- What’s the deal with the James Webb Space Telescope? On this episode, Neil deGrasse Tyson and comic co-host Matt Kirshen learn about the JWST and what new things it will help us discover with NASA astronomer Natalie Batalha and filmmaker Nathaniel Kahn.
Will this telescope help us find habitable planets? Another Earth perhaps? We discuss Nathaniel’s new documentary, The Hunt for Planet B, which follows scientists as they research and build humanity’s largest and most cutting-edge space telescope to date. Why was it delayed so much? Where is it being launched? What new engineering and feats of science were invented? What is it like to put your entire career into one object?
Next, we speak with Natalie and her journey to work on the JWST. Find out the two main objectives of the JWST and how it may help us glimpse into the past. We get into spectroscopy and how JWST uses infrared light. What’s the difference between JWST and other space telescopes we’ve launched in the past? Why are we looking for exoplanets? Are we planning to leave? We get into our patron’s questions: How big would a telescope have to be to see cities on other planets? Why do we choose to send up one single telescope instead of an array? What does Natalie want to discover? We explore best case and worst case scenarios. What happens if it doesn’t deploy properly?
What will JWST see that Hubble can’t? What would be the most exciting or surprising thing for it to detect? Can the telescope detect life? What about extrasolar objects like ‘Omuamua? What is the mechanism for how our moon formed? What is the usable lifespan of JWST? And finally, how will JWST further shape future generations’ vision of this world, just as Hubble had for the last generation of scientists?
Thanks to our Patrons Stefan Fox, Cortex MC, Brenton Verlo, taylor primm, Charles Shieler, Alden Doolittle, and Thomas Harshbarger for supporting us this week.

Hi Neil @StarTalk you once said that Oumuamua's motion was not natural, NASA believes otherwise?
Can the JWST see light from our early solar system somewhere way out there? Could it see past events like the Chicxulub impact?
@@chrisfast4469 we should search for a curved gravitational mirror focal length to Earth situated ~30.000 ly away. Joking, no way.
Though there's another way for the future if Galactic library proven to store that kind of information and gives us access to it.
Hey Neil, I have a question I'm just curious what would the JWST show if it was pointed at earth directly instead of beyond it?
@@schizophrenicpenguin5443 What are you intending to do man?
This was insanely good. My 8 yr old Nicholas and I find the day horrible when we don't have Star Talk. You have brought Science to us and make us so happy. Thank You.
Omy that's so warming to hear, thank you for doing such a good job, wish your family well, and hope you guys enjoy the holidays.
Get him interested in science and math from a YOUNG AGE! Show him how extremely gratifying it is when you finally find the solution to a difficult math problem! Maybe, 20 years from now, he'll be working on the next generation of NASA space telescope!
my son is 8 going on 88 haha but he is obsessed with science and absolutely adores learning from Star Talk. I adore him and today is Chemical Combo day! So the fun continues.
Your kids is 8 and already a old head
@@DonovanHaumpy He is an old head. He is full of so much Love and said Hello at 8 weeks old and hasnt stopped talking since. I wouldn't have it any other way. We both Love Science and this show makes us so happy. Love learning. Not to mention this Star Talk audience is so full of Love. You guys rule. Thank You.
Hi Neil! Great Star Talk!! I actually worked on James Webb for the last 14 years as a design engineer mainly on the Sunshield design and build. I supported the launch and the on orbit deployments. It has been a wonderful and stressful month, but the Sunshield deployed perfectly! Thank you for discussing Webb on your program, you sir are a huge inspiration to me, I always enjoy listening to you and watching you. If you ever want any details on the Engineering challenges we faced during the build of Webb, let me know! Take care and thanks again!
Awesome. Thanks for sharing!
thank you for your service!! hey- Natalie mentioned that if the James WEbb telecope fails its putting both her and "her daughter's" career on the line.. So her daughter also is a scientists who is involved with the upcoming science from the James Webb telecope?Do you know any more about that? and thanks again, i really mean that, as just a regular layman who loves everything "space" people like you really did a great thing for humanity!
I’ve really enjoyed the images that have come back so far.
I watched every video on the Webb Telescope yesterday. I couldn’t get enough. I fell asleep listening about it! I’m no longer sad because I can watch this now!!!
This is ground breaking, a big step in human history that we know of, I can't wait to see what the J Webb can see 👀 🔭🌌🪐
Space is fake, nothing can leave The Dome! Just kidding, I'm extremely eager to have this happen, too.
thanks captain obvious, but we are counting our chickens before the hatch
I feel a little more educated everyday thanks to this show. I’ve started to see and think differently thanks to you guys. I can’t go to bed without watching or listening to Startalk. Thank you for dedicating your time to do this! Greetings!
You are simply becoming more conscious and aware. That's beautiful! Keep gaining knowledge and working positively on yourself.
The alien planet 😨
Bulma knows a lot about everything she can help you too.
Well said dude 👍👍
Well said. I've read this in Vegeta's voice.
The successful launch AND deployment of this amazing machine will mark a new era of human history. Let's get it up there!!!
Couldn't agree more! I'm so excited, we just dropped a rap about this! 🔥🔥🔥🚀🚀
The 6 months once it gets to the LaGrange point and goes thorough all it's testing is going to probably the most stressful 6 months for a majority of these scientists careers ever. The JWST is a career making or ending project for many people. This thing probably has so many redundancies and precautions when it does start working is going to change so many scientific theories and explode new avenues of science. Very exciting times.
The absolute PEAK of currently-available human engineering and materials sciences. I suspect that specifically the three days it takes for the telescope to "unfold" will be the most stressful for them.
36:00 in, or so ...? 🤣
For me, every second is stressful. I search every damn day multiple times about the current status of JWST. Imagine being the scientists and engineers who made this possible.
Inspiring, Dr. Batahla 🙌🏻💞 This was a great talk, dynamics of communication styles, information, explanations, and more! Thank you Neil, Matt, and Natalie.
May be the most important 56 minutes of my life listening to these geniuses. Incredible JWST !
Wonderful Individuals! Yes the JWST is a beauty. It only has 1 chance to travel 1million miles and get 300+ parts to work correctly. Legendary!
@@biointelforce I wonder what will be in store in the next 20 years? It's too exciting. Best to keep the eye on the now, which is exciting in itself, at least right now.
@@badcornflakes6374 That is one of the best things in Life, to wonder is how we keep advancing. Happy New Year to you.
Natalie Batalha is awesome! I could listen to you talk all day!
Not going to lie, I am super nervous about the James Webb Telescope working. I reaalllyy want it to work!
Tyson VS. Mabuz czcams.com/video/jCLbEYm-jiE/video.html
Yep.
Us science folk are definitely anxious.
For real!!! I've been excited about this for a long time, been waiting on its launch for what feels like forever‼️We still have 6 months to wait because it needs to be setup, tested, and things like that. Hopefully they report the test results, I don't wanna wait forever I just wanna see a good picture from it 😭😭😭 I don't wanna wait a year + for the first picture
@@ActionJackson669 Totally! I still fool myself in thinking it'll be launched and 'voala' amazing insight!
I remember my biology teacher talking about this telescope back in 2004. I always check in on it.
Now I know how to tell people how old I am when they ask without giving my actual age-I'm archeological. Dr. Batalha is amazing with her unreal passion for this project. It is so good to see that enthusiasm these days. Thank you Neil and Matt for this episode and looking forward to seeing Mr. Kahn's film.
If all the science teachers all over the world shared that enthusiasm while teaching, the people in scientific jobs nowadays would've been tenfold and we would've been to Mars and established colonies already, especially when some of those students made to the level where they get to make decisions about how much budget goes to science development. I was in shock when Neil told how much budget Nasa gets. It's disgusting how little they get.
@@chino8646 like always, the blame is on the teachers, people is always finding a way to avoid blaming the real responsables for the educational problems...
@@chino8646 It really is pathetic that NASA gets so little funding compared to the military and other agencies. Explains why private industry partnerships are becoming more prevalent. Unfortunately those partnerships benefit the private sector business community more than the overall population as we have seen with the recent billionaire blastoffs. Sad to think of space as the next frontier of commercialism.
@@josewemersondasilva9040 oh don't get me wrong, I think the main reason why the most of the teachers are not as excited and enthusiastic as they should is cause the government doesn't give a crap about the educational system. However, there are many who are very enthusiastic and they show that through their teaching despite the lack of means and interests the government shows. It's that enthusiasm that gets the scientific juices flowing so to speak in young kids. They need to get excited about science and get triggered about science
Excited to finally see this telescope launched. I hope everything works as planned.
I couldn't watch or watch videos like these until it launched and started to deploy it's gold panels.
Rash, everything turns out great. You will see. 🤔
This is My favorite show
I love how Neil explains everything easier to understand... thank you
Tyson VS. Mabuz czcams.com/video/jCLbEYm-jiE/video.html
He's a fraud
@@bensavage6389 Hey nobody, I believe you 😂
@@bensavage6389 jealousy
Thank you both, Natalia & Nathaniel for being a part of this awesome interview episode 😃 I found the fact mentioned that footage gathered by JWST will be freely available, to the public, in an archive. I can totally imagine the applications for which amateur astrophysics, hobbyists & enthusiasts will be able to make use of this data, and I’m excited for all the revelations to come 👽🖖🏽 The idea of a Lunar Base being able to someday service L2 zone space-telescopes is beyond incredible to imagine 🌌⭐️🪐
I'm literally so excited at the possibility of humans finally discovering an atmosphere on another planet that would confirm intelligent life in the universe! It's so mind blowing that we now have the opertunity to see this far out. I wish we didn't have to wait approximately 6 months or so until its ready to actually start checking out these earth like planets 😁 This next few years could be the time where the biggest question in the history of humanity is answered.. 😳😖🧐🤯
@@okinnivlek I'm not at school, I'm 42 🤭 As far as I'm aware, the James telescope will be able to detect biosignitures in the atmosphere of planets, like oxygen and methane that could indicate life on the surface 😁 The excitement is real 🙏
@@Onestringpuppet I just heard her say the opposite.
it' won't confirm intelligent life, it will simply allow us to understand more about the atmospheres of exoplanets.. These finding would indicate the possibility of habitable planets and the potential for life. There is nothing about confirming intelligent life in this mission.
We already have on a few planets that are relatively close, but none had the composition expected for life. We also need to remember it will not confirm anything. It will just give us access to a larger data pool.
@@themagicguy1 we've already discovered over 4000 planets outside our solar system, I'm just excited at the JW being launched and joining in on our hunt, to help answer the greatest question mankind has ever known 😀
Natalie Batalha must be an amazing professor. The way she talks about physics is really exciting.
Wonderful discoveries to come!!
@@uniquemetal 🙄
I sure hope so!
I learned a lot about rainbows and white meat 40:37
I hope we suceed. I only wish Carl could be with us to celebrate this Wonderful adventure. Extrodinary claims require extrodinary evidence. Maybe JWST will provide that evidence. I'm proud of all of you. God speed.
Aren’t we just an amazing animal that we cultivate individuals and sciences that not only allow us, but motivate us to do these things, and that we like to talk about the journey of getting to JWT as you mentioned in the video that the passion is amazing.
This is going to be awesome seeing the scientific discovery’s JWT and it’s team unfold ,it’s going to be truly majestic 👍
I hope they will make more than one discovery.
I hope there will be another season of Cosmos compiling all the information gathered by the James Webb
I agree, but it will take a LOOOONG time to get it started, let alone to get enough data to make a 12-15 episode season with 45 minute episodes. So we have a LOOOOOOONG time to wait my friend 😭😢😭😢😭 But someday, it is definitely deserving of something like that, I'd be really happy with it. Hubble was the most useful scientific tool maybe EVER, as far as how many scientific papers were written based off data coming from the Hubble Space Telescope. It had thousands of papers written based off it's discoveries, so Im hoping that the James Webb Space Telescope has similar success‼️💯 That would be great for humanity in general, I'm excited I been waiting for this for a long time. Still 6 months to wait until it's functional 😭😭😭 I'll be impatiently waiting for that day
I know am not the only one that feels peace and is able to disconnect from the daily stress by going to sleep to this kind of videos ! Love Star Talk !
Did anyone else notice the James Webb Telescope pin that Dr Batalha was wearing? Great interview.
“Worry is not a particularly useful emotion” is the single greatest thing I’ve ever heard. I can’t understand folks that worry about everything all the time!
Most people lead with their emotions, one should lead with logic.
Worry is very useful when we worry about the correct things. Worry helped our species survive, but I know what you mean.
I loved that she said where are not on that Colonizer mentallity lets keep that overhere and look for planets with the mindset of learning from them and appreciate our home
Amazing how you start to make a documentary about a telescope and ... it turns into about the people. Can't wait to see it!
Nathaniel and Neil have this amazing chemistry in which they can explain clearly and in a moving way the greatest frontier of discovery, I am truly thankful for the knowledge, wisdom and humanity that gets to be shared with each and every one of us. Thank you to everyone on the StarTalk team making all of this possible! Keep up the amazing work!
In organic chemistry, we commonly refer to organic synthesis as "bucket chemistry" since it seems a bit like we are just throwing stuff in a bucket to make our target molecule.
After this, I think I'll start referring to telescopy as "bucket physics"!
If the JWST were to look at our solar system, it would (likely) detect 3 planets in the "Goldilocks Zone", which planet would be most intriguing for life? My guess would be Venus, due to its prominent atmosphere, unless JWST is able to resolve details of the planet about which I am unaware.
@@agchav98 Actually it is Venus that got this whole planet finding thing started. The PVO, Pioneer Venus Orbiter, and Soviet probes relied heavily on spectroscopy and there was a star sensor onboard. That was fantastic for two reasons: 1. It was used to triangulate star location/distance with Earth readings and help map the stars giving Hubble and Kepler an outline for correlating and verifying data and interpretations. 2. The PVO spun around once a day allowing different sensors to face the planet or face the stars. The star sensor was thus pointed at the planet half the time though no one thought to look at that data since it wasn't relevant to the designed use of the equipment. That was until a Soviet scientist reported radio wave fluctuations consistent with lightning in the atmosphere of Venus by way of their orbiter, and Bill Borucki decided to look at that star sensor data when it was pointed at the planet. Not only was he able to confirm the light flashes but to get a rough idea of their spectra and know which gases were interacting in the plasma of these atmospheric events. There was a wide rabbit path of science that took off from there that was about origins of life, planet hunting, exo-everything-ology, and including laboratory verification of prebiological molecule production. Borucki also built large diverse teams to work on this starting with high school students operating lab experiments and working on the first planet finding techniques at Lick Observatory with a mouse named Spock who lived there. More scientist came on board outside of physics including biologists, chemists, engineers, etc, all looking at the same data with different eyes. There were small teams on each area that would collaborate with the other teams like a bunch of interlocking gears. That may have been his greatest gift to us (Kepler was pretty good, though). One of those high school kids, by the way, is one of the directors at NASA-Ames where it all began.
So, no, they wouldn't pick Venus as it has been extensively studied and its type easily identifiable. Mars would be out due to lack of sufficient atmosphere. Earth would be the choice. My hope is that someone figures out a way to test for water vapor, liquid or ice. That would speed up the process of selection enormously.
Can’t wait for this telescope to launch, great show thank you so much
Tyson VS. Mabuz czcams.com/video/jCLbEYm-jiE/video.html
Same! It's gonna bring some major insights!!
I can’t wait either, so I can stop hearing people needlessly gush praise and excitement over a telescope that hasn’t done anything yet to advance the science of astronomy or astrophysics.
@@JROD082384 lol, your comment is like buying a TV and moaning that it doesn't show anything, before you've even plugged it in. 🤦♂️
@@mabuzlouisofficial You heap big dum dum
Can I honestly listen to her answer questions all day. She's entertaining, knowledgeable and honest.
Ok, this is the second time I have seen the JWST pin, and I want one.
Iv been so excited for this for so long. I hope the journey to space is safe and it gets there with no issues❤❤
Love listening about the new tech allowing us a further view into space.
Love the way how Natalie answered all the question. Her voice is full of positivity and calming.
Terrific show Neil! Now I know a lot more about the JWST and what it's mission is thanks to Natalie! Fingers crossed for a successful and uneventful launch. 👍👍🤞🤞🤞🤞
I’m definitely going to watch this when I have time. I’m glad Neil is weighing in on this, I always love his take on things! He’s awesome.
I'm excited for all the possible studies and data that can come from this instrument. But let's be honest this is the biggest upgrade to our desktop wallpaper we're gonna have for a while
We already have artists renders
I’ve seen all available lectures by Natalie Batalha, she’s an excellent and enthusiastic divulgator on exoplanets science. I admire her so much!
I'm excited about all the possible discoveries using this telescope.
I also like the pin Natalie is wearing, very cool!
Here I was taking in all of the knowledge about the James Webb space telescope as well as about exoplanets that Natalie Batalha is host to when Natalie pummels me with her exceptional humanity about the pale blue dot and the life that it is host to. Natalie's advocacy for discarding harmful rhetoric places me in a welcomed state of awe! Thank you for sharing this interview of Natalie and of Nathaniel.
I’m so ecstatic about this🤩 . This new tool is going to open up a lot of secrets that our universe has. I really hope they find habitable planets! It’s definitely going to be a game changer for us!
My personal astrophysicist...please keep it up. I look forward to and search daily for the next post. Thanks always!!
I am so glad that people care about this important task and I love you all for it! Go Webb!
The James Web telescope reminds me of a giant Origami sculpture! It's beautiful! Not just a marvel of engineering, but also a work of art!
Was waiting for an episode on this topic. Thank you.
Thank you for covering this !
I have been following Hubble for as long as I could, my excitement of learning about James Webb was/is more, how incredible is man. Tears fell when watching the lead up to & deploying of James Webb
This is going to be amazing. Its better to have tried and failed than to have never tried. They had to create several technologies to get this done. That alone has merit
Nothing ventured,nothing gained...and ,yes, what they developed just to make this will pay for the cost of it in the long run. (even if it doesnt work it will be worth it).
Really excited for what this telescope will teach us
This is the only Christmas gift I want.
Idk why I'm so happy to read the comments, it's my first time in a long time to see a healthy environment for science.
“Worry is not a particularly useful emotion”. Words to live by!
Love your program. L2 is only a distance that will be traveled if someone decides to do it.
“Only”
Natalie was so insightful and articulate! It was amazing listening to hear her speak
I hope they look at the Trappist-1 system
Glad to see fellow high schoolers listen to these although I have a hunch most of them are much more studious than I am. I’m not a bad student but I don’t prioritize school/college I’m more of an entrepreneurial spirit however with the power of CZcams I’ve developed a deep fascination in astrophysics and this show is one of the key pillars of that🤝 thanks dr Tyson and everyone else keep it up

thank you Neil, you made a significant change in my perception of our life. Reasoning and rationality are more powerful and satisfying than faith or spiritual beliefs
Say no to bfrGjmib quota.
Thank you Neil for educating the world about our World! 😃
44:13 - Neil grows so desperate as he badly wants to know the next new molecule to be discovered.
This episode is sooo cool👍
I get so happy when I hear his voice or hear that Star Talk theme tune. Life is wonderful all of a sudden because I get to learn and talk science.
I’m so freaking exited for all the data and research possibilities will unfold it will be amazing
I'm waiting for 20 years.
Will be my Xmas present this year.
Natalie was excellent, great answers 👏
Loved the info as always...however, where is Lord Chuck?!?
Hopefully removed.
Who else enjoyed the view outside of her window?
In 2019, a tree saved a family's home. And I maintain the tree saved my life as well.
Due to the power of the impact, the tree assisted my car in separating into two sections, thus absorbing 80% of the impact while stopping my car from hitting a home. Not a single broken bone and I crawled out of the mangled front section on my own.
Since that day, trees have a beauty I had never noticed prior.
Super Tree
I knew someone who constantly recommended the novel "The Overstory" by Richard Powers where trees are tied in with people's lives. I haven't read it myself though, but it sounds intriguing.
finallyy!! the topic i have been waiting for ! this is the only channel that i like videos before i watch :)
Nice episode, already waiting to hear from James again ;)
This is great!
I will be following this closely.
If there are indications of advanced life forms, please (and I can't emphasize this enough) do not attempt to contact them. Keep in mind, they do not actually have to travel here to harm us.
I believe highly-advanced life forms already are aware of us and are interested in us. They know I know. It's because what I figured out.
I am not crazy.
:D
you,re not crazy its the universe , they are already here of course but science has to confirm it too
Everybody cross your fingers so the telescope gets where it has to go and work as it should!
Watched the launch this Christmas morning live; beautiful perfect launch (ideal weather) with flawless delivery --- as exciting really, even more so, as the Saturn V Apollo project of days long gone... today was the highlight day of the year! ... actually, of the last two decades!

Im so excited. Its happening! Godspeed JWT
Excellent broadcast. Thanks Natalie for the insights. Our future remains ever bright.
Neil looks really "happy" in this video. One of the many reasons I love this channel, haha. Cheers! 🪐

Matt always does such a good job
I told my friends about this telescope years ago! If all goes to plan this is going to be the biggest advance in astronomy maybe even proving life exists on exo planets.
If we can find planets with oxygen atmospheres then we can estimate f-sub-l in the Drake Equation (and the version I prefer by Carl Sagan). If we can detect pollution, like Romans smelting lead and silver, then we could estimate f-sub-i too. Unfortunately, I got to the point where they said this telescope won't find oxygen.
The next telescope is for that. This one is not for that. It can not block the light of the stars to look at the atmosphere
I'm in ❤ with the Space Telescope & he is a Genius Neil deGrasse Tyson.🤗
This was a great episode, thank you!
Natalie is a cool customer. I'm more exited for the Launch of this telescope than I am for Christmas this year!
I'm excited to see what lies beneath the atmospheres of the exoplanets! Finding life would change our ways of perceiving life.
She said it won't find life and that it wasn't built for that.
Love the show, keep it up ! ^_________^
Just finished reading the Three Body Problem series, not sure I want to find any exoplanets right now...
Wow All of you guys did a marvelous job Natalie was exceptional and so passionate You are taking the world to the next level👏👏👏👍🏻👍🏻👍🏻👍🏻
Does Webb possess the capacity to actively [cooperate] with other telescopes, like Hubble to improve imaging? I get we haven't perfected those kinds of interferometry technologies. But we're taking advantage of opportunities to play with it, right? 🤔
Well actually Hubble observes the photons from visible an ultra violet spectrum, whereas JWST observes in infra-red spectrum. So I don't think it takes the help of Hubble.
Also, how cool would it be to point the telescope at an exoplanet to see their telescope pointing back at us!
One of the channels where I click 👍 before even watching.
Hi Neil! I'm your brazilian fan.
Hopefully they find some form of intelligent life out here because here on Earth is extremely rare!
haha, good one... but think next gen telescope...
Man I love how excited she gets it really drives this stuff home how on the cusp of new knowledge we are .
Where's Chuck?? Matt is a good guest but I love Chuck. Bring back Chuck!!! Great video by the way, as always.
Its really great they talked about James webb telescope and i hope the launch goes well too it will be like huble on steroids
Inspiring work! I have a question: as long as the big bang occured in the past and the radiation is still coming towards the earth from far deep space, I assume that the early radiations passed the earth and going beyond, in other words, we lost a lot of early radiations and we are observing more recent radiation which means that we missed the radiation that could be 100 billion light years old. Hence, how we decided it 13 BLY old?
Brilliant question! 👏
Well, it's a bit more complicated than that how they actually calculate the age of the universe. One is the MW background radiation. Then there's the increasing expansion rate of the universe which you can trace backwards.
However, "age of the universe" in scientific terms refers to the time elapsed within the _currently observable_ universe since the big bang. They just don't say that each time as it's sort of a given. So there's a chance that the universe is older than we know today. But it's the best we have for now.
I had the same question once, and this answered it for me:
The Big Bang was *not* an explosion that happened *inside* the universe.
The universe *is* this explosion! We are inside of it.
Therefore no matter in which direction we look, we will always look at the Big Bang so to speak.
The simple explanation is this: "we" as in our position in the universe and the source of the 13 billion year old light were at the same place when the big bang happened. The universe had expanded quite dramatically in the unimaginably smart fraction of time "after" the big bang, and continues to expand to this day albeit at a much "slower" rate. The actual age of the universe is determined by other astrophysical observations... not by the age of the oldest light reaching us. In fact as the universe expands, every second, more and more of distant light is going out of our view. i.e., it will never reach us.
I think they used the Cosmic Microwave Background to calculate that .The CMB is a kind of light/fingerprint created by by the Big Bang which has characteristics that sceince can study and deduce useful calculations from.
Matt did a great job in the episode 👍🏾
I do love the Tuesday explainer ones
Watching StarTalk without Chuck is like watching Warriors’ Steph playing without his pick & roll partner Draymond Green 😂
😂 UC Santa Cruz is the only university I've ever seen that has idyllic RV housing with gardens in the forrest, like the old silver winnebago types. In certain parts of the campus it's kinda like how it would be if Ewoks started a university. Literally high wooden bridges through the redwood trees
Really? That's pretty cool
This was so interesting, thank you! I can't wait to learn more about it.
I'm really looking forward to hearing about the discoveries made by the JWST.
Neil’s voice makes you Visualize what he is explaining till you fall asleep, perfect for a Documentary 😂
