ELT trailer 2020 | ELT Updates

The Extremely Large Telescope (ELT), currently under construction in Chile, will be the world's biggest eye on the sky when it sees first light, planned for 2025. This revolutionary ground-based ESO telescope is set to be the largest of its kind in the world. 798 individual hexagonal segments will make up the telescope's main mirror, which spans 39 metres in diameter. The unique 5-mirror design of this telescope and advanced imaging technology will allow the ELT to produce images 15 times sharper than the Hubble Space Telescope. The ELT’s light-gathering power will allow astronomers worldwide to delve deeper and more clearly into our Universe, addressing the most prominent astrophysics questions of our time.
The design for the ELT shown here is preliminary.

The best thing about this project is that we don't have to fear a rapid unplanned disassembly.

[@jelliott8424]

Given all the JWST setbacks it almost feels like destiny

[@glutinousmaximus]

Wow - the most powerful single telescope! What a fantastic tool it promises to be! Thanks for posting.

[@cal8338]

Imagine some bird shitting on it, and the scientist said they found new galaxy

[@LilyoftheValeyrising]

Probably the best thing to come out of 2020.

[@user-ec7rm1tp3t]

Awesome

[@hisroyalairness23MJ]

I wish this marvel of engineering will don't need more time than 2025 to be operational. Is a game changer.

[@Albatard1981]

Wiki : 2027 😢

[@TusharDeb]

Let's go!

[@EricMalette]

The telescope Earth deserves.

[@abhroy]

Hearty Thanks to Herbert Zodet & MoveTwo -- for this superb creation .

[@lucianolizana446]

This is just incredible!

[@randy6999]

Awesome!!

[@user-eb8dd3zr1v]

Looking forward!

[@user-qv7vn6mp8i]

Awesome!

[@rootz420]

How far along in development is it? It's been like 10+ years already

[@mariadaluzmoutinho5701]

Os olhos são os espelhos que reflectem a beleza do Universo e põem a nu admiráveis enigmas aos cientistas!!! Que grande máquina na sua concepção em todas as vertentes!! Por estes olhos podemos ver outras dimensões que nós simplesmente não podemos valcançar!! São estas ideias que evoluímos e podíamos nos regenerar como faz o Sol e outras estrelas não é??

[@gac200076]

Good luck!

[@claudebigras43]

Wow infiniment petit a infiniment grand , microscope a téléscope , nous sommes les fourmis de l'univers

[@Container-11]

Ich würde den Bau dieses Teleskopes gerne verfolgen.... Ende 2018- ein Foto zu Bginn der Fundamentarbeiten. Ende 2019- ein Foto der Fundamentarbeiten und ein kleines Video. Bald ist 2020 vorbei .... und nix, Null, nada, niente nulla .... Wieso bekommt es die ESA nicht hin eimal im Monat ein Foto von der Baustelle zu "schiessen" ? Es gibt eine Webcam am Fuße des Berges, sehr witzig :-) Das grösste, tollste Teleskop der Welt wird gebaut und Niemand kann teilhaben ....Niemand kann dabei zuschauen wie es entsteht !!! Vielen Dank dafür. Bis zur Fertigstellung 2025 oder wann auch immer sehe ich also noch 5 Fotos von dort.

[@jesusvieira7180]

Yesssssss

[@rhoddryice5412]

Imagine a beast like this built on the Moon. Or would dust ruin the mirrors?

[@glutinousmaximus]

We could build or navigate such a telescope there. Dust would not really be a problem, I don't think, since there is no air there to scatter dust about. But space would be a great location - except we are already working on the James Webb telescope!

[@dominic5386]

Adam Mangler oh, I misread the comment, I though it said “pointed at the moon”, not built there. Silly me

[@WetaMantis]

You'll need to land your rockets far from it then. micro-meteorites could be an issue.

[@alien105cz]

Great project. I worry how starlink make trailes ok photos on every oure and these telescopes

[@Ben_Stewart]

Amazing times. Now how will #starlink affect this?

[@Albatard1981]

Same fear for me... #stopstarlink . I love science & astronomy, not polluting space business.

faut des filtre positronique , pour savoir si c est un bigbang par galaxie

[@romainmarchal7956]

qu es qui fait l interaction du temps +1seconde qui fait naitre une galaxie

[@romainmarchal7956]

le temps est sur la rotation de la planete , la multi couleur galactique c est temps relatif x+1s ou tempsrelatif (x-1s)/centre galactique, positron ou electron

[@Michael_Michaels]

This is awesome but I want to understand how do they manage to filter the atmosphere.

[@abhroy]

Watch this episode -- ESOcast 84 . Your query answered & explained there :)

[@Michael_Michaels]

@@abhroy thank you.

[@rhoddryice5412]

@@abhroy Which video? Do you've got a link, please.

[@abhroy]

@ Rhoddry . I will avoid submitting a URL here . But yes , you may wish to search for this exact title here in KZbin -- -- "ESOcast 84: The New E-ELT Design Unveiled Jun 3, 2016" . Hope this helps :)

[@Pharisaeus]

tl;dr: adaptive optics. Those yellow lasers light sodium atoms very high up and create an artificial "guide stars". Such "stars" have known characteristics and by comparing what you can see via the telescope with what it should look like, you can calculate the "distortion" and apply measures to negate it, effectively removing the atmospheric effects.

[@msc8275]

why 39 meter , go big and make it 100

[@abhroy]

Your question is answered & explained in this post -- -- Launch Pad Astronomy world's biggest optical telescope ELT . Hope this helps :)

[@speedybasket5205]

It would take like 20 years

[@danipay]

So is it better than james webb?

[@slar844]

Actually, no it's not.

[@adrien5834]

@@slar844 It's a different tool. It has advantages and disadvantages vs JWST. Its main disadvantage is Musk's shitty Starlink satellite constellation...

[@marcostj01]

Elon Musk: I'm gonna end this telescope's whole career

[@swedensy]

Stop the lies. ESO TV said it will be finished on 2019.

[@PepePateaPotos]

Por qué "european" si estará construido en uno de los lugares más iconicos y hermosos de Sudamérica? Cero respeto los europeos con los sudamericanos como siempre.

[@brandaanvandebotermet4579]

Because it is payed for and developed by ESA which is in fact a European space agency ?

[@solrac5149]

Porque el dinero lo hemos pagado entre todos los países de la Unión Europea, por qué te molesta que el mayor telescopio del mundo se esté construyendo en tu país? Eres tonto?

[@johnstrawb3521]

Why the repulsive music and lack of specifics? Awful presentation---very amateurish.
