist with the gravity that we experience today. Even Leonardo Da Vinci has a calculation that shows the extreme bone mass that would be required to sustain the body of such a massive creature, and the proportions are absurd and certainly don't match the dinosaur remains that have been found. So, just at the most basic level, our present day gravity is too great to allow for the existence of the dinosaurs. At some point, the gravity on Earth had to have changed. Other prehistoric evidence exists of this planetary redistribution, but that is an even longer story. Just search for "Anthony Peratt Plasma Petraglyphs" - This is an amazing discovery that was made, I believe in 2006, that virtually no one knows about. This discovery reveals tons about our history. It explains the myth of Jacobs Ladder, Stonehenge and so much more. Even the formation of the Grand Canyon. But yes. If you allow for the possibility of Velikovsky's theory, then everything about Venus not only makes sense, it makes reliable predictions. And THAT is exactly what Science is all about...

This is a fantastic channel, keep it up

this pic of Venus surface has haunted me since i was a kid.

Oh wow, you actually cited your sources. I was skeptical that you would, as so many channels like this one just AI generate everything. But you seem to have actually put in effort! And I'm pleasantly surprised.

after watching this, I do believe that if there's ever a movie made about humans landing on Venus, it's going to star Sean Bean

Yes!!! After waiting what seems to be forever another great video!! Thank you :) Going to rewatch this one again and again like all the others!

I'm very glad there's new missions planned. We need to answer the phosphine question for one, but there's so many things we can learn from our disruptive twin

You are both scientist and poet. A million thanks for your incredible videos ❤

Venus is probably my favorite celestial body in the solar system. The fact that terrestrial planets all have the potential of going the route of Venus, while simultaneously remaining such a mystery to us, is endlessly fascinating to me.

Just made my Saturday evening 😊

I’ve always been so fascinated with Venus. Endless questions and curiosities. I do hope that we see more missions to our evil twin planet.

Amazing job as always with this video! A cautionary tale of the state of our place in existence. Also so many mysteries to unravel, appreciate, and learn from.

This video is brilliantly written, produced, and hosted! I just want to thank you for a video that has visited a sense of wonder upon a jaded old man like myself! I now want to see Venus in pictures, videos, and every type of analyses! Thank you again!

What the Hell happened to Venus? Idk. But now I’m going to find out

I as always love and appreciate your content. Some of the best out there.

Oh WOW. What a brilliant story. I'm not sure how you've done it but you've made this both educational and interesting. Bravo.

If our simulations for slow rotators is correct then Venus must have boiled off before slowing down, else it would likely be very habitable right now. Also interesting to notice Venus is dramatically enriched in neon and especially nitrogen compared to the Earth, even accounting for the different oxidation state it would have if it had oceans and free oxygen (which would have trapped maybe 1-2 bars of N2 in the crust). A denser N2 atmosphere might either have helped warm the planet through band widening or cooled it through Rayleigh scattering (hard to predict) but I doubt it would have been relevant to trigger the runaway greenhouse. Anyway, this makes me think the Earth lost a lot of volatiles during the Theia impact.

This is one channel I eagerly await new videos from. I don't do that for very many channels at all. Also, your appearance on Lex Fridman's podcast blew up! It had like 5.9m views iirc last I checked, that's so awesome!

It’s remarkable to think that the gaseous atmosphere is that heavy that it’s worse than having a liquid like water exert many tons of pressure at depth. It’s just hard to fathom how a gaseous atmosphere could even do that. One would think it’s just not possible and that it would require a liquid to transfer that much force. Incredible!

Funny seeing as your soothing voice is helping me through a very difficult moment in my life. Happy to have found these videos!

What a wonderful and educative video. Many thanks! Just an off-the-cuff idea: it would be interesting to know the isotopic composition of the crust/rocks/solid matter. I wonder whether we would find that Venus was disproportionately composed of particular radioactive material, the decay or reactions of which could account for the unusual proportion of deuterium being found?

Wow what a great documentary. Thanks! Can’t wait for your next one!

Thanks for another terrific presentation, David. Putting together Venus's retrograde orbit, young surface and huge amount of outgassed CO², a catastrophic giant impact seems most likely. Venus may have been a more reasonable world before being hit by a protoplanet. If true, it would suggest that giant impacts don't have predictable outcomes, and can yield either "trash" or "treasure". When I was young, I had so many dreams about what might be found on the Moon, Venus and Mars. I was gutted to learn that they were all utterly desolate. It was even worse than finding out that Santa and God were just myths. I'd look hopefully into the sky, unaware that interstellar craft won't have air traffic control lights, that biology and space do not get along, that the absurd distances make interstellar travel physically highly unlikely and economically unviable, a luxury only possible for GAI, if that. I still miss Moon men, Venusian jungles, Martian canal builders and flying saucers.

You really got my mind moving about Venus in a way that I have never felt before. Thanks!

Another fascinating upload from Professor Kipping. Venus seemed to be a kind of last hope on my terraforming list after Mars was portrayed as being too broken for this to take place there. Now the good Professor has removed all hope of terraforming Venus. Perhaps the whole idea of Terraforming is simply beyond us. Once a system is ruined by a catastrophic event, as with both Mars and Venus with their planet killing collisions, it is too late to do anything about it. Venus is a great educational tool perhaps put there by the great Engineer for our education. It is telling us that the habitable zone, or the idea of it, is never going to be enough and Earth like planets are going to be so rare as to be impossible to find given the vastness of the universe. We are truly alone.

I believe that Venus was exactly like Earth; it even had a 'moon'. Whatever struck Venus, it was powerful enough to alter its rotation, and send it's moon into another orbit. That moon became the planet Mercury. 😐

Bro wtf, I was reading Wikipedia's article on Terraforming Venus and its many Colonization options....talk about perfect timing

I feel genuinely sad that some people think space is a hoax. How sad and draining their life must be, that anything amazing or alien must be fake. It must also be exhausting to constantly have to make up excuses for why these things aren't real. I can't understand why these people do it, or what they gain from lying to themselves. To be at the mercy of the awe of the universe and its many amazing celestial bodies, has got to be better than any false sense of smugness and stability these nutcases feel.

The lesson is. If we can terraform venus, the universe is ours.

My thoughts: 1) The idea of Venus crust having catastrophically re-surfacing at some point in the past is quite a striking one. Either way it would have been incredible to watch this so-called 'stagnant lid' world's most dramatic moments. 2) The Soviet scientists achievements with the Venera craft is the stuff of legend and is deservedly celebrated. 3) There is a key episode of the BBC series, 'The Planets' (with Brian Cox) that I think is key to understanding our terrestrial worlds; 'A Moment in The Sun' - it's central thesis being that Mars and Venus each likely had their '....moment in the sun...' when they were habitable for a time in their early life. Mars likely lost its ice-clogged waters early on to gradual loss to space due to a lack of magnetic field, whereas any Venusian water likely led directly to its subsequent downfall in the form of the brightening Sun and the commencement of a runaway greenhouse effect. This episode is very important, I think it tells us that a major factor in consideration of habitability on any planet is the factor of time. How long can a given planet expect to retain key elements like liquid water at its surface? Earth has been very fortunate, rare perhaps, in being able to retain liquid water at its surface for such a vast period of time.

Thank you professor. The video was amazing as always!!! Your content is the best!!!

thank you for opening my world by your generous gift of your podcasts...your channel is a telescope to our wonderous universe

Sometimes your videos get so spooky!! This was phenomenal. Also, cool ultrawide!

I felt it was pertinent to mention that Earth has a moon, and a large one, and Venus does not? Seems like that’s a vital point when comparing the two

Very grateful for this video dropping on Sunday, when I could enjoy it and immerse myself into it to the fullest. Just 1 Question. Isn't our moon gravitational effect on Earth also a significant factor in keeping our tectonic plates from solidifying?

0:45 I think John Gray knew what he was doing when he wrote the book "Men are from Mars, women are from Venus" 😀

Venus doesn’t have the constant gentle tug of our large moon over millions of years, slowly pulling life up out of its crust. Like Earth.

Could the life exist in the atmosphere. It seems like your going to answer my question as I type it. I was so cool for like 10, maybe 12 seconds. Professor Kipping and your Cool Worlds crew, thanks for another excellent video. Off this subject. Is the new European space telescope array going to be a way for you to look for moons. I hope it is. Thanks again.

This was such a cool and well researched video. Subscribed! I always thought Venus was under appreciated planet - mars gets all the glam.

This video was very well done. Everything down to your tone of voice, descriptions of the different venusian geological features, to the possibility of life. I also really do hope to see NASA build a Venus lander, land on it's surface, and take 360⁰ high resolution pictured and possibly record audio like the soviets did. With modern technology that is very possible.

A great day and I come back to a new cool worlds video. Thanks for making it a greater day 😅

Hello cool worlds man! This video makes my closing shift worth it.

Been waiting too damn long for this one. These videos make me wanna bust

I feel like Mars gets so much attention I would love to see a mission to Venus. The amount of new think we would learn would probably be crazy.

I appreciate this relevant and actually helpful sponsorship. I will be checking Incogni out.

What’s crazy is we could easily have an outpost in the clouds of Venus

Curious as to your take on the retrograde motion of Venus on its axis, the only planetary body that rotates “backwards.” Surprised you did not mention it as a clue to one part of its catastrophic history of development.

The Sean Bean LOTR monologue to describe Venus (Mordor) was absolutely pitch perfect editing.

Fantastic and fascinating video,. There are very few comprehensive sources of infirmation abot modern theories about geological history of Venus. Thank you!
