- 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.

Normal people: Is Australia a continent or an island?
A. Pro: Australia is a Geographic Realm and Planets are Islands!
both
Atlas Pro > Astro Pro > Atlas Pro
So Astro Pro is both better and worse than Atlas Pro. How, though?
@@CasualMitosisCollective
Yes
Ouroborgator or however you spell it

Atlas bro
The red dwarf being more common is a dual factor, of which you only mentioned one. A smaller star requires less gas to form, i.e. more can be formed from the same material available aka more are created. They also burn dimmer but for longer than the larger stars do, therefore the ones formed stick around for longer. So more are formed, and the ones that are formed stick around for longer, giving us two reasons to see more of them
Love the term Astrobiogeography! It just now needs its own Wikipedia page and journal.
Go ahead and start it!
Or Bioastronomy?
@@corrinflakes9659 if plants are alive and we find green planets plants have cells cells are alive aliens?
@@corrinflakes9659 or do we specifically have to find animals for it to count
@@mtgoat179 Why are you asking me? I’m not an astronomer, physicist, etc. I literally go to school for art, space is just pretty.
Unless you want a public opinion, then I think plants definitely count as life. Thing is for reference of our own history, animals evolved shortly after plants but only after fungi already did, as we are more closely related to a hallucinagenic mushroom that’ll give you a good time than the hemp that provides the cannabis.
If a planet is more resembling to fungus, that counts too. But regardless, plants indicate life more as animals move around all the time, a plant is reliably stationery.
Astrobiogeography?? You madman. I'm with it.
I'm so glad you made a channel like this! You are one of my favorite geography content creators, and now you've crossed over into my other favorite topic of astronomy! Please keep up the amazing content. I can't get enough!!
i almost thought i was on atlas when he played that intro
finally another person who likes both geography and astronomy
Commenting to increase audience engagement/ algorithm recommendation junk.
One of my favorite creators!
Love the not-so-subtle reference to Avatar: The Last Airbender!
This always has been one of my favorite videos on the main channel. Really looking forward to more such great videos on both space and geography.
What is the main channel?
@@argh523 Atlas Pro. There's a duplicate of this video too.
I assume this channel is supposed to be astronomy specific.
What the heck? I just binge-watch your whole channel just last night and this channel just showed up this morning (in my time zone) with videos from 12 hours ago? Immediate Subscribe.
Very nice space engine in background
Loved this style of your content especially so happy there's a dedicated channel for it now!
This Channel is a WELCOMED addition to TH-cam. great stuff, keep it coming
I’m really excited for this bew channel man, good luck and keep on producing phenomenal content
Came here to see if people noticed the ATLA reference. Was not disappointed!
Look forward to seeing alien planet close up pictures.
8:43 Water. Earth Fire. Air. Long ago, the four nations lived in harmony, but everything changed when the Fire Nation attacked.
Can't wait to see more of this, man!
7:43 "...and while technically we haven't found any exo-MOONS yet..."
Kepler 1625-b-I and Kepler 1708-b-I: are we a joke to you?
I'm loving all your videos so far!
Love the Chanel! Its great to have someone finally covering the topics you do! One thing that I always think about when I hear about new planets being discovered is wanting to go and explore them somehow someway, but when you realize that the mass of the planet, also equates to the gravitational force on the planet (1 earth mass = 1 G of force) so if a planet has 4x the mass of earth, it is going to have 4 G of force on it, an average 200 lb man on earth is going to weigh 800 lbs on the new planet, so it's not like you would be able to pick yourself off the ground let alone walk around on this new planet. I am going to watch your video on habitable exoplanets next, hoping you have this in the equation in that video
Your two channels are my favorite between all those im subscribed to. Your videos are a treat! And I'd absolutely love an astrobiography video
Everyone asks “what da dog doin” but no one is asking “how da dog doin”
Fantastic you made this channel! Can't wait for new videos.
I love astronomy this video is amazing
Discovered your channel! Great job keep up the great work!
i love the space videos, keep em coming!!
I love all of your information and dedication.. Do you want todo any videos on ancient archeology.. Like Puma Punku? Your attention to detail and focus on it makes me explore it vicariously through you.. Thanks for all your hard work! Did i mention im a big fan?
I didn't remember watching this a few months ago, but I liked it over there so I assume that I did. I had always thought of the astro side as a continuation of geography and biology, but you do you, bro
Your channel is criminally underrated
Didn't know you had another channel! Awesome!
A lot of people never noticed that in Avatar, Pandora is actually a moon of Próxima C
A moon of Polyphemus which is a gas giant orbiting Alpha Centauri A, not proxima
Great video... Thanks!
Love this channel
I’m a gas giant after eating spicy Mexican food!! 😅😅 awesome videos. Hope to see more. I’m burning through them 😊
Awesome video. it'll be awesome to see probes going out to other solar systems some day or science exploration ships.
Great video 👍
Actually, the JWST wasn't primarily designed to sus out exoplanet details. It can do some of the work, but only if that work can be done in the infrared spectrum. TWINKLE, PLATO, ARIEL, and hopefully in the future, HabEx, are specifically designed to characterize exoplanet atmospheric composition and other relevant parameters to quantify habitability.
Great video and good work. Like you stated, many of these systems likely harbor smaller worlds and moons that we simply cannot yet see due to our technological limitations. Even Alpha Centauri A and B almost certainly have one world according to the data. It has simply proven a difficult system to investigate.
I remember hyping the Alpha Centauri system when they mooted it in the mid 2010s and... getting burned, when they retracted their findings. (Our host might have flashed a screencap or two about the hype, but I'm actually glad he didn't, because I might have started weeping. What an embarrassment that was.)
Proxima's system by contrast has held up.
not enough videos, they are addicting
Super video!!! Saludos de España... :)
Love this one, really inspiring!
This is excellent channel with a phenomenal host
Yes, please do an astro bio geography video.
I love how exoplanet studies are cross pollinating science disciplines! 🌎 🌟 💫 ☀️
There are barely any comments on here. I feel like I got here early but I’m here 2 days after it posted
I’m dying to know what happens next on Chip & Dale. More Astrobiogeography please!
Request to make a playlist with all your videos. I like to watch your content in a series.
8:54 I see you are a Avatar: The Last Airbender Fan. I am in good company. 👊🏾
I love your exoplanet videos, you actually answer a lot of questions that I have. I wonder if you could answer this question, why doesn’t io Jupiter’s volcanic moon, have a substantial atmosphere?
Jupiter's gravity is strong enough to take most of the gas for itself.
At 2:00 i said out loud "i like that idea" !.. cool video awesome info. #YOLO
i love that ur using space engine!
this guy deserves so much more than 10 mil subs...
ATLA reference 😅
Like for the disclaimer at the beginning.
Most Media Outlets forget these.
First video of yours I’ve stumbled across and loving the content so far! A question I wonder about the potential habitability of Proxima Centauri’s planets (barring radiation death), is what effect does the primary sun being a red dwarf have on biological bodies? I’m assuming it’s giving off less heat and light in general, as well as a creepy red glow over everything.
If the distance between Proxima Centauri and A & B isn’t massive, I suppose the other stars could supplant the necessary light requirements?
the avatar movies are set on a moon around a gas giant in the centauri system, which is quite interesting
Aegir? Missed opportunity as the most famous fictional planet of Epsilon Eridani is Vulcan!
*but that was located in 40 Eridani, not Epsilon Eridani*
Thank you for making the pluto and this video. It really bridges the gap in high school astronomy to the dense craziest of college astronomy where they talk endlessly about some planet or nebula billions of light years away with no meaning to us or relations towards our galaxy or solar system.
I wonder if any life out there in a different system, has observed our planet and talks about how intriguing the possibility of life on it could be....
New intro? Doesn’t matter to me, just curious, love the work!
Some scientists now think red dwarfs may only flare at their poles. This would make the habitable zone plants safer from radiation
Astro Pro 😁
wow quality content right there on your both channel sir
keep it up👍👍👍
Nice!
Thank you. Very interesting. Btw I am watching you from Russia
You are underrated
you mentioned how one side facing the star (tidal locking) seems to be the norm for planets orbiting dwarf stars,
this is because objects become tidally locked quicker when what they orbit is closer / bigger. This is why the moon is tidally locked to the earth, but earth will not be tidally locked to the sun for perhaps many billions of years, though Venus and mercury are.
There is video in the Cool Worlds chsnnel showing that none of the exoplanets detected so far are really considered habitable. Some headlines like "new earth, earth 2.0" are just to catch public attention.
I hate to be the guy who asks "Link??" but, I'm honestly asking, I'd like to watch this.
I was under the impression there was research about "Goldilocks Worlds" which claimed that K stars were better than even our G star here. Although there was some talk lately that K stars emit almost the same infrared as G stars so the "habitable zone" would likely be just another Venus zone.
Anyway like I said, link plz
An amazing channel. Not only do you not use the words Shocking Discovery in the headline but it's your real voice and sartorial elegance. More importantly, the question you raise are interesting. How would a being living in a twilight zone measure time? And how does the age of a system effect things? I think Epsilon Eridani is a quite young system.
Sartorial. 🤔🤨🧐
Atlas pro = Astro pro
You the best
Epic
All these types of videos should start with the disclarmer "life as we know it". We know so little, it's best not to make too many assumptions about how life can or can't occur out there.
Also I can't image how it would be to live in the moon of a gas giant, and what crazy mythos might emerge from sentient races living in them.
I liked coming back to this after Starfield released to see how many of the discovered planets were in it given the catalog name of the stars in the game
However convenient is the naming protocol for exo-things is, we gotta gives them catchier names then Proxima Centauri B
in the back ground i see that you use space engine. i love that game
I hope you create more videos =(
(This may sound weird) First time viewer here. I noticed somethign about this was.....off. Then i noticed that the narrator's eyes kept darting to his left (stage right) about every 3 seconds. I get why. he is probably glancing at notes or something. It just stood out and now its all i can see
Okay, we have like 4 new vids on this channel, are these reuploads from the og or new stuff? Sorry I'm too sleepie n wanna pass out to his smoooooth voice
More like this
nice
Hey, Wolf 359, I know that name. There will be a great battle happening in a few hundred years.
Space AND biology yes pls
Can u do a video on what’s the solar system boundaries
The blue purple pink planer is so pretty
I like how much your hair bounces when you talk
yes
14:34 Tidal locking can also be on a 3:2 resonnance, like Mercury or Venus, and the planet could have a (quite slow) day/night cycle, which would help to regulate the temperature on the surface quite a bit.
24:50 O and B stars are very unlikely to have any planets around, for 2 main reasons. One, their intense light and UV radiation quiclky blast away and ionize the protoplanetary disk around them, makin acrretion of materials very difficult, if not impossible. And lastely, their very short lifetime (especialy for Early B and O stars) is incompatible with the time necessary to form planetary bodies.
I want to know more!
And to think, if nations could put their differences aside, we could already be well on our way to developing a space shuttle that could hold an entire colony of people and pioneer our way to these new worlds.
Think about that. We focus way too hard on things that ultimately don’t matter, when we could come together for something much greater
Sadly the way things are going. The only rockets that fly will be ones that lead to our doom.
Finding trees would be a good start or actually if we find trees we already found life

I wonder what happens to the older videos. I had them saved and downloaded 🤔
Fun fact: Orange dwarfs are also called Oompa Loompas.
Based video
what about a gas giant in the habital zone? its possible moons could be more likely to harbor life.
I don't think gas giants are typically in the habitable zone for some reason...
It would have to be much larger than Jupiter, possible 10 times as massive and bordering brown dwarf
Has anyone gotten time to find Planet X. Tracking the proposed orbits focusing on its likely distances and then farther and closer . the three prong approach would make many other discoveries along the way to proof to its existence or fantasy.
22:26 panspermia?
Great video I enjoyed it. And you look very handsome and good looking. 😊
Re: Proxima D is likely thoroughly scorched?
I dunno. Remember we're probably talking about a tidelocked world. There could be some pretty unexpected stuff happening so long as it can maintain liquid water on the margin or on the cold side and doesn't enter a moist greenhouse state.
Likely is an important part. It may be what you said but it is probably not. Also, it is too close to its flare type star.
