YESSSSS! Exoplanets and the probabilities of their inhabitability is my favorite topic in astronomy and astrophysics. I've been waiting for this list from you, John! Thanks for making my week! 👍❤
@@bobmorr2892 well around red dwarfs it's highly likely inhabitability 😅. Although David Kipping is doubling down on exomoons. Something I always thought would be interesting. A large exomoon of about the size of mars orbiting a gasgiant at the outer edge of the habitable zone around a red dwarf may be extremely interesting. Tidal forces could provide geothermal heat and help maintain a magnetosphere. The gasgiant may also act as a huge solarmirror possibly refracting only specific wavelengths plus providing most of the magnetic shielding against violent flares from the red dwarf Only slight problem might be the radiation levels around such a gasgiant, but that depends on the distance to and size of set gasgiant. The Jovian system being an example of that. But that aside, exomoons might actually be prime candidates for life outside our solar system. Those moons would also experience tidal effects in their oceans. They should experience quite a few meteor strikes early on due to the gravity well that is the gasgiant they orbit. And last but not least. Being possibly tidally locked to their planet would not be a hindrance for a day and nightcycle because they would not be tidally locked to the star and as such still experience a relative rotation to set star.
@@bobmorr2892 "habitability" has won out, but among those of us with very olde-fashioned orthographical tastes, "inhabitable" remains preferable. By the way, years ago, trucks transporting gas/petrol ⛽were not marked "flammable" but "inflammable". That practice died out, in deference to the many illiterates who thought that meant the gas was fireproof.
To my fellow insomniacs that find great help to put the racing brain at peace with John's soothing voice and interesting content, Sean Carroll's youtube channel is also usable for the same purpose. It is not as good as John's channels, but an alternative once you have listened to all John's episodes a few times already.
:( thats me Over the years constantly rewatching while trying to sleep. Its gotten really bad lately. Sun will be coming up in an hour :/ bad thoughts racing
I always catch your uploads right as I'm getting out of work! It's a perfect way to end the day. Staring at the stars contemplating existence & enjoying the video 😇✨
John. I have to correct you somewhat here. Most exoplanets are found around red dwarfs because they are targeted for having rocky planets with a usually shorter orbit. In exoplanethunting you need a minimum of two transits to have a confirmed exoplanet. Preferably actually three. The fact that the stars in these cases are dim is a nice bonus, but not really that much compared to K and G-type class stars. You were definitely right on the low hanging fruit-case though. With JWST we will hopefully have a telescope that can stare at yellow and orange dwarfs for longer than three years. Kepler fell a bit short in that regard so obviously most of the confirmed exoplanets are around red dwarfs.
The details & in depth knowledge in a JMG video is amazing! Thanks for helping learn more about the wonderful world (universe) in which we Livvvvvvvvvvve ❤ 🌍 🌌 🙌
Certified banger after banger from you! I'm a Biological Science undergrad with a strong passion for astrobiology and these videos are extremely interesting and informative!
Yours is by far the most in-depth explorative channel about the possibilties of extra-terrestrial life, that I know of. Thanks for all the great insights you offer.
I'd never heard of the two Earth mass limit for habitability before. One thing I had heard is that over a few Earth masses, it doesn't matter if it's habitable or not, nobody's getting off that planet with chemical rockets, so they're stuck on their planet for a long time if not forever.
I'll make a video on it some time, there actually are some hard limits there. But there is also a redeeming feature, so sometime in September I'll cover it.
I've heard the problem with worlds much beyond 2-3 Earth Masses is that you start to draw in stray hydrogen and helium, if not from the star then elsewhere. If enough of that happens it becomes a runaway process that makes the thing a Type B (solid-core) gas giant, like our own Saturn. There might be other circumstances--like strong solar winds--that mitigate this and prevent the runaway problem, but never have the prospects for a Krypton-like world looked dimmer. It seems like super-heavy super-Earths just aren't allowed to be a thing in this universe.
John, I have read the Wikipedia article "Hypothetical types of biochemistry", which I find fits super well the channel's theme. I especially liked the section on hypothetical life made of cosmic strings and magnetic monopoles that could live within neutron stars.
I remember when I was a kid and kept googling "exoplanet photos" to see them and be amazed. Little did I know that none were real photographs, but in fact 3D renderings, haha. Good times!
I love my life watching and enjoying your show in a vacuum, because no one I know in this life...watches you too. I however love your contribution. Peace ..
John, I have been following you for years and years... since you had about 5K subscribers. I absolutely LOVE it when you touch on this topic. Your videos are just 👌
Is there any reason life could not be literally every where? They have found bacteria deep in the Earth's crust. What if the 'empty' space in the solar system is full of greatly diluted colonies of extra terrestrial life which can exist floating for eons in a mostly vacuum.
We can't answer that question until we know what it takes to produce life in the first place. We are gaining a better and better handle on abiogenesis, but we aren't there yet. :)
I'll be the doubter. Lots of radiation to cope with and sparse food to eat. Bacteria living underground are using the strategy of living slow and dying old, however it doesn't work if you live slow and die young.
Dang, all these super earth's and I'm imagining the inhabitants of these worlds calling theirs "normal" sized and observing ours as "the tiny planet that could."
Watch listening in the background on my iPad at around 0330 AM up early playing Baldur’s Gate 3 on my PC. Woke up early, hard enough sleep. This video was just calming to the mind and quietness of the early morning to listen to after I woke up.
It's interesting to think of what experiments could be done once we get to proxima. For instance looking back at ourselves and trying to refine our civilization detection methods.
you should do a video on the way time dilation could affect interstellar travel, and whether or not it could be a factor in answering the Fermi paradox.
Another hypnotizingly interesting video. As for the background music, did you compose it? Have you ever thought about releasing a spatial meditation playlist of music like the one’s in the video? Spooky yet powerful….
I'm fairly convinced that Rogue Planets are worth studying more. Of course, them drifting around there in the void makes it difficult. Some estimate that there are more rogue planets than there are planets orbiting stars out there - and even the intergalactic space could be full of them! - On that note, if any civilizations out there DO endeavor to travel between galaxies, I'm pretty sure that they're making use of those for refueling and replenishing resources as they drift through the void ..
Watching your video I was thinking it would be so fun to explore these planets. Then I remember the videogame starfield is coming out Friday! I've been waiting for that game and if I didn't see your new upload I probably would have forgotten until after it came out lol.
The problem is radiation. There's likely lots of rocky planets with liquid water, but your second earth can be awash in liquid water but they will all be sterile wastelands broiling with cosmic radiation if they have no magnetic shield. How common is a liquid iron core spinning just the right way to produce such a shield? How common is such a planet in the habitable zone of a quiet star in a tranquil galactic neighborhood, with a moon and a gas giant in its solar system to protect it from asteroids?
Very interesting that four of ten, including the winner, are within a region that could actually be explored someday (Ross 128, Gliese 1002, Proxima Centauri, and Teegarden's star are all within 15 or so light years away). Even at a speed of 0.1c or less, we could conceivably send a probe there and get some sort of data - maybe not within our lifetimes, but our children's.
K2-72e has an orbital eccentricity of 0.11. While it's likely tidally-locked, would this be enough to give it a spin-orbit resonance greater than 1:1? If so then one side of the planet wouldn't necessarily always face the star. Most exoplanets have higher orbital eccentricities than the planets in our solar system which (except for Mercury) have almost 0 eccentricity, but we seem to always assume that if an exoplanet is tidal locked then it must be locked at 1:1. A similar situation (0.11 eccentricity) for TOI 700d. Perhaps this subject is worth its own video.
At 30% more gravity would you even be able to safely land on the surface, and probably more importantly, would you ever be able to achieve escape velocity from that planet?
Trillions upon trillions of planets and people really think its only us and their religions the truth. I wish i would be alive when humans outgrow this completely.
It's bizzare to me that tidally locked planets could be considered "earth like". It seems like as large a distinction as ones we more commonly use like planets or dwarf planets, or the distinction between planets with or without atmospheres or ice shell worlds. I even think there are probably countless moons that are far more earth like than a tidally locked planet, despite them being a different category of celestial body.
I genuinely wonder if the radius of a planet doesn’t have any real impact on the formation of complex life. Bigger planets require larger life forms to handle the gravitational force, and vice versa. Temperature and atmospheric conditions would be far more important
Nice graphics and narration! What would be nice for you to show sometime is the exact data that they use to make these claims for even a few of these suspected planet characteristics so that everyone can better understand just how much of it is speculation and pure fantasy as opposed to anything tangible! I understand the basic concepts they employ to come to their conclusions, yet I feel that there would be just as accurate of a result if they were to throw darts at a board that was sectioned off! Even a small cloud of particles between us and the stars could render all data useless, and would you believe , it's possible that there are millions or billions of particles between us just in the solar system!
There isn't anything that would come across clearly. The data is a string of numbers for radial velocity, and for transits it's just a light curve with a dip that all look more or less the same. You can see examples at planet hunters: www.zooniverse.org/projects/nora-dot-eisner/planet-hunters-tess As to the cloud of particles, the reason that doesn't happen is because any ambiguity in the signal results in it being tossed out by a computer program. It needs to be a clear, exactly periodic repeating signal for a transit and a clear repeating signal for a deviation in the star's motion for RV. It's like clockwork. Dust won't affect either for exoplanet searches, however. For other stuff it does, such as anomalous irregular dips, but the exoplanets are clear as a bell or they're tossed. The real problem for exoplanet transit searches to be honest are things like starspots that can appear to mimic a transit, but then disappear on later examination.
Yep! That's why it should be shown! So people can understand just how much personal opinions and speculation occurs ! It was just a thought ! I just believe if you gave the dataset to say ten people with no collaboration , we would get quite a variation on the interpretation of the data! I could be completely wrong, but from the data I've seen and what some people say , there must be a large amount of information I don't get to see or don't understand it correctly! Ty for your time !
The saddest thing ive heard today is that within the next couple centuries we may know more about our closest star system...it is all kinda feeling hopeless at this point
2 things I'm noticing besides Earth orbiting this type of sun: 1. Earth is rather small as a planet in it's position in the solar system compared to all the planets introduced by this video (thus smaller could have more chances of hosting life?) 2. It's more likely to host conditions for life being a planet closer to Venus (as positioned in the habitable zone) rather than to Mars..(making me wonder if the problem with green house efect is rather preferable..than an ice age)
Why earth is special 1 Right size. 2 Right distance from its star (sun) 3 Right type of star 4 Right tilt 5 Right rotation speed 6 Right sattelite (moon) at right position 7 Working magnetic feild 8 Right solar system (Rocky planets near star protected by gas gaints farther away from star. 8 Right neighourhood around sun (supernova explosions bombarded earth with valueable minerals and substances. 9 Right position of Sun in galaxy. 10 Right type of galaxy. From this their is a chance their might be just around few thousand planets with life in universe. All this cannot be empty.
I wonder... Red dwarves are most numerous stars. But... Could there be "brown dwarf" systems out there...where central body is a brown dwarf...where it wasn't massive enough to "ignite"...but may have a system of plants/moons orbiting .? I'm betting such systems exist in abundance.
I seriously appreciate the fact that John regularly uploads right when I'm about to go to bed.

2. It's more likely to host conditions for life being a planet closer to Venus (as positioned in the habitable zone) rather than to Mars..(making me wonder if the problem with green house efect is rather preferable..than an ice age)
Why earth is special
1 Right size.
2 Right distance from its star (sun)
3 Right type of star
4 Right tilt
5 Right rotation speed
6 Right sattelite (moon) at right position
7 Working magnetic feild
8 Right solar system (Rocky planets near star protected by gas gaints farther away from star.
8 Right neighourhood around sun (supernova explosions bombarded earth with valueable minerals and substances.
9 Right position of Sun in galaxy.
10 Right type of galaxy.
From this their is a chance their might be just around few thousand planets with life in universe. All this cannot be empty.
If you could communicate with the other side of the galaxy you should be able to put the house on Zillow
If you say "TOI 700d .93 ESI" to someone without context, they will think you're speaking gibberish.
