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.
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.
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?

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!
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! 😍
As a person of average intelligence I am just blown away by how smart some of our fellow humans are. It is ok to be amazed by their accomplishments. Thanks for sharing.
Have you heard of ancient Hindu book on astrology called Surya Siddhanta which literally means Principles of Sun written 5000 years ago? The content is much more baffling for that time
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.
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 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 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.
Exciting stuff!! 👏👏 Excellent video -- Carl Sagan really deserves this honour, he was a wonderful writer and educator!! "Contact" is still one of my favourite films ❤
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.
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.
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🙏)
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.
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?
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.
Your ending was the best! I love it when people let their hair down so to speak and have a little fun! You put a smile on my face with that. Thank you for the self promotion, that t-shirt looks wonderful. I'll put one on my self gift list.😊
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.
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! 👍👍😉😉
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.
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.
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.
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!
Every Dr. Becky's video should be viewed at least twice to support the TH-cam algorithm, first, because she is such a brilliant mind and a hardcore professional scientist, who also goes to such great lengths here to make us all little bit wiser about difficult space-related concepts. And secondly, because she is just so otherwordly and jaw-droppingly beautiful I'd drop my coffee cup in real life and run away blushing. Have to go buy her book now about Black Holes, hopefully one day we'll know what's truely behind the event horizon. Wishing all the best from Finland! 🙂 -Aleksi

Lol ITER is just another run on the long ladder that is Fusion. ITER is not aiming to achieve commercially viable fusion but to further push the envelope.
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
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
I didn't know the JWST was such an old idea, that's amazing to me. It makes me curious about what people will be able to come up with in the future. Imagine the possibilities and things we could achieve 40 years from now.
The idea that we might just be able to fill in a majority of the variables in the Drake equation in my lifetime is incredibly exciting. What a time to be alive!
Content like this is TH-cam 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.
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.
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.
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.
@@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.
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.
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 ❤
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).
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.
So excited! My copy of your book just arrived! Of course it probably arrived 2 days ago, but I just finished shoveling through literally 4 feet of snow to get to the mailbox to retrieve it (now, to get the car dug out LOL). Warmest greetings from lake effect snow country in western New York!
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).

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.
Might have missed whether you mentioned the other justification for big telescopes: that diffraction limits resolution. So there are quantum effects that imply a *finer resolution* for bigger diameters. Not just that the images are brighter.
Thank you for this exciting news. I recall watching the episodes of Cosmos on TV as the series was first released. Sagan was a wonder. Such a mind. Such ideas. And soon-ish, the Carl Sagan observatory. So wonderful. Now, to the merchandise.
Very appropriate. Carl Sagan 'COSMOS' series was a work of genius. I watched it and bought a basic Celestron telescope. Now I have the 'COSMOS' series on DVD.
I am so ready. My dad turned me to Carl Sagan’s Cosmos about 10 years ago and I am just hooked. I’m reading Pale Blue Dot now and still mesmerized but the things he thought the future would hold. Such as crashing a projectile into a asteroid to change its course.
I am sure it will happen. And Sagan was brilliant not just a teacher but far seeing and deep thinking, the reflection upon which many have been inspired to try their hand at and succeed. I didnt know you wrote a book will check it out!
Becky, as an armchair engineer, (retired EE), I have two thoughts on the design of the CS. 1) Build in orbit and move later 2) Make it modular and extensible by adding mirror components. yes I know - these ideas maybe $$$ or unreasonable for other technical facts. But now is the time to dream.
its funny as a 37 year old man, I still get emotional when I hear Carl speak. He holds a special place in my childhood and in my heart. RIP. Carl Sagan.

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.
Good to hear. I agree, the Carl Sagan Observatory is an absolutely perfect name for the next space telescope. Thanks for the video!
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.
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.
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.

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.
Erect a monolith on the moon in his honour 🤣
@@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.
@@peterdarr383 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
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!
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! 😍
As a person of average intelligence I am just blown away by how smart some of our fellow humans are. It is ok to be amazed by their accomplishments. Thanks for sharing.
Not only now, but the Antikythera mechanism dates from about 205 bce.

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.
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.
Gràcies!
Always a pleasure to hear from somebody with a gifted intelligence. Thx for posting.
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 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.
Patiently waiting to hear about the Trappist planetary atmosphere results!!! The Sagan Observatory sounds extremely exciting!
Exciting stuff!! 👏👏 Excellent video -- Carl Sagan really deserves this honour, he was a wonderful writer and educator!! "Contact" is still one of my favourite films ❤
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...
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🙏)
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.
I greatly appreciate, Dr. Becky, that you avoid segue advertisement in your videos; saving the sponsors to the end. Thank you, for this video.
Great video! Also, I love your last blooper. It shows me that you are not only incredibly gifted, but funny and connected to life.
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?
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.
a great honor for my favorite astrophysicist. I hope the Sagan craft gains a lot durability upgrades as we learn from JWST
Your ending was the best! I love it when people let their hair down so to speak and have a little fun! You put a smile on my face with that. Thank you for the self promotion, that t-shirt looks wonderful. I'll put one on my self gift list.😊
Thanks! Happy to hear this from a reliable source.
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.
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)
I used to love watching Carl Sagan’s television series, Cosmos. I’m pleased that this new proposal will be named after him. 😊
Nah. I'm not really sure on that. There's a reason he got the moniker "Butthead Astronomer"
@@metatechnologist What!? Nobody called him that. Get lost.
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.
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!
Every Dr. Becky's video should be viewed at least twice to support the TH-cam algorithm, first, because she is such a brilliant mind and a hardcore professional scientist, who also goes to such great lengths here to make us all little bit wiser about difficult space-related concepts. And secondly, because she is just so otherwordly and jaw-droppingly beautiful I'd drop my coffee cup in real life and run away blushing. Have to go buy her book now about Black Holes, hopefully one day we'll know what's truely behind the event horizon. Wishing all the best from Finland! 🙂 -Aleksi

@@briangarcia1540 Humor is very important, it makes us relaxed when we are sad or tense. It can also express joy or happiness. It also makes us bind and gain trust.
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
Lol ITER is just another run on the long ladder that is Fusion. ITER is not aiming to achieve commercially viable fusion but to further push the envelope.
@@zeitgeistx5239 yep that is post Iter
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
😅 thanks!
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 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
Carl Sagan had the greatest, most soothing sounding voice and diction! I can listen to him for hours without getting tired of it!
I didn't know the JWST was such an old idea, that's amazing to me. It makes me curious about what people will be able to come up with in the future. Imagine the possibilities and things we could achieve 40 years from now.
or 4,000
Long live Carl Sagan. May he rest in peace among the billions and billions of stars.
The idea that we might just be able to fill in a majority of the variables in the Drake equation in my lifetime is incredibly exciting. What a time to be alive!
That’d be cool, she really catches my attention and explains things that I can understand and interests in space with the way she draws you in
I'm liking the chapters structure to your videos.
Could not have a more worthy name for the successor.
Sagan was a righteous dude
I hope the name Carl Sagan Observatory sticks. Great legacy for a childhood star of mine.
I miss Carl Sagan. He was a true great of humanity... too good for this world.
He was a poet of science.
Great job, Dr. Becky !
*_TRUST !!_*
The fade to Carl Sagan’s speech in the end brought tears to my eyes. So beautiful! 🤩
Content like this is TH-cam 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.
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.
I’m looking forward to seeing “Billions and Billions” more galaxies from the Carl Sagan space telescope.
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.
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.

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.

👉🏆👈!!
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 ❤
I find all space stuff, [ Technical name for Astronomy ] extremely interesting and you explain it so well. Love your vids. Thanks.
So much universe, so little time.
Can you imagine in 12 years time saying "Carl Sagan found an earthlike planet!"
That's immortality of sorts.
Love this!
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 :)-
This is amazing! I'm excited to find out what we see. You are fabulous! I don't know if this is appropriate but I'm in love.
So excited! My copy of your book just arrived! Of course it probably arrived 2 days ago, but I just finished shoveling through literally 4 feet of snow to get to the mailbox to retrieve it (now, to get the car dug out LOL). Warmest greetings from lake effect snow country in western New York!
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
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.

Carl Sagan is one of my all-time heroes
Well, his voice was one reason. It was very Soothing to listen too.
My parents raised me on Carl Sagan's Cosmos series, I'd watch it in the morning, while eating lunch, before sleep. It was great, and he for sure shaped the way I think about our world and the universe
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.

It’s not a scam, that is from the producer of my merch, Teemill. You’ll get some Teemill socks as a freebie
Girl! I like the way you explain scientific data, fun and full of energy. I like your videos and my kids too.
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.
Loved the Pale Blue Dot,that mote, that spec of dust.
What a great honor for Dr. Sagan! He was one of the leading scientists when I was in high school and college, and gone far too soon.
Very cool, Becky!!! Thanks for this upload! I hadn’t heard of this “Sagan” scope… 👍
Might have missed whether you mentioned the other justification for big telescopes: that diffraction limits resolution. So there are quantum effects that imply a *finer resolution* for bigger diameters. Not just that the images are brighter.
Thank you for this exciting news. I recall watching the episodes of Cosmos on TV as the series was first released. Sagan was a wonder. Such a mind. Such ideas. And soon-ish, the Carl Sagan observatory. So wonderful.
Now, to the merchandise.
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.
Very appropriate. Carl Sagan 'COSMOS' series was a work of genius. I watched it and bought a basic Celestron telescope. Now I have the 'COSMOS' series on DVD.
I am so ready. My dad turned me to Carl Sagan’s Cosmos about 10 years ago and I am just hooked. I’m reading Pale Blue Dot now and still mesmerized but the things he thought the future would hold. Such as crashing a projectile into a asteroid to change its course.
I am in awe. This is a very fitting tribute for Carl Sagan too.
I am sure it will happen. And Sagan was brilliant not just a teacher but far seeing and deep thinking, the reflection upon which many have been inspired to try their hand at and succeed.
I didnt know you wrote a book will check it out!
Am loving your book, You explain things so eloquently 😀❤️
Becky, as an armchair engineer, (retired EE), I have two thoughts on the design of the CS.
1) Build in orbit and move later
2) Make it modular and extensible by adding mirror components.
yes I know - these ideas maybe $$$ or unreasonable for other technical facts.
But now is the time to dream.
its funny as a 37 year old man, I still get emotional when I hear Carl speak. He holds a special place in my childhood and in my heart. RIP. Carl Sagan.
I really enjoy your northern accent. I’m American, so I have no built-in prejudice tied to it that I have been told can be troublesome on your side of the Pond. It has a pleasant melody and makes you easier to pay attention to for me.
