Rise of a Giant: The Extremely Large Telescope
With a primary mirror of diameter 39m (about 20% larger than Stone Henge's Sarsen Circle), the European Southern Observatory's (ESO) Extremely Large Telescope (ELT) will be the "World's Biggest Eye on the Sky" operating in the visible to infrared (IR) wavelength range. The ELT will collect 13 times more light than the largest visible/IR telescopes today allowing us to peer deeper and further in the Universe than ever before. Using novel technologies (including adaptive optics) to overcome the effect of the atmosphere, the ELT will be able to take images of the sky in exquisite detail, 16 times sharper than the Hubble Space Telescope. This deeper and finer view of the Universe will help to address many exciting open questions in contemporary astrophysics and cosmology, including the nature of extra-solar planets and the first galaxies to form stars at the edge of the visible Universe. More excitingly, it will make many discoveries, raising new questions. In this talk, I will describe the major steps in telescope design that have led up to the forthcoming era of extremely large telescopes and some of the scientific questions they will address. The next decade will witness exciting new discoveries in the Universe with facilities like the ELTs, the James Webb Space Telescope, the Vera C. Rubin Observatory, and the Square Kilometre Array (to name but a few) becoming operational. In this landscape, the ELT will play a central role in delivering ground-breaking science contributing to our evolving understanding of the Universe.
World's Biggest Optical Telescope - ELT
The World's Biggest Optical Telescope, the Extremely Large Telescope is a 39.3 meter behemoth.
But will Starlink ruin it? https://www.youtube.com/watch?v=soTqc1Y_qU8&list=PLrAnGxL8nxOHR01diTRdgqhUto6Jqxgx9&index=1
When completed in 2024, it will be the largest optical and infrared telescope in the world. #telescopes #elt #extremelylargetelescope 🔴 Subscribe to my channel: https://youtube.com/christianready?sub_confirmation=1 🔴 Share this video with a friend: https://youtu.be/fvjhldjESGo 🔴 From out of town?

Casting a $20 Million Mirror for the World’s Largest Telescope
Building a mirror for any giant telescope is no simple feat. The sheer size of the glass, the nanometer precision of its curves, its carefully calculated optics, and the adaptive software required to run it make this a task of herculean proportions. But the recent castings of the 15-metric ton, off-axis mirrors for the Giant Magellan Telescope forced engineers to push the design and manufacturing process beyond all previous limits.

Extremely Large Telescope Model Tested in Wind Tunnel
The high winds of Cerro Armazones in Chile, future home the European Southern Observatory’s Extremely Large Telescope, have to be accounted for when building a structure with a 80 meter (262 ft.) high dome. A scale model of the telescope is undergoing testing in a wind tunnel to assess. Credit: ESO
Ekstremalnie Wielki Teleskop - Astronarium odc. 42
Teleskop tak wielki, jak żaden wcześniej. Gigantyczny instrument, który ma przesunąć granice naszego poznania Wszechświata. Oto Ekstremalnie Wielki Teleskop (ELT). To niemal 40-metrowy kolos, którego budowa rozpoczęła się na pustyni Atakama. Co takiego ma nam pokazać i jaką rolę w jego powstaniu odegra Polska? W tym programie przyjrzymy się bliżej tej gigantycznej konstrukcji budowanej przez Europejskie Obserwatorium Południowe (ESO). Zapraszamy na Astronarium! Odcinek 42 - Ekstremalnie Wielki Teleskop

New European Extremely Large Telescope Design Unveild
Extremely Large Telescopes are considered worldwide as one of the highest priorities in ground-based astronomy. They will vastly advance astrophysical knowledge, allowing detailed studies of subjects including planets around other stars, the first objects in the Universe, super-massive black holes, and the nature and distribution of the dark matter and dark energy which dominate the Universe.

Europe's largest telescope is in Chile
The European Southern Observatory is building an enormous new telescope high in the Atacama Desert in Chile. Even though the location is on the other side of the planet from Europe, the location offers some of the best views of space on Earth. When finished, this new telescope will allow astronomers to gaze at Earth-sized planets in far off solar systems and aid the search for life beyond our world. Produced by Matt Stuart and Sean Kane.

E-ELT: Europe's Extreme New Telescope - Space
The Atacama desert in Chile is famous for nothing: no water, no plants, no animals. That makes it a perfect place for astronomy, and the ideal location to build the European Extremely Large Telescope, or E-ELT, the world's largest ever optical and infrared telescope. The first stage of construction is destruction, namely blowing up the top of a mountain.
