Thanks for watching everyone and thanks to Ground News for sponsoring this video. Head over to ground.news/coolworlds to give it a try for yourself and get some transparency with where your news is coming from. So do you feel optimistic/pessimistic that JWST could detect biosignatures? How important do you think this question should be for NASA/ESA/JAXA/etc?
I'm still optimistic that bio signatures can be detected if they're out there , but I guess it is unlikely they'll be confirmed with JWST, with so many transits being necessary. Still we can learn from whatever the results are. I would consider bio/technical signatures to be very important and I hope the space agencies do as well. Thanks for the videos!! I thoroughly enjoy them all!
I think that everyone should focus on technosignatures or something that indicates inteligent life. There is so much more options to look at. More possibilities. I know that probability get lower,but we have to look for something we don't know rather than things we know and can be everywhere .
@Random Guy how will you make a "contact" with simple life? It doesn't give us anything. More interesting for me is, if advanced life can survive for longer or even make interstellar trips.13bln years is enought, to breed more such a "species"like us.Even if we find some kind of life on Mars, what does it changes? Copernicus principle is still in tact.Simple life can be everywhere. The biggest problem with our egzistation is, if we can actually move through the cosmos.If not, what's the point of looking?
Based on what you said, no. An Earthlike planet around a white dwarf supporting life must be as rare as Larry Niven's "smoke ring", a gas torus, a ring of air around a neutron star where life exists. Maybe we should look for a smoke ring instead? 😉
I agree! It's always a joy, in a world of Trumps and Putins, with their vulgar narcissism and sheer, selfish contempt for the rest of the world, to be reassured by the humanity and intelligence of intrepid people like David Kipping, and the science that they advance.
We are all just curious humans looking to admire the beauty of the world we live in, it’s easy to forget how rare and beautiful it truly is, that we exist- and that’s why we study Astronomy, astrophysics, astrobiology, astrochemistry etc… we want to share its beauty :) anybody in science would love to explain anything you ask them about their field, just ask, and ANYONE can do this, If you desire to, I highly recommend it :D
We have encountered technological challenges for our entire history that many believed were insurmountable, only to eventually advance through the challenge and unlock the technology. Since we can't know right now, it's most useful to just proceed ahead and assume we can detect life and traverse the stars to meet it. There is insufficient evidence to conclude otherwise and accept the defeat of our dreams.
I think you described that extremely well.... I think to just add on something else to keep in mind is how much the crazy universe has been able to show us things we couldn't have ever even dreamt of and yet "mother nature" can teach us things beyond our wildest dreams, or knock us down a few pegs if needed and not even break a sweat! 💦 🤯 But also gave us tacos 🌮, so I think we should listen and pay attention! ❤️🤗👍
Agree. I like the optimism. And honestly, I don’t even mind if I never live to see aliens, but if jwst helps future generations find aliens sooner I’m completely happy with that.

I must admit that I misunderstood JWST's ability to detect bio signatures, pretty much due to excitement as well as ignorance. Thank you for the thorough explanation of what is actually possible and realistic. Stay curious!
I think JWST just isn't large enough of a telescope to be able to do this reliably. It can in theory but space is just so vast that it's more likely that ill win the lottery in my lifetime than discover life around another world.
@@nh41 I don't even think the Louvoir telescope in development would be able to detect life around another world. The telescope needs to be many many times larger than even the 15 meter design.
This is by far the best atronomy channel on UA-cam. I love space but most channels just cover the same old basic stuff with clickbait titles and thumbnails. You are honest about all your data and calculations and honest when something is nearly impossible but still give hope that it could happen. You also are just a really great video editor (or have a good editor) and make the content emotionally engaging (which is better than the average movie these days sadly). Keep up the great work!
Is a great channel. So many other none sensical hyperbolic garbage channels. So glad to have Dr Kipling. Event horizon is also great. As well as Sean carrol channel
Nothing like a new Cool World's video! I just love how he mixes scientific information with the philosophic ramifications to make it truly thought provoking.
Absolutely. Astronomy is a mix of science and philosophy. And it is kind of funny, we do have a good understanding of how the universe works and yet we don't. There is so much we do not know and probably never will. But it is nice to use common sense.
Don't know if its just me, but every time I watch a new video from Professor Kipping, I get very emotional. I don't know if its the way he explains it, his voice, the material he covers, or just that I am really into what he is talking about. This video made me choke up and I had to wipe my eyes. I think any time talk of life and the survival of life on earth is brought up it hits a cord with me. The shear crazy fact that the Earth and all life on it even exists at all in a Universe that more and more seems to be hostile to said life really is a "Fools Hope" indeed. We are Star Stuff, the Universe trying to understand itself....
As the Professor has stated.. We have been here for less than 1% of 1% of Earths history. What have we done in our short time here.. We red flagged ourselves as being an evolutionary dead end. Endless wars and destruction of the nature that created us. We will have to evolve or go extinct. The latter is most probable.
You have no idea how much I appreciate and enjoy watching your videos. I love the passion for exploring subjects that are on the edge of science and yet a balanced approach to examining them. I will continue to stay curious! Keep going!

Please slow down your speech just a bit as I hang tight to everything you say. I have lived for many years and hang onto life as long as I am able to learn something new about the cosmos. That has always been my reason for living. Your mind and gift for sharing your knowledge and visions is nothing short of astounding. I try very hard to remember and concentrate on everything you say. Many years ago I incurred a serious head injury in the service. I’m proud to be a disabled NAVY Seal and my love in life now is the very thing you talk about. Thank you for illuminating my cosmos!
So what you’re saying is we need to make 100 more James Webb space telescopes, with a lot being specially geared towards exoplanet studies, and then put them in a lot of different orbits. Solid, let’s do it.
“It’s possible.” Wow man, I came to watch an interesting space video and instead I got a much needed pick up while wading through a dark part of my life. Thanks for that.

What we really need are telescopes (space and ground-based, maybe even moon-based) that ARE specifically designed to detect atmospheric bio-signatures, in much the same way Keplar was designed to detect exoplanet transits. I'd also love to see a video from you discussing what it would actually take to send a direct mission to our closest neighboring star, Proxima Centari, and if it could be done within our lifetimes with plausible technology.

Regardless of whether it detects extraterrestrial life or not, the JWST is so exciting to me. Even if it isn’t life, it’s going to make so many amazing discoveries and teach us so many amazing things. I’m following JWST’s journey religiously.
one day it may see a jar within held jabbar who came from afar he plays a Guitar from a planet of tar and brought a bar that had a great scar and within held a tiny brite star
Yea? like what? They promised since the 90's that it would be able to detect life on other planets if there was life to be found. Thats what they've been saying for decades... but they lied. it's just another expensive telescope. And I for one... feel conned.
I absolutely love your videos. I honestly don't know how you stay motivated to keep on doing the research you do given the unlikeliness of it bearing fruit, but I'm glad you do!
I like the purely data driven approach of Prof Kipping. I also like more speculative approaches of other presenters. It's awesome that the search for life beyond earth is really getting a lot of popular interest again!
I've read that technosignatures might be more easily detected than biosignatures and obviously, be more of a slam dunk detection of life. Would JWST be useful in detecting them?
I was doing work (volunteer) for the planetarium in Philly, I asked the smartie pants guys there if we were alone in the universe. Their answer blew me away because it is the truth. They explained to me there are as many synaptic nerve endings in the human brain as stars in the known universe. Quite simply we are the miracle we are looking, waiting to discover. Great video as always my friend
Don't thank us for watching, let us thank YOU and the whole CWL team for your amazing productions. I'm an English volunteer frontline medic, heading back out again to Ukraine, and I REALLY look forward to the rare times when I can chill out and watch your videos - gives me a chance to relax and forget about the shitstorm I'm in. Hopefully, when its all over, I can continue my passion for astrophysics - until then, I'll stay curious. Again, thank you for your videos - they give me hope for a brighter future. Слава Україні.
Another thought provoking video that makes me so happy to have found the Cool Worlds channel. These biosignatures are based on Earth-based biology, not necessarily how other forms of life may work in conditions different to ours (different temperatures, UV and gravity values for example). Do we know of and can look for any hypothetical biosignatures for other kinds of biology?
@CoolWorldsLab (sorry for off-topic but it could make your gravitational telescope idea closer to be realized) It just came to my mind how we could avoid the waste of deceleration in space. Bring a lot of probes, use them as propellant by shooting them the opposite direction you want to accelerate. Use: say we want to plant a lot of mini probes that stay in place at the gravitational focal point of the Sun 1000's of AUs away. 1) the probes will be shot backwards at the current speed of the spaceship so they will stay relative to Sun 2) our spaceship gets extra speed going towards another star 3) when we arrive at the target system we may want to shoot the remaining probes at much higher speeds away so we slow down and the probes can continue their journey at a much higher speed. Result: much less fuel is wasted on acceleration phases
Really fantastic video cutting through a lot of the hype/clickbaity kind of information out there about this potential within JWST or more specifically radio astronomy in general, thanks a ton.
Oldest rocks on Earth - possibly 4.2 billions old - contain hematite (rusted iron in water). So 4.2 billion years ago there was enough EXCESS oxygen to rust dissolved iron in the oceans (that's a lot of excess oxygen). This indicates that photosynthetic organisms already flourished on Earth possibly as early as 4.2 billion years ago. The first cyanobacterial mats were fossilized in 3.7 billion old rocks which implies existence of multiple organisms already existing on Earth.
Your videos are a gift to the world. What a pleasure to watch and learn. Thank you wonderful human being for sacrificing your precious time for the sake of the rest of us.
As expected from Dr. Kipping and all the team, yet another great thought provoking video. His last comments mean I'm going to bed happy but with thoughts that will keep me awake for hours. 😊🥰😊
The fact that we’ve discovered exoplanets is itself incredibly fascinating. Whole planets with a rich history of movement of material (perhaps land water etc.). History similar to our own geological past.
"... the pinnacle of our engineering ..." Absolutely right. Now that we know it can be done, such extreme work will be used again on many other projects. Research, it's called, research. Always pays off.
such an informative and simultaneously beautiful video, thank you so much. i also loved gandalf at the end about “a fool’s hope”… but of course that fools hope eventually panned out in LOTR, i hope we share the same fate in our search for alien life!!!
If he was in a podcast with Brian Cox it would be so good to just listen too. Hearing to soothing voices talking about nature and space would be top teir
I'm glad that you mention that not all life forms could be carbon based like ours. Theres the possiblity of slilicon along with others that we are only aware of so far
The JWST revitalized my interest in astronomy, that was lacking for many years. I'm again excited about the whole thing. It is worth every (how many?) cent! :)
I thought that finding aliens was one of JWST's coolest projects if not the whole point. Oh dear. Trappist sounds like an icy, radiation-seared hellhole. I'd not be spending too much time on it.
Thanks Mr. Kipping PS seen an interview recently where you said alien "life" could be an organism covering a planet...or something like that (I was tired but it was neat much like this video. Thanks for your hard work always, stay blessed
Your comment about an entirely new planet forming around the white dwarf seems so doable as all the elements could be present after the old star exploded. Brilliant idea!
This vid is beautiful and has so much re-listening value! HOWEVER, the importance of a moon or near oscillating gravitational object affecting a planet showing a BioSig in our definition of a habitable zone cannot be understated for the existence of an environment that might sustain life for an extended period of time. Where does your work on exo-moons fit into the process once a potential BioSig is recognised? Jeez, that was a long winded question…
With Limbach's method at the end, it's absolutely essential. Because that method cannot resolve a planet versus a planet+moon, so you might well be detecting methane on the moon and oxygen on the planet. In that case, there's actually no need for life. So knowing if there's a moon there is central, yes. Damn I should have pitched our own research there!!
@@CoolWorldsLab Well then, that's your follow up vid and one I am sure we all will look forward to! Seriously tho. Your stuff is up there with Sagan. Do not stop making these!
Great episode Dr. Kipping. Good luck on JWST time. Maybe you should be part of the scheduling committee. But, I guess that would mean you couldn't get anytime for your cool worlds projects. Moons?
The end of this video brought a smile to my face from ear to ear. "It's possible". A side-thought: assuming the Earth is a "standard" for life-carrying planets (perhaps a big assumption, but we have to start somewhere), then why not focus on G-type stars like the Sun? Is it harder to detect (earth-like) planets around a G-type star than around white dwarfs?
Beatiful video! full of hope and rigorous data!!! In my perspective.. the problem of finding proof of life with a sigma-5 level, Its a quantitative problem.. its not "how", its "when". Imagine if we couild place one or two more JWST-like telescopes in complementary sides of the same L2 orbit.. that way we could focus 3 times the time in trappist-1. Or imagine if we could only fine a nearby candidate outside of the orbital plane of our solar system. We need more telescopes. Whatever the case, i thing we could find life within the decade.
I would go as far as to say that life spawns with all types of stars, hell even around planets that provide tidal heating or maybe even around black holes. There's probably millions, if not hundreds of millions or even billions of life inhabited planets. But, in a universe of over one quadrillion stars, it's an inconceivably small fraction.
I was like you once, grounded by scientific method and reasoning, a pragmatist, but after a very real encounter with a UFO I now know we are not alone, so while addressing the concept of theoretical life out in the Cosmos you seem somewhat oblivious to the multiple reports of advanced craft that exhibit no Human technological traits whatsoever, they can’t all be light from Venus refracted off swamp gas. As science lessons go you nailed it, as far as the question of detecting Alien life, not so much. I sincerely hope you have an encounter of your own, life affirming would be an understatement.
The flaw I see with life around White Dwarves is if life were possible there it should be absolutely anywhere in the Universe warm enough for liquid water. I guess that's possible, but the broader the path to life the more our existence becomes paradoxical. My feeling these days is the type of star, metallicity of the star and it's system are probably critical to allow possibility of abiogenesis.... On the other hand maybe the Crab People of Sirius B are debating the possibility of life around G type stars right now 🤔

Regardless of whether it detects extraterrestrial life or not, the JWST is so exciting to me. Even if it isn’t life, it’s going to make so many amazing discoveries and teach us so many amazing things. I’m following JWST’s journey religiously.
one day it may see a jar within held jabbar who came from afar he plays a Guitar from a planet of tar and brought a bar that had a great scar and within held a tiny brite star
Yea? like what? They promised since the 90's that it would be able to detect life on other planets if there was life to be found. Thats what they've been saying for decades... but they lied. it's just another expensive telescope. And I for one... feel conned.
@@alberteendean4077 conned out of what?
tax money? let's be honest the government was gonna take it anyway regardless of what it is used for
I’m obsessed with his videos simply on how well he says “JWST” as only four syllables. How the hell does he roll that off the tongue so well!?
I could listen to this chap read anything. Awesome narration voice.
it is a College Lecture voice
Thanks for another amazing video David. As always, I'm reminded of just how astoundingly lucky we are to have been gifted with life.
Your ability to convey narrative and emotionality inspires those of us who understand the world through stories.
I absolutely love your videos. I honestly don't know how you stay motivated to keep on doing the research you do given the unlikeliness of it bearing fruit, but I'm glad you do!
Getting paid to search for aliens seems like a pretty dope job lol 😆
I like the purely data driven approach of Prof Kipping. I also like more speculative approaches of other presenters. It's awesome that the search for life beyond earth is really getting a lot of popular interest again!
God the beauty of your work. Thank you so much. The love and heart put into your pieces are mind-blowing. Thank you. 🙏
Nice job on the Lex Friedman podcast. Hope to see you guys together again in the future!
I just caught that earlier! Great stuff for sure!
Love watching your vids in the dark at night, it hits different
That's how I imagine folks watching them...
David the way you convey a story is is amazing , thanks for sharing.
Once you saw Cool Worlds’ talk with Lex, you finally understand that this channel is well-grounded on facts and beauty
I've read that technosignatures might be more easily detected than biosignatures and obviously, be more of a slam dunk detection of life. Would JWST be useful in detecting them?
I was doing work (volunteer) for the planetarium in Philly, I asked the smartie pants guys there if we were alone in the universe. Their answer blew me away because it is the truth. They explained to me there are as many synaptic nerve endings in the human brain as stars in the known universe. Quite simply we are the miracle we are looking, waiting to discover. Great video as always my friend
What a beautiful comment, thank you for sharing 😊
So glad I recently found this channel. I’ve binged your videos and it’s so good!
Don't thank us for watching, let us thank YOU and the whole CWL team for your amazing productions. I'm an English volunteer frontline medic, heading back out again to Ukraine, and I REALLY look forward to the rare times when I can chill out and watch your videos - gives me a chance to relax and forget about the shitstorm I'm in. Hopefully, when its all over, I can continue my passion for astrophysics - until then, I'll stay curious. Again, thank you for your videos - they give me hope for a brighter future. Слава Україні.
Another thought provoking video that makes me so happy to have found the Cool Worlds channel.
These biosignatures are based on Earth-based biology, not necessarily how other forms of life may work in conditions different to ours (different temperatures, UV and gravity values for example). Do we know of and can look for any hypothetical biosignatures for other kinds of biology?
I watch these videos with my daughter and we absolutely love them . We learn a ton and really really enjoy them , great work!
It is good to hear you be optimistic again. Keep finding those optimistic moments!!
Gives me hope there is actual people making videos like these actually diving deep into the cosmos and giving it away for free ❤️
@CoolWorldsLab (sorry for off-topic but it could make your gravitational telescope idea closer to be realized)
It just came to my mind how we could avoid the waste of deceleration in space.
Bring a lot of probes, use them as propellant by shooting them the opposite direction you want to accelerate.
Use: say we want to plant a lot of mini probes that stay in place at the gravitational focal point of the Sun 1000's of AUs away.
1) the probes will be shot backwards at the current speed of the spaceship so they will stay relative to Sun
2) our spaceship gets extra speed going towards another star
3) when we arrive at the target system we may want to shoot the remaining probes at much higher speeds away so we slow down and the probes can continue their journey at a much higher speed.
Result: much less fuel is wasted on acceleration phases
Really fantastic video cutting through a lot of the hype/clickbaity kind of information out there about this potential within JWST or more specifically radio astronomy in general, thanks a ton.
Oldest rocks on Earth - possibly 4.2 billions old - contain hematite (rusted iron in water). So 4.2 billion years ago there was enough EXCESS oxygen to rust dissolved iron in the oceans (that's a lot of excess oxygen). This indicates that photosynthetic organisms already flourished on Earth possibly as early as 4.2 billion years ago. The first cyanobacterial mats were fossilized in 3.7 billion old rocks which implies existence of multiple organisms already existing on Earth.
Premortial O2
Thats the stuff that got used up ? Before life makes it
Seriously love these videos! Thankyou yet again for filling me with awe and wonder
Your videos are a gift to the world. What a pleasure to watch and learn. Thank you wonderful human being for sacrificing your precious time for the sake of the rest of us.
Never opened a video this fast
ye pretty much
Ditto
Damn it, I’m out for dinner…. Will have to watch later.
I'll be waiting... ;-)
As expected from Dr. Kipping and all the team, yet another great thought provoking video. His last comments mean I'm going to bed happy but with thoughts that will keep me awake for hours. 😊🥰😊
Great channel. We love ya man
The fact that we’ve discovered exoplanets is itself incredibly fascinating. Whole planets with a rich history of movement of material (perhaps land water etc.). History similar to our own geological past.
Top UA-cam channel. The only notification I have ever turned on. Please discuss in depth the Miller-Urey experiment.
"... the pinnacle of our engineering ..."
Absolutely right. Now that we know it can be done, such extreme work will be used again on many other projects. Research, it's called, research. Always pays off.
such an informative and simultaneously beautiful video, thank you so much. i also loved gandalf at the end about “a fool’s hope”… but of course that fools hope eventually panned out in LOTR, i hope we share the same fate in our search for alien life!!!
If he was in a podcast with Brian Cox it would be so good to just listen too. Hearing to soothing voices talking about nature and space would be top teir
Love your channel bc you always remain factual, provide/explain requisite biases, and don’t hype!
I'm glad that you mention that not all life forms could be carbon based like ours. Theres the possiblity of slilicon along with others that we are only aware of so far
not at all, look at PBS science channel there is explained why
Silicon life isn't at all possible.
The JWST revitalized my interest in astronomy, that was lacking for many years. I'm again excited about the whole thing. It is worth every (how many?) cent! :)
Praying for success of efforts to extend service life of JWST, having understood it's critical role in SETI; thx to ur insights.....hope IT'S POSSIBLE
I’m obsessed with your videos man, thank you! I love pondering about intelligent life in the cosmos.
I thought that finding aliens was one of JWST's coolest projects if not the whole point. Oh dear. Trappist sounds like an icy, radiation-seared hellhole. I'd not be spending too much time on it.
The Gandalf sound bite at the end gave me chills.
It's such a joy to learn new things watching your videos.
Thanks Mr. Kipping PS seen an interview recently where you said alien "life" could be an organism covering a planet...or something like that (I was tired but it was neat much like this video. Thanks for your hard work always, stay blessed
Loved your Interview with Lex! Can't wait for Round 2!
New to this channel. Blown away! Excellent content
Your comment about an entirely new planet forming around the white dwarf seems so doable as all the elements could be present after the old star exploded. Brilliant idea!
This vid is beautiful and has so much re-listening value! HOWEVER, the importance of a moon or near oscillating gravitational object affecting a planet showing a BioSig in our definition of a habitable zone cannot be understated for the existence of an environment that might sustain life for an extended period of time. Where does your work on exo-moons fit into the process once a potential BioSig is recognised? Jeez, that was a long winded question…
With Limbach's method at the end, it's absolutely essential. Because that method cannot resolve a planet versus a planet+moon, so you might well be detecting methane on the moon and oxygen on the planet. In that case, there's actually no need for life. So knowing if there's a moon there is central, yes. Damn I should have pitched our own research there!!
@@CoolWorldsLab Well then, that's your follow up vid and one I am sure we all will look forward to! Seriously tho. Your stuff is up there with Sagan. Do not stop making these!
Excellent Presentation made simple!
Always nice to watch one of your videos at night before going to bed. A pleasant way to prepare for galactic dreams. Thank you.
Thank you for the final part of your video , I needed to hear that
"It's possible!". This channel is so interesting & uplifting. Thank you!
Great episode Dr. Kipping. Good luck on JWST time. Maybe you should be part of the scheduling committee. But, I guess that would mean you couldn't get anytime for your cool worlds projects. Moons?
The end of this video brought a smile to my face from ear to ear. "It's possible".
A side-thought: assuming the Earth is a "standard" for life-carrying planets (perhaps a big assumption, but we have to start somewhere), then why not focus on G-type stars like the Sun? Is it harder to detect (earth-like) planets around a G-type star than around white dwarfs?
Beatiful video! full of hope and rigorous data!!!
In my perspective.. the problem of finding proof of life with a sigma-5 level, Its a quantitative problem.. its not "how", its "when". Imagine if we couild place one or two more JWST-like telescopes in complementary sides of the same L2 orbit.. that way we could focus 3 times the time in trappist-1. Or imagine if we could only fine a nearby candidate outside of the orbital plane of our solar system. We need more telescopes. Whatever the case, i thing we could find life within the decade.
I would go as far as to say that life spawns with all types of stars, hell even around planets that provide tidal heating or maybe even around black holes. There's probably millions, if not hundreds of millions or even billions of life inhabited planets. But, in a universe of over one quadrillion stars, it's an inconceivably small fraction.
The best videos on UA-cam!
I was like you once, grounded by scientific method and reasoning, a pragmatist, but after a very real encounter with a UFO I now know we are not alone, so while addressing the concept of theoretical life out in the Cosmos you seem somewhat oblivious to the multiple reports of advanced craft that exhibit no Human technological traits whatsoever, they can’t all be light from Venus refracted off swamp gas. As science lessons go you nailed it, as far as the question of detecting Alien life, not so much. I sincerely hope you have an encounter of your own, life affirming would be an understatement.
Your interview with Lex was fantastic! Thank for doing it.
The flaw I see with life around White Dwarves is if life were possible there it should be absolutely anywhere in the Universe warm enough for liquid water. I guess that's possible, but the broader the path to life the more our existence becomes paradoxical. My feeling these days is the type of star, metallicity of the star and it's system are probably critical to allow possibility of abiogenesis.... On the other hand maybe the Crab People of Sirius B are debating the possibility of life around G type stars right now 🤔
As with many things cosmic, the greatest enemy against gathering new information is time
Love this channel! I always listen to this channel while I'm at work,
Great video. Keep posting on transmission spectroscopy.
