👩🏽💻 I'm Dr Becky Smethurst, an astrophysicist at 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.

Just to clear up some confusion of numbers, because DrBecky sometimes mixes them up (it's easy to make this mistake, since the numbers are so similar!)
Earth-Sun distance: ~150 million km
Earth-L1 distance: ~1.5 million km, towards the Sun
Earth-L2 distance: ~1.5 million km, away from the Sun - this is where the James Webb Space Telescope will go
One has to admit, however, that a solar telescope actually _on the surface of the sun_ could give some pretty interesting data. (Assuming it could survive there and transmit.)
@@condorboss3339 How? It wouldn't be able to see anything
i deleted my comment after i saw yours also ;)) i posted almost the same comment :))
@@precursors He only said about "interesting data", not about seeing anything. Probably a lot of data how fast it will burn.
Gigameters! 1 Mm=1000 km (the circumference of the Earth is 40 Mm) and 1 Gm=1000 Mm (1 AU is 150 Gm). Also terameters for the outer Solar System.
I've been waiting for this for ages and I'm not even a scientist.
Yes you are. What is a "scientist"? The word scientist is a general term, used to describe someone who researches and examines various aspects of the physical world in order to attain a better understanding of how things work and function. There are many specializations of 'scientist', and depending on which field of study one chooses to follow, the work can vary greatly. Bottom line here is - even though you might not be a "trained" scientist you have the curiosity that it takes to be one.
Same. At this point I don't even want to get my hopes up that it's finally being launched soon. I won't celebrate until it's up there and running.
me to waiting for the first sights of brown dwarfs or rogue planets roaming near and through the solarsystem - these might be the first object humans can use to get out of the solarsystem as giant selfsufficieant plantesized generation ships -small europe worlds would also do fine (i guess)
Same here! So excited. I just remember the first released photos from Hubble and it was mind blowing. I'm just a space fan, not really knowing that much technical stuff. But the things to be learned from Webb....it's one of those things to stay alive for. Such an exciting time for space fans...Mars, back to the moon, Webb, etc.
Reading Mike Massamino's autobiography "Spaceman" really made me realise just what a wonder the Hubble is. Not just in terms of science, but in terms of making space exciting again and showing the beauty of the universe. And right now more than ever, we need to look up from this world and our self-indulgent angst and doomsaying and be reminded of the wonders out there awaiting discovery, and the great things we can accomplish when we focus. I barely dare to hope for this one; it seems too insanely delicate to possibly work. But just imagine what it could show us....
The two most terrifying things about the entire process is 1. Getting it into space, and 2. Unfolding it.
3. First Light, making sure there is not some mistake in the optics, like Hubble
4. Hoping the reaction wheels are better than the ones in Kepler
5. Hoping the comms don't have some major problem like Cassini or Galileo
etc
0. Transporting it trough the middle americas hostile states without beeing captured by large drug qartels.
Getting it into space is easy. Unfolding it is the tricky part.
3. Finding the aliens
Is it possible to have gas pressure without a container?
13:00 That assembled mirror is so beautiful. Not the gold, that's happenstance. I mean looking at how large it is, and just how smooth that thing is. And it's in 18 panels. The total level of craftsmanship involved in the entire telescope. Just the best of the best people from around the world making this stuff. Pushing that envelope. Really exciting stuff!
The gold is actually beryllium.
It really doesnt matter how long it takes to get it right, getting it right is what matters. Some things you simply have to be patient and let it be when it will be. This is a HUGE step in our advancement, we absolutely must get this right.
I remember being a young man excited about hubble.
I remember being a young man excited about the James Webb telescope...
Me too, that whole shuttle mission to fix it was super interesting...
I remember Adidas (w/the maroon stripes) costing $5 (or so my mom told me...)
I’m in your shoes now with James Webb ☮️
@@Jah_Rastafari_ORIG Adidas? Adidas? What Adidas? Two choices were Keds and Converse. Your mom is young.
I can't imagine the anxiety of the entire team. Must be atrocious, working on something for so long with so many thing that can go wrong. I really hope they will succeed.
The range safety officer who is forced to push the self destruct button on this mission might be traumatized for life. Worst job in the world.
The Arianne currently has fairing problems which could damage the sunshield.
I no longer care if it works. It's so small, so outdated, so inflexible, so limited and so expensive. In 2 years starship will have 100 tonnes to LEO. They should give up on this origami monstrosity and design something 30-40 metres diameter that can be assembled by humans at the ISS, fully tested and then sent off with 100 tonnes of fuel on board, and a plan to fly itself back to the ISS every few years for upgrades. That would probably cost less than the expendable launch vehicle they're going to use up sending this waste of time. (€150 million for a launch).
@@gasdive Only Elon Musk fan boys have the capacity to drop comments this stupid. Do you really think these ideas have not been considered by the thousands of scientists working on this project? A single look at the FAQ about the James Webb on the NASA website would have answered all of them. They specifically have a section on a) why they are using Arianne b) why assembly at the ISS is infeasible and c) why retrieval of the telescope to LEO for maintenance / upgrades is also infeasible. But let me give you an overview:
a) For various reasons most of the parts of the James Webb are manufactured in the US (e.g. restrictions for technologies with potential military applications etc.). In exchange for all this manufacturing in the US, ESA provides the launch vehicle and covers the associated costs, meaning the total cost of the launch for NASA is exactly $0. I highly doubt SpaceX can launch anything for $0. In my opinion this is a very good deal for the US considering how many high tech jobs are created by this deal.
b) Simple, the ISS does not have the capability of assembling something as complex as a telescope. In addition, the orbit in which the ISS is has lots of tiny space debris that would potentially damage the telescope. Also, building something that would be able to survive a second rocket launch once assembled is a whole other challenge. Once assembled, a huge telescope would be very susceptible to the g-forces and vibration caused by a rocket launch - even if its not in Earth's atmosphere.
c) I think this was already answered by part b) but just to repeat: sending the telescope back to LEO would likely damage it through vibration, g-forces, space debris etc. The ISS cannot do this kind of maintenance and even if it could it would be exorbitantly expensive and simply not worth it. After all, eventually you would have to replace the telescope anyways and at that point you will wish that you had saved the billions on the upgrades and instead invested it in a single mission for a new telescope.
@@orbital1337 "do you really think these ideas have not been considered by the thousands of scientists working on this project"
Straw man. But let's look at your rebuttal of the argument I didn't make. Generally speaking, the workers in a multi billion dollar project don't get to decide that they're in a technological dead end and pull the pin. There may be hundreds who think it's a waste of time and money. Saying your bosses are wasting everyone's time and money is not however, a career advancing move for anyone.
"for various reasons most of the parts... are manufactured in the US... military... restrictions"
Perfectly circular argument. Webb is made in the USA, so it has to be launched this way and its made in the US because its launched this way.
Spending an extra 8 billion dollars so that you can get a free ride rather than pay for say 10 falcon 9 launches at 60 million each is not a valid reason nor is it without cost as you seem to think.
"assembly at the ISS is infeasible" circular argument again. Its designed to unfold so we can't assemble it by hand because it's designed to unfold. I've assembled a lot of stuff underwater, which is like zero G, but with added difficulty. The idea that humans can assemble mirrors on the ground where they weigh tonnes, but not in space is literally absurd. The idea that an automated origami can do things humans can't; also absurd.
"In addition the orbit where ISS is has lots of tiny space debris" no, it doesn't. It's in a spot where small debris deorbits quickly. That's why the ISS was put there and why it needs regular boosts. It's one of the lowest debris point. Not only that, but erecting a Styrofoam box or similar around the worksite will completely protect it. Not only that, but there are plenty of micrometeors in its final location where it will spend decades rather than weeks. If it can't survive that, then it can't survive in service.
"survive a second rocket... g-forces"
It has to run the rocket while assembled to stay on station. That's what it does already. The spot they're putting it isn't stable. If it can't survive a rocket running, it can't survive at all.
"back to LEO... not worth it"
You're probably right because it would be so cheap to build and put in space, even now with only the Falcon 9, it's probably better to build a new one. However, in 5 years time, a Starship based in situ service mission would be easy and cheap.
They've spent billions and decades down this rabbit hole. Even if we didn't wait for starship that could launch the whole telescope and serve as a work camp during assembly for 50 million, F9 could do this now for under 600 million and have it all in orbit in 50 days (the current cadence is every 5 days). Guys in suits could clip it together like lego and the fine adjustments done with servos from the ground. The first Hubble service mission managed a *vastly* more complex task. Saying modern astronauts couldn't do it is a combination of absurd and insulting.
I remember this being my intro Astrophysics research project about 12 or 13 years ago. So awesome seeing this come to fruition and scheduled for launch in November 2021!
it slid a few more times, but launched early on christmas day 2021, USA eastern time about 0730 after around 7 years of delays. at this writing it has left earth orbit and on the way to L2 Lagrange, unpacking itself in transit.
Big thanks to all the team.and scientists working on the scope, can't wait for initial images to come through 🔎👍
As a member of the "public" I would like to correct you and say there is much excitement. I was a young man when Hubble was launched and now a middle aged man that can't wait to see the images. I just pray all goes well and works.
Me tooooo
I remember 3rd grade and breaking out the World Book Encyclopedias for a review of the planets. It was the mid 70s, before Mars Viking and the launch of the Explorer probes, long before Hubble. All the planets were grainy ground-based telescopic images. What we have (already) discovered in under 50 years is astounding.
I'm 45! I've been waiting since 2000!!! I'm SO EXCITED 😁 😆 🤗
Wow, that was the best overview I've seen. Now I'm excited about it! Thanks.
It's hard to imagine the amount of work, time and engagement that has gone into this project, by so many people.
I SO hope everything will go as planned. ❤
Hope the rocket explodes then you may realize you need better rocket's first
It is pretty hard to imagine how they spent 8.8 billion dollars. It must have been nice though.
@@1pcfred You're into longtime budgets, are you, Paul?
Actually I doubt it.
@@JohnJohansen2 I am into being truthful. Don't tell me something is only going to cost 438 million and then charge me 8.8 billion! That is totally unacceptable.
@@1pcfred Place. Dive back into your hole in the ground! 😎
I'm not getting my hopes up until it's successfully launched. I don't even want to think about it exploding on takeoff
Me neither. But I do...
I'm more worried about the radiation shield tearing in space
Ariane 5 has a great record, I just hope it continues.
Don't want to imagine Europe killing the JWST 😐
I believe in the James Webb Telescope like I believe in Avatar 2 and 3...
"They" never thought "they" would have to push the "narrative" for this long..
The elites thought they would have absolute control by now, but God has other plans :):)
It is bound to go wrong.. too much frayed nerves and feature creep.
Dr. Becky, this video was amazing!!! Thank you for that! I waited for an explainer video like that.
Absolutely love your passion and your concise information about the science behind the Webb. Watched the whole thing and understood every bit of it. Growing up always wanted to be a astrophysicist. Life had different plans but feel so lucky to be alive in this age of instant reach, and access for really advance science from scientists like you. Thanks for all you do!
Did you _really_ have to say that Hubble has been up there for 31 years? I feel quite old enough as it is, thank you very much.

I've been waiting for the JWST my entire adult life. It's amazing to think that the original launch year was 2007 and now it's oct 2021 and the origninal budget was $500 million and now it's ~$10 billion. I really hope it doesn't fail, there's so much that can go wrong.
Kind of reminds me of Sheldon from the Big Bang Theory trying to get his project funded...maybe he had the right idea😄.
@@villipend I have somehow never watched the big bang theory
Check out the new Vogel #3 reactor in Georgia, USA if this is breaking your heart. Heck, my (formerly great) State could have literally funded single-handed the JWST **AND** launched and developed Starlink (© Elon Musk 😂) and GIVEN FOR FREE internet to the developing world... I bet we coulda even gotten internet to the kids here who don’t have access... plus given every child one free year of college... it’s all a scam. Worst part for us?? After all the expense of building the “new” nuclear plant?? The cheapest thing by far residents of GA can do is BURY the outdated from the start junk pile. This is a testament to society’s priorities... They haven’t been with people or science your whole life. We enrich the wealthy. We give government research away to Elon, Apple and Big Pharma. We give our labor away and fund science only to enrich the wealthy with patents derived from public research. Good luck. jom
Don't even think about it!!! If the rocket fails... Damn.
@Ian W I wouldn't call 25 years of work and $10 billion turning into a useless piece of junk hilarious.
THANKS SO MUCH FOR THIS TOUR!!
You're excellent at getting people excited about science. Keep up the great work.
I had the privilege of spending 2 hours watching the sunset in Hawaii, and chatting with Dr. Mather about Webb 2 years ago.
And you'll notice it's still not up in space.
Don't get stingy on us, what did you talk about?
@@phapnui mostly about how it's not up in space yet.
I went to the international space station but I didn't want to boast so I didn't mention it. 🙂
Cute date
As much as I look forward to JWST's hyporthetical launch someday if the delays stop, and I understand the scientific value of observing in infrared, I'm sad it's not optical. There's something enchanting about Hubble's optical wavelength images being "what I would really see" and I'd love for that enchantment scaled up to the larger mirror size and resolution - not to mention being made with shiny new electronics.
The Chinese are launching a much bigger than Hubble optical telescope as part of their new space station with brand new digital technology. I'm really excited about that one.
I dig where you're coming from but I'd like to share my experience with imaging in IR wavelengths as a suburban astrophotographer in the southernmost borough of NYC. Basically, I have significant sources of light pollution on three sides. One thing I "discovered" is that I can capture really clear long-exposure images of nebulae. It works by virtue of blocking nearly all of the light pollution related wavelengths.
For example, the California nebulae shows up in black and white but the detail is stunning. Since I'm using an "Astronik Pro Planet 742" bandpass filter, I'm seeing light wavelengths at and above 742nm. This data can be accurately processed into red (black and red instead of black and white). From there, if the image can be combined with images captured with other filters. Usually with narrowband filters (Ha, Oiii, and/or Sii) but I also use RGB filters, however they are severely affected by light pollution and seeing conditions.
I usually treat Ha like it's red during processing, Oii a bluish-green, and Sii is a deeper red. I've barely used the last one so far. My point, JWST data could be combined with other data from different filters on other telescopes. The JWST IR data would make one helluva luminance channel.

@@DJRonnieG I get how all that works, and I know that's basically what we're doing to get all the spectacular space images anyway. Even in optical wavelengths the images are RGB composites made with filters. But that's just the thing. What makes the image magical for me is that my mark 1 human eyeball would perceive it in precisely that way if I could see that far. As soon as the image has a legend explaining that it's a composite of invisible wavelengths with red representing this and blue representing that... I don't see a beautiful photo of nature anymore, just a lifeless science diagram. Useful, maybe a little pretty, but not a soul-stirring taste of the wonders of the univers.
Optical wavelengths are overrated.. you can get amazing images with infrared light as well, and either ways you would never be able to see that with your eyes so.. I don't see why it's any special
Thanks for the happy, bubbly and accurate presentation. Always a pleasure to watch!
I've been waiting for this about a decade. I can't wait anymore!! LETS GO!! 🌌🔭
Until it's actually been launched and shown to work I'm tempering my expectations, I still remember what happened with Hubble.
Could be worse, like the first Arianne 5 launch, and the Cluster mission : -) Watched that one live back in the day, one of the guys in the Dept was relying on the data for his PhD.... oh dear.
I have a feeling Webb will fail. If it works it is going to be something else though. If it works like it should we will see things never seen before. But when are we ever allowed to see that sort of thing?
@@engineeredlifeform shit, I feel that guy's pain
Hubble is Sofia. Space doesn't exist.
There have been dozens of space telescopes launched over the years covering a range of wavelengths. Why be jaded by one hiccup that was ultimately fixed?
Omg finally a video about why James Webb telescope should be hyped! I got so tired of explaining it to each one of my friends now I can just send them the link!!
This is definitely an exciting time! I learned about the JWST as part of course I'm doing. And I definitely appreciate the enthusiastic presentation!
This is so exciting! A new dawn for astrophysics and astronomy.

Nope. I'm sure won't be launched until 2085 at this point... we will all be dead...
I hope from all my heart it will be a success. Hardly can’t wait
All the stars will be extinct by the time the jwst gets launched. Now it's slated for December. In a month they'll push it back to march 2022.. then may.. then october.. then December.. then march of 2023... see a pattern?
There will need to be a James Webb recycling center where we can send our soon-to-be-obsolete astrophysics textbooks.
Been eagerly awaiting this masterpiece! From the first time I heard of the plan to build this and where it would be deployed. This will be absolutely awesome!!! Can not wait.
I've been following this since it was the "Next Generation Space Telescope." My brother in law was a TRW engineer and started on it at request for proposals. Hes retired now, but I also know a couple other engineers on the project, so I got to go see it in March, as they were folding the sunshade for the last time.

American me: "what's a 'bin bag'?" seconds later: "oh, a trash bag, gotcha"
Thanks. Now I won't google it to make sure. It took me more like 2 minutes to get there while being sure to not missing anything the Dr. said. I heard it as bimbang. My internal language processor got it to bimbag in a couple a couple seconds. Then some higher lever processing reminded me that the UK has garbage can as dust bin. Then bim might be bin. Click. bin bag.
(I was born in 1946.) Before I had some hearing loss myself, I thought that poor hearing was a lack of perceived distinctness in sounds. In my case, everything sounds perfectly clear. It is not indistinct. I hear almost everything the same as if I had no loss. It is only when something makes no sense that I can tell I have not heard correctly. At first I was baffled at people using obviously wrong words. An interesting side to this is that new accents disappear to me after hearing them for a minute or so. I just thought I'd say that.
The older I am, the stranger it seems that while you are young you approach everything as if they have always been pretty much like they are now, until some gap occurred a vastly long time ago, some time that only professional historians know through research. Garbage bags still seem a little wrong to me. You buy a thing just to have a thing to throw something away in? Why not just throw the thing away?
When I was a child, people threw things away in a garbage can. Actually two, which by law had to be separated into garbage and rubbish, and labeled in a permanent way, such as buying cans labeled. The garbage can, at least, had to be on an elevated stand of a designated height, but mostly both cans were on the same stand. The cans had to be metal and in undamaged condition. The garbage can, by regulation, had to be kept clean, but maggots, flies, slime and stench were sufficient enforcement. Nothing came in a plastic bag because plastic bags were non-existent. (Cellophane is admittedly plastic-like, although fragile.) The only reason there was plastic anything were junk toys from Japan that kids would demolish within a week anyway, plastic or not. An evolution in plastic happened over decades. Plastic items that were practically indestructible began to exist, but cost a premium over traditional versions. Then plastic versions came to be the least expensive. Only people foolish with their more money used the first trash can liners. Saturation ads showed how a plastic bag inside a can and over the lip kept the can tidy. Rather than cleaning out the can periodically, you could periodically dispose of the bag by just tying up the bag inside the can. The garbage man left the bag in place if left wrapped around the can. Then, cities passed ordinances requiring the use of trash can liners and forbidding the use of the bags themselves outside of a can, as people began doing. Then cities allowed trash bags if they were over a certain thickness and were tied closed.

I’m squirming with excitement at what the JWST might uncover. I’m especially interested in your number 3. Makes me want to major in astro-physics.
I had to come back to this video after the launch and watching you watch the launch! Nobody expected a Christmas Day launch but wow that last image of the sun reflecting off the JWST solar panels, just epic.
Wow, discovered this chann few weeks ago. Your excitment is contagious. Keep it going. Nice job, love it 😉🙏
Welcome!
James Webb arrives at L2. GAIA: "Who are you? What are you doing here?" JW: "I'm James. Nice to meet you" GAIA: "Butt out buddy. This is my patch" James:😥
James Webb is probably the biggest thing Ive known for around 5 years
Trust me Im HYPED
A worthy successor to Hubble TBH
It's not a successor to Hubble.
It's a completely different thing.
Hubble let's us see lots of things in space basically the same as what we'd see with out own eyes if we were close enough.
JWST will be even better for doing actual science, but not a single picture will be "real", because they have to be false color images since it doesn't detect visible light.
@@lordgarion514 it's not a successor to Hubble... Hubble made it to space...JWST won't. s
@@rustythecrown9317
Oh be quite. Lol
Really though, NASA just underestimated the scale of the project, by several orders of magnitude. And how could they know how much they didn't know?
But if you look up just what they have accomplished, it's staggering compared to private industry. NASA really has done a LOT for the amount of time they've been working on it.
It's taking so long because they're was a lot to be done, not because NASA has been having "extra" trouble with something, or dragging their feet.
After the blue LED laser was invented, the Blu-Ray took 11 years to invent.
NASA invented half a dozen entirely new technologies in 20 years......
@@lordgarion514 NASA may have invented more new technologies , but getting Webb into orbit wasn't one of them. Murcans used american measurements and the ESA used the proper measurements... It's Hubble all over again.
@@rustythecrown9317
Umm, NASA is fully metric, and has been for some time.
But about that "proper" comment.....
How does that "proper" measurement help the Europeans make enough money to support themselves without Americans having to pay for most of the EU defense?
Metric is indeed better for science. But only because the 10's thing makes a lot of things easier to do in your head.
It's no more accurate, and it doesn't help you folks have a better economy.
After Europeans use their better metric system, AND their supposed better education system, to be able to support themselves, without billions in welfare from America, then they can claim it's better.
Me at 50 waiting excitedly for the James Webb telescope!! Me at 90 still waiting for it.
I believe in the James Webb Telescope like I believe in Avatar 2 and 3...
"They" never thought "they" would have to push the "narrative" for this long..
The elites thought they would have absolute control by now, but God has other plans :):)
@@frankoramerez4536 you mean God wants the scientists to fail?
I started working on JWST in 2010. Anxious to see it be successful after the delays.
I wish I had grandchildren, so I could teach them to tell their grandchildren to look forward to the JWST.
Still not long enough 😂
I have 12 grandchildren......trust me they don't listen to me anyhow....and most of them think I am a nut or a "crazy old man" who doesn't know what he is talking about!! I was talking to my one grand daughter who is just 15 years old now, and told her that "in your lifetime you will see something I could never see" and explained to her that Halley's Comet will return when she is 55 years old, and she just looked at me with a blank expression!!
It didn't register in her, that I was telling her of a "future event" that never would happen again IN MY LIFETIME!! You see I have heart problems and I am already 56 years old, so in roughly 40 years (from the day I write this) Halley will return and I will probably have been dead for many years by the point!! And SHE will be nearly MY AGE then!!
@@gregbenwell6173 That's kind of messed up, why would she treat her own grandfather like that? I used to listen my grandfather tell me things about the past, present and future, because he was an insight to it all and his memories told a story unlike any other book on this earth.The crazy thing is, if she didn't believe you she could have just googled it and learned more about it,but all you got was a blank expression. I'm sure one day she will see it for herself and remember the moment you talked about it.
It reminds me of the old proverb: "A society grows great when old men plant trees in whose shade they know they shall never sit"
@@gregbenwell6173 I remember comet Haley, what a disappointment. Virtually invisible to the naked eye. We bought a cheap telescope from K-Mart (etc.) and you clearly it see it, but not impressive at all. About 5 or 10 years later though was VERY impressive comet. I want to say Hale-Bopp but that is the one that crashed into Jupiter right? This one was huge! You couldn't miss it (in America anyway) no matter how bad the light polution. It seemed to hover in the night sky for about a week. I don't know the actual optical size, but it *seemed* to be almost half the size of the full moon. Wish I had a digital camera back then, or enough foresight to photograph it with a conventional camera. I also remember it had a slight greenish tint, and reminded me of the movie _Maximum_Overdrive_ ... fortunately the machines didn't take over the world! Anybody remember that comet's name?
I'm looking forward to the evening when I can see amazing pictures from the JWST come in, after having just completed Half Life 3, and then settling down to read The Winds of Winter.
WofW is coming out 2042

@@YassinElMohtadi Those two are probably more likely than those preceding them lmao
What you did, I see it there.
The Gleam in your eye when you talk about the Stars and the brightness in your voice you can tell that you are genuinely excited about this new telescope and now you have me as a new subscriber
I just watched another video about the delays etc of JWST, and this one came up after.. So here I am.
You are an absolute treasure! Smart and excited about the JWST - had me smiling most of the video. The bloopers are adorable. Thank you very much! Now I'm off to watch more of your videos :)
Ha, I went to uni with Sarah. Well done her!
Not sure who you are from your username but thanks and 👋
@@skendrew ah well I’ve been rumbled now! I hope I’m getting the right person! It’s been a while... You played in UCL Opera?
@@JazzGuitarScrapbook I did indeed! :-)
@@skendrew aha! It' s Christian from the choir... anyway great to see you doing so well! Exciting times in the field (or so it seems.)
Oh, the untangled Webb we weave when first we practice to perceive. (With apologies to Mr. Shakespeare for mangling his epic line.)
Ok I can stop reading now, you win this comment section!
Of course, they'll untangle it once it gets out of the rocket.
Love it!
Love your videos! I'm just a hobbyist with an avid interest in astronomy and I'm thankful running across this because I almost forgot the Webb is going to be launched this year. Great interview with Dr. Kendrew, I have great respect for her and the rest of everyone involved pulling off something of this magnitude, it's important work. The more we learn about our universe, the more we will learn about ourselves and learn how to take care of each other and our own planet - at least that is the plan right. And where can I get that Webb mirror T-shirt Dr. Kendrew is wearing because that looks awesome!
Great info, thanks👍
22:43 "Infra-Webb" is actually really spot on
Love your content!!! Thank you for making it!!
I've been following the JW Telescope and cannot wait for the launch!!! I'm right with you crossing my fingers!!!
Dr. Becky you ROCK!!! I came across you by accident just two days ago. Usually on CZcams I stick to politics (Noam Chomsky, Cornell West, etc.). But there, for some reason, I saw your "thumbnail" (as I believe it is called). The rest is history. I'm hooked! Thank you for you intellect, your boundless curiosity, and, most of all, your intense enthusiasm! Onward and upward, my friend! Keep up the good work!!!
I'm a 72 year old retired layperson that has enjoyed following the James Webb Space program for years now. Appreciate Dr. Becky's excitement/enthusiasm for this program along with her excellent description of this program for individuals like myself. Keep the videos coming. Great educational lessons for all ages.
What if it explodes
@@howtodoit4204 Just a chance we have to take in order to explore the Universe.
Just 15 more years, guys! This time we promise!
That's right, it will launch in just 20 more years. You'll see, 30 years from now on the launch pad! You won't be the one laughing when it gets to L2 in 2055 right on schedule.
Okay, here's another $10 billion funding for the foreseeable future. Oh by the way, I couldn't help but notice that you started driving to the lab in a gold plated McLaren F1 ...
It should take as long as it needs to. It's far too important to not get right! You should never rush a project like this even if it ends up costing 20X initial estimates
@@Cara.314 The folks who built the pyramids thought the same thing.
@@Cara.314 It literally has cost 20x the initial estimates lol. Budgeted at 500 million and it has now spent 10 billion.
I just hope when my great grandson reaches my age he'll be able to make it to the launch. ;)
Wow thank you for your explanation, for some reason i understood your version on explaining things then other youtubers thanks 😊
Dear Dr Becky, 48 UK based carpenter and ice just stumbled across your channel and I’m finding you extremely informative and a breath of fresh air with plenty of energy and enthusiasm within your field, just a great way to absorb huge vast quantities of data whilst I’m working on a decking project next to the river Avon in Worcestershire, ha you wouldn’t happen to be a Fran fan would you?
😊
Imagine the kind of things we could hope to see (like the first time we took a deep field) 😳
Seeing inside dust clouds is like Superman X-ray vision.
Yeah, following the Hubble ultra-deep field, JWST will be like "hold my beer".
I am looking forward and hoping to hear that they can learn more about th expansion.
Planet 9 and rogue planets
Maybe, when JWST finally goes online, it'll be so good that it can look back in time ... to see its own inception.
Yeah. Imagine looking out really far and seeing but a reflection of yourself silently staring back…,
Technically I think it would be possible if there where some kind of structure that reflects light back from where it comes from, kind of like a giant space mirror 🤔 or maybe some weird gravitationa lense that bends ligt by 180 degrees.. not sure if anythi g like this is possible, but that would be so cool to be able to see earth on the past
I dont think it work like that
5:50 - fingers crossed - wow, that's a skill!
I'm more excited for this than any other science out there right now. Let's just hope everything goes smooth w the launch/set up 😬
I don't really understand this thing completely but if Dr. Becky says I should be hyped, then I will!
hi
👋
I really don't know anything much about this type of stuff. I mean being a songwriter, musician, vocalist and a body builder I mostly look for those types of things to watch or related things, but youtube started adding different videos like this and others to my page. So I watched a few of these here, and even though I found Dr. Becky to be very entertaining, knowledgeable and informative, I just like listening to the way she talks. I think she could have a video on here of her just reading a book and I'd watch it so I could listen to it. You're awesome Dr. Becky.
Excellent episode.
With such a large thin sun shield, do we expect to see small pin holes from space dust and micro meteors over time?
I asked an engineer at Ames about just that type of pitting of the mirrors and he said, nah we're good.
With that large of a sunshield, would it be a solar sail away and needs constant correction.
@@bombappetit exactly why they'd park it at a Lagrange point, that thing ain't moving in either direction anytime soon
Dr. Becky, might JFW looking into infrared then more accurately determine the age and size of the universe?
Ig It would have to see in microwaves to do that
I'm so excited to see the images that come back.. I'm setting my expectations to jawdropping. 😀
Great Video! I learned a lot
JWST will be launched. I have faith. It's just that first we have to wait for Duke Nukem 4, and then Half-Life 3. Then it will launch. Cross my heart.
Speaking of Hubble, I would be curious to learn what has changed from when Hubble was tested pre-launch and now with the Webb being tested pre-launch. Are secondary groups being asked to verify test procedures? Has optical testing changed a lot? If you could shed any light on this subject I think it would make for a good followup video.
As always, we appreciate the time and effort you spend to bring us these videos and we thank you.
JWST was absolutely pre-launch tested.
well apparently on the JWST, the alignment gyros have been mostly re-designed. on the Hubble and Kepler, they had a tendency to fail before other arguably-dependent-systems did.
I'm incredibly excited about this. For myself and my kid who's 6. I want more than anything for humanity to come together for us all to explore space.
Another great video, Becky! Thank you!
