The people in charge of managing space telescopes are already planning for the follow-up to JWST: The Carl Sagan Observatory. The plan is to design it so it will be able to detect candidate Exo-Earths!
Big thank you to Matt Mountain (STSci, AURA) who recently gave a lecture in Oxford on his experience leading the planning and development of JWST and who touched on the Carl Sagan observatory in his talk.

👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

Yesterday I saw Jupiter's moons through binoculars for the first time in my life. * with my actual eyeballs! * 10/10 would recommend, great feeling of wonder and awe
binoculars are the best
Awesome! That's always exciting and never gets old. Next, try and find Saturn's rings.
I had that a few decades ago. Saturn and Jupiter were both at a "close" position to earth and I was up north at a cottage (not much light pollution) and a friend of mine pulled out his telescope and showed us the two planets (and moons). No photograph can ever do justice to seeing such a thing with your own eyes! I think if someone had showed me this when I was younger I would have caught the astro bug for life.
If your binos are of low zoom, but with high light gathering, and you are on the Northern Hemisphere, you can see the andromeda galaxy. It's huge, over 5 full moons wide. In the Southern Hemi you can see the Magellanic clouds, our satellite galaxies.
@@StockportJambo I did try, it wasn't within my visible horizon.
The series Cosmos was seminal in my journey to science appreciation. It still is. Mr Sagan is sorely missed and to build such a telescope in his honor is beyond awesome.
I could not have said it better. Carl Sagan is a titan in astronomy popularization and appreciation!
I agree 100%. While I had been interested in science for over a decade before the Cosmos series aired on PBS, I was totally absorbed by it. I loved the coincidence that Cosmos talked about a comet colliding with Jupiter and then comet Shoemaker-Levy 9 actually did it over a decade later.
Same here
Same
Even if costs $20B to build the Sagan Observatory, the United States *ALONE* has already wasted *FIVE TIMES* that much money on Ukraine already in the past *EIGHT MONTHS* . Think about that for a moment.
💫🤔🤷♂️🍻
Carl Sagan was the best science educator that I've ever seen. I watched his original Cosmos series back in 1980 and I was spellbound all the way through. He was a great man.
Every science communicator today stands on his shoulders.
They are either his direct acolytes or inspired by one of them.
BTW,
Why aren't gradeschool literature teachers using Pale Blue Dot as a lesson?
Not only a fine piece of literature, but far more relevant to a modern perspective.
Especially in a world where so many factions want to carve this tiny little world into smaller and smaller pieces.
Even though some of it is out of date today the show and more importantly his message to evolution has never been surpassed
I am thrilled that Carl Sagan is being honored by naming this amazing technological beauty after him. This is wonderful. Thank you. 🌻
Agreed. His 'Cosmos' series was what really got me into astronomy and the study of the universe as a hobby.
Incredibly it won't be named after a female black vegan lesbian.
@@LarsRyeJeppesen Troll harder, fascist.
I'm not. Everything we learn from the cosmos glorifies the living Lord God who created it and created us. Old Carl never gave glory to God. He also thought there must be a bunch of life out there. Why should we honor him?
@@KenJackson_US _"Carl never gave glory to God"_
Smart people usually don't. I mean, look at you. You subscribe to creationist and RWNJ channels. That makes you the opposite of smart.
The Carl Sagan Observatory, I absolutely love the name, it's perfect.
I would go as far as to say there should be a segmented mirror telescope pipeline in continual development -- one that can take advantage of new technologies as they are discovered and also foster a community of expertise covering various aspects of segmented telescopes.
Yes! Capitalize on experience instead of one-off projects
@@kylecramer8489 Then there would be people complaining that NASA is playing things too safe and not looking forward.
It is also worth noting that with Starship hopefully coming online shortly here we have the potential to launch more like 8-meter mirror segments. You can get a MASSIVE telescope going with easy and repeatable 100-ton 9-meter diameter launches.
That's what happened to the JWST, it was constantly held up by the engineers replacing the old tech with the new until the next 'thing' came along.
I think we need to utilize more flux capacitors to see back into the future.
Carl Sagan, was an amazing person. Well before his own time, and forever in our memories. I like to think he's out there still, traveling the cosmos, and learning it's secrets.
Start researching near death experiences and you’ll have no doubt he is.
Truely a modern day saintly figure that gave us gifts that will give for generations.
i can't hear carl talk without tearing up. his soul shone brighter than the stars he studied and he loved all mankind like no public figure ever has before or since. i've very much tried to follow his example even though i lack his bottomless well of patience, but it's worth the effort, partly because he thought so.
Hearing the Sagan quote gave me goosebumps. What a legend! I've very looking forward to seeing the observatory take shape.
Same.
I remember being younger never missing an episode of Carl Sagan on TV talking about billions and billions of stars. At the time there was no other show on television I would actually grab your thinking and pull you out into the universe and start to get the concept of so many things that you had never even thought about being taught. It was almost mine blowing. 👍🏻
Actually, that was Roy Scheider, in Jaws. 😆
@@Nerd_of_Anarchy the quote is at 13:00
@@ivoivanov7407 Obviously you're not a golfer
Thank you for paying homage to Carl Sagan. His passing from the earth caused me very real emotional distress, it was a sad day for humanity. He had more impact on my way of thinking than almost anyone. I hope he was comforted in his last moments by knowing he would again become one with the universe he so dearly loved. You will never be forgotten.
you expressed same feeling as of mine but I was 4 yrs old when he passed away and I miss him today also.
He died in the same year that I was born. I watched his Cosmos series first in 2008 and it changed my life---because of Cosmos and his books, I decided to study physics seriously, in the university. I ended up also learning some English in the process, which made it possible for me to write this comment 😛
@@User-jr7vf That's awesome!
Same here. Carl Sagan was and still is my role model and one of my heroes. He was one of a kind and one of the greatest humans to ever live IMO
Billions and billions were saddened by his passing
After watching Cosmos as a kid on TV, Carl Sagan became a hero of mine growing up. And he was a bit of a legend in his own right too. So I’m very happy he’s going to get an upcoming new state of the art space telescope named after him, nobody deserves it better 😁👍
Carl Sagan is the greatest source of inspiration for who I am today, and a massive part of why I'm going to major in astrophysics, the man is a poet who inspired so many, the idea of the next big telescope honoring his name, and possibly bringing it back to the public eye so others may discover him has me beaming like I did when I was 10, watching cosmos with my family with dinner.
I'll never forget seeing Saturn through a 24 inch dobsonian telescope. I was part of the astrophysics club in university, the only language student in the group because math escapes the faculties of my mind, we had the original Cosmos quietly playing in the background for the guys who had scope fatigue.
Seeing the rings made me shiver. Sagan then began narrating on the ship of the imagination going to the stars.
The professor then asked me if I wanted to see something cool. He pointed to alpha centauri and to my eyes it looked like a single star. We pointed the scope and just as Sagan was narrating on the possibility of life on our neighboring stars i saw our two closest stars, like the headlights of a car fron far away.
I never could study astrophysics, but that night with Sagan's narration, i invested myself to become a science and geography teacher, amateur astronomer, and dabbling scifi writer.
Three of my old students went on to study astrophysics.
Wherever Carl is today, I just want to say, Thank You. A tiny thanks, to a great man, from a miniscule pale blue dot floating in a sunbeam.
Sagan changed my life in more ways than one might think. He died in the same year that I was born. I watched his Cosmos series first in 2008 and also read his book The Deamon Haunted World. Because of Sagan work, I decided to study Physics at the University, which in turn made me learn some English. So in a sense I'm typing this text thanks to Sagan. 😛 By the way, many people were influenced by Sagan's works here in my countruy, including now university professors.
Hows the writing going?
I was also "turned on" by a faint image of saturn thru a homemade scope.
I've tried writing.
Insplit the story into 10 parts
Get bogged down about 8th part
@@huepix Writing a fantasy trilogy now, be a few years till it's ready though.
What a great story! Thank you for that. How wonderful that there are three people who might not be astrophysicists today if it wasn't for you (and Carl).
I realize that this is late for you, but if I could talk to that language student you were, I would tell that person that mathematics IS a language, a language of abstractions and logic. It can actually be a bridge of understanding since Hindu-Arabic numerals are internationally used, and so are the mathematical operators. You could see a math book written in a language you don't understand, e.g., Hindustani, Italian, Russian, and even if you don't understand the _text,_ the math notations will show you what the text is trying to say. If we ever encounter extra-terrestrial intelligences, we may at first try to communicate with them with mathematics.
Just wait...in 40 years we will be seeing the Becky Smethurst Space Observatory being put into orbit
... hihi that would be sooo awesome! The "Beckyscope"!
Yes! And it will be a solar gravitational lens telescope that lets us see alien traffic jams…
Not likely. She will be alive and well for the next 60 years at least
It will talk like Sean Connery and be looking through black holes (NOT black, NOT holes! 🤦)
That would great to see. But judging from jwst, it's more likely in 40 years we'll finally see the Carl Sagan observatory launch.
Carl Sagan was an astonishing communicator! And you walk in his footsteps! As a student in Astrophysics you keep reminding me why i started in this field!
No one better than Carl Sagan deserves that honor. His voice resonates in my mind and in my childhood memory. He will forever be all around us and everywhere.
Could not have a more worthy name for the successor.
Sagan was a righteous dude
The Cosmos is not the same without Carl Sagan in it. He was a truly unique scientific educator and an astute intellectual who is sorely missed. FYI Dr. Becky, I just ordered your book and am looking to reading it! 👍👍😉😉
"Contact" was awesome, both book and movie.
Well if we think about it he has never left. His atoms and energy is still here but they have just been returned back to the universe. And when the sun destroys our planet and goes supernova we will become stardust once again to hopefully become another solar system, and hopefully another Sagan will be born of that future solar system as well.
@@drutalero2962 that is a beautiful thought.
Carl Sagans true skill was to not only see and understand the universe, but to truly connect to the profound beauty that it encompasses. This connection allowed him to not only explain ideas with clarity and accuracy but to represent its beauty by wrapping those explanations with poetic beauty as well.
I doubt we will ever see someone embrace this important connection in the way that Carl Sagan did, ever again, and I can live with that.
And a truly unique voice. The earth would be well served if his was the first voice another civilisation heard. (Stephen Fry would be a good second)
When I was a kid I watched the original Cosmos and I've read some of Carl's books which had a great effect on me. His passing affected me greatly and still does. He was one of my heroes. He'd be very proud that such an incredible machine was being named in his honour.
so happy to hear that Carl Sagan will be honored in this way. I watched Cosmos as a teenager with my dad, and loved his novel that was turned into the movie Contact.
Becky, you are by far my favorite person on CZcams. Even though I don't understand half of what you say I hang on your every word. Your Enthusiasm for your profession is captivating. Thank you, don't ever stop putting out content.
Ditto.❤
Couldn't help but get deeply emotional at the thought of the next space telescope being named after my idol. Carl changed and grew my perception of space, and the possibility for life. I'm only 25 now, and I can imagine when I'm 37 when this thing launches, I'll be filled with even stronger emotions. I hope to one day be half as good as Carl, and you Becky.
Your videos give me hope for the future.
I cannot wait to witness.
I hate to be pessimistic as I love all things space but let's be realistic; the Hubble was originally planned to launch in 1979. It didn't launch until 1990. JWST was supposed to launch in 2010. It didn't launch until 2022. As far as space telescopes go, just tack on 10 years from their predicted launch date. So in 22 years it might launch. Maybe.
@@zidbits1528 as long as it’s before I’m dead
Assembling the Carl's version is easier, like JWST, those hexagon mirrors can be *both* rugged & puzzle attached by a spider drone/mech after a web 🕸 shape background frame is first assembled. make those mechs. Before sending.(Plz be more than infared🙏)
It is so touching to see such a nice project to be named after Sagan, someone who certainly got many people of our generation in love with Astronomy. Excellent video, thank you!
A solar gravitational lense telescope would be so incredible. Carl Sagan was one of my childhood heros. He deserves a monument in space erected in his memory. Love this
Why not use Starlink technology to link a constellation of JWST telescopes into one gigantic telescope? We organise a field of radio-dishes into one big dish on earth,. shouldn't we organise thousands of telescopes in space into one gigantic telescope, let say 10000 km in diameter?
@@reasonerenlightened2456 so yes, do that at the L1 Lagrange point between earth and the sun south we shade the earth just a little bit and temporarily reduce the effects of global warming while we work on removing the CO2 causing it.

@@danielschmidt2186 Global Warming is a lie. Evidence: if the Oceans warmed by 1*C thru their depths, the thermal expansion of 3 miles, 5 KM average of water would be 10 feet (3 M) We are observing about two inches (50 MM) since 1980.
Why didn't the predictions of Kyoto Protocol come true by now ?? Because the Scientists were wrong, is why.
@@peterdarr7267 I suppose we shall see. The permafrost is melting and releasing massive amounts of methane. This is a tipping point that will warm the planet much faster than it has been through fossil fuel and agriculture emissions. This decade will see some significant changes and nobody really wants to say "I told you so" but we shall see. I'm optimistic we have all the solutions to withstand the change and ultimately have control over the future of the climate
Carl Sagan deserves to have more incredible things named after him!
Actually, the Mars Pathfinder lander was renamed Carl Sagan Memorial Station in his honour. But, yeah. It would be awesome to have a space telescope named after him.
_Funastrum saganii_ is an asclepiad vine from Veracruz, Mexico.
Wait, do you mean more "incredible things" or "more incredible" things named after him? Cause the most powerful visible spectrum space telescope is about as good as it gets.
Billions and Billions of things should be named after Carl Sagan! Plz nasa
Carl Sagan deserves a Universe...
Good to hear. I agree, the Carl Sagan Observatory is an absolutely perfect name for the next space telescope. Thanks for the video!
Sagan was such an eloquent speaker. He could draw you in and keep you interested with such ease it was uncanny. No doubt the Sagan Observatory will be able to do the same, sparking within us a sense of wonder as he did, not so long ago. I absolutely loved the quote at the end. Yes we should keep looking, because it will, eventually, tell us who we are. Thanks, Dr. Becky! 😍

I wish I had something fancy to say, but I am just a redneck that loves to look up. About to by a telescope for only the second time in my life. Carl Sagan is the one who inspired me to start looking up. His Cosmos series was amazing. I miss him.
I love seeing your book behind you. It’s is an awesome and comprehensive listen that I thoroughly enjoyed. You read it perfectly.
And I probably won’t be around in 12 years but if anything will have me fighting to stay alive it’s the thought of what this telescope will see.
I am so happy the decision has been made the name the next space telescope after the late great Carl Sagan.
He was such a passionate communicator of Astronomy and Astrophysics to us all, I am sure the CSST will deliver fantastic data to the whole of the global astronomical sciences.
To carry the name of Carl Sagan, it’s going to have very big boots to fill, wishing the CSST all the luck in the world. ❤️
Great video Dr. Smethurst! Your book is a great pleasure to read; very easy to understand and a compelling story. Highly recommend it! The dedication of the next space telescope to Carl Sagan couldn't be more appropriate.
Great video! Also, I love your last blooper. It shows me that you are not only incredibly gifted, but funny and connected to life.
I love the way you discuss all those cosmic topics!!! Thank you!!!
Patiently waiting to hear about the Trappist planetary atmosphere results!!! The Sagan Observatory sounds extremely exciting!
a great honor for my favorite astrophysicist. I hope the Sagan craft gains a lot durability upgrades as we learn from JWST
Always a pleasure to hear from somebody with a gifted intelligence. Thx for posting.
This was one of the most informative astronomy videos I have ever watched. So much data. If this was a Brian Cox documentary it would take about twenty years

Agreed !
The word beautiful isn't spoken every 10 seconds like a Brian Cox doc.
@@S-I-T His books are very good though.
This might be the last solo space telescope we‘ll ever launch.
At some point it will be more beneficial to launch an array of scopes not much bigger. Meaningful resolution increase might only be achieved with multiple mirrors at larger distance from each other.
13:03 wow that transition from your voice into Carl's gave me Goosebumps.
I find all space stuff, [ Technical name for Astronomy ] extremely interesting and you explain it so well. Love your vids. Thanks.
I hope this gets the green light. Between the Artemis Program, this CSO, ITER, and the (minor) leaps in quantum computing we're achieving, I can't help but think humanity is on the brink of some truly great discoveries. Brings me some happy thoughts in these otherwise bat-shit crazy times

I’m looking forward to seeing “Billions and Billions” more galaxies from the Carl Sagan space telescope.
Very cool news! A significant complication in developing JWST was the thermal shield to keep the IR sensors cold. Would a visible light telescope need as complicated system or would a single layer sun shield be enough?
I greatly appreciate, Dr. Becky, that you avoid segue advertisement in your videos; saving the sponsors to the end. Thank you, for this video.

Content like this is CZcams at it's best. Thank you kindly for what you're doing. It's much appreciated. I hope to live to see when we can park a macroscope outside the inner planets to see what truly is out there.
It has been my contention that we needed to keep the workforce active in projectects in NASA. It keeps things going, costs down, quality up and hope it is so with this project.
Just as long as Boeing isn't involved!
Thank you, Dr. Sagan.
The carl sagan obervatory is now my favorite telescope of all time, carl sagan is my idol, my hero and one of humanities greatest imo
So it seems the upcoming huge ground-based observatories are really capped by the Earth's atmosphere even with adaptive optics preventing them from doing the same.
Also, if the Carl Sagan observatory is designed to perform in visible light, with cryogenic temperatures unnecessary, maybe the sheer size is the main challenge moving forward.
15:22 This made me feel better as you've shown even maths-loving astrophysicists could get rusty at quick arithmetic. 😅
The need for that heat shield added quite a bit of complexity to the JWST. I also suspect the requirements will not be as stringent for the Sagan observatory, which would take a lot of time off development.
This telescope should be built on the moon, then it can just be a lot, lot bigger.
@@paulmichaelfreedman8334 no it wouldn't, unless most components can be manufactured on the moon.
Building a telescope on the moon would have the added complexity of having to land on the moon with no real benefits attached. At least not for optical telescopes.
The only thing that might make sense would be a radio telescope on the far side of the moon.
No they are not. This proposal is nonsense.

Carl Sagan, could watch him for hours. I best remember him for "The Royal Institute Christmas Lectures" in 1977.
That got me HOOKED
I joined the North Wales Astronomical society. Some of the things that they have worked on
and what i have seen is really out of this world.
Since covid started we have not yet restarted our meetings.
They are truly a fantastic amazing group of people.
I am also an avid fan of yours.
Best wishes. Ron.
One thing with the sagan tho- it has like FOUR times as many hexagons- and we were all nervous about them working right with jwst! Just one of them fails to fold out right and you have no telescope! Imagine having to do it with one with 3-4 times as many panels? Can you expect every one to work flawlessly?
The only advantage might be it being an optical scope. It wont need a heatsheild Or to be out at a lagrange point right- it can just go into earth orbit like hubble? If so- it would be available for fixing and upgrading etc - we'd just need to modify dragon or something to be able to go to it- like they are already proposing with hubble.
I was wondering if it is possible to have a crewed space observatory in a figure 8 orbit around earth-moon. we could add modular scientific instruments (large mirrors taken up in steps) aswell as a successor to the ISS. On the orbit closest to earth it could take supply/crew and around the moon you could also launch lunar missions. Would the interference of lunar/earth light be too much noise for the observatory? (also seems like a good practise to launch crewed flights to mars)
I would guess an 8 orbit around earth and moon is still much too close to both with their disturbing stray light from all sides and in addition too complicated an orbit that would need too many corrections and thus too much energy for the corrections. The orbit around L2 is simply unbeatably far away and dark.
The pesky humans bumbling around the crew area would continually introduce small very annoying vibrations into the structure of the observatory. Much more efficient to keep the humans at a distance.
5:37 - Wow. To see another star system 27 light years away in the way you've shown that simulation of our own system - that would be AMAZING.
Thank you Dr. Becky for bringing Carl Sagan's voice back. Brought tears to my eyes. I was 5 years old when Apollo II landed on the Moon. And was glued to my small black and white T.V. listening to Walter Cronkite talk about it and Neil Armstrong giving the Iconic saying "One small step for man one giant leap for Mankind". Not to mention that NASA cut the public feed for 2 minutes, after Neil said "hey Buzz, they're watching us" and the glimpse of the Craft along the Horizon of the Moon. NASA NEEDS to come clean and release the footage and voice recordings from that time.
Even tho I still don't agree with Carl Sagan pushing to put Vetruvian man, the blueprint of Humans onto the Golden Records on Voyager I & 2, he is still a Great Man.
It would be nice if the next telescope had some sort of protection / guard against micro-meteorites that the JWST suffers from. (wish list)
At optical that possible since it doesn't have to be cryogenic
I’ve never clicked on a video so fast 😂
😂
You are charming, Dr. Becky and your contributions to astronomy are welcomed. You might like to know that Canada's largest city's library has your new book, as well as your previous one on time. I am subscribed here and look forward to future discourses!
Carl Sagan had the greatest, most soothing sounding voice and diction! I can listen to him for hours without getting tired of it!
I wonder how 12 meters was decided on, and what the largest size mirror we could put up there actually is... They only keep getting bigger, it'd be fun to skip a few generations (if possible) and build something ridiculously large (because its very likely we will end up doing that eventually).
Don't forget the cost of it and that it somehow has to get up in space
Eventually we will have to built it rigth out there.
Mining the asteroids for silicon and iron, smelting and producing the materials in space.
But for now we will have to be satisfied with about 15 meters or less for a single launch unit, any bigger and they will have to be sent in more than one rocket, because of the size and weigth.
That is the problem, the cost of the launch makes anything bigger proibitivelly expensive to send out from Earth.
What about that concept to make a telescope out of an inflatable transparent balloon, with a mirror surface on one side? Screw colonialism; you could launch the thirty meter telescope into space.
Wow, twice the size as the JWST ! so 20 years before they complete it ? Hope it happens a little sooner :)-
Great work!
In the style of Carl Sagan , you do a great job dumbing down some very profound ideas. Thanks for enlightening my love for space in a way we all can understand.
thank you for breaking it down!!With everything going on right now, the best decision to be on any creative man's heart is having a profitable investment strategy.
I agree with you and I believe that the secret to financial stability is having the right investment ideas to enable you earn more money, I don't know who agrees with me but either way, I recommend either real estate or crypto and stocks
I wanted to trade crypto but got confused by the fluctuations in price
@@adokadanla1407 The fluctuations of the market only affect those that hodl coins, but traders makes money on both sides, when it's bearish they go short when it's bullish they go long... The best strategy to use in trading crypto is to trade with a professional, like Arjun B Jagat he understand the market quite well, that way maximum profits are guaranteed.
@@mackea4651 I'm honestly surprised that this name is being mentioned here, I stumbled upon one of his clients testimony last two months in CNBC world news and decided to try him out...I'm Expecting my third cashout in 2days
I have heard a lot about Investments with Arjun B Jagat , how good he is and how he has helped People. Please how safe are the profits?
The Carl's version would be much more impressive than a mere deep zoom high res weather-telescope👀 (all Infared-JWST). But all these designs are over 20+ outdated increasing years of technology, summit as most modern. You only purpose of the mirror size, was through accumulation of light, this can also be done with multi reflect/refractive insecta eye wall set camera with multi sensor type in assembly form. Versus a massive mirror.
Being far more lighter weight,or size, with far more visual tweak features, and far less super-fragilistic massively overwhelming 🪞. Plus that would be the *real* modern so far (pending outdated again).
... And thus, you've managed to explain why you are *not* a designer of a space telescope, because what you just proposed was absolute horse manure.
@@ChaosCat79 Sir Manure? That wasn't purposed, that was the history of telescopes. Second, scamming humanity with outdated concept may be tax exilerating profitable, but not my field of work eighter. Nor is mine for sale. Which has *color, infared thermal, optical balance, electromagnetic, net lining gravitational wave sencors. + 7 new invisible into color night vision detect. As well, multi insecta-eye formation sync field lensing* tactic. ETC... Which is merely 43 year pass the jwst concept or 23 years modern since it was submitted launched, not one but TWICE from its first failed shedule.
This is fantastic news. Carl Sagan was a beautiful example of what a human being can be. It was a privilege to grow up as a child and be enriched by his Cosmos series and that calming voice that simply commanded my attention. 😊 this news has lifted my spirit immensely today. Thank you Dr. Becky
Just the knowledge that people are working and planning on this brings a tear to my eye. What a fitting name for a telly that could possibly show current, future, or even past planets that are/were compatIble with what we understand life can thrive on.
The Sagan Series from a decade ago now still inspires me even watching them dozens of times already. czcams.com/play/PLF17F07CFC3208E29.html
Carl Sagan is one of my all-time heroes
Loved the video (as well as oll your other videos I've seen so far). Loved the news, as well as the presentation. Loved a lot the transition with Sagan. Don't mean to be a party pooper but the sound would have been better if the transition from your voice to his would have been longer / smoother. Just a suggestion. Loved it, anyways ❤
Such a great channel.
All Hail Sagan !🤘🏻
Hail no...
Hail Sagan
