ELT: The New Telescope that could Find the Origin of the Universe

In Chile's Atacama Desert, men and women are building the world's largest telescope. A titanic construction site with record numbers and stakes, isolated from the rest of the world. The Extremely Large Telescope, or ELT, is being built on the summit of Cerro Armazones, a 3,000-metre-high platform in northern Chile. With a primary mirror that will be the largest in the world when it goes into service, the ELT mega-telescope will be able to travel even further into the universe, offering us unprecedented images. A veritable revolution for astronomical researchers, and one we're eagerly awaiting... That's what we're going to see today in this new episode of Looking 4. Enjoy the video.

At 7:40, the narrator says about the JWST: "It's unique position at the heart of the Milky Way allows it to send back images that redefine our image of space". Wow, I guess we have warp drive now.

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.

Very proud to have played a minute part in this project

Contractors are amazing people to have built such a thing!

[Andre_XX]

There are a few iffy things in this video, some of which have already been mentioned by others. The telescope is not placed at the top of a mountain "to be as close as possible to the stars" 5:17. It is put there to get as far as possible out of the earth's atmosphere.

[evanherk]

It's not high up to be closer to the stars, but to get out of the atmosphere as much as possible.

[sanexpreso]

I am proud that the most powerful telescopes in the world are located in Chile

[chirilas]

👏Excellent documentary. Congratulations.👍

[greggy]

Highly impressed of this idea to search the galaxy.

[DCGreenZone]

I get "Contact" vibes from the construction photos. 😊

[syntaxed]

Crazy how the Atacama desert looks like Mars.

[RoyChartier]

The JWST orbits around Earth's L2. It is not located at the center of the galaxy.

[philochristos]

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.

It would be interesting to know what capability these land-based telescopes offer that can’t be provided by Webb and other space-based technology.

[goldwingerppg]

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.

My neighbors son in law is an engineer from here in australia who i over there working on it and he divides his time between there and ITER The tokomak fussion reactor. The last big job he worked on was the Burj Khalifa in the UAE

[oker]

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.

What's next? Ridiculously Large Telescope? Gigantuanly Large Telescope? Ludicously Large Telescope? The Sillyly Large Telescope?

[alpinecenter]

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.

[OperationHawaiiana]

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.
