🔴More on Webb's instruments! ua-cam.com/video/MzWfUK0yvdY/v-deo.html
Cant wait for new galaxy and new star count
Can you explain in a different way what it means that the starlight is diffracted off the instruments? Does that mean it might hit a mirror and some fraction of the light will not reflect into the target area?
Also, when talking about one of the imagers capturing the position of a guide star once a second: what format is the stars position reported in? Can you explain a bit more about how the instrument uses a star to know it's position in space?
I discussed diffraction at some length in my video on the mirror alignment. Perhaps that can help? ua-cam.com/video/cWXTy_GeCis/v-deo.html
I plan to discuss how Webb points and holds its position in an upcoming video :)
“It’s working as good or better than expected “. The scientists of today have built on the successes of past masters to become incredibly smart. This telescope is an astonishing feat. Bravo.
Building on the shoulders of giants... who built on the shoulders of giants.... who all felt just as small as us o0
@@sobreaver Imagine if their wasn't a barrier to entry (tuition) to higher education. We could be even further along than we are now
@@Tburge212 I understand the 'system' isn't 'perfect' (and nothing is) but although pain, obstacle and challenges can be hard for anyone (and a fkin hassle to deal with), let us not forget the important role that such displeasing plays into the growth of ABSOLUTELY everything. Sure, we could always debate with lil ultimate proof that those 'challenges' are Really necessary to the 'growth' but I must say, most of my illuminating realization in my life, small or big - to me, came from such obstacles, hindrances and discomfort I somehow, and to a somewhat degree, managed to overcome. So up to a point, a reasonable and hard to determine in black and white binary threshold mathematical limit, NO PAIN, NO GAIN is a common rule for what we sometimes perceive as beauty in this universe ;)
You will notice actual comparisons with a couple of lower res telescopes but not the Hubble. Hubble has a near infra mode and I would love to see a direct comparison of the 2 looking at the same Galactic cluster. No doubt the Webb would see better through the interstellar dust but where that's not a issue I'm missing the clarity and snap of Hubble shots when looking at the latest Webb shots. Maybe after it's fully cooled. Sooner or later they will catalogue one of the same regions as the Hubble. Then true comparisons can be made. As they say size isn't everything.
@@eleventy-seven No no, size do matter :P
And in the case of the universe, size can actually be EVERYTHING ! =]
First this and now a new pic of a black hole! This is truly an exciting moment in history
This video is NOT CLICK BAIT!
This is the first JWT video I've seen that doesn't talk about what it can do but rather what it is doing... And you do an amazing job explaining it!
Thanks 🙏
Indeed, so many click bait crappy videos out there telling us "JWST Finally..." only to have just another boring intro
@@geedon1 unsub and forget the channel existed
@@geedon1 or “IT JUST HAPPENED” “ IT FINALLY HAPPENED” and that script.
Actually it is talking about what it is failling to do
We can't help but reflect on this incredible accomplishment.
Hahaha
I see what you did there. lol
_Oh, and allow me to add... evidently, early reports are claiming the Webb Telescope is out of this world._
Please, do not slam the door on your way out...lol...
Haha! Good one!
o no u dinnint!
This has become my go-to channel for Webb updates. Love your videos and way of explaining.
Thank you so much, I'm really flattered1
I'll go to your channel
@@GraveyardTricks that's great little buddy☺
@@LaunchPadAstronomy Cool.
anton and becky are also worth mentioning, but this channel really gets into the nitty gritty detail
I'm so proud of the engineers, the designer's, everyone involved in this, in coming up with ideas and creations. The technology, the concepts, are such great ideas, I can't wait to see the science that comes from this.
Your praise is misplaced.
@@mysticnomad3577 Your is is mis-spelled.
@@kumasenlac5504 thank you.
I have edited the correction.
I agree, proof read everything.
bla,bla,bla, and we are still here without seeing an alien, another life form, another planet with life, another starship beside the Elon musk roquet.
@David Mackey COOL, LOL.
I am full of wonder looking at these stars and galaxies. It actually brings tears to my eyes to see the accomplishments I’ve witnessed over the last 60 years. I was young but I saw Neil Armstrong take that magical first step on the moon. I was hooked.
Thank you all for all that you do and have done in my life; and all you will do in my grandkids.
Thank you for remaining so factual and level headed about the information, as well as pulling it all together so accurately. So many channels are click bait and discuss absolutely nothing relevant to what's been found. You're by far the best channel to come to for updates on JWST. Thank you
Thanks, I really appreciate it!
Biggest complaint I have is that it is hard to see some of the details of the images on mobile. Blowing it up to the size of the screen, maybe scrolling between the two (better 1, or 2? 3 or 4? Eye doctor style), maybe sliding between two pictures with the same field of view, half and half, then sliding the dividing line left and right, maybe zoom in on the detail of the spectrograph to point out the spectrum lines.
Those things could help those of us with 6.5 mm apertures, not 6.5 m ones!
Those images weren’t full res either. The full MIRI image was released the other day though.
It's beautiful. Everything about this is just beautiful.
My sentiments exactly. It's a symphony of the human spirit.
@@xyzct Yes and this is just the baby steps
It’s beautiful! WOW. It’s amazing!…. Your getting the horn over pictures? It doesn’t matter how far you look, all your see is repetition. How do these pretty pictures help humanity find it’s true nature?
@@miniadventureswithmark3309 Umm what kind of hippie BS is that :D Engineering is beautiful too. Just the proof that we can build machines and devise tests to discover things about nature of reality is amazing enough. Human nature is about discovery. By discovering new things we can try to improve our lives. Sometimes it works out sometimes it doesn't but that's what makes it exciting.
@@miniadventureswithmark3309, humanity doesn't need to "find" its true nature. This is it! THIS is humanity's true nature -- curiosity, exploration, innovation, teamwork ...
You must live in a pretty dark place if you can't see the brilliant light shining from this mind-boggling effort.
Love it!
It's strange to me that mainstream media is so focused on death and destruction, gossip and rumors. Weather and sports are all they are good for. The real game changing news must be sought out and studied to actually gain knowledge about the world and universe!
Thank you, for sharing your knowledge. You have become a part of my regular rotation of CREDIBLE information and have earned a new subscriber.
Also, this comment section is awesome. No negative energy or complaining people.
Thank you! I certainly try my best to get it right. As for the negative types, they’re around but pay no mind.
The reason mainstream media is so focused on the negative news is coz it sells and good news does not lol
The fact that this telescope even works is just bananas
It's almost hard to believe that JWST has launched and is deployed. It always seemed like something that was going to be continually delayed indefinitely. it's really nice to see that it appears to be operating properly, as I'm sure that was the nightmare of the engineers and part of what added to the delays... 'cause once it's out there, there's no way to fix it.
Totally 😊, "it's really happened..."
@@woodwardjr yes we watched it like live 😀
When I was young and impetuous, a wise old man told me that time spent in preparation is never time wasted. Measure twice, cut once!
It really is amazing. I've been waiting for this for so long and it's finally up there. Hard to believe for sure
Sure! They would never repeat the same mistake that was made with Hubble telescope. Because once it's in the orbit no way you can fly to it and fix it. Like they did it with Hubble. They wanted make sure that Webb performance is beyond expectations. Period!!!!
Its nice to know that space, is far more beautiful than we could have ever of imagined. Thanks to the scientist, engineers and technicians, that brought us the JWST.
So hard not to watch this video right away.
Saving this as a reward for later tonight once I get all my things done. Thanks so much Christian, you know we've been waiting for this video!
Thank you! I hope you enjoy it.
I'm happy to hear that the scope is up and running smoothly. Now I'm looking forward to see what this telescope will show us.
Youll never see the truth Yogi, from any official gov backed entity.
You pulled me in with the Dave Bowman quote. Well done.
I'm so relieved it is up there and working. I can't imagine the anxiety for the people who worked on it. I'm proud of and happy for all those involved.
I stopped tracking new updates about Webb for a while ,so that i can be more excited by knowing them in far more detail ,on your videos ... totally worth it
Thank you very much. Sorry it takes me so long!
@@LaunchPadAstronomy please don't be,cause great things come at the cost of time 🤓
I'm so tired of clickbait video about JWST, I'm glad there's someone like you who actually talk about the real stuff
Thank you, I try.
As an Army Infantryman it always fascinated me just how many more stars that I could see using Night Vision Googles. Mind you this is without magnification, but able to pick up light sources that the naked eye could not. The sky is COVERED LIKE A BLANKET with countless stars in every part, hundreds if not thousands of stars for each one you can see with the NVG's.
To say "We are not alone" is the underestimation of ALL time.
This is the first presentation of Webb that succinctly explained reasons, etc. for the time involved that makes sense and other anomalies. Thanks!
All straight facts/details laid out systematically and quick explanations with zero math?
You make it easy to follow your presentation.
Subscribed.
What's bad about math? Are you in public school?
@@vomm Math doesn't show much in terms of visual explanation. And it wasn't my favorite subject in school.
@@edinfific2576 well, to be fair, numbers can say more than words. But I do get that not everyone can understand these numbers anyway.
@@vomm Damn, pretentious much?
I've been waiting 263 years to hear that the James Webb scope is ACTUALLY OPERATIONAL!!!!!
Hooray!!!!
This is the type of news I need in my life, not that mainstream media nonsense
While everyone was staring at the 6+2 spike star in that first ever image, I was stunned by the background galaxy field to the point of obsession. One day I'll count them. Is it the first time we're seeing them? I wonder if any of these are have been catalogued, or are they all beyond our other instrument capabilities? Do you perchance know, Christian?
BTW, you're the only person who gives a lot of technical info about the Webb. Everything else I could find is either too simple, or flies over my head. Thank you so much for this whole series, and please, please continue! I didn't realize how much amazing tech had gone into the design and construction of this fantastic instrument!
Thank you, Cy! Several of the galaxies in that earlier image were identified so they were previously known. Most of the faint blobs in the background are "new" galaxies.
@@LaunchPadAstronomy Thank you, that was what I suspected. I'm sure many of these objects won't fit completely into the current modes, opening a huge field of new exciting work. It's always uplifting to think how much we don't know. I forgot the name of the famous physicist who [in]famously claimed at some time around the boundary between the 19 and 20cc. that physics had been pretty much complete, and there was nothing significant left to discover... :-)
Many Hubble images also feature background galaxies as well. Even some that shine through the stars of the featured galaxy.
JWST first image:
The very "bright" central star is actually a very dim star as seen from Earth. I think it is about magnitude 11. This is more than 1,000 times dimmer than can be seen with the naked eye. It can be seen in amateur telescopes of 6 inches aperture or more.
Summer can't come soon enough!! Look at how many stars and galaxies you can see!
Christian, you are the VERY best narrator for these complex presentations. Thank you for your excellent work.
You are so kind, thank you!
I am so in awe of the Engineering that went into this project.
I was a Professional Design Engineer for most of my working life on what I thought were hi-tech multidisciplinary projects, but Webb makes my efforts look like making flint axe heads.
(Just like the first Engineers.)
Well done!
standing on the shoulders of flint-axe makers....
@@kumasenlac5504 An old acquaintance of mine made flint and obsidian axes, knives etc. for museum replicas and collectors. Watching her work was immersing, especially when she gave me the chance to try my hand using her modern tools. I failed to make anything recognisable or useful while she could use worked stones and pieces of hide to shape functional cutting tools from raw materials in a remarkably short time. Flint axes may appear crude but making them is a skilled process that takes time to learn, preferably from a master who has spent decades previously making them. "Standing on the shoulders of giants" goes back a long way.
@@robertsneddon731 I meant no disrespect to flint-axe makers but simply sought to highlight the continuum of technological development over the millennia. The flint-axe makers built the Ness of Brodgar after all... (o:
As long as it took for JWST to be developed and launched, I’m still amazed because of the incredible amount of engineering and science crammed into this device. How they figured all this stuff out is just mind boggling to me.
I'll tell you how: Science, Technology, Mathematics, Enginerring.... not necessarily in that order, of course. These things get results.
@@photonjones5908 Probably more 'Mathemiatics' than anything.
@@mrbrown6421 just as much engineering
@@photonjones5908 and DMT
Time and money
It is full of stars indeed. I am so impressed by both the engineering and the theoretical science coming together to bring us this amazing knowledge (with the help of Launch Pad Astronomy). The fantastic evolution image shows how fast the technology changes, ... in our lifetime. Thanks for your work!
I am but your humble messenger, but thank you :)
Heartfelt thanks to you scientists and researchers who allow all mankind to grow.
In a world where there is so much darkness, you are truly the brightest lights.
I am sitting here getting goosebumps over how good these images are and then get told "Oh this Webb at its worse" Brain immediately goes to checked out mode lol
Very insightful!
I have the feeling that Webb really sparked a new mainstream interest in astronomy and that is great. the more people, that are interested in science the better.
Finally, let's science together
Let's fighting love
Your first
This is one of man’s great accomplishments, congratulations to all those who worked on this! 👍 Well done.
This is my favorite resource for all things regarding this telescope. Thank you for doing such a great job and for your dedication to great content.
Beautiful! I love the way this is coming together ❤️
I can't wait for the Webb deep field. Thanks for the deep dive on the instruments!
This is some great content! Really love your explanations of everything. Thank you!
I’ve been teaching astronomy to high school students on and off for decades. I really appreciate the loving care and passion this great science educator puts forth in each of his videos. He’s doing important, essential work.
Wow, thank you!
We dont realize how much each of us impacts each other till later and mabe never ! . The more we learn about sensors the more we can do. Sensors and a computer are where its at !. If we can keep from destroying ourselfs the sky is the limit . Mabe even more. Thanks to u my friend we can grasp it a bit.
Your excitement on this topic is infectious. Great video.
Thank you 🙏
Love the "2010" episode title. Perfect! 😊 And your enthusiasm is contagious. An Exciting and Comprehensive Episode. Thank you for the deep info research!
Seeing those incredibly sharp images gives me chills. GREAT Job!!!
This is JUST the beginning. We look forward to more.
This is the most detailed analysis of the alignment and instruments on UA-cam.
Can I just say how refreshing this presentation is over the majority of flashy low substance popular science videos covering this topic?
There is not a single bit of content fat that should be trimmed and it’s still enjoyable to watch.
10/10 subbed
Thank you so much for the kind words, and thanks for coming onboard!
For sure. You still have to share my attention with Dr. Becky, but I think you are in good company there. :)
Your content is exceptionally detailed and to the point. I really appreciate the effort. Thank you good sir.
.....And everything, is done by humans. Simply amazing.
Great explanations, thanks Christian. Can't wait for the DD-ERS to get started.. It's been a long time coming so it's fantastic that everything is working properly.
Thanks a lot for this clear and concise presentation. Much appeciated.
Maybe the greatest scientific achievement in the History of Mankind. The images we are about to see will astound and humble us......I'm so glad to live long enough to see this.
Thank you so much. This type of detail had to take a lot of research from your side. I'm impressed by the fact that all the technical stuff was explained in such a way that even average guys like me understood everything so well explained.
I've been waiting for your insight and explanantions for these images and wasn't disappointed! Can't wait to see what's next! Thanks for another brilliant video this is the most exciting journey ever it's actually happening!
Thanks for taking the time to give in-depth information.
"Let's geek out on it a little bit"
That's what I'm here for, friend.
Thank you for being the first channel I’ve come across to explain what we’re *actually* looking at!
worked at NASA for 20 years...and exceptionally well done video. I always saw Webb as a delayed $$$ sink that existed before I got there and would launch after I left (aka: I don't care, stop burning the budget pls).......but I'm starting to like it.
fantastic video! thank you for clearly explaining such complicated concepts.
Thanks, I'm glad you enjoyed it!
Very beautiful ❤️ Thank you for making this possible to all involved from telescope to this video! Thank you 💓
Finally, a JWST-related video that isn't clickbait. Beautiful presentation.
I am so much looking forward to every one of your videos, they are just so good, well-informed and everything. Thank you for doing this. PS: please nerd out about the cryocooler, I am waiting for it since you mentioned it a few weeks ago :D
Thank you! Re: the cryocooler, that was the video I was working on before NASA released this image and interrupted me :)
@@LaunchPadAstronomy Those NASA guys, messing up everybody's plans by interrupting ... with awesomeness.
The time it consumed in making the JWST ,the launch , the science and technology that is crammed into it ,the astronomical amount that was spent, and the results that this masterpiece of human intelligence is supposed to deliver ,and everything about this JWST simply amazes me. just waiting for it to revolutionize the science we know.
This is an incredible achievement!! The video presentation is fantastic! Fascinating!!
Thanks for the update!
THANK YOU for this detailed explanation!
Wonderful work done and very detailed information in this video
breathless with excitement!! woo hoo!
I don’t understand like 70% of the terms you’re using… but I’m here for it. I’m still amazed lol
best update on UA-cam thank you
Awesome content, awesome channel!
Thank you for sharing your knowledge so clearly, while still providing such high-quality scientific details.
My pleasure!
A lot of it went over the head of a layman like me, yet it was so thrilling to know that things has gone 'even better than expected '.
Looking forward to some great photographs from JWST.
The telescope is understandable in it's entirety to no one. Some people specialize in the micro machine shutters manufacturing, some people in the optics, some people on the astrophysics, some on the digital image processing.
With my electrical engineering background, I see a lot of the semiconductor manufacturing I know a bit about, I also see a lot of the image processing stuff, how to subtract signals, how to quantify "sharp focus" algorithmically, etc, but even then, I am only glimpsing the complexity.
This isn't a achievement of a single person, lay or specialized, it is the combination of millions of people doing their jobs professionally and competently. You gotta mine the rocks out of the ground, you have to build the milling and polishing machines, you gotta operate them, research new micromachines for the shutters. Heck, you gotta have a way to move the data from the Deep Space Network communications satellites to the mission headquarters, you gotta have computers to store and process the data.
There is no way a single person can comprehend the complexity of the economy that is needed to pull this off.
JWST has proved to be a truly incredible achievement made possible against all the odds
Thanks for the exciting information. So glad to know we are now able to get the info from the telescope that we've been waiting for, for such a long time! Exciting, and now, understandable. Thanks!
Sir you’ve explained this in a way that makes sense! Seriously your presentation on JWST is TOP TIER!
Thank you
Wow, thank you very much!
Fantastic video, Christian. Excellent breakdown and explanation.
Thanks Dee! Hope you’re well.
@@LaunchPadAstronomy 11
Really enjoying your delivery and content. Thank you
Very nice explanation of the calibration & alignment process for the instruments.
Re 0:50 I would expect only 6 spikes (not "8") for these are hexagonal mirrors, "plus 2" for the strut, and 6 is also what I see in the video.
CHRISTIAN!!!! Thanks for another informative video!!! I'm always amazed at the technical savvy and "brain power" it took to pull this off!! Your videos are a valuable resource of info and easy to understand explainations!!! In other words, this stuff is cool!!!!
Thanks man!
Awesome post, great explanations, educational, aaaaand so super excited for JWST! Thanks Christian!
That was an excellent breakdown better than anything else I've seen before. Well done.
Thank you so much for this video!! You got my subscription. Thank you for keeping us up to date on what’s going w/ JWT!
Thank you Christian, as if it isn't exciting enough you make it more excitinger! I wish Jerry was here to see our 'eye of the world'.
I wish my guy Carl Sagan was here to see this.
Things like this is why I love astronomy, it makes our understanding of the universe more amazing!
Holy cow... the actual size of those interpixellary areas are SO fine, the notion that they could diffract enough light to cause an effect this dramatic, is a bit mindboggling.
I watched this instead of Picard season finale. Can’t wait for more JWST content it’s freakin awesome
I'm so excited! This is going to be so cool. I can't wait to see what's discovered in the next few years thanks to that telescope.
The science and advancement of the Webb never stop astounding me...
Very interesting. I love how you can explain this in such detail and retail the interest factor! Keep up the good work!
Amazing video ! Great access and your insights are out of this Multiverse!
Thank you, my friend!
It’s just mind boggling how many pieces need to fall into place so that this orchestra in space goes off without a hitch. The terrestrial delays will be worth it.
Btw: Nice 2001: A Space Odyssey reference. Keir Dullea immediately popped into my head.
Glad to see Webb is coming along well. Excellent video, dude.
Michael Keaton, thank you for taking the time to sit down and make this video. This is fascinating, and I really cannot wait to see what discoveries Webb has in store for us, down the line. Also, I really loved you in Beetlejuice.
Hahaha!!! I was thinking the same thing!!!
Keep bringing us JWST updates please! subbed.
Thanks and more to come!
Wonderful analysis, thank you very much!
Your explanation of each video is detailed..
I got impressed with your video.. ❤️
The JWST Team are making Galileo so Proud. Making all his sacrifices at the time well worth it. ❤❤❤ Science. Oh and now I am a subscriber to your Channel. Good work Christian.
Science is awesome! I can't wait to see what we find out from that amazing telescope!
Thank you so much for uploading this informative video. I was a bit skeptical when the video started, because I've seen other channels where they just recycle old Hubble images and claim them to be from JWST.
But this video isn't anything like those. Again thanks.
OMG OMG OMG, this is the best news of 2022!!! Can't wait to see more photos.
