An international project like this that has countless “firsts” takes time, but the painstaking effort to design, construct and test Webb’s optical system will be worth the wait. Overnight, the eye of the telescope will revolutionize our understanding of the cosmos and be set loose on the biggest questions in astronomy.
The astronomical community was after something that hadn’t been observed before… the early universe. The first stars and galaxies started to form 100 to 250 million years after the Big Bang, around 13.6 billion years ago. Because the universe is expanding, actually the light from the early universe gets stretched into the infrared and that's called a cosmological redshift. It's this cosmological redshift that Webb's optics will be hunting for, to uncover the story of the early universe. Infrared light can pass through dust in the universe. And so it allows us to peer through dust clouds and see, for example, stellar nurseries.
No other telescope today has the collecting power and sensitivity that NASA’s JWST has to lift the veil on the universe’s secrets. The James Webb Space telescope is sensitive enough that if there were a bumblebee at the distance of the moon, we would be able to detect it. The telescope’s core superpowers come from its advanced optical system.

Webb vs Hubble Telescope
www.jwst.nasa.gov/content/abo...
“Webb often gets called the replacement for Hubble, but we prefer to call it a successor. After all, Webb is the scientific successor to Hubble; its science goals were motivated by results from Hubble.”
The Five Big Ways the James Webb Telescope Will Help Astronomers Understand the Universe
www.smithsonianmag.com/scienc...
“The further into space scientists can look, the further back in time they can observe a galaxy. Webb, being the farthest seeing telescope yet, can root out the youngest looking galaxies humanity can observe.”
The Webb Space Telescope Will Rewrite Cosmic History. If It Works.
www.quantamagazine.org/why-na...
“The James Webb Space Telescope has been designed to answer many of the core questions that have animated astronomers over the past half-century. With a $10 billion price tag, it is one of the most ambitious engineering initiatives ever attempted. But for it to achieve its potential - nothing less than to rewrite the history of the cosmos and reshape humanity’s position within it - a lot of things have to work just right.”
The $11-billion Webb telescope aims to probe the early Universe
www.nature.com/articles/d4158...
“If everything goes to plan, Webb will remake astronomy by peering at cosmic phenomena such as the most distant galaxies ever seen, the atmospheres of far-off planets and the hearts of star-forming regions swaddled in dust. Roughly 100 times more powerful than its predecessor, the Hubble Space Telescope, which has transformed our understanding of the cosmos over the past 31 years, Webb will reveal previously hidden aspects of the Universe.”

![Everything NASA Discovered from James Webb's First Year in Space [4K]](http://i.ytimg.com/vi/nbDQEo0uA0Q/mqdefault.jpg)
JWST is launching this week! Which cosmological questions are you most excited about the telescope looking into?
exoplanets for sure!
The fuel is only 10years? that's so short of time,and in the 70s the voyager 1 survive more than 50years. I'm just gonna create a replica of JWST because im bored
@ but it can detect liquid water, which in itself, is proof of the possibility of life. It’s as if someone handed you a bag of money and you complain that it’s not in a briefcase.
I want to see if it can find the edge of the stellar universe and what the pre-stellar universe is like. I’m giddy with excitement wondering if there is unknown supernatural phenomena about to be discovered. It’s both exciting yet terrifying at the same time.
How the telescope will be pointed to particular place? Since its open mirror in space and light always reflects on mirror.
James Webb could be the best Christmas gift for all mankind.
So true, hopefully all goes well
It definitely is for me
Christmas is a pagan religion, so please don’t apply your believes to all mankind
@@incelhindufreak1706 what are you even talking about
@@yamizake5527 what religion has to do with science?
Imagine an intelligent alien race 3 billion light-years away also launch a James Webb telescope at the exact same time as we do. If they pointed it at earth, they would see an uninhabitable lava world and assume life could not exist here. wowee spacetime is weird o.0
They would see the planet Earth of 3 billion years ago. At that time Earth was already a planet full of water and micro-organisms.
@@weirdocreep2471 true, they would have a thought that there is an extreme chance that the life still exists there.
That's the funny twist. That we cant see much as is now.
Here comes the atheist. Lol
@@motoporn9055 what? You make no sense
I'm in awe of the dedication, creativity, ambition, and wonder that propell the NASA teams designing and building this new telescope. With all the trouble in the world, political shenanigans, looming environmental/social crises, short-sighted economic greed....projects like JWST remind me of the long game, that deep quest of discovery and wonder of our place in the universe. We have come so far in that quest, yet is seems so fragile, our own hubris threatening to collapse our foundations of scientific curiosity. Fly safe, JWST. We will wait eagerly for the first glimpse at the earliest light from our universe.
what a beautifully written comment! I appreciate people like you
@@fireantmedia7946 Aww thank you! I appreciate you too. Just trying to make our corner of the internet a little brighter. 😃
That's why we do it!
I can't even imagine how genius scientist and engineer team behind this marvelous telescope. Their endlessly effort will boost our understanding of our universe. Even it will make science book more thicker I'll definitely read it.
These so called brilliant genius nerds and geeks can't even figure a way to end all crime, suffering and natural disasters. All that looking and staring into space is distracting everyone from what's truly important. You guys watching too much Hollywood crap😉⭐🌲🕯️☃️
@@Hundert1 How about you stop using strawman fallacies and false dicotomies to undermine the work done here? Do you even know how much of this technology reverts back to things like healthcare and environment protection? Do you even realize how "trivial" things like the software algorithms developed to de-blur Hubble's images are the backbone of modern medical imaging, from CT-scans to MRIs? How much of the satellite imagery we get from earth helps estimate deflorestation, and pollution, drought, storms and plan better to fix and cope with it? It's not the scientists' fault that all these advancements halt at the politics stage.
Curb your self importance.
@@Hundert1 You should ask these so-called "brilliant" scammers and frauds - the Pope, religious preachers, Wall Street banksters, useless freeloading billionaires like Bozos & Musk, and mega-rich entertainer - to do some real useful work for once and some real problem-solving, and fight for worker unions, Socialist & Liberation Party to end freeloading billionaires living off the labor of workers.
Go attack THEM, and tell THEM to do USEFUL work, rather than attack incredibly hardworking engineers, computer programmers, machinists, scientists, science administrators, educators who pass along knowledge & skills.
Books will be all digital."stop cutting trees"..
Science is frickin' awesome.
And then there's social media"science" 😂
Really - cosmology maybe awesome lol
The more you discover and understand science, the more awesome it become
Imagine that tomorrow, scientists find out that we are in fact living in a simulation. What do we do? Could we continue living?
@@twuandixon8675 Thank you for putting the word, science, in quotes, after "social media".
Can't wait for the James Webb to find what *exoplanet atmospheres we could breath in!*
2023
@@_UTTAM_ what's that ?
@@com-ev5wq year
@@_UTTAM_ so it will start working after 2023 ?
Can't wait for the billion dollar failure.
I’ve been waiting literally my whole life for this, it’s almost hard to believe it’s about to launch
Can't wait to see what the James Webb Telescope is going to show us this universe is amazing it would be awesome to see it up close
Ya but it wouldnt look the same up close
@@solodus12434 Not even remotely. For anyone that doesn't believe it, just look at Andromeda, and then the Milky Way around you. No similarity whatsoever. But there would be from Andromeda, looking back at the Milky Way.
Also what Webb (or anything else that can) will be looking at is what it looked like THEN, not now. Those stars are actually something like four times as far away now, and forever out of our view, unless we can exceed light speed, by a LOT.
If it can find something strange in universe, will Nasa reveal it to public?
@@SK-pb1fs most likely as most of what Nasa discovered about the universe is open to the public, not 100% of the things discovered but at least more than half of all discovered things.
not just nasa though.
It will be awesome to see what we learn and what that telescope teaches us. KUDOS to the builders but personally no interest in seeing the telescope itself But intense interest in what the thing will teach us!!
Give These scientists a whole lot more money! They deserve it
Definitely
And how exactly do you propose to contribute your share?
@@debayanDas Take the money from useless Wall Street banks, Amazon CEO billionaires, billionaire scammers like Elon Musk,
and useless churches.
exactly
@@theultimatereductionist7592 stop using their products then. Have seen many keyboard warriors like you. Commenting on or blaming someone is easy. Go out there and actually do something productive if you really want to solve that problem.
Finally it's launching, now all we have to do to is wait one year
a year for what
@@nanoman81 5:42
@@balti1991 You misunderstand. He said that are the things they will be locking at in the first year. Not that it will take a year.
@@motomass8458 Maybe, but apart from the exo planet discoveries (maybe even that), i think a lot of the stuff will take time (processing, confirmation etc.), a year i think is an ok assumption for me, am not going to get my hopes up for hearing anything, before that
@@balti1991 I feel like a year is quite a long time. But I have to agree it will take some time before the first photos are even taken. Remember that the telescope will have been disassembled and it will assemble itself after launch, which may take a few weeks or months
Other people: *gets typical Christmas presents*
Me: James Webb telescope launch is MY present
The _Christmas_ gift should be a successful launch and full functionality in space for the JWST.
This is our Christmas gift for better understanding of the universe.
Who ever waited 20+ years for this. Your day is finally is coming.
When I was a little child I remember my dad telling me about it and now it's finally going to launch
ME !
Some people actually think that this is all a waste of money 🤦♂️
The same people who think the Earth is flat probably.
My mum literally.
More understanding on how the universe works is never a waste of money.
Also when we do stuff like this. New technologies are usually created.
Some people are idiots.
Rather have the US build this than bombs which are truly a waste of money.v
more than two decades of inovations, craftsmanships, collective minds of most brilliant scientists, engineers, and centuries of knowledge of telescope since Galileo stared the night sky.😁😁
Phenomenal video we have been looking forward to this for many years keep us posted
Cant wait to see some pictures from it :)
Arthur C Clarke’s books were such an influence on me as a youngster. So much so, I use to go outside and just stare at the stars (my eyesight was near perfect back then!) and imagine what was “up” there… Fortunately for me, I lived on a remote pacific island and there wasn’t any light pollution and it was breathtaking at how the night sky would be lit up on a new moon. I could occasionally see satellites move across the sky. OH THE NUMINOUS NATURE OF THE COSMOS!
I can not say how excited I am for the James Webb telescope, the people you engineered it, built it and will be using its data to see further than we’ve ever seen before. It’s truly a testament to what humans are capable of accomplishing and I can not help but imagine that Arthur C Clarke would feel the same way.
Cheers!
This is going to be EPIC. 👌🏾👌🏾👌🏾👌🏾
This is truly beyond amazing
Im nervous. I hope everything goes well with the launch cause if the jwst blows up im gonna cry 😭 25 years in the making
Well we could make a new one or better one in less time because a lot of time went into the new technologies of it. But budget would of course be a problem
The launch isn't the problem. You should be nervous for the deployment in space. Hundreds of different components need to deploy if 1 fails the whole telescope fails..
@@mentos93 I think you meant the launch is the LESSER problem. It IS still a problem. Satellite boosting vehicles do still exterminate themselves on the pad or in flight on occasion. There is a reason that satellite insurance exists.
But I agree that the problematic deployment is a far more likely scenario, one which I very much hope does not occur. If there is a serious launch failure the chances of a botched on station deployment go to zero, unfortunately.
@@MrJdsenior true, but i have complete trust in the ariane rocket. Out of 111 launches only around 5 of them failed. I really hope this telescope doesn't fail.
@@mentos93 either way its gonna be clenched butthole and crossed fingers for the next month 🤣
Peering into the soul of the universe
With glassy yet clear eyes
It is a legend in the making
A glistening flower that needs the cosmic realms embrace to blossom into knowledge and understanding
Golden petals bright and beautiful
The cosmos introduces her children to us with a broad smile
Grandfather Hubble gives one last salute as he welcomes his fate with open arms
He has served his country well
But time to peek into the deepest realms of the universal mind.
A new age is happening
Wow what a poem well wrote
I also want to be an Astronomer / Astrophysicist
Awesome poem! We just dropped a rap explaining JWST maybe you should cowrite the next one! We both refer to peering into the universe's soul 🔥🔥 Great minds think alike 🚀
Mind blowing wow and can't wait to see what information comes back and what we can see from this amazing work of science art.
Oh brother 🙄
Thank you to everyone who had a hand in making this master piece.
No problem, my pleasure
Wonderful, very, very & very best of Luck (y) !
I now have a bit more understanding of what its about. Thanks.
So excited for this
Hope this goes off without a hitch! Been waiting forever for this thing to get out there
FINALLY !!!!!!!!!!!!!!!!!!!
Can't wait to see what additional data about planet earth this telescope is going to generate.
IM SO EXCITED!!
This is going to be wild!!!
I’m so excited 😆 like I’ve been fascinated since I was a small child
I wish best of luck for James web telescop. I wish it bring us highly interesting and useful information. 👍
I can't wait for it
thank - you .
I am looking forward to it....
0:06 , "Webb is the largest telescope to have ever launched into space.". Hold up. It hasn't launched yet, buddy. Don't jinx it by acting like it's already launched! We've already been delayed enough!
If it ends up being delayed past the 24th, I'm blaming the narrator of this video for jinxing it.....
Well he did not say to "have" ever launched into space he said "to ever launch into space," it's just one word that can change the whole meaning!
@@jk-gb4et not according to the closed captions that I get when I turn them on. It shows me " to have ever launched" not "to ever launch". Could be discretion in the automatically generated CC's, but I'm not sure. All I know is that what it shows me.
@@BackYardScience2000 Listen to it with volume (unless you can not hear in which case i do not know)
@@jk-gb4et that's originally what I did. Also the reason why I turned on the closed captions to make sure that I was hearing what I thought I was hearing. It still sounds the same to me. But I could be wrong.
Kudos 👏🏻👏🏼👏🏽👏🏾👏🏿
would be really funny if the mirrors were really as distorted as in the animation at 1:49
I can't wait to see the images 😻
which image
@@SK-pb1fs from this telescope
The Notre Dame Cathedral of our days. A work that, if all goes well, will give us a few years of the finest science
What if the telescope spots another telescope looking back at it? o.o
They have a weapon on board to alleviate that problem. :-/
The #astrology tag made me smile :)
In case this goes wrong, how much time/cost would it take to build another, now that all the engineering hurdles are figured out?
Bookmarking. My prediction would be about $1.2 billion.
Nice video.
this telescope is litrealy so exciting
waiting and hoping all is well will be awesome achievement
Amazing what we can achieve. Quick question though. Now we've built one that's due to be launched. Couldn't we build more the same for far less money and make a super array
NASA was lucky the JWST wasn’t cancelled years ago due to delays and massive cost overruns.
There’s no way anyone is supporting building a second one.
I'm excited for the exoplanet watching through JWST. :)
James webb space telescope benfit will be for all mankind.Thank you very much jwst makers.jwst will be found lot of things.l hope jwst will be win the space.finally definitely it will be happen as I think.
Are there any sample pictures they could've tested JWST with on earth?
Same question, they might have tested its capability from earth itself before launch
@seeker I'm an Industrial Engineer with 25yrs of manufacturing experience. If i was on this project, I'd hire 200 monks to pray & fast 24/7 until JWST goes live (Project Overhead) Hehe
Why are the mirrors hexagonal shaped? Is there a specific reason they went for that shape version square, rectangular, etc?
I don't think there is a particular reason, no. I think they picked random shapes out of a hat and the hexagon was the one most picked.
I can't wait to see this telescope launch and all the discoveries it will make😁😁
My most interesting thing to check
Happy to be alive
Yes, if they'll finnaly set it in the space
ITS FINALLY HAPPENING!!! Launching on Friday!!!
It's so exciting.. it needs to go off without a single hitch.. 👍🏼
HELLO! SIR I AM BIG FAN OF YOU FROM ‘INDIA’ 🇮🇳
Don't bro them if you don't know them
Edit: nice, this is a lot more respectful 👍🏼
How they protect it's golden eye?
Seems to be vulnerable to damage.
Here's the answer from the NASA website:
"We tested beryllium discs for micrometeoroids using test facilities in the US and showed the micrometeoroids have negligible effects on the beryllium. Cryogenic beryllium mirrors have been flown in space exposed to micrometeoroids without problems. The Spitzer Space Telescope, launched in 2003, has a beryllium primary mirror. All of Webb's systems are designed to survive micrometeoroid impacts."
Go JWST..cool...we can do it👌🤩👏👍🧙♂️💕
What I’m curious about, is what these photos will look like, because of the infrared cameras and red shifting and whatnot. Will the photos still be in colour once post-processing is done, or something else?
A Christmas gift to us all
Part of the success of Hubble was owed to it's maintainability. We could go up there and service it because it was close. The JWST is going to be very far away. The JSWT will be 1,000,000 miles away compared to Hubble's 340. Is there any way we'll be able to service the JWST? I just can't see that happening.
On another video covering this as well, an Engineer mentioned they installed these deals where it'll shake the chassis/whatever to kinda get it going or if it gets hung up
Thats ok, Bruce Willis said he would go fix it.
I’ve always wondered if it’s possible to construct an observatory on our moon.
No Man's Sky vibes @ 07:33. Sean knew all along, the crazy ba***rd
Back in 2016, I heard this was going to launch in 2018.

Just hyped for the launch! It been way to long with the continuous delaying! This is going to be revolutionary!
I can't wait for the future where we build a bigger version of this to see other planets' crusts
This telescope will be able to do that most likely
@@dizzlereacts I hope it does and hopefully give more reason to launch satellites into interstellar space and turn the sun into a big gravitational lens.
Also, I disagree, at most we can see the features of a planet but not the crust itself, which could serve as an indicator for life.

IF it all works !!
*Aftwr listening this ,we expect JWST to find our "Edmunds Planet"*
Respect to NASA For creating the unbelievable
The real value of human existence is to understand the existence of our universe, bon voyage JWT.
Launch date shifted to 24th Dec., 7.20am EST. See Magellan TV
How webb telescope testing in earth from nasa explain and detailed video
5 days and than well hold our breathes. Sure hope everything works. This will be such an achievement for humanity. I cant wait to see its first images and info. Rhe questions itll answer and lead us to ask are unknown. Amazing!!!
Does it have fuel source as well 🤔??
So that it can be move it back to earth's orbit if it need upgrades.
JWST has enough fuel for 10 years science ops.
After that, either sending a refueling satellite, or just build a bigger cheaper better telescope, due Starship launch capability.
Lets keep our fingers crossed for a safe journey and successful deployment
Exo planets do bring a smile to my face XD
When I read Golden eye. I read the James Webb as James bond.
I'm just worried about the space debrey , hopefully this stays safe
wow this is actually epic. i really hope it succeeds.
$10BN for a telescope and i'm hungry. i literally don't have anything eatable in refrigerator.
I really hope nothing goes wrong during the launch. this is the best project imo nasa has done after sending preserverance on mars
Oh, you do? 🥺
