- My take on the images released by the JWST earlier this week, a whole new level of detail is now possible with this new instrument. Moreover, I wanted to answer some questions about what we're seeing in the images, and, why the stars have 8 points while Hubble images only show 4.

I'm 86 and I'm glad I lived long enough to see these images. When I was a kid the universe was already unimaginably big. The thought that even the smallest of these dots of light might be another Milky Way and that the whole image is just a tiny rectangle on the celestial sphere absolutely defines the word "mind-blowing". Thanks Scott for the tour!
Live long and prosper!
I'm only 70 years old but I share your sentiments.
Big respect to you for having an open mind to space and technology, not many older people do. Live long and prosper.
The great deception is the Un-inverse from the Catholic Jesuit priestclass, there are no gas balls burning forever in a space vacuum and these images are a lie!
Sorry you lived long enough to see these disgusting furries
Don't know about anyone else, but that's the best breakdown of the most recent images of JWST I've seen! Thanks Scott!
Yes... but Anton Petrov did a fantastic job too ! Scott and Anton are my two go to astronomy popular educators. Scott and Tim Dodd are my two for rocketry.
@LSA & @Paul Walsh I certainly agree. Both first early presentations were outstanding. But there is so much to be seen (like a whole universe), so much detail to comprehend. The future looks bright for astronomy - and for our own "lay" enjoyment!! And there will be many other future, more powerful and innovative ways to see and sense that universe - e.g., maybe gravitational wave telescopes (like LISA Pathfinder, etc.)
Isn’t he lovely isn’t he fine , can describe in a way that we understand so thanks Scott for all your wonderful lines , and now I will shut up and listen as I’m just an ignorant kiwi fan
Yes! I was thinking the exact same thing. This is the exact sort of thing I was expecting to see when I tuned into the big reveal.
I concur :-)
I’ve seen all space UA-camrs go nuts with these images posting vids but Scott just does it differently. Speaks to us like we arnt just the general public who have zero understanding of this stuff but speaks to us more rather like the space nerds we are. I appreciate that.
“You're a smart bunch, I don't have to explain what infrared is to you as if you're stupid. Now this picture…” ― Scott Manley, probably
Anton Petrov and Fraser Caine are two others.
@@zefallafez mmm I’d argue that those two also dumb things down a bit. Great commentators though don’t get me wrong
@@steviesteveo1 Problem is unlike sports, the target audience you mention is small. Good, bad, or indifferent, news is there to capture an audience.
What's perhaps most interesting to me is that the "false color" scheme used for JWST is different than that used for Hubble. Hubble played a huge role in determining how several generations of people think about what space "looks like." The new color scheme means that coming generations will have different ideas about what space looks like! So interesting to think about how these images can change the way entire generations think about space
Unlike Hubble these images are captured via infrared sensor so all colours are "fake".
its just CGI.... artist impression rubbish
@@esecallum no it isn't lol. You think someone went through star by star and colored in every Hubble pic? The false color depends on the wavelength of light that's detected. It's just not visible light so they have to assign the wavelengths we can't see to portions of the spectrum that we can see
@@esecallum tell us you do not understand infrared images are not visible in our visual spectrum without telling us you know nothing about infrared images.
@@esecallum Oh look, a triggered space denier getting his world view crushed.
When Scott explains, things are more interesting and fun.
Yes, indeed. Oh, and don't forget "Dr. Becky". She was super excited and also gave some very interesting insights.
Next I want him to explain why she left me
@@askhowiknow5527 “Hello it’s Scott Manley here. This guy’s got a small pp and that’s just fascinating.”
Far Far Better then the politicians can do.
I like that Scott doesn't dumb down his explanations to the level of condescension. The layperson can get the gist of what he's saying, but he sprinkles enough technical terminology throughout his videos that those looking to gain a fuller understanding of what he's saying will be rewarded for doing additional research.
Got the same chills I did as a kid looking at Hubble images. It's going to be fun seeing what JWST produces for us over its lifetime.
I wouldn't be surprised if they can squeeze even more life out of the telescope. One thing is for sure, I have a lot more respect for ESA. They really went above and beyond with the launch of JWST.
I think they built in some buffer for things going wrong, then put enourmous effort into minimizing the chance of something going wrong, and everything worked perfectly. For example, the calculated extra fuel to spin it, in case one of the 100 something pins got stuck. Then they fiddled with the pins till they only got stuck one in 10's of thousands of times. Now they can use that fuel for staying in L2 longer.
ESA is not a launch provider. 😏
@@nabormendonca5742 ESA does provide the Ariane 5. I read somewhere that the JWST didn't have to burn as much fuel as was planned in order to position itself because the ESA was so spot on with the launch.
@@julians7268 Technically Arianespace is the provider, but with the way ESA is setup, I would pretty much lump them in there.
@@fiveoneecho Everywhere I'd seen it spoken of they refer to it as though ESA is the provider. I appreciate the clarification.
This is such relief to see JWST up and running and producing data. This was such a nerve wracking trip and the payoff will be enormous. Fingers crossed the whole mission will work out fine and we’ll get hundreds of these incredible images and observations.. thank you Scott for that deep dive into these deep images ;)
فَلَا أُقْسِمُ بِمَوَاقِعِ النُّجُومِ، وَإِنَّهُ لَقَسَمٌ لَوْ تَعْلَمُونَ عَظِيمٌ، إِنَّهُ لَقُرْآَنٌ كَرِيمٌ، فِي كِتَابٍ مَكْنُونٍ
@Karl with a K it has taken damage by several micro impacters. i read at least one impacts is not fixable by recalibration of the mirrors. the overall effect is very small and calling it "catastrophic" is exaggerated.
I didn’t even look at the new images until Scott released his inevitable take on it and boy was I not disappointed. I guarantee nobody else found multiple images of the “space cliffs” and slowly zoomed in to reveal the location and context. Top notch as usual.
So amazing to think we have only a few images and they are already next level, and soon we will have thousands and thousands for years to come!
When you put the Hubble carina nebula and the Webb one together Hubble’s looks more like a painting while Webb looks like a render with how detailed it is.
15:32 The comparison of the portion of the Carina nebula was with an image from the La Silla European Southern Observatory, not Hubble.
@@dl5244 I know, I was just pointing out what i found on my own, sry for the confusion.
I've always thought Hubble images have a sort of renaissance look to them.
It was so awesome to see these new images. I really hope that we get an updated Pillars of Creation as well. That, to me, is pretty much the most iconic of Hubble images.
Yessss and those proplyds of the Orion nebula too ! And Eta Carinae ! Imagine what that would look like from the mid infrared instrument of JWST !
I would really like to see the JWST take it's own images ! No more re touched Hubble photo's it is not good science to photo shop an image and lie to people , I want to see unique and new images , with much less of the gravitational lensing , that by it's self shows me there is a huge problem with JWST .
@@timc333 Gravitational lensing isn't an effect added by JWST or by processing the image. It's huge galaxy cluster *bending space time*, providing a magnification of galaxies behind the cluster! It's beyond my comprehension too, but it's not a problem with JWST - rather it shows its mindboggling capabilites.
@@luppenkogropbas5163 Yea I don't know , I am considering that just maybe I am not able to fully understand the images yet , maybe it is as you say just a bit beyond the minds ability to fully comprehend . I still find my self rather bothered by the image . I will say it is my understanding that the infrared equipment onboard is the most powerful and highest tech of it's kind ever designed by man , so maybe the visual images will be of little use other than to paint a nice picture , maybe the real power of JWST is the infrared capabilities , and there the powerful computers are still gonna have to decipher a visual image for us to understand , again time will tell , I hope for big things but I must also say I am still very biased to Hubble , still am strongly in love with Hubble (HST)and still believe in it .
@@timc333 It is not beyond the ability of the mind to understand spacetime. It requires only a little training.
The JWST is basically a photocamera: It records the image of what is there. It captures photons. Unlike most cameras it records in the infrared and more than just three wavelengths. But it is still just an image.
What that image shows is the interesting part. You cannot see in the infrared, so you have to select the frequencies you are interested in and assign them colours that you can see, and you get a visible image showing dust, stars, galaxies, nebulae, whatever there is where it is at.
Alternatively you pick a point and look at the entire spectrum on a curve. That tells you what is going on in that particular spot.
Also interesting is if there are any changes over time.
Now, where you see something is not necessarily where it really is. Take a mirror for example: It shows things where they are not.
Gravitational lensing is similar. Light coming from a certain direction could have been bent, like in a lens. That's the "lensing" part of the name. One thing that bends light is gravity. That is the "gravitational" part of the name.
There are several ways to explain how gravity bends light, and I don't want to go into that. Suffice to say that time progresses at different rates at different points, which is unintuitive, but the acceleration this causes is gravity, and the speed of light is a universal constant, so the only acceleration it can experience is a change in direction. This is probably more confusing than it should be.
The upshot is that light going around huge masses, like black holes or galaxy clusters, originating behind them, gives you several distorted images from different perspectives of the same (originating) object. You get to see things you otherwise wouldn't in spots where they actually aren't. All because a massive clump of matter somewhere in the deep sky that is most likely not directly visible itself.
Hubble ultra-deep field is the most awe-inspiring thing I've ever seen. I've been so excited for the JWST for so long, but also so worried that we'd never actually make it here. I'm beyond relieved that things have turned out so well, and I'm super excited for the coming few decades of amazing astronomy Webb will provide us!
Also considering that JWST took its deep field in 12.5 hours, not several weeks like with the Hubble UDF, many more interesting results will be found going forward
Can't wait for the JWST real deep field with 2 weeks exposure
Hubble ultra-deep fake
@@breakalegfpv9532 Good job exposing the global conspiracy! Amazing that you can get the truth out, what with a worldwide cabal controlling absolutely everything we see! Weird that they're not blocking your Earth-shattering revelation.
@@breakalegfpv9532
I literally haven't watched any other videos analysing the data because I've been waiting for Scott's analysis. Never disappoints.
Locating the last image in space and explaining it was mind-blowing
Best part of the video for me too
timestamp?
@@bobguy6542 14:20
its so fun believing!!!! I love CGI and photoshop!!!! 🐑🐏🐏
What's cool is seeing space telescope images of objects you have seen with your own telescope (granted in much lower resolution).
Can we just appreciate for a moment how Amazing his videos are
Absolutely not.
@@xMorogothx 😐
@@xMorogothx black hole gang disagrees
@@maximum-trollage 🤡
We do appreciate them, and have for a while now
Loved the quote “good science and beautiful imagery are not mutually exclusive concepts”. Thanks Scott!!
science is photoshop? hmmm weird....
Love that too! There is incredible beauty in the images.
Please keep explaining these Webb photos. I felt like a kid in science class again when you were explaining the cosmic cliffs. Great job on this video, thank you.
its so fun believing!!!! I love CGI and photoshop!!!! 🐑🐏🐏
I've been waiting for Scotts take on these images. He did not disappoint.
Yeah, me too, and it was better than anyone else I have seen so far. Seeing both the Hubble and the JW pictures side by side provided much more context. And showing where the Carina nebula is located and old pictures of it before JW, made my jaw drop. Thank you, Scott. I have a much better appreciation for the JW telescope.
Beautiful. Really hopeful they'll greenlight LUVOIR now. Would love to have a telescope like this for visible light, too.
I've always wantes to see space pictures in visible light. I suppose it's more difficult to capture and probably holds less scientific value
@@TitaniusAnglesmith You're right that it holds less scientific value, but some of the colors do exist in space and is just as beautiful. Like our own Milky Way. If you went to a completely dark area with no moon, no clouds, no fog and no light pollution while the Milky Way was rotating right above the point you were standing on, you can actually see some color to the Milky Way, and it's HUGE. Truly a beautiful sight, but it's rare to be able to see it since all of the light pollution in today's world.
@@ET-yc4wb Oh I know, I live in a isolated area. But up close would be cool, even if alot of the image is dark and "uncolourful" compared to the IR images.
i've watched a bunch of these and zoomed into the zoomable pictures for some time. scott is _always_ the best at pointing out facts that everyone else seems to miss. the format of his videos makes the time fly by as well because they're so well thought out.
Imagine being on the comittee deciding the calibration and first images taken by JWST. "Hmm let's see how severely we can stomp Hubble's deep-field images, and let's point it at Jupiter- Oh! Let's measure the atmospheric composition of an exoplanet!"
I know they went through all the systems, but the amount of different observations this thing made in it's first steps as a juvenile space telescope is pretty wild.
man you got taken for a ride. its all photoshop and CGI sorry to burst your bubble
@@Justin-yp1dz Well, as a CG artist, I'm very impressed by the result ;)
@@fiveoneecho you should be with the budget that they get.
Scott has a way of explaining things in his own way making interesting correlations that few else do. Must be from his DJing background and having done this for years. He's a good storyteller weaving in the data and concepts.
Thanks for reporting on this Scott as many people still cannot understand the significance of this telescope or how even color correction is used.
That's because most people associate "infrared light" only with "TV remote".
The fact that people build this amazing device makes me so happy ☺️
Don’t put too much faith in science so-called or humans in general
Wow, the difference in image resolution is amazing. That first side-by-side comparison just blew me away. Can't wait to see what JWST puts out in the future, it's gonna be a ride.
I became passionate as a kid about space thanks to Hubble. I love to see how many people actually started asking questions and are been amazed by space. It was a very necessary upgrade to get more people educated and passionate about the universe and science!
I’m just really happy that so much time, effort, and money, went into something, and it all just works out. Seems like there’s a lack of good news lately, so it’s nice to see that the JWST is working as it should.
Scott, THANK YOU! The recent images have RE-SPARKED my love for the beyond! I’ve been obsessed with the images and have been seeking further information. You explained this VERY WELL. I can’t wait to watch more!
This is the first vid I've seen by you and it was fantastic! I love your enthusiasm for space. Gonna have a full on binge of your content tonight. Great work man
This. This is why I love astronomy and space exploration!
The best summary video yet. Love the new images I hadn't seen - so cool. Thanks Scott, you're the man.
Superlative work on this. The comparison and context images really landed. Thank you.
Amazing video! I’ve been waiting all week for it. Definitely worth the wait. Great job.
Wow Scott!! This is by far the best explanation of the new JWT images. Your presentation is absolutely fantastic. Thank you so much for the effort you put into these!
I've been waiting for your take on the new photos! What a time to be alive.
I've seen two or three space-expert descriptions of these first JWST images, and Scott's is the most detailed and informative. Fascinating stuff, and great depths of discovery still to come. Exciting times.
This was amazing Scott, especially the shifting back'n forth between overlapping images - thank you!
thought I'd go to sleep, but first this
Yeah, Scott. “Good science and beautiful imagery are not mutually exclusive concepts.” There should be a an inscription of that on some building at JPL or NASA. Really looking forward to more of your insights on this. I hope it gets shown to lots and lots of kids.
Thanks, Scott. Your vid has provided the best description and explanation of what - and where - these first images are showing us. Well done, and thanks again.
That's exactly what I thought when I was looking at the southern ring nebula, I ended up trying to spot all the distant galaxies and comparing between NIRcam and MIRI. I am very impressed with the JWST results.
I’ve watched a lot of videos on the JWST (probably too many) and your’s is the best at explaining the science of the images. Thank you!
Scott Manley and Anton Petrov are my two go-to astronomy popular educators by far. Just like Scott Manley and Tim Dodd are the two best when it comes to rocketry.
This must rank amongst your best videos. Thanks for the image explanations, and all the science!
Gooooooosebumps. I've been waiting for your first analysis of these images; your excitement is audible Scott. Going back for another watch, possibly at a slower speed! Like many of us here, I have followed the JWST project for many years; interrupted my Christmas to watch the launch (best present EVER!) and if this is the quality of the very first results then we're in for some spectacular science from this fabulous instrument. Please keep bashing on about JWST Scott; you have a unique angle that makes learning so enjoyable - thank you.
Having Scott Manley as my new daily news host is something I can get used to. Excellent videos as always!
15:24 I trust Scott’s commentary so much that I actually questioned myself about what the definition of “Top Right” is 😳
Amazing explanation, not dumbed down but not overly technical, excellent didatics. Definitely one of Scott's best videos that I've watched!
I've been avoiding breakdowns of the images until you posted yours. Thank you.
Awesome introduction to the images that doesn't talk down to us. Your explanation at the end about false colorization is spot on -- they are not just converting the images to something we can see, but the added colors let astronomers process the image using the part of the brain evolved to understand visible light!
*indoctrination
This images are showing us how the entire reality really is. Technology is made from refined materials and small structures, perfected to the limits by the best experts in sciences and industries, so who cares how much something like that cost. It must be done if it can be done, everybody wants to know what the universe, life and everything actually is.
@@aemrt5745 just align n find the passionate billionaires who truly cares!?!!
u sound just like a wizened soul i come to know n love!?!!
Absolutely stunning, and Scott's enthusiastic commentary adds to the majesty of these superb images.
Thanks for producing this video! Since NASA’s live stream, I’ve been looking forward to your analysis!
Great recap! Magnificent what we have accomplished! Thank you!
Oh my god so exciting, so amazing. There is just so much that we are going to be learning w/ the JWST.
*Scott* - Do you suppose that we will be getting a picture of the Pillars of Creation in the Eagle nebula anytime in the near future? The picture of the Carina nebula is impressive but the Pillars is the most favorite space picture of all time for me.
@@mrsam9206Lol, are you being sarcastic? Why would a satellite image need an editing room? I’ve never heard of a ‘star constellation expert’ before. I don’t know anything about whatever procedure a new sat image progresses along to go from its capture to public release, which is little enough to make me have to question the validity of your comment. Don’t lie to me now, I really really would LOVE to get a new pic of the Pillars as the one Hubble took is still breathtaking. I can’t imagine what kind of details we might be able to see with the JWST.
That was terrific Scott, worth the wait! Thank you for the excellent breakdowns and I liked the little bonus correlation with Space Engine for the Carina Nebula.
Thank you Scott for the work and effort you put into your videos. You always manage to make complex topics feel accessible and digestible.
Thanks Scott! We US amateur astronomers ( and tax payers) are VERY proud of JWST.
Web was paid for by many more than the us....
It took a while for JWST to reach this point, but man those images are glorious. I'm so looking forward to what this marvel of human ingenuity can achieve in the upcoming years
Been waiting for you to talk about this. GOOD STUFF!!
Thank you for the overview and I loved your simple explanation on the reason for the spikes on the stars.
NASA Video: Scientist drooling and staring at the images while sounding like an infomercial without giving me anything I can really understand ...
Scott's Video: Useful information in a format I can understand and actually explain to others...
I really appreciate you taking the time to show the relative position and size of some of these images with the models. I wish everyone did that.
👏👏👏! I absolutely agree!
A question I've always wanted to know is if an alien race had our technology, could they discover us? So seeing these images, how close would an alien's JWST have to be to detect our atmosphere?
they would have to be in our orbital plane so they could see the Earth transit the sun, and they would have be looking at the right time of the year, and then they'd detect the spectra of CFCs and other manmade stuff in the atmosphere and they'd be all Life!, WTF???
Yes but they would have to be within about 100 to 150 lightyears away. Basically we can detect the make up of other planets atmospheres and see if there is unnatural chemicals that can't form without large scale industry.
This video from Cool Worlds channel called "Are Alien Lurkers Watching Us?" will answer your question in detail. They discuss how large your light collecting mirrors would have to be to see a slug or a city or a planet etc. ua-cam.com/video/pwTYfI9JUl8/v-deo.html
Here's a similar video, also from Cool Worlds.
ua-cam.com/video/G71yqev301Q/v-deo.html
@@kadendusk That's right. Any further than ~250 lightyears away and they'd be looking at the Earth as it was before the Industrial Revolution. Of course, given a long, long time our 21st century atmosphere will be visible from galaxies far, far away using a JWST-like telescope.
@@kadendusk Edit: I was thinking of 'us' as 'life on a planet, not civilization, sorry for confusion.
I think the 100 Ly thing will be changing with JWST. If you can spectra 4 forms of water that far away then surely methane and company aren't out of reach.
Well worth the wait. Thanks for your input Scott.
Now this was worth the wait. Finally a decent video with good explanations and even better comparison photos. Well done 👍
Scott, you are a brilliant and unapologetically enthusiastic science communicator! You connect the dots of the near infinite celestial canvas with grace a glee. Edutainment at its finest!
"Nebulosity" just became my new favorite word.
This is huge! Looking forward to your explanation of gravitational lensing in the deep field picture :) it is mindblowing
What a tremendous job Scott did on this video. Between the layman explanations and the excellent editing, I feel like I actually understand what the images were really showing.
They could get rid of the diffraction spikes by rotating the telescope 30°, then doing a second exposure. Then eliminate anything that isn't in both photos.
JWST roll limits are +- 5 degrees
LMAO awesome first reply!
Kinda a waste of rocket fuel just to get a pretty picture.
@@scottmanley Then do it six times. 😂 Just kidding.
@@Theoryofcatsndogs Isn't that the whole point of JWT? To get pretty pictures? If galaxies within the image are blocked by the spikes, then it would make sense to do what I said (if it would have been possible). :-)
these images are just amazing
and so efy BRIGHT ! geezzz ... JWST will be able to see even Pluto with those ultrasensible sensors
Awesome break down of what we are seeing Scott...!!! Thank you ...!!!
The PR crew at JPL did such a good job selecting and explaining these first few images promotionally; most people just have absolutely no clue (nor do they care) about the science you've explained here, but a few quick glances at the slides they provided are indeed spectacular, even for a layman. Kudos to them for pulling in everyday people and (starting to) justify the extreme cost. As a general science and aerospace nerd, I was keenly aware of the complexities of Webb, but it's great to see JPL / NASA doing a good job reaching out to the general public and getting some attention in the news, they definitely deserve it.
The idea of billions of stars in millions to billions of galaxies is incredible to me, and seeing those images just helps a tiny bit on wrapping my head around that. The vastness of this all makes me wonder why we need wars and other conflicts here on earth. We have such a rare thing here, can't we all just get along?
@Cancer McAids Webb will be able to map asteroid targets for future mining.
@Cancer McAids No. But by the time it runs out, some other way may have been found.
Nice explanatory video; There should be 20+ more years of interesting material from JWT coming. Honestly, Hubble did massive overtime to date, considering its inauspicious beginnings (kudos to that team).
Question - What was that software that was used to 'travel' out to the nebula? Looked like an interesting spatial mapping system.
He says the name several times - Space Engine.
@@Safetytrousers The problem is that "Space Engine" sounds like if it was the technical "generic designator" for the "kind" of program/game he is using (rather than a proper name).
-> It would be different if it was called "Stellae Simulacra" (or something like that).
I was waiting for what I knew would be the best explanation and analysis. Scott, you did not disappoint. Excellent work again!!
Beautiful photos and great explanations! Thanks so much!
One thing that no one has done to help people get the scale of the structure at Carina is to compare the "2 light years" scale with the distance between the sun and Alpha centauri.
JWST: Giving us the ability to enhance our desktop wallpapers. 15:56
This is an absolutely wonderful discussion and explanation of these gorgeous images. I will show this video to my Astronomy students.
Love your work Scott thank you for both educating & keeping me up to date with all things to do with space & rockets. Thanks my friend love & light to you
Scott, all due respect to NASA/ESA and all the other teams involved, but they should have had you do the reveal - this is SO GREAT! TY for the wonderful video!
Where _not_ to do the reveal? The White House. With all due respect to politicians, what do any of them know about astronomy or cosmology?
Thank you for finally pointing out that none of these JWST images are or ever will be optical. The problem is popular media doesn't understand this and a pretty image is beheld by the eyes, even if it is enhanced to be optically understood.
Technically, depending on the redshift some of the images are optical in the reference frame of the source.
Best coverage of this image release so far. Well done!
Thank you for your insight on this. Great video Scott.
"You know... Science!"
Ok... I don't even doubt for a second that those were his exact words.
Thanks Scott, this was the video (and explanation) I've been waiting for since the initial announcement of the first images.
Been waiting for something about JWST from you!
After all the doom and gloom that I was forcing into myself to not be disappointing... I was not expecting that. It's really impressive! And I think it can still do better?
Well done Scott! A great summary. I'm old, and while I've cherished my life as I've watched and participated as the space and technology eras have unfolded, I wish I could live decades longer to see where it all leads. What will we know with greater certainty in 20, 50 or 100 years? Amazing potential.
Awesome description and breakdowns here!
You sir are a legend and a treasure! I have been waiting for you, Astrum, and Cool Worlds Lab to comment about the JWST "test images". You are an amazing science communicator! Thank you
Mind boggling that humans can launch a semi autonomous robot that far into space without something breaking.
And with just 3x cost overruns and 10 years behind schedule.
@@juhasznagyjozsef At a previous employer, they had a motivational diagram in their workshop office:
"you can choose one of 3 options:
1) Do it well and do it inexpensive --> No problem, but it will cost time
2) Do it well and do it fast --> No problem, but it will cost you
2) Do it inexpensive and fast --> No problem, but it won't be working very well.
Just the difference of knowing 8 weeks in advance you need something, or just figuring it out last week can add so much extra costs and disruption on a program.
@@Tuning3434 Sounds like that's just a long-winded way of saying "Good, Fast, Cheap: pick two". 😁
I've always wondered how they are able to tell how red shifted things are due to the dopler effect. I get the idea and concept but how do they tell the difference between hydrogen and another element if it has been shifted enough to match another element?
As I understand they don't Look only on Hydrogen but also to Others Elements (atleast Helium) and so you know die differents between Them.
@@mariankerler2134 yeah, it’s about the ratios, and the resonances (eg there’s always more than one spike for an element, and the specific resonant period to the next spike differs between elements). But some are certainly very close together like tungsten and gold. But still easily discernible if you’re expecting it.
The pattern of lines is very specific to the element, because it depends on all the electrons in the atom and the distribution of electric charge they are moving in. And if the atom is part of a molecule, that will affect things as well, especially when you get way into the infrared.
I'm not an expert, but I'd say it's because there are known patterns. Even one element has multiple lines of emission in a particular configuration, and elements will have fixed positions relative to each other. The degree of red shift of an object is only a single parameter. I've not done it, but I shouldn't think it's very difficult. I suspect those familiar with it could look at a spectrogram and immediately spot known emission lines without looking at the x-axis.
Beautiful video, thank Scott! Finally comparing Hubble and Webb images and commenting/explaining them. Scott you are the best!
Stunning. Thanks for explaining so clearly and in such an entertaining way. Greetings from back home in Britain
you're one hell of a content creator Sir. i don't know how long you took to make it, can't be very long as the photos just got released but i'm impressed. nice job. you and Musk ought to get together and discuss your common interests.
One star in the "cosmic cliff" looks more like a comet, with a tail only on one side. I wonder how that happens? Maybe that star is travelling through the nebula at high speed and wasn't part of the star formation there. I hope I hear about that one some more in the future.
Thank you for sharing your wonderful photos and hope you have a blessed week ahead 🙏🌎
Awesome job explaining the very complex scientific aspects of these new and updated images! New subscriber here 👍
Can you make a vide comparing all sls blocks;s (1, 1b, 2) thrust, power, and design with other superheavy rockets? I have seen other videos on the internet comparing 1 to 1b but I would enjoy one of all the proposed concepts. I know it is unlikely for you to notice this but I thought it was neat.
qq, has anyone mentioned how the meteor impact to one of the mirrors has affected image quality? Looking at the images we have, seems like it was not a big deal
If you go to Dr. Becky Smethurst's videos you will find an analysis of that impact. In short, this is expected and can be calibrated against for the predicted scope of impacts.
It was a micrometeorite. A meteor impact would have completely destroyed the whole telescope.
