[@danilooliveira6580]

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.

[@carlweaselbear534]

Wow that's awesome. Thanks for the information. It's really interesting and exciting the more I find about this telesc

[@millicentduke6652]

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

[@JWH3]

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''

[@solsystem1342]

@@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 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.

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**

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.

[@Heistergand]

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?

[@santyclause8034]

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.

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.

[@ravinereedy204]

@@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.

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.

[@listerdave1240]

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.

[@stevepower6616]

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!

[@MrT------5743]

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.

[@yasminesteinbauer8565]

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.

[@MrT------5743]

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

[@beta_cygni1950]

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.

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!

[@beta_cygni1950]

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.

[@cwehbe]

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?

[@JWH3]

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 :)

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.

[@douglasboyle6544]

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.
