Life in the Universe #1: Just on Earth, or Everywhere?
Ғылым және технология
This is the first episode of a series on life in the universe. Looking for life in the universe isn't like looking for your car keys. It's hard to know where to even start. The best place to start is probably by NOT trying to find alien civilizations, but rather ANY kind of life we can.
The problem is, civilizations live and die in the blink of an eye compared to the lifecycles stars. They could come and go and we'd never know it.

Here we are just 7 years later (2013). The Kepler and Wise telescope missions are over. What have we learned in 7 years? More than we knew for the past 1000 years. Planets are everywhere including Free Floating planets. Kepler discovered that in the field of stars studied there were Earth sized planets around every 5th star. The possibility of intelligent humanoid life just like ours or beyond has gone up dramaticly. When the James Web telescope is launched in 2018 we will be able to analize the atmospheric gasses of these Earth like planets and we may find Human Inhabitable planets everywhere. WOW!

in our milky way galaxy alone there are 8.8 billion stars that have earth sized planets orbiting them in the goldilocks zone..that's pretty impressive...is there life on other planets?, I have no doubt about it

Tina Yuzilaitis Congratulations! You have discovered 8.8 billion (minus a few) more earth sized planets in their star's goldilock zones than the scientists have - indeed, that's very impressive!

Tina Yuzilaitis Well, if that article is correct, presumeably it is, then these scientistst are really flipping out with their computer models, in specific as to planets in the goldillock zone. You know, computer models start with a large number of assumed parameters - if you change only one, the whole outcome becomes different. Personally I don't give a hoot for these kind of models - mathematical games, with no physical content. Nonetheless, I agree with you that there must be life on other planets in the galaxy, but what kind of and how abundant or not, remains anyone's guess. The entropy principle however says that wherever the conditions for it exist, life will inevitably arise.
I'm absolutely certain that life is everywhere.

Dublin Of course, I believe the same. I'm almost certain that there is life in Enceladus and Europa since it is thought that they have underground oceans. I didn't understand what Javeed Khan was saying though about life under the sea.
Wow, just came here after seeing a new one (Episode 4) was posted up! I haven't watched it yet but I can already tell that you've come a long way since this! This was still an awesome video and asked all the right basic questions with visuals that were stunning at the time! Can't wait till I watch #4 to see your lovely HD visuals! Great job as always Mr. Darnell!!!
Another great video, Tony, to add to my list of all-time favorites. You got it JUST RIGHT...words, video, music, concept. Love it!
Thank you sir, for putting this together and posting it so that I and others can see it. excellent video!
Your narration is awesome. Such soothing tone to go with the beautiful images.
@fenhen That's right, it's been a while since I made this one, and since that time Kepler has been launched and there's indications of a planet around Gliese 581 that might bear out to have a habitable planet. There's a Kepler vid and a Gliese vid also on my channel.
most beautiful video ever created in this universe. speaks to the core of my soul whenever watched. I enjoy ever second of it.
You're Sooo right.And thats very interesting info you're providing us with. Thanks!
Mr. Darnell, You have a great sense of explaining everything so clearly. Thank you so much...
very compelling argument there, arif. i love how it's backed up with so much evidence. nice work..
great documentary, many thanks for sharing.
I love your videos. Well written and narrated.
You have posted this as a farce. I see the inherent humour and have chortled away! Bravo!
Definitely, and 100 years from now ...when those among and not yet among us are citizens of mars upon a viewing of this (by that time) nearly obscure video will marvel and take a deep breath reveling in how far they came and how much further ...we still have to go.
Wow, great video, very professional and the way you explain things makes what seems so hard to understand more understandable to common folk like me! You could easily make your own TV show, i would watch it.
The cool thing about the universe is that it has no "plan" but, instead, creates, evolves, changes and goes on as it does without a purpose or plan and, so, it's near infinite in its permutations. Beautiful....
I saw it in 2022 first time....15 years later wow...just love it man
This video is almost three years old, but is still relevant scientifically. That's an achievement.
Awesome video =) I can't help feeling very lonely and scared every time I think of space or watch videos with information of space, seems so big and scary
Fan of many years, Tony. Never missed a "keep looking up" video but then you got to technical on me, visiting scientists talking about issues I couldn't research fast enough. I LOVE these, share w/ my kids & grandkids. What is your opinion now about search for life?

Thanks for hanging in there. Keep in mind, I still post Space Fan News, Your Sky Tonight and the short space docs so keep a lookout for those. If you sign up for notifications on deepastronomy.space you'll get an email everytime something is added to the channel. Works way better than KZread notifications which is very inconsistent.
This video is amazaing! :D
Love these videos...oh and the spider is under the 4th chair from the right on the 6th row from the left.
What you just said really helped me, and I can't explain how. Thanks
Excellent video! Music is good too!
Beautiful..
I'd LOVE the idea of us finding aliens on other planets. We've already found small life on the Moon, Mars, and one of Saturn's moons. If life is in our own solar system, then I'm sure there's a lot more in our universe.
Good observation, and you're right, Kepler can't see planets that don't eclipse the star within out line of sight. Even so, there are 300 billion stars in the galaxy to look at, with up to maybe 90 billion that have earth-like planets, even if only a tiny percentage are aligned properly for us to see, we should still see plenty.
This is probably the best youtube video whit scientific content, and news conserning Life in the Universe.
Wow! You're a charmer!
very interesting! Pier, grazie per la condivisione.
I like your optimism!
Didn't Kepler break down? I know it collected a lot of data but any guess now on the James Webb Space Telescope? Please get that one up there before I check out myself!
Dear tdarnell, this is one of your greatest videos; would it be possible to link us with the music you used in this clip so that I may locate and possibly purchase the songs that these snippets are taken from? Thank You!
Hey tom I always loved outerspace since I was a kid and was aiming to be an astronomer, sadly things didnt go as I wished. What I want to ask you is if you know any books for beginners and sky observers that can be helpful to me to start this as a prime hobby please list some. Thanks and keep up the great videos :D.
That's exactly right! Planets have never, or rarely, been discovered because they're so tiny it's absolutely impossible to see them from earth by even the most advanced technology available. That's why we have to do a workaround, for example see how much it dims the light of the star. It's like finding out about your huge island in the middle of the atlantic now because you did a seismic reading on the continents all around it, and thus know it's there, but can't see it.
powerful video :)
We really need an updated version! I almost forgot what 240 looked like.
great video.
about the Kepler telescope and the search method to find new exoplanets: Can kepler also detect exoplanets in solarsystems that rotate at a 90 degree angle to the line-of-sight ? (meaning kepler would look at the north or southpole of the targetted star.) I have my doubts. if not then the detectionrate of kepler is rather low. It only detects exoplanets in case of watching in more or less the same rotational plane as the target solar systems... or am i missing something here?
10 Years on and not yet discovered it, But lets hope for the best that the james web telescope is better than we expected

this deserves a more in-depth video.. on like say a DVD youtube is not good enough ends way too quickly... LOVE it.
I am a fan of Mr. Darnell. He always explain in a simple language that everybody can understand. He also choses the best music in his videos but what really makes his videos unique is his magical amd mesmerizing voice. Please introduce yourself in one of your videos. Thanks for your contribution to science. Omar Khan
remarkable...........something to discuss with your family!
The term "intelligent" has a scientifically specific meaning and is not used as you would in everyday conversation. Usually it's used in the context of life that has a cultural focus, technology, can communicate over large distances, etc. But even life that can move quickly, work in teams, acts in conscious concert with other life forms would suffice. The key is finding the bio-markers and what would constitute evidence (coded electromagnetic signals, etc.).
where can i find the song from start of this video ? i love it :(
thank you very much.
beautiful
Does anyone know the song which starts at 3:15 and from where I can purchase it please?
what's the song playing at the end of this video?
Can you please post the names of the songs used so that those interested may search for them and buy them if they would like? Thanks for a great vid!
you are a clever astronomer tdarnell you upload very intrestning videos but could u pls post a video to explain how the new nasa's telesope works which can see the past cause it is hard for me to understand
gregh Cudos to you man. U R the only one so far to know about my user name. That was great. I guarantee 99% of everyone else here has no idea. I'm impressed.
what is the tittle of the song played in the opening in show
@Raymasaki Oh my ??? Where to begin? Do you have any understanding of the scientific method at all?
someone plz answer me, if the present universe is from a bigbang then it must have boundary (though it is expanding)...then what is beyond this universe( otherwise if our universe is an expanding balloon then what lies beyond it?)
what's the music in the beginning?
@Gapfruit The 'smallest part of life' is a self-catalysing molecule of RNA; complex cells with nuclei (eukaryotes) didn't evolve until about 2 billion years after the first life, and still constitute a minority of lifeforms; most modern organisms are bacteria and archaea, which have cells that lack membrane-bound internal structures and are considerably less complex than eukaryotic cells.
@Dominic4n No. Well, there are planets as big as (or bigger than) our Sun, and there are stars as small as Jupiter (or smaller, if possible). Even so, a star is so dense that it has an extreme amount of gravity, so it would be ALMOST impossible. Take Gliese-581 for example. Its planets are way bigger than itself. Though said, there are some cases wherein a star and a planet orbit each other, but in a case like that... life cannot be supported.
Things which we once thought were prohibitive to life ( extreme heat or cold, extreme pressure, no oxygen, ) have proven to be no barrier to it.
Anyone know the last song in this video? I'd like to know.
What is the name of Song. Its the same song in LOTR war in the north. Im searching for it.
Can anybody tell me what are the songs in this video? Thanks!
It's very clear that we were very close to vacuum (i.e. nothing) than the other side which is some what interesting and curious.
Watching from 25 December 2025. I wish this video can be re-upload with higher quality. Maybe 720 or at least 480.
Among adult humans, the appendix is now thought to be involved primarily in immune functions. Lymphoid tissue begins to accumulate in the appendix shortly after birth and reaches a peak between the second and third decades of life, decreasing rapidly thereafter and practically disappearing after the age of 60. During the early years of development, however, the appendix has been shown to function as a lymphoid organ.
And yes! I do see the irony in my role as a death metal drummer in a band called Harm. God bless :)
How many episodes are there?
Question are there any stars small enough to Orbit around a PLANET instead of the planet orbiting the Star?
Question:If we can't even go to planets in our Solar System and bring back soil samples to earth, how is discovering more planets with samples we can't bring back help us?
"Collective intelligence" can be smarter than an individual but it can stifle an individual's expression too. It's a mixed bag, depending on the task or circumstances. Usually brainstorming among groups yields a better result than an individual can achieve, but not always.
I'm 30 years old and one of my longest wishes is that by the time I die we can detect microbial life in the universe. This will mean that life is abundant and existing.
any1 know the name of the Last song in this video?
It's just a matter of time before we find life elsewhere in the universe. I just hope I live to see it.
does anyone know the song &artist at the start of the video (0:00-0:30) ?????
what documentary was this?
Thanks for this video - I found it interesting/ I am puzzled, though, by your use of the word "civilization" to describe the Egyptians, Romans, etc.. which I think in this context of human survival itself, are more aptly called "empires." That is, though these empires fell, civilization continued, though not with the same political/cultural/etc.. structure. Are you implicitly arguing nuclear weapons (or something else) could cause civilization's end a future empire's fall? I wouldn't argue.
damn where do these universe videos get there music? its never a disappointment
i am talking about size not time, but you are totally right, about the time factor.
@Peter5930 in school they tought us about the 5 characteristics of life by definition. some of them were excitability, growth and the ability to propagate. i don't know whether there is a new definition of "life" in biological meaning, but do these things fit to these self-catalysting molecules of RNA?
Whats the song in the beginning? D:
@shcoome I'm there with you man. It really fascinates me knowing that our little Milky Way Galaxy is just a small part of the universe. I can't wait until we can explore more out there :D
The only theory that could get us anywhere in space, would be the wormhole theory, and that would be an almost instantaneous way to get anywhere
thx for giving me a life on earth
whats the song in the begining?
awesome video does anybody know the name of the songs in this video?
For some reason this guy's voice makes me want to fall asleep.
Please post the names music tracks for this great video! I, and many others I'm sure, will be very grateful!
what is the name of background track anyone pls??
Planets atmospheres always give them away. I have a hunch that our first discovery of life will be analyzing the atmosphere of the planet in question. Our atmosphere is the way it is because of life,and so should the planets we will be looking at.
@tcgreen11 What are you talking about!? My point was that exoplanets are discovered all the time and it's a rapidly moving science. I was basically just informing anyone watching the video about how the number quoted was a bit out of date. I made no reference to the probability of finding life, or the probability of life forming or any such things. In any case the vast majority of planets discovered are not suitable for life as we know it (they're hot and gaseous).
@TheDexter2100 @Isuruke @bibrinka @bibrinka did a little searching on the internet and found that this opening music. Its part of a stockmusic collection: Spirit Legends - "Welsh Piano and Female Vocals". album is like $100 (usd), and it's very hard to come by.
@Morriusvids Can i ask you a question? First, are you afraid to die?
first song name "Angelical Dream"
Johannes Kepler would be proud if he only knew his name carried on in the exploration of space. Imagine his marvel at how the technology and awareness has changed since his time.
Nice vid, anyone know any of the names of the songs?
right on!
I agree with everything you said exept the last part of your first sentance. I have been thinking about intelligence in super organisms and some of the ones I can think of fulfills atleast one of the criteria for intelligence. We think about ourselves as intelligent but is a city intelligent in any way? It is a product of what we think about as intelligence but it resembles an anthill. "Is a collective intelligence intelligent and is it smarter than an individual?" would be a better question.
Whaddyamean?!!! Just confirmin' the possible existence of life in outer space, i found this very thrillin' to know we are not alone and hopefully these other planets are inhabited by friendly forms of life, like Dr. Spock of Star Trek.
Zeitgeist, The Movie - Remastered / Final Edition....lol i cant link it...but its found in parts on YT or in full on google vid
