It's truly sad seeing so much money going to war instead of meaningful advances in sciences that will take us to the next level.
so much. hidden..
Super-earths orbiting further out than the traditional habitable zone have a VERY high chance of being ocean worlds, with a large and hot core able to drive undersea volcanoes for billions of years. If they orbit a red dwarf, and the orbit is just slightly eccentric or it has other planets in resonance with it, the core will never cool down due to the tidal interactions.
Imagine if being and alive meant the same thing for you. Then all that exist would be alive, moving, reproducing. It would be river of undifferentiated life.
Luckily the mind says "no" and we believe him 😅
‘Life’ is the counter argument.
Our chance of sending humans to even the closest of these exoplanets is so low it approaches nill. The money, effort, tech, study...and most if all time that it would take to even FIND OUT if theres life or are habitable for humans....to me, it doesn't seem like Iike this will ever happen because we won't make it to that stage.
Not to mention, physics itself and the svales of distance involved is not on our side. It would take generation ships and hundreds of years to go to even the closest stars.
We are talking distances of LIGHT YEARS people!!!
The problem with red dwarfs is that they are highly active with constant flare ups that would disintegrate any atmosphere of any planet within a certain distance. Most of the planets would also likely be tidally locked which could cause other instability problems.
@@dbsti3006 Agreed. This planet would also need to possess a spinning metal core to deflect it's star's constant radioactive death rays before it could begin to harbor life as we understand it.
The cool thing about this idea is that it gets rid of the primary concern about red dwarfs: that the star is too violent for life to survive the radiation. Ocean life beneath a sheet of ice would be well protected from any potential super flares from its star.
Some of the stars are the most inactive found as well. Like lyten star or LHS 1140 although the planet orbiting it is likely a mini Neptune
Also are sun produces these flares all the time
I hope I live long enough to hear about life being discovered on another planet or moon.
Eat more fruit, do more exercise.
@@ivarbrouwer197 Well, let's not get too radical.
@@philochristos oh yeah, if it’s about radical measures, also, get a girlfriend, brush your teeth and all that.
A book by David Brin (A really good SF author.), examining cultures of beings in an encapsulated "water world" and their reaction to the appearance of strange beings from outside their known universe would be a fantastic read!
It kind of amuses me that some advocate for life to occur nearly everywhere, while others insist we are alone. We simply do not know! There is absolutely no sense in arguing until we have more information!
Thanks, Anton.
We all begin with the premise that we don't know. But speculation is entertaining, and leads to a hypothesis. A hypothesis leads to experiments and increases our understanding. So yes, arguing serves a purpose. We know that life has occurred on our planet. We know that the materials needed to sustain life, as we know it, are abundant throughout the universe. We know that there are billions of stars in our observable universe. We now know that planets among those billions of stars must be common place. I submit that it is not only possible, but probable, that there is life elsewhere. Arguing (debating) will bring us closer to knowledge.
@@billskelley6895 Ye, I'd like to add to that statement the following: Life finds a way. "Observable Universe" is soon to be accompanied with "Biological Universe". Instead of a perfect circle for the observable universe, the boundaries of the biological universe is probably just blobs and patches based on various markers like Liquid water / cryo volcanoes / atmospheric readings, and perhaps direct biomarkers or (if fate allows it) technomarkers. The ingredients for life aren't **perfectly** evened out, that's the problem.
Panspermia is a theory, for now, but if proven true will result in HUUUUGE numbers of planets with life. Even if that life is dead or hibernating until better conditions.
@@billskelley6895 IDK- do we really know all the various forms that life can take in the universe or do we only know of life as we know it? Kind of important question. Because when looking for signs life, and all the rest, we're basing it on our ideas of life, which are firmly based on life as we know it from earth. We have no idea if there can be other kinds of life until we encounter it. So, rather reasonably, we seem to be looking for signs of life we will recognize, but we should always be aware there may be signs we don't recognize as such.
I most certainly agree that life is probable. I'd also point out we've barely started looking. And while we may think our technology advanced, it is in its infancy. So any conclusions at this point about life, similar or not to earth, existing elsewhere I think is premature. Unless of course we get a definitive positive answer. As they say; Absence of evidence is not evidence of absence. We have a long way to go before we can make any conclusions about the absence of life. We haven't even left our planet yet, much less left our solar system.
If a civilization lived trapped inside a planet, could they imagine stars and galaxies? Could they even imagine an outside?
I wonder what it would be like for the inhabitants of a super earth, several times the mass of ours. They might be able to see the stars and other planets, but because of the high gravity may never achieve escape velocity to visit them or even get a telescope above their atmosphere for a better look. Effectively trapped there for ever.
They could even have a better view then we do if they a patch of surface with smooth ice and no atmosphere
If the had detectors that could capture images from Neutrinos that civilisation would be able to see a Neutrino-based image of space. Potentially using Neutrinos it could even possibly see the origin of the universe and the moments just after the 'big bang'.
That sounds like a great plot for a sci fi novel.
If a civilization was trapped inside a universe, could they imagine what it would be like outside of their universe?
As more JWST data accumulates it's going to be very interesting to see if any plausible bio-signatures are detected associated with exoplanets. If so this could be the first direct experimental observations supporting the 'Rare Earth' hypothesis. This could represent the first real movement of the hypothesis into the realm of Theory.
Right now it's still purely speculative and we don't know what the data will show, but it is quite exciting.
For those familiar with it, the 'Rare Earth' hypothesis postulates that complex life (metazoans) are exceedingly rare, but that simple life is very common.
As usual thank you Anton for excellent presentation of topical subjects of current research!
Life doesn't have to start on a planet. Microbial life, as we know it, must have a source of H20 at least so there's nothing to say it can't happen on a moon. It doesn't even need to be in the habitable zone of a star, the gravitational stress of put upon a moon by the planet it's orbiting can generate a heat source too.
@@Goatinaboxexactly. life is way more common than people think, there’s literally multiple moons in our solar system that has liquid water and other signatures and we don’t even know if life is under there
@@Tokirumithe JWT has already been used to analyse the atmosphere of a potential
'Ocean' planet, K2-18b, about 120 light years away, where it may have detected in the atmosphere dimethyl sulphide, a chemical that we know is only produced by life here in Earth.
However, further investigations so far are not looking favourable to it being verified.
I have to wonder if the chemical signatures might be masked by isolation from the planetary surface.
@@matthewludivico1714 what do you mean by isolation from the planet's surface? Unless the chemical signatures are in the atmosphere the JWT isn't going to see it.
An Enceladus mission needs to be fast tracked. If I could go anywhere Enceladus would be my first choice.
The mind boggles over how different the development of any potential intelligence would be on a planet/moon that doesn't have stars visible in the sky, with no concept of "out there." I can't wrap my head around it.
Thank you for all you do, Anton. ❤❤
It would be hilarious if tardigrades was found in the geysers.
Tardigrades turns around and says -shite, hey guys i thought it would take longer
😂 Somehow I just wouldn't be surprised.
This could mean either all life in the universe is converging towards the tardigrades, or... the alien invasion has already begun! 👀
There are times in earth's history when if we looked at it, we would say how alien it is. Especially billions of years ago. Further back we would say it does not support life and write it off. Seems like it depends on what period a planet is when observed. What a planet hosts can be very different from one billion years to another. Also, what we are seeing today is what these planets were like very long ago since the light we see traveled over a very long time to reach us.
Well, yeah. It would be very silly for us to look for exoplanets that might host life in two billion years, or ones that might have done two billion years back…
The situation will be different over billions of years. But how fast can a planet change between these ?
🚀🏴☠️🎸
Given that the observable universe is only 46 odd billion light years, I don't think this is too relevant to the Earth-like planets we are searching for today. There are candidates beyond our solar system as close as 4 odd light years away and the Trappist-1 system is only 40 light-years from Earth.
@@MartiensBezuidenhout If considering traveling to any of those planets, 40 light years is still a very long time if you consider how long it would take to get there realistically. I doubt a vessel can carry humans at light speed. one of the probes is traveling at tremendous speeds for decades and just recently left the solar system.
Icy moons that have oceans under the ice are cool and promising! 😀
Life can exist in ice too given the right conditions.
After being subscribed to you for a few years now and watching many of your videos ive come to the conclusion that you are a god or some kind of interdimensional entity that has been around for many cycles of the multiverse and knows all the answers and make these videos to try to get people to think correctly about existence
Great Episode. Always enjoy your calm demeanor and intelligent discourse.
Thank you so much, Anton. We are grateful for you. A wonderful person indeed.
Wonderful = full of wonder
Thanks! For a few years I've enjoyed your content.
Wonderful as always Anton. Thank you. 😁👍
Your videos are so interesting! thank you.
The density of the Trappist planets has been recalculated to be only slightly less dense than Earth, meaning all except Trappist-1h are similar to Earth or Venus in terms of bulk composition. Trappist 1h is very similar to Mars, just a bit larger and colder.
That they are slightly less dense indicates either they do not contain iron-nickel cores as large as Earth's, or they have global oceans, but not as deep as was previously thought. Perhaps in the range of 10-20 miles deep rather than several hundred.
Water is much less dense than rock, so the shallower the oceans, the denser the planet.
@@damiensmith9240 Good point. Never thought of that.
If we get to Enceladus or Europa there are three main possibilities.
1)we don't find any life. This is kind of the most "bummer" possibility but it does tell us that "where there's water there's life" is incorrect.
2) We find life but it's closely related to Earthly life. This means that interplanetary panspermia is real and that life is very likely to have existed on Venus and Mars and even our own Moon in the past, but it doesn't tell us much about the potential for life in other systems.
3) "We find life and it's not related to Earthly life. This is the most exciting because it would suggest that life is common throughout the universe.
or
4) it's getting late. I've had too much to drink. I should shut off my computer, and go to bed.
If we ever find a planet with actual purple rain, can we name it 'The Planet Formerly Known As Prince'?
Cheesy dad joke.
2050? Damn... Think I am going to have to chalk that one up as something I won't get to see.
I love your videos dude🙏
Makes sense quite possibly how life started on snowball earth under frozen oceans.
Exactly what I was thinking. Life seemed to survive two snowball earths despite evolving in a warmer environment. We need to explore Europa asap
@@PlanetZeroVideosEuropa was always frozen. I doubt it ever had the nuances Earth has.
Yeah the environment would be constant for a long period of time and high radiation would be practically non existent.@@PlanetZeroVideos
Can hardly wait for more to be known about the Trappist exoplanets.
Wow i watched your shorts! Why you're in seoul now?! I'm in seoul too! Happy new year anton!
A thick layer of ice is also REALLY good radiation shielding. No need for a magnetic field and can host life around what we would consider inhospitable stars.
I would expect gamma rays and cosmic rays to penetrate kilometers of ice easily enough so it's a roll of the dice if the ice could do the job of protecting life long enough for those rays to sterailse life at some point over the eons, depending on the strength of any gamma ray bursts.
We had one reach earth from a distance of 2 billion light years only a few months ago that actually registered for 800 seconds (!!!) it was so powerful. Can you image how powerful that must've been that we could physically see it's effects on our atmoshpere for such a long length of time.
It needs some radiation to keep evolutionary mutation rates.
@@MichaelWinter-ss6lx that too.
This is really exciting. Discovering life on one of these worlds should be given the highest priority.
This planet went through it's own 'Snowball Earth' phase in the past. Is it possible some of these planets are at the same stage and just awaiting an event similar to what ended the snowball Earth period?
What research is there into alternative propulsion methods to rocket power, for launching small unmanned vehicles outside Earth gravity (exceeding 11 km/sec) ? Anything like a centrifugal slingshot for launching a cubesat(s) or lightsail(s) which might then be further accelerated by a laser beam ?
One of the methods they have for eventually getting through the deeply thick ice layer is a nuclear powered heat rod, which would slowly melt in a straight line. Carrying with it an extremely long connecting cable to a submarine. There is not many other ways.
A laser
@Goatinabox,
That laser would still need nuclear power. That far out there's no other option. So there is heat. What advantage could a laser then have ?
🚀🏴☠️🎸
@@MichaelWinter-ss6lx A pulse laser from orbit, little atmospheric abberation. But then you need to keep in mind the ice sheets move, probably in layers, so gotta go down fast.
Also that means sisues for any cable.
A nuclear heat rod? Just send a giant robot with huge auger.
@@MichaelWinter-ss6lx I'm not saying don't use nuclear power, I'm just putting forward using a laser rather than a rod.
There is a real possibility of highly advanced beings under thousands of feet of ice and have never saw the sky and have no idea whats out there. Makes you wonder.
Life only exist in one place at a time in this vast ocean of universe. We are alone! Well this is just a blink of an eye after all, a dream.
I recommend we mine the heck out of out moon and build space craft, fuel and go visit :P
Need to go to Enceladus now!
There are so many questions that need to be answered to make any speculation like this worthwhile, in my opinion. Are there multiple pathways to life, or must it start like it did here? Can it only evolve with RNA to DNA? How many of our planet's variables were necessary? (Did we need a moon and plate tectonics, did we need what seems to be the unusual arrangement of smaller planets in the inner system?) There is just so much we don't know. We gotta start being able to analyze the atmosphere of exoplanets en-masse; it seems like that's the only thing that will ever have a hope of actually finding life. And if we ever find life in our system, that will at least add some value to the speculative questions.
Thankyou
I hope alien life is discovered in my lifetime
I'm pretty sure it will, but don't hold your breath for something similar to us.
@@NoidoDev After reading Three Body Problem and other sci-fi, as long as they're not intelligent life, any form of life micro to macro is more than great for me.
Mars is both colder and less dense than Earth and yet is bone-dry (mostly), so this study should find out which exoplanets are more Europa-like and which ones are more Mars-like. And more importantly, WHY some are one rather than the other.
Hello wonderful Anton
Hi Anton I ask if you record something about Kepler 132 you do great jobs
Its all about 🎶"Ice Life...Maybe!" 🎶 😏🤣🤣
So with a thin or fractured crust so new materials can get in?
Closer they get to their host star maybe even meaningful amounts of light can get through..?
I think earth used to look like an ice ball, in the past. It's called snowball earth theory
It's not a theory, it's a hypothesis.
I’ll bet there are more than 17 known exoplanets most likely to ROAST life.
It seems like it will be really hard to confirm the existence of life on such worlds. It would require spacecraft to land on the surface and drill down into the warm zone, and then be lucky enough to hit the right area and actually be able to analyze what's down there.
Since you mentioned the planets density, I am sparked into thinking that our density is a bit higher than other planets found so far , that are relevant to our planet.
Since I can't seem to upvote any video on CZcams anymore, here's an upvote.
Also don't forget ammonia habitable zone with Trappist one g and h with g having the greatest chance of air due to shere size. Probably a hycican world.
Kelper 186f is in the inner edge of it along with kelper 296f.
Supposing that alien life is common, and we are not so special. This may be the case, get used to it!
Would tidal heating affect lifeforms directly in similar ways to standing in front of a microwave antenna?
I would like to know more about the effects of radiation and the powerful magnetosphere through which Saturn's moons must pass. Exoplanets without these factors or possibly far greater radiation levels will differ enormously from the ice moons of Saturn in terms of jeopardising the survival of life. What do we know about the shield provided by water or methane ices? A form of life that can survive constant gamma radiation exposure, is that even possible. I think that the assumptions made here about similarities between exoplanets and the moons of our solar system are rather broad.
You’re probably the smartest wonderful person on CZcams..
In the book 2001: A Space Odyssey, The great Prophet Arthur C. Clarke, prophesized that life exists on Europa, another icy moon. This was back in 1968.
Still not a reason to not go there…
I'm sure NASA has very valid reasons for waiting so long to visit Enceladus, but it just feels, given what we are learning, that it should become more of a priority than putting men back on the moon.
Men and women (whatever that actually means these days)
@@PetraKann
LMAO 🤣🤣🤣
The technology isn’t quite there yet, but it is being worked on. (Though, if it got enough money it would be possible.) But still, proper examination of actual extraterrestrial life, as well as the multiple mile long path that would be drilled to get under the ice would be difficult. Imo though I’d love if more money were dumped into this type of stuff it should still be taken slowly.
That "really good reason" NASA has is Money.
Public Money.
That must come through Politicians.
No, the moon has more diverse opportunities to offer. Life on Enceladus does not mean money or industry
I wait for view of exoplanets around Proxima centauri.
They've got a solid atmosphere.
So cool... Give me Hoth or give me death! Uhh... actually that adds up, I stand by it. 😉
Thank you, Anton! I appreciate you sharing fascinating aspects of our universe. Could comets transport life to where they land?
Very interesting - what do aliens find trivial in us?
I have, and I've already gotten answers @@Jay-cf6dz
Depends if our porn turns them on
any ice fishing expeditions planned yet?
I am always amazed that from a pixel we can know the full appearance of the planet.🎉😂. Let's assembly a modular telescope! So we can just send parts for more magnification!😊
I have no doubt that any water world orbiting its host star in the habitibal zone would also harbor life !
I can’t wait ‘till ‘Roman’ is turned to Alpha Centuri A & B, then Both the Zeta Reticuli ‘G’ stars. Until then, you can hold the exoplanet news
Kepler 22b
That's the big question...how did life begin on our planet... The amino acid theories have been debunked...which makes sense because you need a biological catalyst for that to happen, so where did it come from if it couldn't be generated by earth's elements and their interractions... It leaves the theory that the catalysts came to earth in an asteroid from some place else in the universe...which further supports that earth is not the only planet to have hosted life... Very interesting and controversial subject that we may never ascertain the answer to...
Its a shame they didn't built 2 JWSTs.
True, but there are other telescope being built along with a dedicated space telescope for looking at habitable planets
We'll get to Enceladus before the 2050s!
If we gain some wisdom before then, and get our act together!
if a planet doesn't transit across its star then we can't tell what it's made of. that's really limiting. to consider going to another solar system, sending a robot ship, we would have to think in terms of decades of monitoring a planet before deciding it was worth visiting. i really don't see it happening any time soon, hundreds of years soon.
I am wondering how much an ocean protects life from devastating radiation coming from the sun or nearby supernovae? And would ice on top of the water further in increase the protection from radiation?
You should see the 2013 movie about this topic Europa Report
In an infinate universe, I would consider rarity as a relative concept.
We have to start thinking about a gravity range for possible life and evolution possibilities. And psychopathy data within alien species. and other variations of insanity arising in all species over time.
The first possibly erroneous assumption is that life needs water. Sure, the life we know about needs water, but that's a very earth-centric way of thinking about life in the universe. Life needs complex chemicals capable of interacting in a coordinated way to sustain and replicate. We don't know for sure that means water is essential. What's more likely to be essential is carbon, because that seems to be the element that is able to make the greatest variety of large and complex molecules and polymers that are capable of being organised in a way to facilitate biochemical processes.
Can't wait until we get Invasion of the Giant Strawberry Slushpuppies in the cinema.
@Anton Why do you think these primordial soups need to be served that hot? Wouldn't vulcanism beyond IO burn any chances of life?
In terms of speculation, how much does an Ice Surface Structure mitigate dangerous (disruptive) Radiation from stars and other energetic objects? That's where I would place our bets... on those that had any of those features + a strong Magnetosphere to help ward off the Cosmic Radiation that could disrupt DNA stability.
We have to include what we know about local biology as best we can when planning these VERY expensive scientific missions or projects. Humanity and it's Social Systems aren't quite ready for "pie in the sky" proposals, because our current systems are SO VERY WASTEFUL.
Need to find a tropical planet with beaches and warm weather. Not a fan of the cold!
One potential difference with Europa compared to the exoplanets that were mentioned is that Europa is bathed in a great deal of ionizing radiation from Jupiter. This radiation has been hypothesized to create a redox gradient in the ice shell of Europa that could result in a significant amount of oxygen constantly permeating down to the ocean beneath the ice. This oxygen could then have assisted in the evolution of collagen proteins which are necessary for the evolution of multicellular life.
Otherwise, the only alternate significant source of oxygen might be from cyanobacteria that is tuned for infrared light that might be emitted from volcanoes and thermal vents at the bottom of an ocean, and on Earth at least most cyanobacteria work with visible light frequencies.
However, the red dwarfs that these exoplanets orbit typically emit a lot more radiation from flares than our Sun emits, and with the closer orbits of their exoplanets could this radiation be an adequate substitute for the radiation that bathes Europa from Jupiter? Without a redox gradient similar to that which might be occurring on Europa, these exoplanets might only have bacterial life and no multicellular life.
Also, with Europa's small size, the pressure at the bottom of its ocean is not thought to be very much greater than the pressures at the bottoms of the deepest oceans of the Earth. This might make it possible for infrared cyanobacteria to exist close to the bottom of Europa's ocean where the volcanoes and thermal vents might be. However, with the greater size of the exoplanets, might the more extreme pressures at the bottom of their oceans place their volcanoes and vents beyond the reach of even the most pressure-resistant infrared cyanobacteria?
A very interesting and thought-provoking video. Thank you.
If _life_ *can* find a way, then _life_ *will* find a way.
🚀🏴☠️🎸
@@MichaelWinter-ss6lx I'd be very surprised if none of these worlds have life. The big question for me is whether the life is multicellular or not.
❤❤❤❤❤
Ariel = Atmospheric remote sensing infrared exoplanet large survey from ESA
Well, the truth IS out there. I want to believe.
❤
If there is no life but water then we will have to be careful not to seed these worlds with tardigrades.
Why would that be bad?
So I wonder what a possible humanoid type of creature might look like on a planet with 5.6X the mass of the Earth.
If one thinks that a person who weighs 100 lbs here would weigh 560 lbs there, would they be smaller but insanely stronger than us?
Just wondering...
UFO at 0:44 in the upper right! Alien life confirmed!
The main thing that gets me about these many videos I see about potentially Earth-like, life-bearing exoplanets is this: Many of them orbit red dwarfs. Red dwarfs tend to mega-flare, I think partly 'cause they're literally little, embryonic stars that can expect to live at least a trillion years. Their mega-flares make our Sun's solar flares look like firecrackers. Yet I see people, including you Anton, go on and on about potential life there. I find it very hard to believe ANY life could evolve in such an environment, esp when the planets are really close to their home star like Trappist 1.
Yes, but the potential is still real if there is a thick ice layer that protects possible life inside it ,in the ocean, from the red dwarf's flares and radiation.
I agree! And in addition to the large flares, the planets in red dwarf systems, in the liquid water zone, are very likely tidally locked-one side always faces the star.
@@todrichards1105 Wouldn't a tidal lock create a larger chance of life by having more environmental variation on that planet (or moon)?
Red dwarfs also calm down over time::life might get more chance a good few billion years later.
Your post seems to completely ignore the fact that we're talking about life existing under potentially miles of ice. Where it would be quite well shielded.
👍
How depressing-I’m very unlikely to be alive in 20 years. I wish they’d hurry up
How is the density of exoplanets derived?
By finding 2 more basic properties first.
The Volume.
And the Mass.
The Volume is the easier part for a transiting planet. The planet's diameter is related to the rise and fall time of the light curve. These "shoulders" are the time it takes for the planets disk (diameter) to go from just touching the star's disk, to being fully within it.
And mirrored as it exits transit.
This "shoulder time" will be a small, but measurable fraction of the planet's total orbit (time between transits).
Get an estimate of the star's mass and you can apply Kepler's laws to get the size of the orbit.
Getting the mass for a transiting planet is the harder part.
The opposite is true for a planet discovered by radial velocity. The mass is easy, getting a diameter is hard.
The best case would be a planet where we have BOTH transit and radial velocity data.
But these would be mostly hot Jupiter types.
For these light weight Terrestrials in a multi-planet system like Trappist, the best bet would be to carefully record the transit times and analyze for gravitational perturbations between the planets.
i get annoyed by the fact people say this could be possible- then do very little to find-out
Just one exomoon… so many exoplanets.. . We just want to see exomoon confirmation data. 🤓💚♾️
if Kepler-438b has a good magnetic field, that could be a half-decent exoplanet for life
Highly unlikely seeing as it's about the size of a moon and may be tidally locked. The Twilight Zone may have a chance to support life but it's star is a Red Dwarf and is therefore unstable and bombards it with solar flares with a periodicity that would most likely sterailse the planet each and every time.
Aren't the Trappist planets tidaly locked with their star? How are tidal forces supposed to do much there? It's a mini planetsystem, but the distances are still much more than as with moons around a planet.
🚀🏴☠️🎸
The earth may have been an ice world one time in its history.
It's going to be so exciting when we find another planet with liquid water on the surface, there has to be life out there in some form.
It's impossible for life to exist elsewhere.
