New Website for ESO’s Extremely Large Telescope Launched

Published: 14 Jan 2021
Welcome to

ESO has launched a new website to deliver a wealth of information about the Extremely Large Telescope (ELT). Created for a wide range of audiences, the general public and astronomy experts alike can dive into the website to discover the new telescope, its instruments, some of the history behind this ambitious and challenging telescope, as well as how it will further our knowledge of the cosmos.

This is another exciting development in the history of the ELT, which is set to see first light later this decade. The new website provides the perfect way to stay up-to-date with future news relating to the telescope, and to learn more about the science, technology and the people who have contributed to its progress.
Each page of the website has been carefully arranged so that users encounter the most general information first: from reading the text at the top of each page, they can easily gain a broad understanding of the ELT, including overviews about its individual components, instruments and science cases. For more detailed or technical information, the user can scroll down, where the more specific details about the project are presented. 

The new site has a responsive design, meaning it functions smoothly across all devices: laptops, desktops, smartphones and tablets. It provides an informative and engaging user experience for all those interested in the telescope that will dramatically change what we know about our Universe.

Any newly launched website is likely to have undetected bugs or glitches and our new ELT website is no exception, despite extensive testing prior to the launch. If you spot any issues with the site, please report them to

ESO is grateful to the many individuals, within and outside the organisation, that made the ELT website possible.
