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.
Some extra info: Often the adaptive optics uses actual stars close to the observation area to detect atmospheric distortions and corrects for these distortions in real time. If during an observation there are no guide stars near the observation area these yellow lasers create artificial guide stars by exciting the thin sodium layer around earth at a height around 95 km. The excited sodium produces light points in the direction of observation which can provide the information needed to counteract the atmospheric distortion by the adaptic optics system.
Actually, the laser guide stars are used only when there are no suitable stars in the focal plane. The amount of stray light coming from the laser beams is quite high. In fact, it's so high it affects the telescopes in the neighborhood. In the case of the ELT's laser guide star system, when turned on, it will effectively block part of the sky for the VLT which will be forced to reshuffle scheduled observing blocks. That's also one of the reasons why ELT will not have its own control room, but it will be operated from the VLT's control room.

This is so amazing, excitement is an understatement. I've been patiently waiting for news ! Its really coming along nicely ! Green Bank observatory is in my state, I wish I could go see it ❤🙏 one day I WILL! This is wondeful news ! Thank you !
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.
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... ruclips.net/video/QqRREz0iBes/видео.htmlsi=ZdiKIncFMCtychfz

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.

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.
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.
It seemed like this video was throwing shade at JWST, which felt odd. JWST can see the earliest light and stars forming in dust clouds that no land base or other telescopes can do. There’s no doubt ELT will be great instrument for scientists to use and they will be able to do maintenance and upgrades, but the video seemed a little insecure. The Atacama Large Millimeter Array (ALMA) is an amazing instrument too, especially when all of the telescopes come online.
JWST is an Infrared radio telescope and, just like visible light, can NOT see through the ZOA of this Milky Way and therefore that part of the sky can NOT be viewed through this radio telescope, this completely unlike X-ray radio telescopes!!
Like it or not JWST cost a small fortune compared to this instrument and it does NOT have the resolve power as well. Now that atmospheric correction has come to the forefront ground based instruments are still a LOT cheaper AND they're repairable... two huge pluses over space based instruments residing at Lagrange points. Unfortunately placing ANYTHING ANYWHERE in space is extremely pricey.
@@leecowell8165 We basically said the same things. JWST cost was more than a small fortune and took many years and man hours to build and deploy, however, I believe it was worth it. It can gather information no other telescope can and the technology developed to build it will help future missions to deploy scientific instruments that will help advance man’s knowledge of the universe. The more advanced telescopes built, the more tools scientists will have to study the universe, which is a very good thing in my opinion.
You are wrong. Our universe has beginning and an end. There must have creator for our universe. Like us, human, Allah creates us. Same like to our universe. Nothing can happen without a creator.
if this is so, then the protest against TMT can finally come to an end for TMT would no longer be needed. native hawaiian elders can finally lay at peace knowing that they succeeded protecting Mauna kea and protecting what is left on that mountain.
Your Videos are GREAT. They image quality is spotless, the voice over is great, the topics are inspiring and the integration of 3d animations and real footage seems unsusally organic. They are, however, a tad too long. I rarely watch over 6 minutes. Not because of the length itself, but because they seem a bit repetitive. Or often promise a theme that is addressed at a later point while delivering a lot of other topics in between. I feel if u break them down in shorter videos you will have as looking at more of them :-)
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'.
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.
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.
7:44 - "Its unique position at the heart of the Milky Way enables it to send back images" Uh, no... the JWST *IS NOT* in the center of our galaxy, geniuses.
Mother Nature truly is a cruel mistress… she creates beautiful masterpieces of terra forma (Atacama desert) and yet within that beauty, lies deadly traps 😕🤔
The bigger they make it, the further they see, Does it go on for eternity? Let's decree: In the heart of the cosmos, where time and space blend, Our quest for knowledge may never end. Through nebulae, galaxies, and the cosmic sea, The ELT gazes, as far as could be. Does it go on for eternity? We yearn to know, In the dance of the cosmos, in its eternal flow. The bigger they make it, the deeper we peer, Into the cosmic frontier, with hope and fear. Does it go on for eternity? The stars hold the key, In the silent symphony of the cosmic spree. So, here's to the ELT, our sentinel of the night, The bigger they make it, the closer we're to the light. Does it go on for eternity? Time will decree, In the grand cosmic theatre, the final spree.
@@Justwantahover At some time in the future I foresee telescopes built in space on the order of a kilometer or more. 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. The imaging and focusing will be challenging. I would also expect them to very slow to change from one target star to another.

At 5:19 the narrator says...'' to be close as possible to the stars, the telescope construction site is also high up ".......that is so wrong....what difference can a few hundred meters can make, when stellar distances are messure in light years.....
Surely, turbulence in the atmosphere, which scatters light from stars and causes the image to appear blurred, twinkling, or distorted, will affect image clarity, unless one resorts to AI and other computer tech? If that were to be the case, there still isn't a true image?
The amazing discoveries that the JWT has made in just the last six months must almost make these land based telescopes a thing of the past , But on the other hand ,,,,there are five fingers
In centuries to come when we can combine the properties of light photons we'll be able to put small telescopes millions of miles apart and effectively use this phenomena to have 1 telescope with a miltimillion mile diameter. This is the last generation of single monolithic telescopes.

7:44 - "Its unique position at the heart of the Milky Way enables it to send back images"
Uh, no... the JWST *IS NOT* in the center of our galaxy, geniuses.
Very educational
Similarities with the landscapes of far away stars ???
Must be very unusual and very low gravity and very cold stars.
Very good news ❤ we are waiting for new information from space ❤
Amazing and wonderful technology
Mother Nature truly is a cruel mistress… she creates beautiful masterpieces of terra forma (Atacama desert) and yet within that beauty, lies deadly traps 😕🤔
תודה רבה על הסרטון! 🇮🇱
The bigger they make it, the further they see,
Does it go on for eternity? Let's decree:
In the heart of the cosmos, where time and space blend,
Our quest for knowledge may never end.
Through nebulae, galaxies, and the cosmic sea,
The ELT gazes, as far as could be.
Does it go on for eternity? We yearn to know,
In the dance of the cosmos, in its eternal flow.
The bigger they make it, the deeper we peer,
Into the cosmic frontier, with hope and fear.
Does it go on for eternity? The stars hold the key,
In the silent symphony of the cosmic spree.
So, here's to the ELT, our sentinel of the night,
The bigger they make it, the closer we're to the light.
Does it go on for eternity? Time will decree,
In the grand cosmic theatre, the final spree.
They should have named it "The Really Big Big Big Telescope".
Biggus Dickus Telescopus :D
Magnificent constructions but the terrible names are the stuff of legends. Remember the planned and cancelled OWL? Overwhelmingly Large Telescope.
Nah, they should have named the Acme Telescope and used Willy Coyote peering through a telescope as the logo. 😉
They were planning to build a 100 meter telescope. I think it was going to be called the Overwhelmingly Large telescope. 😅

At some time in the future I foresee telescopes built in space on the order of a kilometer or more. 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. The imaging and focusing will be challenging. I would also expect them to very slow to change from one target star to another.
Bacon littice and tomato used to be my favorite sandwich. But I did like turkey club sandwiches. They would melt in your mouth. 😊
You may want to tell your readers that littice comes from the moon io and is roughly equivalent to lettuce here on earth, littice is a bit sweet for me. However, each to his own.

What boggles my mind is how they manage to focus multiple mirrors so precisely
What boggles my mind is the fact that spiders fart 😂😂😂

Grow up. !!!
@@claudelebel49oh dear what a silly little man you are - someone needs to learn how to be less critical, more accepting, accept that people are all different and see humour in different ways and places and also learn some bloody manners 😂
Hi thank you very much, great show.
Gaze far enough into the universe, and you'll see yourself looking at you.
'To be as close as possible to the stars, the telescope is also high up.' - I think someone is having a laugh.
We don’t need a telescope to find the origins of the universe, we need a microscope
Excellent explanation! Would that such cooperation be the complete norm for all nations.. We need to be one!
Quite comprehensive presentation
i wonder f steel braces can distort signal on the mirror disc?
🇨🇱🔭
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 :)
I'll go live in Atacama...
Looking for a physical point as the origin of the universe is pointless, because it no longer exists in our spatial dimensions.
Right on, but boneheads need a job too lol
I have news for you: there never was a point where the universe originated. It has always been here.
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. 😊
Creating landing zones!
We're so opssesed about the origin of the universe that we don't know where we're headed.
Those guys who found the origin of the universe need a really long break. And some professional help, too.
How do they cool down those mirrors?!
they are designed and made to operate in the environment they will be in
The earth is midway between the edge of the milky way and the centre. In the Orion Cygnus arm
The site is unaffected from visual pollution
Elon Musk : hold my diet coke
So when they say 2028, they really mean the early to mid 2040's!
Yes but much better later than never.
Yep , Putting the JWST into space was like at least a twelve year overrun . 😒
@@icosthop9998 well they are sending a bigger better one to follow JWST, does visible light too!!
Bout time.
At 5:19 the narrator says...'' to be close as possible to the stars, the telescope construction site is also high up ".......that is so wrong....what difference can a few hundred meters can make, when stellar distances are messure in light years.....
Surely, turbulence in the atmosphere, which scatters light from stars and causes the image to appear blurred, twinkling, or distorted, will affect image clarity, unless one resorts to AI and other computer tech? If that were to be the case, there still isn't a true image?
The amazing discoveries that the JWT has made in just the last six months must almost make these land based telescopes a thing of the past , But on the other hand ,,,,there are five fingers
I'm guessing the same telescope sitting on the Moon would rewrite most of what we know about the universes deepest mysteries.
Imagine telescopes in 2100, I wish I could see those images.
Catchy name.
Let’s get some RADIO telescopes in the L2 range…for some clear “signals”
In centuries to come when we can combine the properties of light photons we'll be able to put small telescopes millions of miles apart and effectively use this phenomena to have 1 telescope with a miltimillion mile diameter. This is the last generation of single monolithic telescopes.
I look forward to hearing about new discoveries.
HILARIOUS WE ALREADY HAVE ONE ITS JAMES WEBB😢😢😢
ELT will not discover all the secrets of the Universe. For that you need a 42 m telescope!
There is nothing to be discovered, everything that can be discovered has already been discovered.
How does it compare with JWST ?
After the ELT they will build the HLT. The Humungously large telescope.
although i would rather it were called the ULT or Unfeasibly Large Telescope
I HOPE CHILLI AND THE EUROPEAN UNION FIND ASTROPARTICLE PHYSICS MARVELS!❤❤
What exactly do "scientists in a frenzy" look like? Is their hair on fire? LOL!
Sounds like AI generated, the text also seems to be AI generated.
It is.
#BloodCorvinus #Renessme-Andromeda #Bella-Edward(Cullen) #Twilight-SpiralGalaxy!
UNIVERSE is infinite in space and in time!
I like it
Elt and magellan will reveal good things for the universe
great video and i'm excited about the ELT! However, JWST isn't located at the heart of the Milky Way 🤔
