Shouldn't it read: "The ELT will be the largest telescope" instead of "will be the largest ELT" ? — Preceding unsigned comment added by 93.231.140.194 (talk) 10:43, 3 September 2024 (UTC)Reply

Comparisons

edit

The article currently compares the ELT's light gathering area and sharpness to the Hubble. Now that the James Webb Space Telescope is in service, it might be better to compare to the Webb. The ELT has 38x the light gathering area of the Webb (straightforward calculation 978/25.4), and about 20x the resolution (0.1 / 0.005 -- see [1]). Unless there is some objection, I will update the article. --Macrakis (talk) 12:03, 8 November 2023 (UTC)Reply

The Extremely Large Telescope (ELT) is an astronomical observatory under construction. Part of the European Southern Observatory (ESO) agency, it is located on top of Cerro Armazones in the Atacama Desert of northern Chile. The project was proposed in 2011 with construction beginning in 2017. Completion and first light is anticipated to take place in 2028. The ELT's design consists of a reflecting telescope with a 39.3-metre-diameter (130-foot) segmented primary mirror and a 4.2 m (14 ft) diameter secondary mirror. When completed, it will be the world's largest optical telescope. This picture shows a schematic view of the ELT, released by the ESO in 2012.
