For those unfamiliar with the laser pointing at the sky. It is called Adaptive Optics .It projects the laser in the atmosphere and looks like point star distorted by air turbulence. Because the shape is known the computer calculate and compares the laser image with the distorted star image from big telescope. Then the computer sends corrections to the secondary mirror. Secondary mirror is very thin and has several small electromagnets under the mirror surface like those in a an audio speaker which with the signal from the computer bend the surface of the mirror and correct the image.

Ten times better resolution than four interferometric optical telescope. Maybe, but the ELT also combines all the light into one image. The four telescope interferometer doesn't combine all four to make a single image. They only combine the light for spectroscopy. When they take a picture, they take a picture with only one of them. So, it would be more accurate to compare the ELT to just one of the four optical interferometer telescope.
This is not true. There are imaging instruments at VLTI which can combine interference fringes to get an image - in the past AMBER and MIDI and now PIONIER and GRAVITY can do that. So no, they combine light not only for spectroscopy. But you are correct that it's not a 1:1 comparison because interferometry is not "magic" - not only you don't collect the same amount of light as real mirror of that size, but you also "lose" 90% of the light by bouncing it around into a single focus. As a result you might get better resolution from interferometer, but it will only work for very bright objects. ELT will be able to see significantly fainter objects.

The James Webb telescope only collects infrared light. The Extremely Large Telescope will collect visible/near infrared light. Their capabilities are different. A better comparison would be to the proposed LUVOIR space telescope which will have up to a 50 foot primary mirror and will be capable of collecting visible, UV and infrared light.
@@GRosa250 Hubble definitely took pictures on the visible light spectrum though, and space telescopes avoid any intrusion from the atmosphere of Earth.
Not only does it provide other capabillities than WEBB, but you also need more than one observatory as the sky is big and the number of targets and projects are big. But ELT will also have six times the resolution of WEBB and will gain better results in many areas.
Watch Tom Scott’s video and you’ll learn a lot. He toured the place and gives a very good explanation of its capabilities and differences to other telescopes including Webb. Well worth watching... ua-cam.com/video/QqRREz0iBes/v-deo.htmlsi=ZdiKIncFMCtychfz
Telescopes are not put on mountaintops to be as "close as possible to the stars". One reason they are put there is to get above all the junk that is in the atmosphere such as dust, smoke, and water vapor as possible. The stars are way too far away for a few thousand feet to make any difference whatsoever.
That's a big ole telescope. One thing you didn't mention that I think is really cool is that it's supposed to be able to correct for atmospheric distortion. I don't know exactly how it works, but somehow they point a bunch of lasers at the sky that detect the distortion, and then software makes corrections to the image in real time. It'll be pretty amazing if it works.
This is standard practice now. E.g. the Very Large Array telescopes (not far from the ETL) already use this sort of correction. Tom Scott did a great (what else?) video on it. It also captures the ELT.
It's called "Adaptive Optics". The primary mirror can change its shape to correct for atmospheric distortion as measured from the sodium (yellow) lasers.
That system (called adaptive optics does work, and is in use at almost all major telescopes worldwide for decades now. It all depends on massive computing power that can detect the 'flicker' of the light from lasers shining into the upper atmosphere and then correct the shape of the mirror by moving those (739?) hexagonal segments by microns at a time, in real time. The whole massive surface is constantly moving imperceptively to the human eye, to cancel out atmospheric disturbances. This is by far the largest application of the engineering, but it principal the system is well understood.
Do you know that the "Overwhelmingly Large Telescope" (OWL) was an actual design. It was abandoned in favor of the ELT because (wait for it), the budget was overwhelmingly large.

One thing is certain. If astronomers locate a planet with conditions favorable to life, huge corporations will vie for the opportunity to exploit and pollute it.
i wonder how advances in machine learning can play a role in laser correction effectiveness through the atmosphere. we could auto label with simulations on turbulence volumes. at runtime, we could use this to unwarp the image and know what parts are more accurately known in a given moment.
I'm not sure what exactly you mean - this is already exactly what happens with AO and laser guide stars. 1000 times per second the disturbance of the guide stars are measured and mirror correction is applied.
machine learning is only good for specific things (like crunching huge amounts of data). immediate fine tuning of optical data is really not its thing. it's not a 'cure all'.
At the beginning of the project, ESO project was the OWL telescope, a telescope with a 100 m primary mirror ! Perhaps the next step with the knowledge acquired with the ELT.

Light gathering and images capable of seeing weather patterns in the atmospheres of planets circling other sun's. I don't expect them to be easy to build or operate.

Of course the first telescopes in space was looking at humanity. The MOL, Manned Orbital Laboratories equipped with 71 in.mirror was amazing for the time. Trained at the same time as moon landings, dozens of astronauts spent decades in secret. 😊
that's called planning. it's fully funded and on schedule, so natural or man-made disasters notwithstanding, no reason it shouldn't be finished on time.
How can an Earth Bound telescope be any better then the JWST (James Webb Space Telescope)?? I'm sure it'll be great, but I'd rather we put something like this in space,,,, maybe the Darkside of the moon.
moon based telescope would be amazing, and there are plans of course. but webb has a specific function, so this observatory - like all others - will have its own. like most things, it's not one or the other, it's a combination which helps us further our knowledge.
This one has a diameter of 39m = 13*3. The JWST has a D = 6.5m = 13/2 and 2028 = 13*156, so 13 again, 3 times‼ What's going on⁉ Don't tell me that the Grand Opening will be on a Friday 13 ...
The "telescope construction site" is "high up" not "to be as close as possible to the stars". It is ridiculous to imply that where the telescope is being constructed, relative to if it were instead built at sea level, makes any difference as far as distance alone is concerned. Otherwise it would make more sense to place it at an accessible, convenient location. It is constructed at a high elevation to minimize the interference of atmospheric conditions. It is sloppy research, writing, and narration like this that calls into question the validity of the entire presentation and why I am bailing out at this point in the video to learn about this magnificent project elsewhere.
but it still wont answer the questions about whats floating around in our solar system., you know, is there a 9th planet etc. Dosnt matter how good the telescope, we cant answer these questions for some reason. These things are always supposed to see the end of the universe etc, but cant see whats under our nose.
that is not what is designed for. and 'we can't answer these questions' is highly disingenuous, typical argument used by science deniers, along with a lot of circular reasoning, appeals to incredulity etc.

I HOPE CHILLI AND THE EUROPEAN UNION FIND ASTROPARTICLE PHYSICS MARVELS!❤❤
It's a shame we can't get telescopes this size up above the atmosphere. A wonderful beast.
SpaceX will herald in the era of giant space telescopes and giant spacecraft in general.
the 'nautilus array' will have an effective area 80 times the JWST :)
Thank you Monty Python for naming it.
Of course the first telescopes in space was looking at humanity. The MOL, Manned Orbital Laboratories equipped with 71 in.mirror was amazing for the time. Trained at the same time as moon landings, dozens of astronauts spent decades in secret. 😊
9:12 Accuracy for mirror assembly: hundredths of micrometers, not hundreds. So, tens of nanometers.
Good video thanks👍
Creating landing zones!
Correction at 7:45: The JWST is not at the heart of the Milky Way.
תודה רבה על הסרטון! 🇮🇱
I look forward to hearing about new discoveries.
As early as 2028 = salesmanship language.
that's called planning. it's fully funded and on schedule, so natural or man-made disasters notwithstanding, no reason it shouldn't be finished on time.
How about some real close up shots of the moon and our local planets please?
How can an Earth Bound telescope be any better then the JWST (James Webb Space Telescope)??
I'm sure it'll be great, but I'd rather we put something like this in space,,,, maybe the Darkside of the moon.
moon based telescope would be amazing, and there are plans of course. but webb has a specific function, so this observatory - like all others - will have its own. like most things, it's not one or the other, it's a combination which helps us further our knowledge.
UNIVERSE is infinite in space and in time!
great video and i'm excited about the ELT! However, JWST isn't located at the heart of the Milky Way 🤔
This one has a diameter of 39m = 13*3. The JWST has a D = 6.5m = 13/2 and 2028 = 13*156, so 13 again, 3 times‼ What's going on⁉ Don't tell me that the Grand Opening will be on a Friday 13 ...
What would GALILEO GALILEI say, if he could see the ELT teleskop ,or the WRIGHT BROTHERS a AIRBUS 380 or BOEING 747 ?
Wonderful presentation. .but I don’t think the James Webb telescope is at the heart of the Milky Way, any more than we are.
I'm guessing the same telescope sitting on the Moon would rewrite most of what we know about the universes deepest mysteries.
The "telescope construction site" is "high up" not "to be as close as possible to the stars". It is ridiculous to imply that where the telescope is being constructed, relative to if it were instead built at sea level, makes any difference as far as distance alone is concerned. Otherwise it would make more sense to place it at an accessible, convenient location. It is constructed at a high elevation to minimize the interference of atmospheric conditions. It is sloppy research, writing, and narration like this that calls into question the validity of the entire presentation and why I am bailing out at this point in the video to learn about this magnificent project elsewhere.
How do they cool down those mirrors?!
they are designed and made to operate in the environment they will be in
Where is it????
Ai voice with ai transcript ..ergh.
Why where when
Until we develop technology like Star Trek, all we can do is look out at it.
My speculation there was beginning but no end😮
but it still wont answer the questions about whats floating around in our solar system., you know, is there a 9th planet etc.
Dosnt matter how good the telescope, we cant answer these questions for some reason.
These things are always supposed to see the end of the universe etc, but cant see whats under our nose.
that is not what is designed for. and 'we can't answer these questions' is highly disingenuous, typical argument used by science deniers, along with a lot of circular reasoning, appeals to incredulity etc.
Dang. Have to travel 130km x2 for lunch. Cool workplace at night. Hot as hades during the day. Siesta all day and work astrophysics at night. Damn cool.
How does it compare with JWST ?
It could be 100 times larger. We will never see the end.
