This telescope should be talked about as much as the JWST. It will revolutionize astronomy!

It certainly will. However, it won't be until at least 2028, which gives 5 years to the JWST to do its magic (considering its life span was supposed to be from 5 to 10 years and hopefully it'll last longer), the ELT will be a fine successor!

Dear ESO: please bring back the ESO voice-over lady. She brings gravitas to everything.

Com toda a certeza, não vai ser só o maior, mas também, o mais revolucionário, desde a sua invenção, a quase 500 anos atrás.

Can't wait to see what it can do, great stuff!

Beautiful!

Very nice, please build faster

Incrível ❤ Espero que fique pronto logo🤩👍🏽✨

Bravo ❤❤

I'm so stoked my dudes

Really amazing ❤

Magnífico 👍

Incredible

Realy I like this video

Fantástico

Incrivel obra...diria cósmica!!

wow

the largest cranes in the world are small as ants next to it.. it's impressive

What's bigger than "extremely" ?

In principle, something “overwhelmingly large”. :) Before developing the ELT concept, ESO engaged in the concept study for an Overwhelmingly Large Telescope (OWL) with a 100-m mirror (for comparison, the ELT primary mirror will be 39m in diameter). The OWL proved to be too complex, but it did pave the way for the ELT. You can read about it here: www.eso.org/sci/facilities/eelt/owl/index.html

Once it is built and is functioning with no glitches, given the right observation conditions i.e. perfect conditions, would it be able to photograph a nearby exo-planet?

Yes, and direct imaging of exoplanets is one of the main science cases for the ELT. Images of exoplanets have already been captured by current facilities, with the very first one having been taken with ESO’s VLT almost two decades ago. However, very few direct observations of planets have been made to date. Currently, most exoplanets are detected by the radial velocity method or the transit technique, which however are indirect and very limited in the information they can provide about the planet itself. Thanks to its very large collecting power, the ELT will dramatically increase our ability to directly image, and hence understand, exoplanets.

@@ESOobservatory Good. I look forward to the first photograph of an exoplanet like we can photograph the distant planets in our system. It'd be nice bonus if we also found out it has advanced technological life. Just think if they have also built an ELT, and are looking at our system, and they get a photograph of Earth.

Will it be possible to observe human traces on the moon and the equipment left there with this telescope?

The answer is no. This has to do with the resolution (in other words, the size of the smallest details that can be distinguished at a given distance) of the 39-metre ELT. Using the ELT’s built-in adaptive optics and observing at visible wavelengths, the resolution will correspond to about 10 metres on the surface of the Moon. However, the parts of, for example, the lunar modules that are left on the Moon are less than 10 metres in size. So, the ELT is not big enough to show the shape of the lander, even if it could be imaged, and it would be indistinguishable from a rock. A perfect telescope of about 200 metres in diameter would be needed to show the landers as anything more than an unresolved blob and resolve their shapes.

"the dome a footprint roughly equivalent to that of a football pitch" It pleases me that you adhere to the correct IS measurement units.
