Designing Webb

- The James Webb Space Telescope is the most powerful space telescope ever made - and the most complex one yet designed. Did you know that the telescope’s history stretches back before the Hubble Space Telescope was launched? This video explores the various early concept designs for Webb, including the criteria and the players. Learn more about Webb’s final design, how it evolved, and how the completed telescope was tested and prepared for its historic launch.

The amount of engineering involved in Webb is insane, really astonishing.
It's an amazing work of design, engineering - and imagination. Imagine having to figure out how to build, launch, and implement something unlike anything ever built. It's an amazing technological achievement. ❤️
Notification astrophiles, assemble...
Of all the channels I wish uploaded more, it's this one.
✨
It's such an incredible designing process! I hope to see and listen more about this amazing work. Thank you JWST!!
A outstanding piece of hardware. I can't wait to see what the JWST will find about the universe in year #2 of its history.
This is so interesting to see the process over the years! 👏
I was lucky enough to work for the company that produced lightweight carbon fiber materials for this project. I did the quality testing on the materials as they were being produced and ensured that they were within the specified parameters. Even though this was just a small part of this amazing project, I am still very proud of my contribution to this amazing scientific project.
2:47 While cameras are great for creating an image (wall posters and target identification) the actual science is done by spectrometers. The MIRI instrument is the real engine of discovery since it is looking at wavelengths which are blocked by the Earth's atmosphere.
Finally a good video, more like this please!
Fantastic. Thanks.
Simply awesome engineering
Thank you for sharing, super- fascinating!
Note to self: TRW's E2 on 1974 postcard at 4:24. NGC's E2 at 7:39. JWST in NGC's M8 at 9:46 & onward.
Magnificent
Thank you
Special eyes.
How does a typical Webb 12bya IR picture compare to the Hubble UDF, in terms of coverage of the sky?
this is one of the best webb videos I've seen, and I've seen a bunch (I worked on it too!)

Hey guys, JWST is already in space …
Yes, this is a documentary about the early history and design of JWST and how we got the final version.
Sure, and WWII is over and Ray Bradbury is dead, so I guess there's no reason to discuss either of them. 🙄
@@TheStockwell What??
Once again USA/NASA has delivered a giant leap for mankind.
NASA indeed did some truly badass stuff for this, but the Canadians and Europeans made enormous contributions too. Besides sensor and focus packages from both teams, ESA (via Arianespace) delivered Webb on a launch so perfect that it literally doubled the mission lifetime of the telescope.
I think that it is very strange that we are not using the JWST to look at exoplanets much closer to earth. Why are we allocating 90% of its runtime just to look at extremely far away objects? I know recently JWST observed the TRAPPIST1 system... but there are so many other exoplanet canidates much closer to earth than somthing several billion light-years away.
Researchers all put in bids for viewing time. The winning bids are chosen on what gives the best science. There are far more things to look at than exoplanets.
There are plenty of opportunities coming up, about 20+ years actually. It's actually really not the primary objective of the telescope, which is to try to observe galaxies in the early days of the universe. Before Webb, we had this huge "gap" between the CMB (the first light of the universe when it began to expand) and galaxies that were already formed. Because of that gap, it was difficult to get an idea on what was happening between that time and how galaxies formed. Closing that gap gives cosmologists a better idea on not just how the universe began and grew, but how it may die.
The second most important objective of Webb is to understand better how stars form. Since stars at their infancy are cloaked in dust, it is hard to see how they form until they start being energetic enough to blow the dust away. Mid-infrared light easily passes through the dust, allowing the very beginning phases to be seen, where the dust is clumping together. Observing this in better clarity can confirm, deny, or even cast doubt on what we currently know about how stars form and how planets themselves eventually form.
Scientists have already seen and studied enough exoplanet systems to determine that our system is a fairly rare outlier, and many we know for a fact already would be unable to support life, but the ones that are questionable or that we have a good idea on are getting priority.
To expand on the cosmology part, currently science that applies well in large astronomical objects doesn't work well on subatomic levels, and vice versa. Closing that gap might reveal a bridge between the two sciences that would work on both levels. It's unlikely, but you never know what is in a hole until you look into it.
