ESO's Extremely Large Telescope may not have an original name, but it's accurate! Its 39 m main mirror will weigh about 200 tonnes, and what you see here is the huge cell that will hold it.
The mirror will comprise 798 hexagonal segments working together as a single mirror. All segment blanks have been cast and are now being polished, after which they'll be shipped to #Chile where they'll be coated with silver.

The image shows a partially-constructed white hexagonal lattice structure with a honeycomb-like design, in the interior of a metallic dome structure with some blue cladding on the exterior. In the centre of the lattice structure, there is a hexagonal hole in the structure.
