- As the James Webb telescope becomes operational, we'll soon start receiving more data than ever before on the exoplanets nearest to us. The only problem is.... what ARE the exoplanets nearest to us? Today we're taking a look at our closest neighbors to see what our chances of finding alien life are close to home.

Jupiter's orbit is 12 years. We weren't watching ANY of the stars for 12 year Transits. So the small amount of recorded gas giants comes from lack of observation, not empirical evidence.
I know, right? It annoys me how so many people reporting on exoplanet discoveries ignore the obvious sample bias in the data.
or maybe they arent real?
Yes there's a good chance most planets even in the systems where planets have been detected have been undetected thus far. However what is also apparent is that super earths are very common and yet totally absent from our own solar system.

I can't imagine how much time and effort it takes to make the footage showing these planets, they all look amazing and really get the imagination going. I can't wait to see what James Webb is going to teach us!
Top quality video as always, any upload from you makes the day better, but a space video from you makes my whole week
They take FOREVER to make. Sending the probes to these systems takes an average twelve years, and then another twelve years for their footage to be sent back to me 😅
You don't even WANT to know who I had to trade with to get footage of Phobetor (2300 lightyears is a little to far for my probes, even with telescopic enhancements)
Space Engine is a great piece of software, I really recommend taking a look at it. The slightly older versions of it are completely free!
@@hex_1733 I highly doubt my poor old computer would be able to handle even the older versions but thank you for telling me the name of the software! I'll remember it for when I upgrade my rig in the future
@@AtlasPro1 watch and learn people, its this kind of dedication to your craft and planning ahead that makes you top of educational youtube.
Also, surely your mysterious trade partners must've supplied you with some alien lifeforms already? I bet they're the ones that keep changing the books in the background, they're sneaky like that
@@RyuuNoSenshi I used to run it with no issues back in 2015 on a $500 laptop bought in 2014, so it might work.
Yes please astrobiogeology. As long as we're throwing prefixes around, I'd like to see some speculation about how astrobiogeochemical cycles would be different from our cycles here on earth.
I recommend the exoplanets channel for this kind of stuff
Our understanding of solar systems is being completely redone these last decades. The common and purely theoric assumption was that most planets of other galaxies were gas giants, and that because of the comparative rarity of our star type, most systems were not only inhabitable but not even interesting. Yet, we now know how frequent solid, terrain planets are, and just how frequent water is on a galactic level (of course, in different states). Not only that, but dim, little stars can also have interesting solar systems and interact with them in novel and surprising ways (allowing for better temperature at short distances than big stars). I fully agree that the universe is really rich, and the probability of alien (animal) species is exceedingly high!

Please try Prophet of Zod and Sir Sic, 2 Extremes of the Main-Flavors.
yes
I don't think researchers were at any point suggesting that the lensing/wobbling/dimming methods for detecting exoplanets that were the only ones available to them even 10 years ago were fully free from bias. I remember documentaries from the mid-late 00s expressing the full awareness of the large-mass bias inherent to those methods and researchers explaining how that made it frustrating despite being in the middle of the first huge boom in exoplanet discoveries. The field has always been quite open about not having enough information to reliably say anything about the true distribution of planet and parent star characteristics in our little part of the galaxy. The field has also been very clear for at least 20-25 years that our Sun is actually a very run-of-the-mill, boring star, not particularly rare at all.
As much as I agree with your closing sentence and the sentiment of optimism behind it, I think your characterisation of the state of research prior is a bit unfair
Heck, I was hearing the gas giant commonality bit until fairly recently.
it's beyond exceedingly high, it's incomprehensibly likely. I would even say absolutely quaranteed. our expectations for what life needs are so high because we assume life will be exactly like us, forgetting our own planet had species that would die from being exposed to oxygen in the past (and even today!) that developed in a world completely different to what we now know. if we manage to send these little devils that live in rocks using chemosynthesis without any sunlight to even a remotely similar planet to earth, of which we in just this video have many good candidates, these micro organisms would thrive there and quickly spread everywhere and diversify into whatever. all they need is elements we know are going to occur everywhere.
that is to say, some of those potential host planets, possibly even most of them, have likely developed microbial life by accident already. all you really need is some completely normal elements in temperatures that aren't burning or freezing for enough time and sufficient protection from the sun, which even on those red dwarves with pulsating suns could harbor underground or under the ice, in a nicely isolated and absolutely stable environment.
complex life? yeah that's probably (whatever high number) of times more limited and even simple life needs some preconditions, our moon for example cannot foster that, as far as we know anyway. because it's geographically completely dead.
let's recap:
-between +100 and like -3 and stable. - temperatures don to a certain temperature might work too as we clearly see on our own earth and if a planet has a -magnetosphere it also produces some heat, so underground=warmer
-magnetosphere (needs enough mass) (correlates with atmosphere so I won't mention that)
-not gas giant
-needs enough variety in elements (maybe guaranteed, I honestly don't know)
-not around a super sun that's going to explode in a few million years, obviously
and yeah that's about it. you have a shitton of potential candidates. all of this is just down to exactly how likely is a DNA-like structure to come about and with potential help from us that problem's solved immediately. if we can get there we will bring bacteria along whether we like it or not
I used to come to this channel for the science but I stayed for the occasional glimpse of his cat. Show us the cat 🐈 more often, please.
8:54 The use of the emblems of the elements from Avatar The last Airbender are those little things that make me like this channel even more!
thats what I thought
Yasss I was looking for this comment
"Astro...bio...geography" is why I first subscribed to this channel. Please make more!!!
yes much more!
Not to mention how even if these earth-like potentially-habitable planets haven't developed any life, there's still the part where it might be able to support human life with minimal adaptation (be that biological or technological, like space suits and all that fancy stuff we use for space as we know it) needed.
I think we’ve long since past the Great Filter but the event is so improbably rare that Earth is possible the first planet to do so. That event is when a hunter bacteria didn’t eat another bacteria and that bacteria became the mitochondria. I think that event is so rare that we are possibly the first planet in the galaxy or universe to even do it.
If we develop the technology and capability to go to another solar system, I expect we will have the capability to modify our bodies to be able to survive no matter the circumstances upon arrival
8:50 I do be lovin that Avatar Referance!
'Wolf 359' .....Huh, that star is real and not something invented for Star Trek. Neat.
It’s always a good day when you wake up to Atlas Pro
Crazy to think that even if we would ever figure out how to travel at almost lightspeed it would still take over 4 years to travel to the closest planet with potential life
almost lightspeed=time dilation
It would take longer than four years at the speed of light unless you intend on heading straight past it
@@nhatminhtranngoc8940 yep, 8 years (probably more since they gotta speed up and slow down) round trip for us, maybe few minutes for the crew
Nonsense. Of course traveling at light speed the conventional way is impossible, so we have to find a way to cheat. Warping space or finding wormholes, for example. In that case there is no reason to limit ourselves to 1 x the speed of light.
In other words, 8 years at half the speed of light, and 16 years at a quarter of the speed of light, and 32 years at one-eighth the speed of light. Is that right?
Atlas Pro basically pointing out the closest habitable worlds for our Stellaris game. Great video as always! love how much work goes into them.
great game
I'm glad you included moons in other star systems as possibly habitable. Personally, in the search ET, I think we should explore our solar system's moons more than focusing on other star systems.
Wouldn’t that leave only mars as Jupiter and Saturn are to far away from the sun for their moons to be habitable?
@@therockingvolbeat3630 tidal forces produce heat internally warming the hypothetical ocean
@@therockingvolbeat3630 Exactly like @BOYGENIUS538_ wrote: as I understand it, Jupiter exerts tidal forces on its moons that produce heat inside the moons from being stretched and compressed. One of Jupiter's moons, Europa, is thought to possibly be habitable to life because under it's icy exterior lies an ocean that could be warmed by thermal vents (like on the bottom of our oceans) caused by the internal heat from tidal forces of Jupiter. If life could originate from thermal vents (we don't know yet) then it could have spawned on Europa and still live there, like life on Earth lives around thermal vents on the bottom of the ocean.
Caelan, thank you for an outstanding production! 🤩 For a long time I have wished someone would make a video that explored our closest exoplanets in logical order🖖. Others tend to present these planets in a very random way, which left me rather confused. Good work! I would love to learn about astrobiogeograghy so by all means do it!
Great video. Congrats on reaching 1 million subscribers!
It's epic to imagine James Webb sending us results from the Tau Ceti system, and the entire world going crazy with the prospect of advanced alien life from findings of oxygen in one of those atmospheres!
That's where Bob Lazar claims the UFO he worked on at area S4 was from. Based on briefings he read before starting to work on the project.
The biggest misconception we have about life, is that it is strictly bound to what we already know works. The fact that all lifeforms need oxygen, isn’t a fact at all, some single celled organisms have evolved to not needing it, so whats to say their is any bounds of what is needed for life. The reason we haven’t found any signs of life, is because we are looking for earth like life, which is most likely only native to.. earth.
Yep
Unlikely to happen honestly but still interesting. If there's intelligent life in Tau Ceti then that makes the Fermi Paradox even more baffling...
@@TrySomeFentanyl Sure but all complex life needs it. Life is still a phenomenon of the universe bound by its laws. Life still requires energy and there are limited ways to get energy. The question is whether people are looking for any life (I.e something akin to a microbe) or if they want to find animal and planet analogues and intelligent life - which would require everything we do or at least most of it. Life doesn't just spring up its a continuous uninterrupted process spanning billions of years. There's no higher power controlling it and there's nothing intrinsically special about life other than it might well be exceedingly rare in the galaxy.
Good to see the four nations put to use in this video!
Man. It's amazing! We've been so used to the JWSP being delayed over and over again it's kinda sureal that it's finaly in place.
Cannot wait for the first images ones the testing and calibrations are done!
JWS*P* ? Sure. Everybody knows about the James Webb Space Prostitute!
I too can't wait
I'd love to see more astrobiogeography tbh, this study is super interesting
Only valid field of study for Alien enthusiasts.
Don't look for excuses Mr Professional Atlas, make the astrobiogeography video, I think we'd all be very excited to see it!
Ive never been this early before
yep
Me too!
Cool
I have been earlier than any of y’all. Just ask my girlfriend……😂
8:51 Long ago all the planets lived in life but everything changed when the fire planet flared.
honestly a video going into astrobiogeography and possibly, if the information required for it is available or becomes available soon, a related topic of xenobiogeography (which would probably use the estimated composition and atmosphere of a planet to guess at what compounds might be present in their biological structures) would be really interesting
I'm a fan of the audiodrama wolf 359 (definitely worth checking out!), but I never realized it was based on a real star!
Is that about the Battle of Wolf 359?
@@GmodPlusWoW maaaaaaaaybeee
(Though it’s really more of a comedic series)
Whenever Atlas Pro posts it’s gonna be a good day
The sad part of all this is the distance involve. Even if we break the speed of light barrier, and we are able to build ships that go twice the speed of light, it will still take years to go from one system to another.
Trek fans hearing Wolf 359: “We don’t talk about that place”
Fantastic video and highly useful. It does look like our solar system's planetary configuration is pretty standard, boosting the chances of finding Earth 2.0 nearby. Fingers crossed for JWST!
Our solar system is actually quite strange it's our gas giants
Huh?
It's actually the onliest we have found in this configuration.
Having Saturn and Jupiter sweep asteroids and comets away from colliding with earth all the time.
Earth's angle and wobble.
It's moon as companion.
It's relative size to earth, and also only one moon.
Hell there isn't a single super Jupiter or mega earth classed planet in our solar system.

Hahaha I love the use of the Avatar nation symbols at 8:51
I love everything you make, and I especially love the variety. I'd love another astrobiogeography video soon, but no rush!
I wonder if there is some almost universal configuration of gas to rocky mass in a solar system compared to the star. Like a super complicated formula that if you have the star's data then you can estimate how much mass for plants should be found orbiting it. That way scientists can better focus on possible systems and eliminate unlikely ones. They probably do....I just don't know about it.
Stars and planets are created by the same gas clouds. So maybe once we understand how gas clouds collapse into proto-stars better we could understand how much leftover mass there will be for a given star type and therefore using gravitational laws understand how many possible planets there could be. But maybe star systems don't allow for gas giants due to how mass is distributed in a planetary disc or vice versa.
It seems that metallicity is highly related to gas cloud colapse, so there might be the answer... but until we can detect all kind of bodies in a system reliably, we won't really know, right now all of our methods needs a good amount of interaction between a hosting star and a planet, but if the mass or volume ratio is too high, we wont be able to detect a lot of them...
Possibly but you have to account for the age and everything that happens in between their formation and their current state as we observe them. Some systems might have the majority of early planets ejected into interstellar space.
Hey Atlas! I love ur videos and I know I'm going to love this video, keep it up! 💕
His name is Caelyn (I believe), not Atlas. I wouldn't be point this out but he did in a previous episode.
@@TheSpiritombsableye also seems to be an ATLA fan, but who isn’t?

27:45 I would absolutely LOVE to see an 'AstroBioGeography' video!
Yes, please make the Astrobiogeography video! That sounds awesome!
Incredible visuals and great detail!
Congratulations on hitting a million, well deserved
🎉
I remember subscribing to this guy at 10,000 subs and thinking "his videos are so good, why does he have so few subscribers?"
Really great video! I love this type of content. Perhaps a video on the relative position of these star systems to each other? (So that the routes that humans might be able to explore those systems can be shown)
This Video made me really excited for the future of Astrobiology! Or had you put it Astrobiogeography!
I can't wait for the stuff the James Webb telescope will teach! And What more Quite interesting and Amazing Video you will make! Might I add, How much the Editing has improved since I was subscribed to this channel(Since the Antarctica Video came out)? Really nice work dude! Can't wait for the next one!
Thank you so much for this! I really love how much effort and care is placed into all of these videos. I'm really happy I'm subscribed!
Might I offer this information that might be of interest to you:
1) Red dwarf stars are very common, but that's also because they have the longest life span, with the heaviest dwarf stars lasting 10s of millions of years, and the lightest living for more than a trillion years, compared to our sun's projected/suspected 10 billion year life cycle.
2) If memory serves correct, the most common way of detecting exoplanets is done using the transit method. If this is the case, the terrestrial planets orbiting closer to the star have a greater chance of being detected simply because they would transit in front of the star more often than gas giants that orbit further out. Like in our solar system, for example: Earth takes 1 year to orbit once, but Jupiter takes 12 years. You'd have to wait at least 24-36 years, observing our solar system from afar, to determine if Jupiter really was a planet, if that makes any sense.
I hope you found this interesting, and I hope you have a great week!
With this video and the Earth 2.0 one, you've talked about all the systems in my sci-fi worldbuilding project, and given me some good ideas! The real question is, when will the third part of this trilogy come out?
His moon geography video has another idea for sci-fi world building, 2 habitable and equally sized worlds orbiting eachother.
Now i would want to do the math to see if the tidally lock or whatever other effects would happen if you set their apparent sizes as the size of the moon in the sky, and absolute sizes at 1 earth mass/radius.
Bonus points if both develop intelligent life at the same time. So much world building potential to litterally watch another civ develop on your moon and get radio to talk to them long before rockets to visit/fight them.
hopefully soon
Yes! I waited so long for you to upload a second video about exoplanets and here we are I am so happy, the video is really amazing and well made :)
Absolutely we want another astro video! I can say your videos on space are BY FAR my favourite type of content on this channel, bring it on, the more the better :)

I really thought space was pretty boring before I found your channel... Boy was I wrong
Grats on 1M subs!
Great job man. Wonderful.
Amazing video as always
Love what this channels grown into
Absolute fav on yt
The more we learn about outer space and the things in it, the more amazed I find myself about both outer space and life on our earth! 🤗 Can’t wait to see what we can find out with the help of the James Webb telescope! 🤞
Great video! Super cool stuff.
Your depictions of these alien worlds where really interesting and well done. The fact that we know so little about them made me very curious about everything that's in our own backyard, the objects we do know a lot about. The objects we have actual pictures of. You might've already made a video like this, but I think it'd be extremely cool if you made a video about some of the lesser known or interesting things we can find in our own solar system. Like moons of the outer planets that we've caught real pictures of and stuff like that. I found it extremely difficult to separate the rendered/edited from the authentic when looking for these types of images myself. You could also maybe talk about their compositions and future prospects if we ever get around to mining or transforming these worlds. Some other things I think would be really cool to have visualized in a video format could be the space between asteroids in the Kuiper belt or the size of Jupiter/Saturns cores. Or maybe the possibility of tidal forces on the satellite Phobos? That'd be kinda interesting if there's any grounds to that idea.
Just to clarify what I meant by tidal forces on Phobos: I believe it's been the common consensus for a long time that the grooves along Phobos exterior was caused due to an asteroid impact, but I vaguely remember reading somewhere that someone challenged this notion by suggesting that they're actually caused by tidal forces acting upon loose rocks and dust upon its surface. I don't know if this is a plausible theory tho, since Phobos is relatively quite small.
I'm pretty sure his depictions are a game called Space Engine.
LOVE the new vid bro! that older video was one of my fav's. Defo upvoting more vids like this. =P
Creeping closer and closer to Speculative Evolution every day

As a student of environmental science, active in a youth astrobiology club I LOVE your videos! This one was amazing! Keep up the good work
I've been watching your videos for a while, but the video that made your channel stand out in my mind was the first Areology video. I'd love an astrobiogeography video (or several)!
9:15 poor one out for my homies. Resistance was futile for them :-(
I would love a video on potentially habitable moons such as Europa, Ganymede and Enceladus.
I believe to this day that underneath the frozen ice of Enceladus there's all sorts of alien creatures swimming in the oceans
Please make more of these!
Always waiting for your new videos
I flown around most of these systems. Travelling to all the stars of the Southern Cross was a bit of fun. There's over 70 light years difference between the four of them, as measured from Earth.
But most systems are pretty boring. Trust me on this. And jumping between stars gets old, really quickly: the view never really changes. And the stars keep going on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on, and on.
Fuel scooping at the odd star doesn't alleviate the boredom, even when your ship's temperature means there are alarms going off all over the pace.
great storytelling
Yes please make an astro biogeography video and also I imagine humans could go to at some point in the future Barnard's star and evolved to fill the ecological niches there an adaptive radiation from plant to animal to fungus-like forms
Fantastic work, can't wait to see what comes next
I love your videos! So awesome! Thank you!
Me: im gonna do something productive now
Atlas pro: uploaded video 1 minute ago
Me: .... i have time
Great content and video production!
I hope we find signs of life during my lifetime, but I'm very cynical about it. If we consider earth to be idyllic to the formation of life (indeed, it's the only environment we know of to have produced life), when we consider that life evolved on earth once and only once, I'm doubtful we'll find life anywhere else. Time will tell, perhaps, but I fear it's much, much more than just a few years away.
I really enjoy this, Thanks! 👍
I love your Astro Bio Geography videos. Sometimes I watch them twice ;) . Got to say I was so hoping you will reference Babylon 5 when you mentioned the Epsilon Eridani system.
astrobiogeography sounds interesting... although with our present knowledge such a video would consist with almost pure speculations. great video as always! don't let us wait too long for another one ;P
My favourite planets: Chip and Dale
You gotta do a Speculative Evolution project for Chip and Dale now. It is your duty.
This was awesome, keep it up man.
An astrobiogeography video would be a really exciting video to watch! It’d be interesting to see what you do and if you delve into speculative evolution.
Congrats on hitting a million subscribers, keep up the good work!
Great video! Keep these coming!
Thank you for making these videos,, i really like them they are so interesting and also presented in entertaining fun way i love it every video is quality best wow
BRUH im early (lets goo) love your vids btw one of the best channels for this style of content
last night, me and my friends talked about panspermia and its possible role in seeding life here on Earth from other planets, but with the idea of astrobiogeography, i'm starting to wonder how isolation-related evolution would look like in an interplanetary scale. like, what could have been the differences between life here on Earth and possible life on Mars or Venus back then? based on what we understand in terms of the factors related to the formation and evolution of life, could we figure out what life could have looked like if they started out in early Mars or early Venus? and considering that Mars had different conditions than Earth, what would be the differences between the life that evolved in each planet?
for short...yes, please. we want astrobiogeography.
interesting
You should check out spec-evo! Some types of spec evo projects deal with how alien biospheres could develop given planetary conditions. Some are completely alien, and some are premised on "what if we dropped animals we know into this enviroment, what might they be like in millions in of years?"
I really dig your "Optimist Hat" phrase; I'm going to start using it myself if you have no objections...hey - maybe I can wear it along with "Upbeat Sunblock" nxt time I'm on an island/planet holiday? ;~]
Great work, dude! Lord knows how you mnge so much research but it shows; good on you!
really love this channel, gratz on 1m
I love all your videos, but the space themed ones in particular, any more astrobiogeograhy would be amazing :D
Really Great video, thank you!
I have always wandered what are the limits planet-mass-wise to the habitability. Frankly speaking one can always get exceptions when talking about temperature and athosphere density. But apart of that how do you think low an especially high gravity would influence the potential life forms on such planets? Will snake-like forms evolve?
new atlas pro video man today is gonna be so good
I recommend the exoplanets channel for this kind of stuff
An astrobiogeography video would be bloody cool!
10:46 there is it’s 10,000 to 1 ratio for a earth size moon the gas giant would have to be 10,000x the mass of the moon so it would be 31.5x the size of Jupiter which would make it a brown dwarf size planet, but it’s unclear if a brown dwarf could host a moon of the size for life .
He meant the moon count, not the moon size
These types of your videos are your absolute best. Please make an Astrobiogeography video!
So excited for JWST
CONGRATS ON THE MILLION SUBS! Much deserved brother it’s been a pleasure seeing the upgrade in video quality over the past 2 years i’ve been watching you, here’s to more success and even better, more knowledge to feed our hungry brains! we appreciate you💙💙
