Yeah, I think it´s brilliant, that back-and forth with the editor makes some of the more complex explanations so much more relatable and easier to follow.
two amazing things that no one mentions: the flap on the back of the telescope is a small solar sail, its going to be used to help rotate the telescope to reduce the saturation of the gyros. another thing is that its so freaking cold on the shade side of the telescope, that you actually can use superconductors, and that is exactly what they did, some components are made of superconductors to reduce weight.
Yeah, it's not much but ANY form of thrust they can get saves fuel. The recent loss of the 40 Starlink satellites might be of interest to you, they use wires of some kind they deploy that interacts with the magnetic field along with thrusters to move the ship, leveraging the earths own magnetic field for orientation changes, it's damn near magical. They lost the satellites because the atmosphere swells when it's hit by a solar ejection/wind and their system would no longer work because of too much drag. The thrust they get out is pitiful, but it's 'free''
@@millicentduke6652 generally superconductors aren't practical "close" to the sun (massive quotations around close). Howeger when the ship needs to be incredibly cold anyways it's the natural fit. Since superconductors produce less heat then normal wires actually.
My 5 year old daughter, and I, love watching your videos! She says she wants to be a scientist when she grows up - so thank you for being an inspiration to her! Hope your eye feels better soon. :)
My uncle got me into science when I was a teenager. He was very excited about this project for over a decade. He said "seeing what happens" in space science was one of his reasons for living. Unfortunately, he passed away last summer and I was often reminded of how much he would have loved to see the images that will be coming out later this year.
I relate so hard, after this telescope, there are plans to launch LUVIOR telescope, which can see in ultraviolet as well. This planned telescope have much much larger mirrors and can see more far and in much more detail. But, by the time that will be launched I will become old. Knowing this fact hurts.
Condolences. Know that your uncle loved every second of getting you excited about science. One of the joys in my life is passing along to my niece what little scientific knowledge I have, and experiencing and learning with her. I hope her memories with me will be as fond as yours with your uncle.
It's like sitting in on a conversation with a professor and student. Very cool format to learn and I like the parts where the camera is angled so it's like you are sitting at the table with them.
Gives me hope. As in, those boring conversations where I go on and on and I see the life slowly drain from the eyes of my conversant over the course of an hour can be redeemed with good editing!
@@tbird-z1r Honestly, Her editor is hitting on her. Not that there's anything wrong. Pretending to be interested in physics stuff, asking random questions just to get her excited and spend time with her and talking to her for hours. Kind of obvious to be honest. Anyone that is interested in this kind of stuff is at least good with the basics or curious enough to google it themselves.
There's an old XKCD comic that explains how impossible it is to know EVERYTHING so if someone says they don't know something, you shouldn't criticize them but rather get excited that you have the opportunity to introduce them to something new and cool. The best part of this channel is that Dianna takes this to heart, and it is wonderful.
I absolutely LOVE the Physics Girl. She's hilarious, plus she gets so excited explaining the science and engineering of the JWST that she makes the learning fun and interesting. Thank You!!!
You clearly aren't someone who likes to learn if you need someone to make it fun. You're the problem with our education system, students expect to be entertained not educated.
LOVE your channel. IF i had to do it over again, I'd major in physics. LOVE seeing a young woman this intelligent and educated setting a phenomenal example for young girls everywhere. Thanks.
This video was perfectly executed! Fast paced enough to keep your attention but detailed enough that nothing important was left out. Awesome job girl 💪
Great amount info w/just as much personality. I feel bad about that surfboard incident. A slight imperfection; when regarding deodorant/best not to invoke the"southern hemisphere"(Australia). It was good 4 a laff i guess.
Disagree. I don't like the format. Having a fake guided QnA with a guy who doesn't even know the right questions to ask ends up explaining/communicating meaningless little factoids (I couldn't care less how far the JWST is scaled down to a random coin), while the remainder of the video doesn't go beyond repeating what dozens of other science communicators already explained ad nauseam. Tell me something of relevance I haven't heard yet and you've earned yourself a subscription. Otherwise there's no point because you're just regurgitating the same thing people already talked about weeks before you.
Except right from the beginning: "NASA launched the most powerful telescope ever made" is, of course, incorrect. JWST is nowhere near the most powerful telescope ever made.
@@robertakerman3570 It's not luck, I'm just subscribed to the right people at which point other subscriptions become redundant. This video was a recommendation.
Oh, no! She forgot her elements. Our sweet Dianna got hit in the head so hard some of the periodic table fell out! 😄 I hope you get your memory back quickly, Dianna. Get well soon. 🙏❤
I just discovered your channel and love it! I postdocked at MIT almost 50 years ago. I loved the environment. Everyone there was interested in what I was doing making it the most fertile environment for learning that I have enjoyed. Your enthusiasm, brilliant mind, and quick wit make me feel like I am back at MIT. I have already come to understand things I have puzzled about for years from watching just a few of your videos. I look forward to learning a lot more.
Seeing somebody let their passion and excitement shine so brightly while teaching - especially in the sciences - is so wonderful. Fantastic video, Dianna (and team)!
Aww. I hope your eye gets better! You are such a strong wise woman!💖💖💖💖👏🏽👏🏽👏🏽 As a 12 year old learning about space from you and my science teacher learning is interesting.
Wow! Dianna is an amazing science educator!!sad that she had a sports accident but luckily not too bad… Exciting episode indeed!! I also watched an episode specifically about the orbit of JWST however defined around the Lagrange point I suppose on Launch Pad Astronomy - I hope you find it interesting to watch if you do in addition to everything Dianna stars in etc - I must say for everyone including us adults however defined I feel things like Dianna’s NASA episodes are amazing to take our minds away from other mundane and also difficult daily things like Covid precautions etc - Thanks again Dianna & all!🔭🔭🔭🔭🔭🎬♾☮️💟🌈😻🥰😘🤯🗽
PG: I absolutely LOVE watching your videos. Had you been my science teacher I may have moved in a different direction. You make topics interesting and relatable. Love your enthusiasm and intellect!
I love how simply you describe very complex things. While I've read and watched a lot about JWST, the Fanta explanation for finding life made more sense than anything I've seen so far.
Really looking forward to seeing images from JWST. Hope it finds stuff that nobody is even expecting, and it takes us further into a whole new era of interstellar, intergalactic awareness.
That's probably the most exciting thing about JWST for me, it's not the things that we're expecting that will be interesting, it's all the new things we'll see that we weren't expecting that will be the most interesting. This is how science progresses. Not with a Eureka!"" moment but with "That's odd"
Woke up, went surfing. That sounds like paradise! And now to the substance: You made me understand the progress of the James-Webb-Telescope. Thank you so much! That literally will be the first thing I will explain to my 6th and 8th graders in school next week.
First time watcher-now subscriber. This was one of the best videos I’ve seen on JWST and just science in general. I love your intelligence and easy going nature in explaining things you’re passionate about. Stay blessed and please watch out for the flying surf boards. You were very fortunate.
You should also check out Astrum and SEA they also do great videos with great graphics. They both did several videos on JWST I think you'd find interesting.
Levi is such a great sounding board for you. He knows little enough about your science that he asks great questions and has such honest answers when you ask him questions. Yet he appreciates and learns as you go. Great teamwork on your videos when you interact with him.
I can remember being in awe after seeing some of the earliest images, of gorgeous stellar nurseries, produced by the *Hubble Telescope* (after the mirror was fixed & colour-corrected). Several years further on, *The Hubble Deep Field Image* was developed (from a composite of 342 images) & I was utterly blown away with the huge number of entire *Galaxies* seen in such an infinitesimally small section of the sky _(2.4 arcminutes a side / 24-millionth of the whole sky / or the area of a freakin' tennis ball @ 100 meters away!)_ - implying a truly staggering quantity of *Galaxies* in *The Known Universe.* Now, decades later, I get to see the amazing things that the *James Webb Infrared Telescope* will show of the early days of *Stellarsynthesis,* potentially habitable worlds & even *Infrared* views of the center of *The Milky Way,* without the obscuring dust blocking it - perhaps even high-resolution images of *Sagitarius A**
Did you know that with a small 80mm to 102mm (3 to 4 inch) telescope by stacking pictures you can get awesome big telescope like pictures? There are apps for stacking too. I use a 150mm (6 inch) to star gaze, but use a 102mm set up for astrophotography.
Was a Reliability Engineer on HST development for several years including initial deployment and also repair/maintenance missions, such a success story over our failure modeling, predictions, mission life, etc., super cool to have worked on the HST mission - With respect to JWST, mega exciting but wow $10 Billion is quite the expenditure based on original estimates, schedule, etc. - Anyway, the science implications and potential discoveries I assume are going to be quite enlightening - Mission success so far with launch, deployment, and calibration are truly incredible based on spacecraft complexity and everything functioning so far as designed - It's going to get interesting for sure... \m/
So many amazing and straightforward answers to questions about how humanity's newest eye is going to look at the universe. L4/L5 is stable so there is random space junk there, so we sent our telescope to L2. Such a great explanation, Dianna!
One thing I learned about that I thought was super cool was that we could also look for technosignatures. On top of the elements of biological processes, if there were a civilization on a distant planet, we could also potentially see silicon signatures like we do here on Earth which would be a much more definitive sign of advanced life or civilization on a planet, in concert with the appropriate biosignatures of course.
Interesting thought. Imagine life in the universe developed everywhere in about the same time. Right now there would be millions of civs that are only a few thousand years more or less far developed as we are. What would be the time that the techno signatures needed to travel between two civs so that one 'sees' the other? If all civs survive, will there be an era of techno signature flooding in the far future?
Until we can somehow bridge a gap of millenia, I'm not overhype for finding intelligent life on a planet in a star system shining over 2k LY distant. Like, so what? What are we gonna do? The odds of a civilisation lasting and still remaining intact by the Time it took to reach it, I reckon, are slim. Then figure in the time it takes their EM telltale to reach our solar system, at Light speed its 2k years, so at minimum a span of 4k years from discovery to first contact give or take turnaround time (getting the journey craft put together etc). Plenty of time for Earth to forget, or its own civilisation to suffer a system collapse, or destroy itself, and all that negative stuff... We're talking a seriously longgg lead time here.
@@santyclause8034 cant tell if you enjoy being pessimistic, but the entire thought of there being other life out there than just us is amazing in itself.....It's well known that special relativity and the standard model are both wrong (or at least incomplete), and the majority of us already understand that there is an unfathomable amount of space between us and other celestial objects.... It literally doesnt change anything, and wont stop us from trying anyways. You have no way of knowing that in future we wont solve this issue. Humans have been able to accomplish anything we've set our mind to so far. We live on the edge of AI - Human symbiosis, there's no telling what we will do.
But we still wouldn't be able to detect it anyways. Cause light reaches us faster than any other signals we can read like the technosignatures or radio waves n such. N so if by the time we see the light from where whichever planet we are aimed n looking at,we'd be seeing it as it was hundreds of thousands of light years ago n not as it would look now just like how they say other planets would be seeing earth back from the days of the dinosaurs if our light were to reach them as they'd see us. N so yea,that's why i think we ain't detectin n seein shlt. Unless Webb is strong enough to actually see far away n be able to perceive it as it would be at this moment.
@@philipsmi-lenguyen8155 Fun fact, according to special relativity, variations in the two way speed of light doesnt break physics (since we have never measured the one way speed of light). This means that if it takes 20 minutes for a light to reach Mars and back... We have no idea if it took 19.9 minutes to get there, and only 0.1 minute to get back..... or if it takes 5 minute to get there, and 15 minutes to travel back... for all we know it could take the entire 20 minutes to get to Mars, and is instaneously relayed back to us. Einstein states that it is just easier for us to comprehend that light travels the same speed in both directions (although physics doesnt break if it doesnt, and we currently have no way of knowing how fast light actually travels in once direction)
This is a great video! (Ok, technically I'm currently only four minutes into it, but so far it's great). But your segue to the sponsor may be the single most hilarious segue I've ever heard and I burst out laughing. That was great!

The mirrors of Webb and Hubble, _normalized for wavelength,_ are much closer in size than the dimensions indicate. Time to invent the _Surfing Helmet._
Good then Ill sell you a 7" pizza at same price of 21" ..ha.. Webb Has 6.25 times more surface area to capture light then the Hubble. Yes Hubble gave us game changing insights to the universe, What will Webb show us. Normalized for wavelength ..yes... gold coating tunes it for the infrared down to 0.6 microns. Hubble 0.8 microns , seems like small difference but its big for the spectrograph we'll get. And yes Hubble telescope structure is comparable in size but mirrors are not ,Webb has 100x the power then Hubble.
True, to some extent, but two things that have to be considered: 1. It is only at the longer wavelengths that it sees that its resolving power is similar to Hubble. At the shorter wavelengths it still has much greater resolving power than Hubble since the shortest wavelength JWST sees is less than double that of hubble. 2. The normalization is only applicable to the resolving power. When it comes to its light gathering capability there is no normalisation to be done.
@@MaximBelooussov you can't, beyond the CMB the universe is too opaque to see, its like trying to look directly into the core of the sun, technically the light can escape the core of the sun, but not before bouncing for a very long time, so any information about the core is too scrambled. the best we can get is polarization, but that is as far as we can go.
Ouch! If you have not already done so, I would see an Opthalmologist, and preferably one with an M.D. certification to make sure the condition of a possible hyphema has been eliminated. A hyphema is a pooling or collection of blood inside the anterior chamber of the eye (the space between the cornea and the iris). I had a similar injury as a teen when the spring on pigeon coupe broke and hit me square in my left eye. I had a half moon shape of blood in my iris and had to lie flat on my back for three days in the hospital for it to properly drain. First time I ever saw my father get pale when I walked into the house with that condition. Take care and thanks for all you hard work!
I got so emotional watching this video! 🥰 I'm so fascinated by all of the possibilities of what we're going to discover! I'm nearing the end of a book titled a short history of nearly everything by Bill Bryson and that book has only made me even more in love with science and physics than I already was, which was a lot. I love this video so much!
I’m a NASA intern this semester and during one of our orientations Gregory Robinson, director of the James Webb telescope program spoke to us! He just said a few words, but that’s been my coolest experience at NASA so far.

Aphysics nerd who also surfs, instant subscribe 🙂 Thanks for this, it really goes a long way to explain why so many are so excited about Webb's success. It makes landing Neil and friends on the moon look like winning a game of Cornhole, and we all know that's the furthest from the truth.
Thanks for this video, I've been waiting for you to address the topic. Thanks also for explaining how you got injured. It's none of my business of course, but I'm relieved that it's a minor injury and you incurred the injury while doing something you love.
Any video that has a thumbnail with a red arrow pointing at something is a must watch for me. No one would just arbitrarily put a red arrow in an image unless there was something really, really important to show.
When they took decades to launch it, they may take years to release data.... جب ایک دھا ئی میں اسے خلا میں چھوڑا، تو معلومات فراہم کرنےمیں کئی سال لگ سکتے ہیں زمانی که چندین دهه طول کشید تا آن را راه اندازی کنند، ممکن است سال ها طول بکشد تا داده ها را منتشر کنند
I can't wait till we get the first break through of life out there, and also the first photo it took its crazy to see how many galaxies are out there, just showing anything is possible for life to be out there.
You wish you had a teacher that took 1/20th of your education time to chat about how you should by this product she is getting paid to tell you to buy? No wonder physics is hard for you to understand.

@Physics Girl I like this video the best of yours (not that I've seen them all) -- the science details, the pleasure of you seeing your editor "get it"... E.g., I appreciate the dominant absorption wavelengths of water/carbon dioxide/methane, and what eras of EM radiation can be seen by HST vs. JWST vs. COBE/WMAP. So nice to have such a video showing two women involved in science posted on the International Day of Women and Girls in Science ! Hoping your head/eye heal completely and soon!
Kapton is seriously awesome.....We use Kapton tape at work and my Engineer asked today how can we isolate the GND vias from a RC filter mod we want to make...I said Kapton. He was worried about the heat from the solder iron, I took a piece of tape stuck it to wood and melted solder on the tape. The wood started burning but the tape was fine....He was so amazed and didn't know Kapton can do this. I then told him about JWST using Kapton as a heat shield. Kapton is awesome
Thank you for making videos.. not only are you super informative, you’re also very accessible, and fun. Your team is always asking cool questions and it really makes for great conversations. Thanks for being the Arcturus in my YT universe of viewing. (Shiny bright star in the void) :)
Amazing how the editing of the video shows the ability to look back in time to see the healing of the surf injury. Sort of what the James Webb telescope is doing.
One thing I heard about the sensitivity of the JWST is this: Imagine looking at a standard kids night light on the moon with one eye but divide that light by 20. Your one eye would see about 1 million photons of light per second from 1/20th of a night light at that range. JWST primary mirror being 6.5 meters (21 feet 4 inches) across will be focused onto and collecting approx. 1 photon per second.
These comparisons are well-intentioned, but mostly completely pointless. Who has any idea what a night light looks like from the moon? Most people don't even have an idea of the distance of the moon.
@@yasminesteinbauer8565 Well a very very small light source that far away giving off a million more photons than JWST will detect is most definitely relatable to me and I suspect many other people that follow science.
@@alex0589 I can imagine all that, but a shark in water is nearly evenly buoyant so not really related to gravity. Spinning on one leg, is more centripetal forces not so much gravitation forces. Do you even English bro?
I know virtually nothing about you but I'm incredibly impressed with all the people that raised you and let you spread your wings. They contributed greatly to our future, as you will also.
when you look very very far into outer space, you are actually looking back millions of years in time. The concepts of space and time are wonderfully and mystically intertwined in nature.
I love JWST, can't wait to see what we can discover with it! I reacted on one thing though, NASA didn't launch it, ESA did... just give credit where credit is due!
@@allualex2606 Well yes, it is. NASA's contribution funded about 85% of the budget. So it must certainly is a "mostly NASA project". ESA funded the launch vehicle & facilities. And ESA & CSA did do some work on some of the instruments. But its absolutely true that NASA funded and did most of it.
lot of respect for this video, in the current day where a lot of people care a lot for camera/video appearence (specially women) - you didnt care or delay posting this video and talking about this even when you are having a bad day shows how much you really like what you are doing, love your content, thanks
I honestly have to say I’ve watched a dozen different videos. By far this has been the most helpful to understanding how the James Webb works.I really enjoyed this video!!! P.S look out for them heaven boards lol
i love Physics Girl, she gets excited about a lot of the same things I enjoy learning about and her passion and enthusiasm for science and understanding is inspirational and keeps me wanting to learn more and more.
I've just started watching your videos and I'm very, very impressed. Your ability to make the incredibly complex at least somewhat understandable is unparalleled. Can you please do a video on dark matter and dark energy? I am very curious as to why our universe continues to expand faster and faster and I think the scientific explanation is related to forces and matter we cannot see or detect. Initially I thought our universe continued to pick up speed because the absence of space and time outside the universe acts sort of like a vacuum to space and time, and the universe is rushing outward to fill the void, not unlike how air rushes to fill a vacuum. Apparently this notion of mine is way off, but no one has been able to explain it in a way that I can grasp. Maybe you will be able to help those of us who struggle to understand this mystery. Thank you!
Nice video! One can see the effort and dedication you've all put into this. And it is well deserved, this telescope is headed to be a real game changer.
I just found this channel today. Five minutes in and I've already smashed the "Subscribe" button. I love Physics Girl's enthusiasm for her subject. I've known for some time that the Andromeda Galaxy is headed for a collision with the Milky Way, but I've never heard the result called "Andromy Way." (Neither has Spell Check, apparently.)
Man, I'm looking forward to the photos the James Webb Space Telescope is going to produce. Apparently its 100 times more powerful than Hubble. So so excited!
No, JWST is not "100 times more powerful than Hubble". Unfortunately that claim has been popularized by some science writers who misunderstood some of the specs (and who should really have known better). JWST and Hubble are very different instruments, and are used for different things. They cannot be easily compared like that. Each one can see things that the other one simply can't (by design). It may be true that the spectrometers on JWST (at some wavelengths) could be 100x more sensitive. But in terms of the optics.... No.
Great video (as usual) Webb is to Hubble like a Bugatti is to my mountain bike I got to say a word in those Native deodorants I am an old school guy (and old, I was on my mom's belly when Armstrong landed in the moon) I wear whatever is on sale but my daughter started having some issues and after some research and trial and error we found out Native, they are very good. Now the whole family uses them
Webb & Hubble are very different instruments. And in fact, Hubble can do/see many things that Webb CAN'T do/see. They complement each other. But one isn't "better" than the other. They each do things better than the other, and they each do things that the other can't do.
I don't know if it is just me but you kind of sound and seem a little different. DId you get check out for a concussion after your accident? Hope all is well.
Dianna: "Do you know anything about it?" Levi: "Not a single thing" Dianna: "Wow, that's so exciting!" I absolutely love your enthusiasm when it comes to teaching physics!
17:06 a girl having knowledge of universe forgets what 'Ag' means. It tells us she was literally going deep in her thoughts about universe stuff and that revolutionary telescope. I can relate that she's too much dedicated. Loved it.
I had my board go through the corner of my mouth. Almost same scenario. When I came up after falling, my leash was stretched and didn't have time to block my board. It was the third or fourth time this happened, but I was able to block the previous ones. Where did you go out, or rather, what beach?
I performed most of the testing on the lightweight carbon fiber materials that were used for the JWT. I'm so grateful for the opportunity to be a part of such a significant piece of equipment that is going to help us to understand so much more of our universe. I can't wait to see what the JWT reveals to us!
@@powerzx that's true. But keep in mind Roman's image resolution is ultimately comparable to Hubble whereas Webb is I believe on equivalent basis 7 times higher. Now Roman has the advantage of much wider field of view which may be it's greatest strength.
A BEARY good look haha 😂 But it’s incredible what everyone can put together: enormous machines with very, very, VERY precise instruments and it all has to weigh as little as possible! And then to think of all the research that can be done with it in the decades to come. I wish haha 😅 But what I’m left wondering is how they’re communicating with the telescope and how it feels compared to other satellites and rovers. Could that maybe be a future video (if this ever gets seen)?
I think communication will be the same as it is with other satellites, orbiters and rovers, by radio waves, so communicating with the JWST. will need patience because of the wait times due to the distance.
I know I'm picky but... It's the Esa who launched the telescope. Yes Nasa provided the most funds, the most scientist and all but it's thanks to the Esa and Ariane launcher that the James webb telescope gained 10 years of work life. Esa didn't do most of the work but it probably did the most critical one. So some credits would be appreciated.
I read about the engineers at ESA who went above and beyond to purposefully pick all the best matched components (stages, engines, etc) to build the ideal Ariane rocket so it would have the best chance of delivering the Webb to its ideal point to begin its mission to L2. Apparently they did such a good job that Webb has enough fuel to stay on station for 20 years. This doubled the time everyone expected it would have in service, the folks at the ESA deserve high praise indeed.
yeah, I'm pretty disappointed as well that she didn't mention the international effort, but I assume that the info got lost in script revisions or because this video had to be produced quickly, since it's referencing a current event.
Have we tried to look even lower than infrared from outer space location? Can we look into the radio wave spectrum or even longer wavelength? How long can we go until it is theoretically almost a particle without a wave?
Radio telescopes. Tons of them everywhere, they can do that right on Earth. That's not as interesting (well to some), the infrared has a special place in astronomy and physics in general because when you select the right target to look at it can be used to do molecular analyses of things, so we can learn more about what is giving off the light not just that there is light coming from it. It's limited it can't detect everything but it's probably one of the most scientifically interesting instruments on JWST. There are other reason the infrared is useful because all the light coming from stars close to the big bang are so red shifted their optical light has been stretched out to the lower frequency so it exists in infrared now. Space is literally stretching the color of the light. I'm not 100% sure of this but I think they may be able to give us visible light optical images if we look far enough away, they'll just take the infrared light they receive and shift all the frequencies over so that we get the optical equivilent. But at that distance I'm not sure what the resolving power would be so I don't know how interesting those images would be. I have my hopes though :)
Great video, wish you a speedy recovery. One question, in the beginning of the video you said NASA launched the telescope. Is it only the NASA or NASA and ESA together?
I try to spread Science by comment all over the comment-section: Check out more and more Sci-TH-camr! Like Sci Show! Sci Man Dan and Professor Dave! Be Smart!
I love your energetic enthusiasm and perspective on the current physics. It rubs off on. I can't help but feel excited about new research and discoveries. Thank you, Diana.
@Physics Girl have you looked into the crazy cooling for the JWST? 36 Kelvin is still too hot for its computer! The cooling pump is amazing and uses liquid helium.
Once you start saving and investing to your utmost ability, buying into your portfolio and seeing it grow is far more gratifying than piling up more stuff you don't need in your house, trust me.
My hypothesis is that the universe is a 0-dimensional point. That this can spin around its self, and the initial frequency is infinity. The second frequency is f = c/d. (The second "frequency" emerged from periodic functions that happened to create the shape of a proton in 11 dimension.) The proton also has a fundamental harmonic inside its self that is the positron. The electron was able to really quickly split and recombine through higher dimensions in such a way as the electron acted like it went back in time to "recruit" its self as another electron to balance out the next proton collapse (associated with its correlated positron). This all happened really quickly during the "big bang". There are ways we can look for it. Look back in time at the "big bang". Recreate the events by creating conditions with energy levels closer to that of the "big bang". By doing that, I think, we're sort of making a lens that is focusing the 11 dimension back into the point and if the energy is high enough, we could briefly sort of make out how a point moving at "infinite speed" would look for the time that it was some kind of mass.
The way Diana's face lights up every single time she explains something to her editor is so nice to see.
i see you here solely for the physics then.
i wonder if this channel would be nearly as popular if she was a munt.
I think that's a bruise :-D
I wish we could see the editor to see his reaction too.
I love the way she gleefully describes the epic brutality of a trebuchet death.
Yeah, I think it´s brilliant, that back-and forth with the editor makes some of the more complex explanations so much more relatable and easier to follow.
two amazing things that no one mentions: the flap on the back of the telescope is a small solar sail, its going to be used to help rotate the telescope to reduce the saturation of the gyros. another thing is that its so freaking cold on the shade side of the telescope, that you actually can use superconductors, and that is exactly what they did, some components are made of superconductors to reduce weight.
Wow that's awesome. Thanks for the information. It's really interesting and exciting the more I find about this telesc
You know… I didn’t even think about the possibility before of super-cold superconductors being practical in space, but here we are! That’s awesome
Yeah, it's not much but ANY form of thrust they can get saves fuel. The recent loss of the 40 Starlink satellites might be of interest to you, they use wires of some kind they deploy that interacts with the magnetic field along with thrusters to move the ship, leveraging the earths own magnetic field for orientation changes, it's damn near magical. They lost the satellites because the atmosphere swells when it's hit by a solar ejection/wind and their system would no longer work because of too much drag.
The thrust they get out is pitiful, but it's 'free''
@@millicentduke6652 generally superconductors aren't practical "close" to the sun (massive quotations around close). Howeger when the ship needs to be incredibly cold anyways it's the natural fit. Since superconductors produce less heat then normal wires actually.

My 5 year old daughter, and I, love watching your videos! She says she wants to be a scientist when she grows up - so thank you for being an inspiration to her! Hope your eye feels better soon. :)
Shut up
@@Zarro0o0o You shut up.
My uncle got me into science when I was a teenager. He was very excited about this project for over a decade. He said "seeing what happens" in space science was one of his reasons for living. Unfortunately, he passed away last summer and I was often reminded of how much he would have loved to see the images that will be coming out later this year.
Very sorry to hear about your uncle. We will all appreciate the images that the JWST captures in his stead.
I relate so hard, after this telescope, there are plans to launch LUVIOR telescope, which can see in ultraviolet as well. This planned telescope have much much larger mirrors and can see more far and in much more detail. But, by the time that will be launched I will become old. Knowing this fact hurts.
Sorry for your loss.
Rejoice in knowing he's seeing what happens.
What do you know about the Earths failing electro magnetic field? I hope you know a lot about that.
Condolences. Know that your uncle loved every second of getting you excited about science. One of the joys in my life is passing along to my niece what little scientific knowledge I have, and experiencing and learning with her. I hope her memories with me will be as fond as yours with your uncle.
Been loving this format where you're chatting with your editor! Great video as always, keep at it and have a quick recovery on that eye!
tube! Absolutely agree! It is always great to hear 2 people interacting over anything exciting
It's like sitting in on a conversation with a professor and student. Very cool format to learn and I like the parts where the camera is angled so it's like you are sitting at the table with them.
Really? I've never been able to get through one. He never seems to know anything.
Gives me hope. As in, those boring conversations where I go on and on and I see the life slowly drain from the eyes of my conversant over the course of an hour can be redeemed with good editing!
@@tbird-z1r Honestly, Her editor is hitting on her. Not that there's anything wrong. Pretending to be interested in physics stuff, asking random questions just to get her excited and spend time with her and talking to her for hours. Kind of obvious to be honest. Anyone that is interested in this kind of stuff is at least good with the basics or curious enough to google it themselves.
There's an old XKCD comic that explains how impossible it is to know EVERYTHING so if someone says they don't know something, you shouldn't criticize them but rather get excited that you have the opportunity to introduce them to something new and cool. The best part of this channel is that Dianna takes this to heart, and it is wonderful.

Great amount info w/just as much personality. I feel bad about that surfboard incident. A slight imperfection; when regarding deodorant/best not to invoke the"southern hemisphere"(Australia). It was good 4 a laff i guess.
Disagree.
I don't like the format. Having a fake guided QnA with a guy who doesn't even know the right questions to ask ends up explaining/communicating meaningless little factoids (I couldn't care less how far the JWST is scaled down to a random coin), while the remainder of the video doesn't go beyond repeating what dozens of other science communicators already explained ad nauseam.
Tell me something of relevance I haven't heard yet and you've earned yourself a subscription. Otherwise there's no point because you're just regurgitating the same thing people already talked about weeks before you.
@@dominic.h.3363 These things happen, but it was new 2 Me. Consider Yourself lucky w/info.
Except right from the beginning: "NASA launched the most powerful telescope ever made" is, of course, incorrect. JWST is nowhere near the most powerful telescope ever made.

I just discovered your channel and love it! I postdocked at MIT almost 50 years ago. I loved the environment. Everyone there was interested in what I was doing making it the most fertile environment for learning that I have enjoyed. Your enthusiasm, brilliant mind, and quick wit make me feel like I am back at MIT. I have already come to understand things I have puzzled about for years from watching just a few of your videos. I look forward to learning a lot more.
Seeing somebody let their passion and excitement shine so brightly while teaching - especially in the sciences - is so wonderful. Fantastic video, Dianna (and team)!

Wow! Dianna is an amazing science educator!!sad that she had a sports accident but luckily not too bad… Exciting episode indeed!! I also watched an episode specifically about the orbit of JWST however defined around the Lagrange point I suppose on Launch Pad Astronomy - I hope you find it interesting to watch if you do in addition to everything Dianna stars in etc - I must say for everyone including us adults however defined I feel things like Dianna’s NASA episodes are amazing to take our minds away from other mundane and also difficult daily things like Covid precautions etc - Thanks again Dianna & all!🔭🔭🔭🔭🔭🎬♾☮️💟🌈😻🥰😘🤯🗽
PG: I absolutely LOVE watching your videos. Had you been my science teacher I may have moved in a different direction. You make topics interesting and relatable. Love your enthusiasm and intellect!
I love how simply you describe very complex things. While I've read and watched a lot about JWST, the Fanta explanation for finding life made more sense than anything I've seen so far.
Really looking forward to seeing images from JWST. Hope it finds stuff that nobody is even expecting, and it takes us further into a whole new era of interstellar, intergalactic awareness.
They only limitation with be the imagination
That's probably the most exciting thing about JWST for me, it's not the things that we're expecting that will be interesting, it's all the new things we'll see that we weren't expecting that will be the most interesting. This is how science progresses. Not with a Eureka!"" moment but with "That's odd"
It will find fully formed solar systems, planets, stars, and galaxies. No one is expecting that except the young earth creation model.
How have I gone this long in my life without you? Great content!! I will be a regular viewer as long as you keep being excited about science!
Woke up, went surfing. That sounds like paradise! And now to the substance: You made me understand the progress of the James-Webb-Telescope. Thank you so much! That literally will be the first thing I will explain to my 6th and 8th graders in school next week.
First time watcher-now subscriber. This was one of the best videos I’ve seen on JWST and just science in general. I love your intelligence and easy going nature in explaining things you’re passionate about.
Stay blessed and please watch out for the flying surf boards. You were very fortunate.

6:20 OF COURSE Dianna has a cosmic microwave background plushie 😄
This is so cool, one of my best friends worked on this telescope. Awesome to see some of the tech he developed in use!
I can remember being in awe after seeing some of the earliest images, of gorgeous stellar nurseries, produced by the *Hubble Telescope* (after the mirror was fixed & colour-corrected).
Several years further on, *The Hubble Deep Field Image* was developed (from a composite of 342 images) & I was utterly blown away with the huge number of entire *Galaxies* seen in such an infinitesimally small section of the sky _(2.4 arcminutes a side / 24-millionth of the whole sky / or the area of a freakin' tennis ball @ 100 meters away!)_ - implying a truly staggering quantity of *Galaxies* in *The Known Universe.*
Now, decades later, I get to see the amazing things that the *James Webb Infrared Telescope* will show of the early days of *Stellarsynthesis,* potentially habitable worlds & even *Infrared* views of the center of *The Milky Way,* without the obscuring dust blocking it - perhaps even high-resolution images of *Sagitarius A**
Did you know that with a small 80mm to 102mm (3 to 4 inch) telescope by stacking pictures you can get awesome big telescope like pictures? There are apps for stacking too. I use a 150mm (6 inch) to star gaze, but use a 102mm set up for astrophotography.
implying a truly staggering quantity of
Read more?
What does that mean?
What a fantastic video - super classy! Love the enthusiasm sorely missing today. Please keep us informed on developments.
Was a Reliability Engineer on HST development for several years including initial deployment and also repair/maintenance missions, such a success story over our failure modeling, predictions, mission life, etc., super cool to have worked on the HST mission - With respect to JWST, mega exciting but wow $10 Billion is quite the expenditure based on original estimates, schedule, etc. - Anyway, the science implications and potential discoveries I assume are going to be quite enlightening - Mission success so far with launch, deployment, and calibration are truly incredible based on spacecraft complexity and everything functioning so far as designed - It's going to get interesting for sure... \m/
So many amazing and straightforward answers to questions about how humanity's newest eye is going to look at the universe. L4/L5 is stable so there is random space junk there, so we sent our telescope to L2. Such a great explanation, Dianna!
L2 is also much closer than L4/L5 (1m miles instead of 90m), so data transfer is easier
best I can tell it's a spasm between L4 and L5
Main reason for L2 is shade from earth
One thing I learned about that I thought was super cool was that we could also look for technosignatures. On top of the elements of biological processes, if there were a civilization on a distant planet, we could also potentially see silicon signatures like we do here on Earth which would be a much more definitive sign of advanced life or civilization on a planet, in concert with the appropriate biosignatures of course.
Interesting thought. Imagine life in the universe developed everywhere in about the same time. Right now there would be millions of civs that are only a few thousand years more or less far developed as we are. What would be the time that the techno signatures needed to travel between two civs so that one 'sees' the other? If all civs survive, will there be an era of techno signature flooding in the far future?
Until we can somehow bridge a gap of millenia, I'm not overhype for finding intelligent life on a planet in a star system shining over 2k LY distant. Like, so what? What are we gonna do? The odds of a civilisation lasting and still remaining intact by the Time it took to reach it, I reckon, are slim. Then figure in the time it takes their EM telltale to reach our solar system, at Light speed its 2k years, so at minimum a span of 4k years from discovery to first contact give or take turnaround time (getting the journey craft put together etc). Plenty of time for Earth to forget, or its own civilisation to suffer a system collapse, or destroy itself, and all that negative stuff... We're talking a seriously longgg lead time here.
@@santyclause8034 cant tell if you enjoy being pessimistic, but the entire thought of there being other life out there than just us is amazing in itself.....It's well known that special relativity and the standard model are both wrong (or at least incomplete), and the majority of us already understand that there is an unfathomable amount of space between us and other celestial objects.... It literally doesnt change anything, and wont stop us from trying anyways. You have no way of knowing that in future we wont solve this issue. Humans have been able to accomplish anything we've set our mind to so far. We live on the edge of AI - Human symbiosis, there's no telling what we will do.
But we still wouldn't be able to detect it anyways. Cause light reaches us faster than any other signals we can read like the technosignatures or radio waves n such. N so if by the time we see the light from where whichever planet we are aimed n looking at,we'd be seeing it as it was hundreds of thousands of light years ago n not as it would look now just like how they say other planets would be seeing earth back from the days of the dinosaurs if our light were to reach them as they'd see us. N so yea,that's why i think we ain't detectin n seein shlt. Unless Webb is strong enough to actually see far away n be able to perceive it as it would be at this moment.
@@philipsmi-lenguyen8155 Fun fact, according to special relativity, variations in the two way speed of light doesnt break physics (since we have never measured the one way speed of light). This means that if it takes 20 minutes for a light to reach Mars and back...
We have no idea if it took 19.9 minutes to get there, and only 0.1 minute to get back.....
or if it takes 5 minute to get there, and 15 minutes to travel back...
for all we know it could take the entire 20 minutes to get to Mars, and is instaneously relayed back to us. Einstein states that it is just easier for us to comprehend that light travels the same speed in both directions (although physics doesnt break if it doesnt, and we currently have no way of knowing how fast light actually travels in once direction)
Your analogies make me chuckle in a good way 15:46 Severed heads, and 16:20 trebuchet splatter.
This is a great video! (Ok, technically I'm currently only four minutes into it, but so far it's great).
But your segue to the sponsor may be the single most hilarious segue I've ever heard and I burst out laughing. That was great!

The mirrors of Webb and Hubble, _normalized for wavelength,_ are much closer in size than the dimensions indicate.
Time to invent the _Surfing Helmet._
so the main question would be - what wavelength/mirror size should next telescope use to see the big bang?
Good then Ill sell you a 7" pizza at same price of 21" ..ha.. Webb Has 6.25 times more surface area to capture light then the Hubble. Yes Hubble gave us game changing insights to the universe, What will Webb show us. Normalized for wavelength ..yes... gold coating tunes it for the infrared down to 0.6 microns. Hubble 0.8 microns , seems like small difference but its big for the spectrograph we'll get. And yes Hubble telescope structure is comparable in size but mirrors are not ,Webb has 100x the power then Hubble.
True, to some extent, but two things that have to be considered:
1. It is only at the longer wavelengths that it sees that its resolving power is similar to Hubble. At the shorter wavelengths it still has much greater resolving power than Hubble since the shortest wavelength JWST sees is less than double that of hubble.
2. The normalization is only applicable to the resolving power. When it comes to its light gathering capability there is no normalisation to be done.
@@MaximBelooussov you can't, beyond the CMB the universe is too opaque to see, its like trying to look directly into the core of the sun, technically the light can escape the core of the sun, but not before bouncing for a very long time, so any information about the core is too scrambled. the best we can get is polarization, but that is as far as we can go.
Ouch! If you have not already done so, I would see an Opthalmologist, and preferably one with an M.D. certification to make sure the condition of a possible hyphema has been eliminated. A hyphema is a pooling or collection of blood inside the anterior chamber of the eye (the space between the cornea and the iris). I had a similar injury as a teen when the spring on pigeon coupe broke and hit me square in my left eye. I had a half moon shape of blood in my iris and had to lie flat on my back for three days in the hospital for it to properly drain. First time I ever saw my father get pale when I walked into the house with that condition. Take care and thanks for all you hard work!
I got so emotional watching this video! 🥰 I'm so fascinated by all of the possibilities of what we're going to discover!

Thanks for this, it really goes a long way to explain why so many are so excited about Webb's success. It makes landing Neil and friends on the moon look like winning a game of Cornhole, and we all know that's the furthest from the truth.
The JWST was launched by Arianespace / ESA. The payload was a NASA/ESA/CSA collaboration .
Thanks for this video, I've been waiting for you to address the topic. Thanks also for explaining how you got injured. It's none of my business of course, but I'm relieved that it's a minor injury and you incurred the injury while doing something you love.
Any video that has a thumbnail with a red arrow pointing at something is a must watch for me. No one would just arbitrarily put a red arrow in an image unless there was something really, really important to show.
Hope to see Webb's Ultra Deep Field this summer.

E.g., I appreciate the dominant absorption wavelengths of water/carbon dioxide/methane, and what eras of EM radiation can be seen by HST vs. JWST vs. COBE/WMAP.
So nice to have such a video showing two women involved in science posted on the International Day of Women and Girls in Science !
Hoping your head/eye heal completely and soon!
Kapton is seriously awesome.....We use Kapton tape at work and my Engineer asked today how can we isolate the GND vias from a RC filter mod we want to make...I said Kapton. He was worried about the heat from the solder iron, I took a piece of tape stuck it to wood and melted solder on the tape. The wood started burning but the tape was fine....He was so amazed and didn't know Kapton can do this. I then told him about JWST using Kapton as a heat shield.
Kapton is awesome
15:48 - 16:03 might be the greatest scientific breakdown of the mirrors weight
Thank you for making videos.. not only are you super informative, you’re also very accessible, and fun. Your team is always asking cool questions and it really makes for great conversations.
Thanks for being the Arcturus in my YT universe of viewing. (Shiny bright star in the void) :)
The way you explain it, talk about and make it reliable as someone with adhd my brain was about to keep up, thank you
Thinking about cosmology is one of the things that helps me keep going in these "interesting times".
SO wished I had a teacher like you at high school, mine were all boring AF and didn't inspire me to take up science at all!
Amazing how the editing of the video shows the ability to look back in time to see the healing of the surf injury. Sort of what the James Webb telescope is doing.
I love these explanation videos so much!
This made me emotional. This and Dr. Becky channel are my fav scientific ones on YT
One thing I heard about the sensitivity of the JWST is this: Imagine looking at a standard kids night light on the moon with one eye but divide that light by 20. Your one eye would see about 1 million photons of light per second from 1/20th of a night light at that range. JWST primary mirror being 6.5 meters (21 feet 4 inches) across will be focused onto and collecting approx. 1 photon per second.
These comparisons are well-intentioned, but mostly completely pointless. Who has any idea what a night light looks like from the moon? Most people don't even have an idea of the distance of the moon.
@@yasminesteinbauer8565 Well a very very small light source that far away giving off a million more photons than JWST will detect is most definitely relatable to me and I suspect many other people that follow science.
"imagine a hammerhead shark but on neptune, then lift one leg and spin around, THAT'S how much gravity is on Phobos"
- you, probably
@@alex0589 I can imagine all that, but a shark in water is nearly evenly buoyant so not really related to gravity. Spinning on one leg, is more centripetal forces not so much gravitation forces.
Do you even English bro?
All the people who worked on this telescope are just amazing.
Im so curious about what it will discover.
I know virtually nothing about you but I'm incredibly impressed with all the people that raised you and let you spread your wings. They contributed greatly to our future, as you will also.
Went back here just to see if someone has commented about the pictures JW just released!
She says it's a surfing injury but secretly she's been fighting the ninja minions of a super villain.
Hmm we already know Rohin is Ronin.. I wonder how many other TH-camrs are secretly superheroes/villains.
This channel is very well edited. Having the visual aids alongside the explanations, really really helps. Thank you.
when you look very very far into outer space, you are actually looking back millions of years in time.
The concepts of space and time are wonderfully and mystically intertwined in nature.
I love JWST, can't wait to see what we can discover with it! I reacted on one thing though, NASA didn't launch it, ESA did... just give credit where credit is due!
It's a NASA project... mostly
@@rickkwitkoski1976 Its not.
@@allualex2606 Well yes, it is. NASA's contribution funded about 85% of the budget. So it must certainly is a "mostly NASA project".
ESA funded the launch vehicle & facilities. And ESA & CSA did do some work on some of the instruments.
But its absolutely true that NASA funded and did most of it.
lot of respect for this video, in the current day where a lot of people care a lot for camera/video appearence (specially women) - you didnt care or delay posting this video and talking about this even when you are having a bad day shows how much you really like what you are doing, love your content, thanks
I honestly have to say I’ve watched a dozen different videos. By far this has been the most helpful to understanding how the James Webb works.I really enjoyed this video!!! P.S look out for them heaven boards lol
I love your explanations of the JWST functions, and always your enthusiasm. Watch out for the Surf Board Monster!
i love Physics Girl, she gets excited about a lot of the same things I enjoy learning about and her passion and enthusiasm for science and understanding is inspirational and keeps me wanting to learn more and more.
I've just started watching your videos and I'm very, very impressed. Your ability to make the incredibly complex at least somewhat understandable is unparalleled. Can you please do a video on dark matter and dark energy? I am very curious as to why our universe continues to expand faster and faster and I think the scientific explanation is related to forces and matter we cannot see or detect. Initially I thought our universe continued to pick up speed because the absence of space and time outside the universe acts sort of like a vacuum to space and time, and the universe is rushing outward to fill the void, not unlike how air rushes to fill a vacuum. Apparently this notion of mine is way off, but no one has been able to explain it in a way that I can grasp. Maybe you will be able to help those of us who struggle to understand this mystery. Thank you!
Thanks physics girl for sharing all your knowledge , well I though the first findings have come from James web already 😀 so curious
@tradde11 thanks for the update .well I hope James Webb gives you a better clarity and deeper insights , god speed
Yeah, the first image has been taken.
Nice video! One can see the effort and dedication you've all put into this. And it is well deserved, this telescope is headed to be a real game changer.
Yep!
I just found this channel today. Five minutes in and I've already smashed the "Subscribe" button. I love Physics Girl's enthusiasm for her subject. I've known for some time that the Andromeda Galaxy is headed for a collision with the Milky Way, but I've never heard the result called "Andromy Way." (Neither has Spell Check, apparently.)
Shut up
So far, the best explanation for the JWST. Thank you Dianna for a simple "earthly" translation! I hope you are feeling better than the surf board 😊
Man, I'm looking forward to the photos the James Webb Space Telescope is going to produce. Apparently its 100 times more powerful than Hubble. So so excited!
No, JWST is not "100 times more powerful than Hubble". Unfortunately that claim has been popularized by some science writers who misunderstood some of the specs (and who should really have known better).
JWST and Hubble are very different instruments, and are used for different things. They cannot be easily compared like that. Each one can see things that the other one simply can't (by design).
It may be true that the spectrometers on JWST (at some wavelengths) could be 100x more sensitive. But in terms of the optics.... No.
Great video (as usual) Webb is to Hubble like a Bugatti is to my mountain bike
I got to say a word in those Native deodorants I am an old school guy (and old, I was on my mom's belly when Armstrong landed in the moon) I wear whatever is on sale but my daughter started having some issues and after some research and trial and error we found out Native, they are very good. Now the whole family uses them
Webb & Hubble are very different instruments. And in fact, Hubble can do/see many things that Webb CAN'T do/see.
They complement each other. But one isn't "better" than the other. They each do things better than the other, and they each do things that the other can't do.
🎉🎉🎉
Thanks!
I don't know if it is just me but you kind of sound and seem a little different. DId you get check out for a concussion after your accident? Hope all is well.
Dianna: "Do you know anything about it?"
Levi: "Not a single thing"
Dianna: "Wow, that's so exciting!"
I absolutely love your enthusiasm when it comes to teaching physics!
I don't believe him. I suspect he's exaggerating his lack of knowledge a little, for the sake of the video format.
Spectroscopy so well explained!
Well, to be more precise: "The universe, life and everything" better explained, you are such an excellent explainer!
17:06 a girl having knowledge of universe forgets what 'Ag' means. It tells us she was literally going deep in her thoughts about universe stuff and that revolutionary telescope. I can relate that she's too much dedicated. Loved it.
I am wounded. I get it, I get it, but still, ouch. She forgot about me!
Agriculture or silver?
@@silveralmerlov9609
Is “Silver” your real, given name? Or just a chosen interwebz name?
I had my board go through the corner of my mouth. Almost same scenario. When I came up after falling, my leash was stretched and didn't have time to block my board.
It was the third or fourth time this happened, but I was able to block the previous ones.
Where did you go out, or rather, what beach?
I performed most of the testing on the lightweight carbon fiber materials that were used for the JWT. I'm so grateful for the opportunity to be a part of such a significant piece of equipment that is going to help us to understand so much more of our universe. I can't wait to see what the JWT reveals to us!
You are amazing love from India want to meet you as your obedient student
?
Quick question: if the JWT was the dream telescope when Hubble launched, what is the dream telescope now?
LUVOIR and Habex... Look them up. They were selected from the decadal study. Source: myself @NASA ;)
Nancy Grace Roman telescope.
@@powerzx WFIRST? oh no no that's not the dream telescope at all... That's on the class of a much smaller less powerful telescope.
@@nyer070 LUVOIR will be made later, I said which will be next. For some it may be "a dream telescope" for some not.
@@powerzx that's true. But keep in mind Roman's image resolution is ultimately comparable to Hubble whereas Webb is I believe on equivalent basis 7 times higher. Now Roman has the advantage of much wider field of view which may be it's greatest strength.
Cool video with lots of details and valuable info. thanks for sharing. Surfs up ! Did your eye heal well ?
A BEARY good look haha 😂
But it’s incredible what everyone can put together: enormous machines with very, very, VERY precise instruments and it all has to weigh as little as possible! And then to think of all the research that can be done with it in the decades to come. I wish haha 😅
But what I’m left wondering is how they’re communicating with the telescope and how it feels compared to other satellites and rovers. Could that maybe be a future video (if this ever gets seen)?
Your comment is seen, seen by bots 😂😂
@@OxygenOS So report no?
I think communication will be the same as it is with other satellites, orbiters and rovers, by radio waves, so communicating with the JWST. will need patience because of the wait times due to the distance.
@@johnzuijdveld9585 Yup! Already reported.
😊
I know I'm picky but... It's the Esa who launched the telescope. Yes Nasa provided the most funds, the most scientist and all but it's thanks to the Esa and Ariane launcher that the James webb telescope gained 10 years of work life.
Esa didn't do most of the work but it probably did the most critical one. So some credits would be appreciated.
I read about the engineers at ESA who went above and beyond to purposefully pick all the best matched components (stages, engines, etc) to build the ideal Ariane rocket so it would have the best chance of delivering the Webb to its ideal point to begin its mission to L2. Apparently they did such a good job that Webb has enough fuel to stay on station for 20 years. This doubled the time everyone expected it would have in service, the folks at the ESA deserve high praise indeed.
yeah, I'm pretty disappointed as well that she didn't mention the international effort, but I assume that the info got lost in script revisions or because this video had to be produced quickly, since it's referencing a current event.
Your enthusiasm is so contagious! Feel better, Diana.
Have we tried to look even lower than infrared from outer space location? Can we look into the radio wave spectrum or even longer wavelength? How long can we go until it is theoretically almost a particle without a wave?
Radio telescopes. Tons of them everywhere, they can do that right on Earth. That's not as interesting (well to some), the infrared has a special place in astronomy and physics in general because when you select the right target to look at it can be used to do molecular analyses of things, so we can learn more about what is giving off the light not just that there is light coming from it. It's limited it can't detect everything but it's probably one of the most scientifically interesting instruments on JWST. There are other reason the infrared is useful because all the light coming from stars close to the big bang are so red shifted their optical light has been stretched out to the lower frequency so it exists in infrared now. Space is literally stretching the color of the light.
I'm not 100% sure of this but I think they may be able to give us visible light optical images if we look far enough away, they'll just take the infrared light they receive and shift all the frequencies over so that we get the optical equivilent.
But at that distance I'm not sure what the resolving power would be so I don't know how interesting those images would be. I have my hopes though :)
Great video, wish you a speedy recovery. One question, in the beginning of the video you said NASA launched the telescope. Is it only the NASA or NASA and ESA together?
I try
to spread Science by comment all over the comment-section:
Check out more and more Sci-TH-camr!
Like Sci Show! Sci Man Dan and Professor Dave! Be Smart!
I love your energetic enthusiasm and perspective on the current physics. It rubs off on. I can't help but feel excited about new research and discoveries. Thank you, Diana.
@Physics Girl have you looked into the crazy cooling for the JWST? 36 Kelvin is still too hot for its computer! The cooling pump is amazing and uses liquid helium.
Physics girl: "It would be 9 feet away"
Me: Tries to imagine 9 actual feet from a coin because me have no intuitions in imperial units
Thanks for making this easy to understand. Fantastic work, Physics Girl. Keep this creative, educational content coming.
Once you start saving and investing to your utmost ability, buying into your portfolio and seeing it grow is far more gratifying than piling up more stuff you don't need in your house, trust me.
Amazing, it's fascinating to see that someone here enjoys Mrs Bernice trading strategy
I got her recommendations on CNBC news last month
And I've made a profit of 32000usd
I'm not surprised because I've made over 180k, following her advice and guidance
I've seen a lot of recommendation about
Mrs.Bernice, how do I follow her?
What a warrior. Working through a bad injury and still doing a great job.
This girl is just precious. Intelligence and beauty together is a rare find.
My hypothesis is that the universe is a 0-dimensional point. That this can spin around its self, and the initial frequency is infinity. The second frequency is f = c/d. (The second "frequency" emerged from periodic functions that happened to create the shape of a proton in 11 dimension.) The proton also has a fundamental harmonic inside its self that is the positron. The electron was able to really quickly split and recombine through higher dimensions in such a way as the electron acted like it went back in time to "recruit" its self as another electron to balance out the next proton collapse (associated with its correlated positron). This all happened really quickly during the "big bang". There are ways we can look for it. Look back in time at the "big bang". Recreate the events by creating conditions with energy levels closer to that of the "big bang". By doing that, I think, we're sort of making a lens that is focusing the 11 dimension back into the point and if the energy is high enough, we could briefly sort of make out how a point moving at "infinite speed" would look for the time that it was some kind of mass.
I'm so glad for Levi asking questions that going through my head
Destin introduced us me to your channel. You both have that enthusiasm to communicate and teach. Thank you.
