Construction of the first phase of the telescope has commenced which will lead to the construction of the fully working European Extremely Large Telescope, which is scheduled to be completed in 2026.
Is the European Extremely Large Telescope finished?
An artist's impression of the European Extremely Large Telescope (E-ELT) atop Cerro Armazones in Chile's Atacama Desert. With a primary mirror 129 feet (39.3 m) across, it will be the world's largest optical-infrared telescope when completed about 2022.
What is the largest telescope that is currently built?
When completed, it is planned to be the world's largest optical/near-infrared extremely large telescope….Extremely Large Telescope.

How large will the extremely large telescope be?
39-metre The Extremely Large Telescope (ELT) will have a 39-metre mirror (almost half the length of a football pitch) and will thus be by far the biggest telescope in the world to observe in the visible and the near-infrared (there are larger radio telescopes).
Why was the Overwhelmingly Large telescope Cancelled?
(Other telescopes, like the Giant Magellan Telescope (GMT) will be in operation before all of the mirrors are installed.) In the end, OWL's cost became too great, and the project was cancelled.
What will the ELT see?
The ELT should be able to discover worlds down to Earth-like masses, as well as directly image larger planets and potentially characterize their atmospheres. It will observe giant planets around young stars and in star-forming regions, tracing their evolution over time.
How big is the James Webb telescope?
Hubble is 13.2 metres (43.5 ft.) long and its maximum diameter is 4.2 metres (14 ft.) It is about the size of a large truck.
How Long Will Webb telescope last?
In simple words, less fuel than originally planned for is needed to correct Webb's trajectory toward its final orbit around the L2 (second Lagrange point). As a result, Webb has a reserve of fuel to keep it operational for 10 years or more.
What is the next big telescope?
NASA's James Webb Space Telescope, the agency's successor to the famous Hubble telescope, launched on Dec. 25, 2021 on a mission to study the earliest stars and peer back farther into the universe's past than ever before.
What is the largest ground based telescope?
Gran Telescopio Canarias Gran Telescopio Canarias (GTC) A 34-foot (10.4-meter) telescope located on La Palma of Spain's Canary Islands seized the top spot as the world's biggest ground-based optical telescope in 2009. A main mirror that consists of 36 hexagonal segments contains some of the smoothest surfaces ever made.
