The European Southern Observatory initiates construction on the world's largest ground-based telescope structure.

This video details the design and scale of the Extremely Large Telescope, following the European Southern Observatory's award of the largest contract in ground-based astronomy history for the construction of the telescope's dome and primary structure.

The E-ELT represents a significant leap in ground-based astronomical capability. By securing the contract for the dome and telescope structure, the European Southern Observatory has moved into the implementation phase of this massive engineering project.

The project involves a vast array of international contributors, including the ACe Consortium, and technical expertise from organizations like CERN and various specialized instrument consortia. This update provides a comprehensive look at the design specifications that will define the future of observational astronomy.
