There are no known habitable exoplanets 

edit: i changed it ok so this video has been out for about a week now and a lot of the comments are mad at me for making clickbait, so i’m gonna try to clear that up in one comment when i was writing this script a few months ago, i had just gotten recommended a bunch of ai generated clickbait bs that inspired me to make this. I put “there are no habitable exoplanets” as the title as a direct response to the titles of the other videos, which were saying stuff like “these are the most habitable exoplanets” this video sat on the back burner for a few months until i finally got around to publishing it, and I didn’t bother to change the title the title is not arguing that habitable exoplanets don’t exist. I say in the video that they probably do. If anything I should’ve added quotation marks to the title (there are no “habitable” exoplanets) to make it more in line with what i actually wanted the video to say (which was meant as a direct counter to the ai misinformation that’s everywhere) but I forgot to do that, and overnight this became my best performing video ever, and now i’m scared to change the title for fear that the whole thing will just die my goal isn’t to misinform people. I actively try to avoid clickbait as much as possible, and I research my videos for months before publishing them. When I made this title, clickbait genuinely wasn’t even on my mind, “there are no habitable exoplanets” was just my first automatic thought (and if you check my other videos you’ll hopefully find this is true, my other video titles are usually very simple and non-clickbait. This video is very much an outlier) So sorry if you feel clickbaited, but that honestly wasn’t my intention. I had no intent of making the video clickbait, and at this point i’m scared to change it because it could kill the video’s performance, and I feel as though this is an important video to get out to as many people as possible, since it’s directly countering popular misinfo i’m not trying to make excuses, i need to hold myself up to a higher standard so i don’t become the exact thing i’m trying to stop, and ig i’ll just remember to revise video titles in the future essay over

The funniest joke in the universe would be that theres another intelligent lifeform out there, but they see Earth as unfit for life because they think non-ammonia breathing lifeforms an impossibility.

There is no easter bunny, there is no tooth fairy, and there are no habitable exoplanets

I wonder if somewhere in the universe, there are aliens sitting on a frozen, radioactive hellscape with crushing gravity thinking "damn, the fact that this planet is so perfect for life is such a miracle it shouldn't even be possible"

"Yay, we finally found a habitable planet!" ... "How do we reach it?"

A majority of humans died on earth Conclusion: Earth is the deadliest planet

instead of terraforming other planets to make them habitable, we should look a bit closer to home and terraform Detroit.

This video is far better than most largely because the narrator is more interested in practical facts and scientific accuracy rather than self-promotion via BS and clickbaiting. How refreshing, thank you.

"Are you habitable because you're earth or are you earth because you're habitable"

AI generated "education" content on RU-vid is genuinely a huge issue, and a giant tragedy. I sincerely thank you for noticing the issue and attempting to fight it off. I also entirely agree with your point. Do habitable exoplanets exist? I can say with near absolute certainty, that yes, they do But when our sample size of "well understood exoplanets" is like, 4, with everything else being basically guesses, of course we haven't found any Earth clones yet.

'Planets don't have to be habitable to be interesting.' I know it, you know it, everyone in this comment section knows it. But for the vast majority of people, they don't care unless it's habitable.

Its so refreshing to find an astronomy channel that isnt AI, misinformation, and clickbait

The G note that plays every time you talk about a new planet reminds me of when i was a young boy and my father took me into the city to see a marching band

Perhaps the real exoplanets are the friends we made along the way.

even if theres water, life, and a magnetic field, i guarantee you we cant breathe any exoplanet atmosphere

I disagree. I've seen australians on all of them

There’s no girlfriend, there’s no half life 3, and there are no 100% habitable exoplanets.

I’m so tired of headlines screaming “NEW EARTH FOUND CLOSE TO US!” First, it usually at least 40 light years away (which is close astronomically but 50,000 years away with our current technology.). I have a feeling that bacterial life might be fairly common, but having bacteria is not the same as having intelligent life. (That requires an environment that is suitable to complex life, and that environment must be fairly stable - not given to extreme swings in temperatures.)

1:13 when i was a young boy, my father to me to nasa, to see an exoplanet

This video is unfortunately attracting all the people who watch the 3 hour AI future civilisation videos and actually take them seriously.

What scares me is eventually when we find the PERFECT habitable planet, we'll discover it has an alien ecosystem that would kill us instantly due to no immunities.

Some people are getting confused. He's not saying there aren't no habitable planets, he's saying we haven't found any yet. And may never find any. Or it might happen tomorrow. We just don't know yet. Sometimes "we don't know" makes people uncomfortable, but there's nothing wrong with it.

It's almost like we evolved to live on this planet

Probably the reason we didn't find any Earth-Like worlds is because we're not very good at finding exoplanets (yet). If you check an exoplanet mass distribution graph, you'll notice most of them tend to be massive, and there's almost none under earth's mass. Exoplanets that are not too large for life are pretty easy to miss.

I think the reason we haven't found any viable habitable exoplanets is simply due to the lack of data we have. We've only been observing exoplanets for a little over 3 decades, with most of those planets orbiting perilously close to their parent stars (primarily red dwarfs), and/or are Gas Giants and Super Earths/Sub-Neptunes, mainly so because they are very easy to detect. We have little data on Earth-sized exoplanets orbiting Sun-like stars because they're so much harder to detect, due to their much longer orbital periods which makes it hard to verify their existence via transit methods (which is the most common method). Our exoplanet catalogue will continue growing over the next couple decades with more powerful telescopes, and as telescopes become more powerful and our observational periods grow longer we will probably have more data on habitable exoplanet candidates.

That G note at the introduction of every planet triggers my MCR recollection. Everywhere I go, sometimes I get the feeling that they are watching over me... Informative video!

About 2 years ago, I got in a spat with some random arguing that the AI generated images were the actual planet and what it looks like, after i told them we don't have the tools to actually see the true exo planets and what it truly looks like. This channel is such a breath of fresh air. I love it.

People don’t seem to understand how insanely rare and specific the conditions that life requires are, and that’s just what we know definitively is necessary. Even earth couldn’t have supported life for most of it’s existence, a real habitable planet isn’t something there must be a bunch of that we’re just bound to stumble across eventually it’s amazing that even one exists

Everytime that piano key plays whenever you bring up another exoplanet, I was immediately on Black Parade mode.

The amount of people immediately recognizing a g note because of a song is hilarious

As an astronomer who studies super-Earths around dwarf stars (like the ones you mentioned): THANK YOU! This is the most accurate video I've been able to find about 'potentially habitable exoplanets'. And it's really well-produced to boot! It sucks that we haven't found any... but we're doing our best lmao

People also don’t take into account what part in time a planet is currently in. Remember, for the vast majority of earth’s life, she was completely uninhabitable and devoid of life. A billion years ago a hypothetical civilization could have gazed upon earth and said the exact same things we say about other planets. There was even a billion year time stretch where earth COULD support life but still had none. There were plenty of times where life was wiped out and plenty of times where it sprung up. Some of these planets could have been way past their prime or haven’t seen their prime. Or(which is more than likely the case), won’t have a prime at all. And I think this is vastly overlooked

So far we've found: Piles of gas giants Giant balls of lava Irradiated wastelands Colossal rocks with crushing gravity Big Mars Big Europa Whatever that one carbon pulsar planet is There's so many things that need to go right to get a habitable planet, I'd wager there's only a few in the galaxy

There are no "known" exoplanets that can definitively support life. That said, there are about 200,000,000,000 stars on each galaxy and about 4,000,000,000,000 known galaxies. We have a long way to go before we can definitively say we are the only ones

I really appreciate this. It‘s hard to find quality space-related content online because people‘s approach to the topic is completely warped, ie: drawing interest from science fiction instead of viewing it in the same light as nature on Earth: simply appreciating it the way it is, not depending entirely on mystery to be interesting. I couldn‘t exaggerate how incredibly rare this is.

Hot take: Those planets are not habitable by our (humans or earthlings in general) standards. Different species have different habitable standards.

Finally, SOMEONE THAT ACTUALLY KNOWS HABITABLE PLANETS WITH MICROBIAL LIFE IS RARE!

A planet being cold is not necessary a killer deal for life, anyone traveling past in the cryogenic geological era when every surface land in earth was covered by kilometers thick ice sheets would have thought that earth is inhabitable, there was very few sign of life back then but life survived close to volcanic vents.

So much effort is put into finding habitable exoplanets, when we have a perfectly habitable earth that we’re not taking care of properly. No dream of space life is more important than protecting what we already have here.

While there might be a habitable exoplanet out there, such truly Earth-like worlds would be VERY RARE. Even if we do find life on other planets, their environments would probably be vastly different and hostile to life from Earth. And we don't know much about planets outside our solar system. We only know about their mass, size, and distances from their parent star(s). A big issue with most "Earth 2.0's" is that most orbit M type stars. Which are not only VERY VIOLENT, but also any planet that orbits them in their habitable zone would be tidally locked, meaning one side is an endless day, and the other side is an endless night.

This raises the issue of the relationship between reporting on the findings science and the actual findings of science. Over reporting of what's happening in the scientific community is an issue that has been going on for decades.

Every time you hit that piano note i think *when u was, a young boy..."

Habitable for us and habitable for life are 2 different things, but i agree none of these planets are probably habitable but they are still interesting and they probably wont kill us right away.

THANK YOU FOR THIS VIDEO. I've argued million times with people who don't have a clue about what makes planets 'habitable' and next time I'll simply point them to this video and save my time and energy.

We can’t be the only ones. We just don’t have the tools to find other habitable planets

"But we can terraform it!" Strawmanbro, we can't even terraform Earth. The technology we'd have to use to get from Earth to another planet though would be useful as that's where intelligent life's future is; between the stars, avoiding catastrophe, not sitting on a rock waiting for an extinction event.

I would like to consider the likely sampling bias effect in all of this. The fact is that it is much easier to find larger planets, because the gravitational effects on a parent star are more obvious. It is also easier to observe larger planets that transit red dwarf stars and orbit closely. That means that the atmospheres of these planets can be observed.. There are also just many more red dwarfs than sunlike stars.

With such a small sample size; the idea that we've found a candidate that's even slightly likely to support life is extremely encouraging.

I can hear black parade from the transitions

I rlly appreciate you focusing your channel on real science and not clickbait, makes the subjects u cover so much more interesting

At 1:14 I really thought “Welcome to the Black Parade” by My Chemical Romance was about to play. 😂

The biggest take away is that the singular piano note you're using makes me think about when I was a young boy.

that G note scared the shit out of me

RU-vid has been recommending me underrated gems lately. You are one of them. Concise and critical minded, digging away all the media sensationalism designed to generate clicks at the expense of nuance in this short attention span economy. Just mention temperatures in Celsius too

all these planets are literally just "earth similarity: 98.6%, life likelihood: 0%"

Also remember habitable doesn’t necessarily mean “habitable for humans” just that life “Might” be there

STOP PLAYING THE G NOTE

I think it's kinda wild that people are already speculating on whether or not a planet from another planetary system is habitable for life or not when we don't even know if a moon within our own system is habitable or not.

8:21 mouse click.

1:15 I thought The Black Parade was about to start playing 😅

When I heard that one piano key play my brain immediately started playing black parade

The only problem is that it's terrestrial life being compared to extraterrestrial worlds, most if not all Terran fauna and flora would not survive on other objects such as Titan, unlike its potential native Titanean fauna and flora which are adapted to the object's specific environments, and Titanean fauna and flora wouldn't survive on Proxima b unlike its own potential native fauna and flora. And I would've loved to have continued the comment using your own words but B&Q decided grey triangles is an appropriate thing to associate with garden hardware. Oh I _love_ it when that happens.

1:14 WHEN I HWAS, A YOUNG BOI. MAH FATHA. TOOK MEH INTO THA CITY, TO SEE A MAHCHIN BAHND

Everytime that G note hits man..... everytime..... *Grabs eyeliners*

I don't get why a lot of the planets peoples are pushing as habitable orbit flare stars, when there are at least a few red dwarfs nearby that are Far calmer. Luyten's star, Teegarden's star, and Gliese 1061 are all red dwarfs that flare Far less than most other red dwarfs, so even if their parents Did emit more flares in the past, they should have had the opportunity to re-generate an atmosphere.

Gave me a PTXD flashback with that G note

That G note havin me flashbacks lmao

"more better than earth" then it has 97% methane, an average temperature of 450 degrees celcius, and literally has too much pressure and gravity.

Bro hates fun and dreaming. Gotta respect it honestly, I’m subbing

I agree with the general idea of the video, but it's important to be precise if we are going to criticize other science communicators. For example, he shows, convincingly that Kepler-22 b is very likely not to have life that evolved from the circumstances we suppose life arrived on Earth. Please notice that abiogenesis is an open problem. That is not the same as saying that Kepler-22 b is not habitable.

I can't stand those AI channels. If they are using an AI voice, that immediately tells me they're not above AI scripts, AI imagery, etcetera. And AI hallucinates, that is the Achilles Heel of AI that will never be "fixed" - so, you should never get your facts from AI, making AI-voiced channels one of the worst places you can get your knowledge from. Thank you for putting this out there!

I agree with most of your points, but its worth noting that a lot of the information we have about these planets is constantly changing and could be incorrect

"Earth like planet" and its raining acid

We now know that TOI-700 actually has four planets, including TOI-700e which orbits a bit closer than TOI-700d but still within the habitable zone although it is only about half as massive.

I like to imagine some government spending billions of dollars to send a probe to k2-18 b and then waiting hundreds of years to get anything back only to find out that it's literally hell.

I love your videos, I always learn something interesting!! Thank you for your work!

*Talks about Kepler 22-b - plays a G* *Talks about Kepler 186-f - plays a G* Would be so cool if the ding would correspond to the name of the planet. 🎹

Also, a magnetic field is important

0:08 can you make a video about these ai generated video channels? I think I saw some of these

After a series of browing through the Wikipedia list of potentially habitable planets, I have brought the list from 65 down to 21 realistic candidates. These are all the planets that I think actually have a realistic chance of being habitable (keep in mind my primary source for this was Wikipedia): - Gliese 667 Cc - GJ 1002 b - GJ 1061 c and d - K2-72e - Kepler-62e and f - Kepler-186f - Kepler-296e and f - Kepler-442b - Kepler-452b - Kepler-1229b - Kepler-1649c - Luyten's Star b - Teegarden's Star b and c - TOI-700 d and e - TOI-715 b - Wolf 1069 b Which one of these do you think is the most likely to actually be habitable? Do you think I forgot a planet? Or would you remove some of these planets from the list? Feel free to let me know :) Also, this sorting is mainly based on mass and radius. Most of these planets orbit red dwarfs but I still decided to include them simply because their mass and radius is similar to Earth, which means they're most likely rocky.

Tidal locking doesn't preclude the possibility of life.

I think it says allot about humanity they we would rather attempt and fantasize about terraforming literal hellholes than simply take care of the rare paradise we already have

cannot believe i just got G note’d in a space video.

loved this video. I also hate the pop-astronomy side of youtube that's growing recently, but in the end it's just simple click bait, nothing actually harmful

Hi, loved your video, however where can I find the sources you used to talk about trappist 1 planets, especially trappist-1d, because I couldn't find any.

"Let's start with Kepler 22b" *plays a G natural* nice

"Habitable" is relative - other life forms can exist on planets where humans cannot. We can't go to the bottom of the ocean but some animals thrive down there. It's a matter of time before we find life in the universe - I highly doubt that it will be in one of these so called habitable zones. My money is on life being found on Titan.

Earth is habitable, therefore there must be other planets that are as well. Its not mathematically possible for this not to be the case given the size of the universe. Anything that happens once must happen many times

We will never even get to them. The space between systems is too vast to traverse, even at light speed which is impossible to get too

These planets may not support human life, but they can support alien life with different metabolism/evolution. For example, a new thermophilic/thermophobic microbe can evolve and live on these planets, we just obviously can’t see them from Earth. The important thing is that these planets CAN support life that is close to Eartg-evolved organisms.

Can you please provide the research in the description, I love the video but I'd like to see the research you did.

whats with the G note

Yalls forgot the ocean planet 4546b i think its pretty good

First video I've watched on your channel and I love it. Love the realism. Subscribed

This is great and I appreciate you directly responding to those who claim there are planets more habitable than Earth, make clickbait-y thumbnails and then make poor quality videos, but still receive the views. It is a shame and your channel deserves more respect.

1:14 WHEN I WAS

Imagine there’s aliens out there thinking our planet is too hot and the oxygen here is poisonous ..with too weak of a gravitational pull

Hey, at least Kepler-22b is a good song.

How to find a habitable exoplanet: Step 1: leave the solar system Step 2: look at planet Earth Congratulations, you have now found a habitable exoplanet!

Born too late to exterminate mega fauna. Born too early to terraform other planets 😢
