Other Earths: The Search for Habitable Planets - 4k
- Опубліковано 20 бер 2023
- Our galaxy is made up of some four hundred billion stars and at least a hundred billion planets. How many are like Earth, with an atmosphere, flowing water, complex geology, and abundant life? Astronomers are seeking answers in countless photons racing past the Earth and in bold new theories about how planets form and evolve. What they are finding has only sharpened one of the oldest debates in science: Is biology a powerful and inevitable byproduct of cosmic evolution? Or is it rare, in a galaxy shaped by violence and mayhem?

Many heartfelt thanks to everyone involved in bringing this production together. I thoroughly enjoyed it! Fantastically interesting material, great narration, wonderful music. I'll continue sharing these with as many people as can stomach them hah. Please continue the great work!
We don't need constant music, all American docs do it in case people will switch over, such is dumbing everything down to the lowest common denominator in the USA & advert breaks every 5mins.
I don't believe your thanks is actually heartfelt..
I can't resist myself when i see space documentary. I never thought it's a waste of time, even if i didn't get anything out of it. I just love space
Do you believe in Jesus?
Can humanity truly grasp the concept of how enormous and incredibly dynamic the universe really is! It's like we are a single atom within a grain of sand out of every grain on this planet. This is exactly how I personally gage the vast expanse which is our cosmos, and to only image, our universe might just be a single bubble out of an infinite number of other universes....it's staggeringly mind blowing!
Bc we exist in the material version of now, The only definitive thing that makes sense to me as far as where all of this ends, I think that after this lifetime or possibly many lifetimes, when we finally exhaust our physical bodies and this whole 3D material experience expires, and we retire back into pure energy, I think that's when we absorb the unified understanding of ALL THINGS and questions.....
While present in the material world....we take on a totally different concept of existence. Earth, it's like a teaching school for refining the soul.
Advancing spiritual knowledge!
It's a never ending story bro.. Who ends all this ??
@Steve Hopkins .l.p..op
Well said it truly is amazing just how small we are compared to the universe just makes you wonder der
This was a totally enjoyable, well made and interesting production. Truly great thank you. There is a video around of the life and death of planet Earth which shows the incredible events that took place on Earth for life to begin, some of them so unlikely to happen the odds are almost impossible. When I think of that video and combine it with this one in my head, it becomes clear to me that the chances of finding other planets with sentient life forms on are extremely unlikely. With the 'numbers game' we could say there are so many planets in the Galaxy there Must be planets with life forms on but I think they will be a very very rare occurrence. I am not sure that we are alone, but ourselves and any other civilizations out there are probably very very lonely! Out of 100 Billion planets it would not surprise me if there were as few as 100 other civilizations in the Galaxy or less and that some of those are developed or seeded from pre existing civilizations. Although the Mathematical numbers of planets is huge, unfortunately so are the odds of the string of events required to create sentient life forms.
@Tigs2 What does alone mean to you? Can you define what the word 'alone' is? I don't know what's on your mind but the truth is that we're not even alone on the planet let alone the vast universe out there.
@F5 there is nothing ‘deliberate’ about it. The facts as we no them and the science have persuaded me that the odds of intelligent life out in the Universe are extremely high against. I would very much like there to be other Alien intelligent life forms but the current science/mathematics suggest a different story. I used to be an advocate of the ‘mathematically there must be more intelligent life forms’, but since i have learned the extraordinary conditions and strokes of luck that led to our evolution i calculate that replicating that type of series of events is so implausible that i am left with one sad conclusion - we might be alone.
Why are you deliberately denying intelligent life beyond earth? I am not saying all the planets in the galaxy have life but some of them could have intelligent life even they are many times smarter and more advanced than us humans. Our senses are very limited to being able to know what's going on out there
ALLAHU AKBAR THE CREATION OF ALLAH IS GREAT & PERFECT THATS WHY ALLAH MENTIONING IN HOLLY QURAN
Very informative and easy to understand
Thank you for your work
This is so fascinating on so many levels, thank you guys!
I dont know how much of my time i’ve watched documentaries about the space and related stuff… and still love to do so.
Un🎉😂 jjj😢uuu🎉😂😢 bbb uuu🎉😂b😂🎉
Science related documentaries tell I fall to sleep for like a decade .😊
Not only u me everyday before I sleep I play this n sleep
I'm glad I'm still alive to see something like the JWST
The clarity and the fact that all the discoveries will come fast.
Plus we will realize what we need on the next Gen of satellites sooner than predicted.
We are crossing the threshold to the next stage in space discoveries, technology and perhaps new ways to understand how it all works
I've been layed down watching this in amazement. fantastic work with the knowledge and research put in this
I've had a question about the transit system for detecting planets for years, and no one still has given me an answer, nor have I heard anyone talk about this aspect I've been wondering about. If in order to see a planet transit in front of its star it must be on the same plane made by that star and our Earth, or not too much off it; doesn't that mean that there is still 180 degrees (or let's say 170 to 160 degrees) north and south latitude on that star or rather on other stars, where there may be planets orbiting except we don't see them because they don't transit in front of us? Doesn't that mean that there must be at the very least 10 times more planets that what we have found and will find still ?
Crazy to think, i've been watching this channel for about 11 years now, and i still get excited and super happy when i see a new SpaceRip video sitting there waiting for me, been a long journey of incredible content with this channel and i look forward to many many more to come.
@David Sheckler OMFG I said try harder boi, do you have like reading problems or what lmao
@DOGE[tm] responds to old comments Triggered 😅😂🤣
@David Sheckler Wow, totally haven't heard that line before. Try harder boi, or you're gonna bore me to death 🥱
Amazingly explained. Watching it while medicated is next level of understanding. Endorphins, seratonin, and dopamine dancing in my brain, love it, best feelings ever. Cloud 9 imagination
@noe rodriguez fire strain of marijuana
What's that medication called?
@John Dough I used to smoke weed everyday for 35 years. Maybe once or twice a month now. Quit drinking about 3 years ago. ✌️
@John Dough it does wonders for me
@Randy Gip , weed suck. I still have joints I havent even touch
Curious about those 1/2 and 1/2 planets that are tidally locked. Wouldn't their orbits be unstable because of the difference between the sides? After all, miles of ice are much denser and heavier than dry deserts. This should keep "tipping the planet over" as it rotates the sun or does all that ice piled up on the far side create a stable lump that can't rotate due to the difference in density?
Whenever I'm bored, I would just take off and go on a tour of the Universe...it is so refreshing!
True we are connected with Universe
One thing that is good when it comes to science is its reality and discovery!
I'm thinking that a large fraction of planets in the galaxy are in orbits nearly or exactly perpendicular to our view, so we could see only one hemisphere as they orbit a star and rotate, and since they wouldn't pass across our view of the star, could we observe them with anything other than the stars' wobble? Like viewing Earth from straight "above" our orbit and seeing a pole and hemisphere north or south. Just wondering what percent of planets we can really detect.
This channel is so underrated. You guys hve earned my subscription
I wonder how much it would cost to maintain one of those large telescopes each year.
People can't base what they know as life as the standard for all life. Perhaps life does not have to be carbon based or dependent on liquid water. People have so much to learn and comprehend if that's even possible.
I must truly agree..
@Craig Reyneke how do you know if there is even more. You don’t. Carbon based life is probably our best chance to find other life that’s just facts. Think carbon as the Majority and other based life as The minority. Why would we waste Resources trying to find 5% when we could look for 95%
Glad to hear you say it. We as humans are too arrogant to believe only our understanding of what life is is the only possible form life can take. To become more enlightened we just have to look into space and its incomprehensible dimensions and realise we know very little of what's actually going on around us.
Carbon based life is probably the most common so searching for that isn’t a bad idea
I love to watch these space documentary. It teaches me lot about earth and the planets in our solar system and the universe, i hope that they will find another world with water on its surface
I literally read 100 books on astronomy but this channel gives more knowledge about it
So glad to see this channel fully restored after that hacking fiasco!🎉
I love all this stuff man! I really do. But here’s my thing, CAN there be any sort of advanced life forms, be it organisms or plants, up to creatures and beyond? Sure. I’ll explain it like this, it happened here, so why not? The word “can”, doesn’t mean “will. It’s like dropping a tiny little bibi gun metal ball into the sea anywhere in the world and expecting some human finds it once day (assuming They could track it and if they ever see any anomaly, you’ll know a fish ate it and so forth) That’s what it would be like finding a bibi in the sea. Almost next to impossible. So yea I can see plenty of planets with life on them, the distances needed to find that out are mind boggling for those civilizations who figured it out and can do it, let alone dreaming it up and doing it.
I have to say your content is very impressive I enjoyed it you had me at the end of my seat I am now subscribed‼️👍🏾
The Question Shouldn't Be...
How many Earths are out there?
It Should Be,...
How Exactly are we going to get there?
Thanks for another excellent video
These always make me feel so small but so grateful we are so lucky to exist!
Thanks be to GOD for life
I try to watch all the space video content with the good commentary and the best graphics. It literally takes your mind out of this world.
@SpiritualBeing 😆 🤣. It really might b safer in space lol. If they could make a city size spaceship in space so we could still do things we do on earth to have fun like amusement parks and play sports then im all wit it.
@Troy Wilson I much rather get hit by a meteor exploring space, than get hit by a car on earth lol
@SpiritualBeing I want to see it for myself too but im scared the spaceship might get hit by a meteorite or sum and cause a major problem smh. If it had a shield around it I would feel better going. I want to go to another solar system or galaxy. Our life span not that long to make it smh 🤦 😪
@Troy Wilson it does me the opposite I’ve spent hours and hours watching anything and everything about space. It’s bittersweet because when I watch I feel home sick and sad I can’t go up there and explore myself, but fascinated by the abundance of beauty and all the possibilities.
@NO USE FOR A NAME i cant never finish watching it cause it makes me go to sleep not saying its boring but it make my mind zone out and that puts me out lol. I dont even have to b sleepy sometimes.
The fact that you approached a subject I have thought about is much appreciated . Now I know Nasterdonis was wrong , well at least for another 3 or 4 hundred years give or take . Lol .
The science / astronomy world learned a lot from the Arecibo Telescope in Puerto Rico, but after James Bond / Brosnan had a violent fight with Sean Bean on the structure, they broke many of the metallic beams which held the scope in place, creating a weakness in the framework & the reason it would crash in on itself a few years later. Oh well :(
How unique you are, human beings. Like how not one snow flake that ever fell is identical to another, nor is any two plants or leaves identical, identical twins aren't even exactly identical. Nature is telling us something. Telling us how unique we are, there is just us out here in this never ending universe
@Las vegas Otis thats the nature of scientific theory, it all starts by reaching out with imagination and then finding proof for it. But some subjects and theories as they stand may possibly never be proven or disproven.
@Galejro I gave you a like for your comment, and I appreciate it, but you might be reaching.
@Las vegas Otis I think he refers more to sth like cardishev lvl 3 civilization. We define intelligence and life through our perspective. Life can be as alien to us as it can that was shown in Life Beyond 2 and 3 by moldesheep.A civilization of lvl 3 cardishev may be so advanced, us humans dont even register as intelligent life to them. Like when we consider supernatural and divine what if that is an alien civilization just screwing with us. What if they are so advanced their entertainment is to create a planet and play with its civilization. Simcity 4 million session that spans eons. If we consider that, earth, us and all life here is just part of alien fictional universe as mere npc characters, than truly our definition of what life is and what intelligence is is truly false to what is real, cause we are to them like super mario is from an old nes console to us.
@NickRamone0 you are life itself
@bdizz77 life or "intelligent" life? What we consider life would inevitably be a projection of our human consciousness. What if life is something unfathomable and incommunicable? Somethinf formless and immobile. Alien life would probably make us feel much more unique and alone than we did before discovery.
This is Awesome... Love watching this Documentaries.👍🏻👍🏻Great Job!... Thanks.
documentaries about space and stuff are one of the best documentaries that everyone will ever see
I've been watching SpaceRip videos for more than a decade, since I was a 13 year old who liked space.
Today I'm an Astrophysicist, actively researching exoplanet atmospheres to determine their composition and structure.
These videos were one of the bigger influences on me and my chosen career path.
I was also really passionate about space and chemistry back in high school, both of which never came into fruition due to my poor math skills. Ended up doing BA psych, which is interesting but I wouldn't say it's my passion, and career-wise it's kinda eh. I truly feel happy to you and to others who manage to live out their passions, must feel great 😌
@rocky_racoon_UK area 51 🛸👽😆
live the dream
Thats awesome. I just got into space exploration videos and im 39 😆 but i love it knowledge is power
And if we found a habitable earth like planet out there the question is: How do we get there?
There was a science documentary I used to watch with floating robots that were sent to other planets in search of life. Whenever the robots encountered an alien creature it would play a video mapping out where earth was, show humans, etc. I haven't been able to find it in years. Does anyone know what I'm talking about?
Thanks a million to the providers of knowledge
There's definitely life on other planets, and may even be intelligent life! The sad truth is there are no 2 places harboring life close enough to each other, or has developed on the same timeline of a planet lifespan.
@Keith Chamberlain at least that’s what we’ve been told is that we haven’t found any yet
Is that not what I said?
"There's definitely life on other planets..."
We don't know that. Neither do you. We've found none yet.
I remember when our galaxy had 100 billion stars. Stars increasing faster than fuel prices
Everything that ends, begins again, a cycle of death and life, light and darkness. We are as eternal as the stars, because we are made of them. Our world is one of billions, and we were never, alone.
spacerip doesn't always come out with stuff, but when it does? damn its good!
Thank you for this .
I can't believe it took us this long to know that every star in the universe has a solar system orbiting it. We thought that our sun was special and the only one with numerous planets but now we know that there are more planets than there are stars
I agree 100 percent, but there are people on Planet Earth that still believe we are alone in the universe. They even think we're special.
@Bony's Miniature's We are still understanding things about our own solar system that created an environment for life. It's impossible to know wirh any certainty that there is intelligent life elsewhere. For example, they now believe the larger gas giants in outer sphere help shield earth from destruction. And that the magnetic field of earth's core is vital. A planet being in habitable zone is just a smidgen of what it takes to have human life. Statistically, the odds are favorable for somewhere. But I would still posit that it would be extremely rare. And we'll never have definite proof. It's simply too far away. Calculations alone simply don't get us there. And science proves itself fallable almost every day. After all, at one point, science said the earth was flat. Lol. Still a lot we don't know or only think we know.
@A Havens not possibly its practically impossible for not to be other intelligent life , statistically
User Search Not Found many have life as life is part of nature this universe is equipped to host life
The Universe is enormous and has billions of galaxies, surely somewhere there is an intelligent alien civilization either in our galaxy or in the other galaxies. Maybe there are not advanced enough to reach us.
While I agree other life exists somewhere. That does not mean that intelligent life as we know it, exists. If it does, it's certainly highly unlikely that in the timescales of the universe two intelligent life forms will overlap in technology so they can communicate or even visit each other.
Life on earth is so intrinsically linked to the myriad properties of earth and this solar system that I postulate we cannot survive as a civilisation in space, or on any other planet.
I almost guarantee nobody procreate on another planet, even one as close as mars. Just think of the millions of years of evolution that happened on earth and think of all the various properties of earth that will have affected the lines of evolution from the very inception of life.
Or they are limited by the speed of light
Space is cosmic 😁💪🙏 full of life 🧬 I hope
It turns out the more we find out about our planet the more rare we become and if there was other life out there it would have to be carbon based life so they would be very similar to us if not the same so we are made in the language of the universe, makes you wonder.
I'm taking an astronomy course next quarter, I can't wait to ask my professor why there's always orchestra music in space
Haven't seen one yet better than the 🌎 Earth
I've been into astronomy ever since I could remember, they have found interest earth like planets, but they are too far and they just can not see life on them, til now we just don't know til life is discovered and I'm a firm believer off other life out there firm believer
I love planets and space travel
Most of the videos that lull me to sleep were about space and its calming narrations
Life exists somewhere out there. Just look at us and how much life varies just on this planet. Its gotta be out there somewhere
Exactly! I look at the universe like our oceans.. teaming w life
It's not a bad thing to realize that I'm nothing more than a intelligent speck of dust. Even when my intelligence leaves my body I'll become millions of specks of dust traveling the universe forever.
Imagine being the human to step foot on another earth omg
I'm pretty sure there is some intelligent life in the Andromeda galaxy so maybe they might want to point the radio telescopes at that.
Another good Head Feed. Great work.
How do they know these things from taking pictures as far as how hot or cold a planet is or if it has atmosphere
the sound of this commentator's vocal is mastered so good. very impressive
If there are other Earth like planet it will be very easy to find. If it has intelligent life you will see lights on the surface on the dark side and if they are intelligent enough you will detect metallic satellites around the planet
Earth didn't have satellites until very recently in its history. There could be life that is equivalent to our culture around 1000 years ago. I still think intelligent life is extreme rare.
@michael truitt then we could see there big ass ship's orbiting the planet that there at. I think. I hope
what if they are so advanced they just planet hop they wouldnt need satellites or a home planet if they have big ass ships or what ever
This was a hell of a trip
At 19:50, I couldn't understand "47% less massive but one and a half times its size".
So far, "massive" cannot be directly related to mass, correct?
I'm not an Astronomer but I do watch SpaceRip!
The divine beauty of the universe,
a visit to the universe
Going to sleep material at it’s best👍
Even if there are other habitable planets, it would take 100's of years to get there.
not hundreds but thousands and millions to billions of years
Its just bad we will never know how it is
I love science, physics, and astronomy so much. Yet i am too dumb to get a degree in any of them, sad to say but truth needs to be said. I hope one day we will find an actual exo-planet out there in our lifetime that facilitate life.
Great, thx for the upload!
In the near future the people of Earth might send a research team to check out a habitable planet. Using the technology of the day, a 200 year journey in cryogenic sleep would bring them there. What they might discover there could be a tribe of humans that speak a similar language. They, too, came from Earth, but left 100 years after the first ship and technology of their future time brought them there in weeks, not 100’s of years. Imagine the looks on the ancient researchers’ faces as soon as they found that out!
I know damn well that we can't be the only earth planet in our galaxy
or the only habitable planet in all the millions of known galaxies...
we will never catch that place, ever. But a awesome dream.
This guy ain't no Dick Rodstein, but who is? Thanks for the content Space Rip.
"If I have all the knowledge and understand all mysteries yet, I don't have Love, it's worth nothing!" St Paul....🤔🕊️☝️
Nice! Your videos should be seen by more watchers. Can I repost your channel without changing anything on the clean platform named Ganjing World? Thank you!
“The learned men, that have fixed at several thousand years the life of this earth, have failed, throughout the long period of their observation, to consider either the number or the age of the other planets. Consider, moreover, the manifold divergencies that have resulted from the theories propounded by these men. Know thou that every fixed star hath its own planets, and every planet its own creatures, whose number no man can compute.”
Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 163
Superb thank you
My ten year old loves these videos. Thank you so much!
Gotta start em early
Your videos are great and I would like to repost your channel on the platform known as Ganjing World. Of course, I will keep everything exactly as it is available on UAclips. If this sounds interesting to you, please respond to me. Many thanks!
There has to be other planets 🌎 that is the right size , has a moon to give it a rotation, and the right elements to be life bearing 🦑🐙🐙🦞👽👽 but we will never really know , because they are way too far away to even see properly 🙄
Alien life is inter-dimensional and omnipresent; we can communicate and interact with these beings through our dreams and transcendental states of mind.
Ugh idk about that man. Need more verifiable evidence for this. Not saying it’s false- just not ready to assume yet
Thank You. ❤
man i've been waiting for this.. add eng cc if you have a script
Well. That was a fanciful piece of imagination and some good CGI. Why was there no sound?
Space is our home.🌎
Making a life-bearing planet is - ethically assessed - far more a matter of rare circumstances and considerable bad luck.
Where there is fire, there is also water in its form.
You have to be a bit careful when characterizing our solar system in terms of the first exoplanets discovered, as there is a huge observational bias toward the detection of 'hot Jupiters' (indeed, those were the only kind we could detect in the mid 90's).
@Book Lover that has nothing to do with the most common way to detect exoplanets. People spent a long time knowing things fall towards the earth, took a while to get an equation that utilizes that knowledge. Your comment has zero point. We all know exo planets can be detected with more than one method, I even call it primitive for a reason.
@Big Funny Actually folks, I believe that the first exoplanet discoveries were made using proper motion measurements.
@Tristan J. Cumpole I think it's pretty simple to tell where the axis is. For primitive searching like how we currently do it, a civilization with our technology would likely just look past our system. For the majority of the galaxy they would never receive the blip of lowering light indicating planets in the system passing in front of the star right? But if you looked close enough at earth you could probably deduce an atmosphere fit for life and liquid water. Even if they looked at earth from a distance before there were signs of humans at all.
@Big Funny Depending on their own perspective of course unless you're wondering if the void of Sag A* is peering back at us as payback for peering into it? ;-) I'm not 100% on our current understanding of whether we can deduce the general axis of any given solar system based on our type of observations. I'd imagine that we're probably most of the way through that stage of being able to define this characteristic, or at least most of the way through knowing whether we _can_ deduce it. Do you know how unique the axis of our system is compared to others around the galaxy, ie. is it another defining unique characteristic, or are we just ordinary. So so ordinary?
@Tristan J. Cumpole I can tell you this, our stars north pole points roughly towards the center of the galaxy, meaning anyone out there looking at our star wouldn't be able to use the method of detecting planets when they pass in front of the star. You can also deduce this by the simple fact the milky way in the night sky runs roughly north to south in a band. We're on our side compared to the rest of the galaxy y'know?
I always feel home sick when I watch videos about space.
Im still searching for terrestrial intelligence.✌😝
Pretty cool video but I'm not exactly going to pack my bags!
This video is trippy and awesome, and I get it, I dont matter
I would believe the Guardian of the Galaxy is based on the true story but they just havent swing by to say hi yet 😅
Just imagine landing a rover on another earth like planet. Two things. The photos and videos upon entering would it be buildings or structures or uninhabited with wildlife we've never seen like just imagine.
It's exactly like with love. The first time it's exciting. Once you are on your third marriage it becomes a bit of a downer. ;-)
Sun is not green like I said before 💫🌱
Love of Astronomy is a universal language I find! And bonds people of the World! It bonds people of the world! This Love has no borders! No political issues! No religious!! Instead extending your knowledge of Space, physics, and understanding! A handshake of people's of the World! Mike Johannesburg South Africa!!
Wonder what if anything like aquarius star system is like
There's a channel named ENR that posts all your videos over and over. They posted a video four hours ago titled "How can the Universe be infinite? Is there anything beyond the Universe?". Both videos are yours.
They have three hundred thousand subscribers somehow. They mutilate your videos with added loud music, video cuts, and zoomed-in frames. They delete my comments or banned me, I don't know, when I tell the people commenting to watch them here for the whole video in high definition and with no music and cuts. There's no spot for me to report their channel for copyright somehow. You should put an end to that. They have one-third as many viewers and have to do none of the work. In addition, destroy your great videos to beat the copyright algorithm.
God made his final decision where he want life to be at Earth 🌎.
How do we know nothing is living in these planets?
