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 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.

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.

The data that is collected by the Webb in 1 years will take 20 years to fully analyze. The data from the Hubble that are converted to images you see today is years old.

[@RedRocket4000]

Because those first galaxies are so far red shifted we might not have a good idea of their true shape which might be redshifted into inferred. What I'd love is finding galaxies way to far away and way to organized to match current ideas just to blow everyones minds. Wish I wrote down the name but one of the key scientists in coming up with dark energy idea did postulate that it instead is a yet to be discovered field (as in Quatim probably) in intergalactic space that is absorbing energy thus causing red shift instead of Galaxies moving away from us at least partially. As we can't observe expansion of the Galaxy in the cosmic voids and it does not occur inside or near Galaxies we are dealing with an unknown. I just having fun current ideas more likely right than wrong but it would be fun.

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''

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?

[@johninni4844]

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.

@@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.

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!🔭🔭🔭🔭🔭🎬♾☮️💟🌈😻🥰😘🤯🗽

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!

[@esquilax5563]

L2 is also much closer than L4/L5 (1m miles instead of 90m), so data transfer is easier

[@Gerald0613]

best I can tell it's a spasm between L4 and L5

[@RevDeathYT]

Main reason for L2 is shade from earth

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.

[@THIS---GUY]

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.

[@_HMCB_]

@@THIS---GUY thanks. I’m going to track down SEA today.

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.

[@ravinereedy204]

@@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.

[@philipsmi-lenguyen8155]

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. 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)

Seeing somebody let their passion and excitement shine so brightly while teaching - especially in the sciences - is so wonderful. Fantastic video, Dianna (and team)!

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.
