Life on Jupiter!? Carl Sagan's "Crazy Idea"

[@lexibyday9504]

Gas giants have stability. A stable cycle of fast moving winds smashing tiny particles into each other. If the right particles smashed together in the right way maybe they'd still form an amino acid. And maybe those flying aminos could still evolve into life. Stable does not have to be calm.

[@Phrenotopia]

Exactly my point.

[@fedoralexandersteeman6672]

That is a very good summary of this video.

[@przemeklisicki8741]

How far down could the life go before dying? Their are organisms (even multi cellular) on earth living near hydrothermal vents or in underwater volcanose.

[@chimera9818]

@@przemeklisicki8741 I think it probably will depend, probably somewhere has low has the last point we get signal from gas giant when we crush satellite into them (considering life were shown to survive in places human technology have problems with like Mariana tranche)

[@hyrumhanson3390]

If the hydrothermal vent hypothesis for atobiogenesis is a way for life, a moon that erupts portions of an under ice ocean from time to time is a possibility as well.

[@Ditidos]

Gas giants fascinate me. I doubt there is life in Jupiter specifically, but it would be an amazing sight, perhaps even more than a gas giant devoid of life. I hope we can have manned missions to these distant worlds somewhat soon, the jovian system is fascinating. Also, is it possible that in a gas giant there wouldn't be cells in the classical sense? Then how could life go multicelular, if it even could do it. The next video could be very interesting, gas giant natives are such an interesting trope in scifi, probably because they are never humanoid.

[@LisaAnn777]

Manned missions? Oh good your our first volunteer to be sent into the atmosphere of Jupiter with a parachute and space suit! Now as far as getting you back....

[@Ditidos]

@@LisaAnn777 I was thinking more on the moons of these planets and people controling robots from orbit. But I do find funny the idea of just being somewhere in the atmosphere of a gas giant.

[@LisaAnn777]

@@Ditidos yeah I'm curious what could be living under the ice of Europa, even though the ocean would be vastly deeper that earth with it's low gravity it's thought to be not much more pressure as the Mariana's trench, which obviously we still see life there on Earth. I guess if you want we can send you down in a submarine if your not willing to skydive into Jupiter? Once again getting you back might be a problem 🤷

[@LuisAldamiz]

I remember that episod from my early teens, I just loved the idea, because why not? Think outside the box like good old Carl.

[@heroiccephalopod6459]

Gosh I just love your videos so much! I recently found your channel and you deserve so much more recognition for these videos!! Its so inspiring and I learn so much. Good work and thank you for these awesome and detailed videos!

[@violetlight1548]

The chapter on hypothetical Jovian life is still my favourite in the book version of "Cosmos" to this day! I've read a few science fiction novels that have taken this idea and run with it too, namely "Saturn Rukh" by Robert L. Forward, and "Manta's Gift" by Timothy Zahn (of Star Wars novels fame). I would love for this to be the case! Maybe then gas giants wouldn't be so often overlooked as places for alien life to evolve!

[@robdotgif]

This video awakened lost memories of seeing the cosmos episode as a tiny little stupid baby, thank you! Now I guess I should go re-watch the whole series cuz why not lol

oh my god yes. I'm working on a spec evo project taking place on what might as well be a gas giant. Finally, some more content. Edit: I feel it's worth mentioning life in a gas giant could not have the same biochemistry as earth life. Phosphorous (a crucial part of DNA) would only be a gas (between 0-100 degrees celsius) in highly unstable molecules, such as phosphine and phosphorous pentafluoride, meaning DNA as we know it is likely impossible in a gas giant. (I've gotten around this by just handwaving it, saying fluorides are not highly unstable, and don't readily hydrolise, having phosphorous pentafluoride knocking about the atmosphere in small quantities). Also if there were animals, their muscles would have to work differently to Earth animals. We use calcium ions which are attracted to oppositely charged proteins to move our muscles, but as far as I'm aware, there aren't any compounds that contain calcium that are gases at temperatures Earth life can survive at. (In my project, the animal-like creatures move their limbs using reactions between tiny amounts of hydrogen and oxygen, producing super heated, high pressure steam, creating pneumatic limbs) edit 2: Oh, the droplet cell idea is genius! That solves a lot of issues with my spec evo project's abiogenesis Edit 3: When I say the phosphorous molecules are unstable, I mean they'd be unstable in an atmosphere containing oxisiders (such as oxygen and fluorine) which (as far as I'm aware) are critical for life to exist

[@Phrenotopia]

Good points!

[@orbismworldbuilding8428]

There are alternatives to phosphorus such as (sulfer and arsenic) = PNA, not sure if thats any better here but it is a potential alternative.

[@orbismworldbuilding8428]

Pneumatic steam muscles could work. Im not sure what elements/chemicals are in piezoelectric materials besides the usual example of quartz. I think piezoelectric muscles and even pseudo nervous system could work though

[@Dragrath1]

Actually thanks to the work of Juno we now know the atmospheric layer of Jupiter extends over 3500 kilometers deep with the banded structure continuing all the way down in giant convection cells before coulomb drag cancels out differential rotation causing the planet to rotate as a rigid body. For a proper gas giant I don't think this leaves very good odds however gas giants aren't the only giant planets. Ice giants are much more enriched in heavier elements. Alas I fear complex life is improbable within any reducing atmosphere barring some alternative large net electronegativity chemical reaction with a sufficently long residency time in the atmosphere or other fluid medium.

[@Phrenotopia]

@Dragrath1 I can always count on you to come with several insightful observations and additions. Yes, my own intuition is in any case that an oxygenic biosphere is a much more likely state of affairs for life, given the higher levels of energy involved, even though I do not myself understand the physics and chemistry involved thoroughly enough. Many researchers have however argued that the Cambrian Explosion was in part driven by a sudden increase in free molecular oxygen triggered by geologic events heighting available energy levels. Therefore, I also don't have my hopes out for life in the frozen world of Titan. Lower temperatures seem to imply lower available energies, but the steepness of gradients may be more significant. Although I don't quite understand your point that a modern understanding of Jupiter's atmosphere has ruled out the possibility for life (apart from the fact that we cannot see it going on). Giant convections cells do provide some kind of cyclical stability for life to latch on to, theoretically speaking.

[@ChimpFromSpace]

The idea of tiny floating water droplets filled with organic compounds as a sort of "framework" for a living cell actually makes sense, and is very compelling.

[@radudancoroian5169]

Hello, I am an artist and I am working at my own speculative world, so I have a question: on a planet with high winds , how would flying creatures adapt to resist/avoid the harsh conditions?

[@krakenpots5693]

A smaller, or retractable surface area, in order to diminish drag, or wind resistance, a beetle-shaped exosceleton that would force the animal onto the ground in high wind. hooked feet, in order to grab onto foliage or whatever the creature uses as a perch. a hive-like structure where individuals would all huddle together in one clump in odrer to avoid dispersal. or a mix of all of the above: an long, thin animal with retractable flight surfaces that, when high winds ar inbound, lands in a group of similar individuals to latch onto the ground with five (or more, this is my imagination going, here!) specially designed pedipalps with hooks on them (that also double as teeth for catching prey). when thusly "rooted", they resemble a forest of palm tree-like creatures (I would like to call these Foinikapods). other smaller creatures could even evolve to seek shelter in these "Foinicades", maybe even going as far as developping a slightly symbiotic lifestyle, where these "Katafyplasms" might clean the Foinikapods of any parasites.

[@enchantedplayer6168]

I'm so glad I was able to find this channel. I've always had a fascination for the possibilities of extraterrestrial life, and I was dissatisfied just looking for life as we know it. It's great to see content on the possibilities of life in drastically different conditions to us.

[@inu9857]

I love your channel, i just discovered it a week ago and it's all a ever needed

[@thomasrdiehl]

I wonder if worlds maybe need to be somewhat hostile to life in order to carry life, so there is necessity for adapting to threats, kickstarting evolution.

[@zerkig9058]

I recommend reading "Manta's Gift" by Timothy Zahn, it's a bit like Avatar buy in a non-humanoid form. The life on Jupiter was described beautifully and in a fascinating way there.

[@gadielgonzalez2755]

I have a theory that gas dwarfs would be much better suited for life than gas giants. Not only are the atmospheres calmer and the gravity much lighter (which adds less pressure to the gases inside) but gas dwarfs can orbit closer to the goldilocks zone without having their atmosphere stripped away.

[@mechamudskipper]

HELL YEAH I love gas giants, I always knew someone lived there.

[@austindeang1407]

If the most likely culprit for the warm colors on Jupiter is sulfur compounds, what does that mean for the possibility and biochemistry of life on Jupiter? That although carbon-based, they'd have more sulfur compounds as part of their basic biochemistry?

[@Phrenotopia]

I believe Sagan & Salpeter argue for the reddish hues may be due to something *other* than sulfur compounds, and that that could be photosynthetic organisms.

[@austindeang1407]

@@Phrenotopia That could work based on what they argued, although the orange, brown, and yellow hues are likely to be ammonium hydrosulfide or other types of sulfur compounds, but I’m not sure if that’s actually been confirmed. They did say in their paper the causes of the brown and red coloration were organic compounds.

[@Phrenotopia]

@@austindeang1407 I mainly focused on Sagan & Salpeter's old paper, but took a brief dive into it, and from what I could gather is that there's still no confirmation on the exact cause of the colorations.

I believe this!! Interior Jupiter is so vast and has so many layers it could hide an entire universe in there.

[@zebonautsmith1541]

it's 2023; how can we not yet know the answer to this question yet? (Oh and Sagan is right)

[@reinatycoon3644]

the first lifeforms would have been extremophiles. That is because life is speculated to have first originated near geothermal vents where temps where life exists reach almost 200 degrees with intense pressures.

[@raffaellouis4326]

But why most scientists kept say'd life cannot exist on gas giants as always

[@Triliton]

Interesting, life could find a way

[@BdogFinal14]

The first flawed assumption is alien life forms must follow the same biological parameters as life on Earth.

Do you know of any others?
