The world’s largest telescope is being built on top of a mountain in Chile to search for aliens in space. A very large dome is being built for this telescope. It will be operated by the European Southern Observatory (ESO). The name of this telescope is Extremely Large Telescope (ELT).
This telescope is being built on top of the Cerro Armazones mountain in the Atacama Desert of Chile.

This dome will protect the telescope from the heat and dust of the desert.
The primary mirror is 128 feet wide and weighs 200 tons
The primary mirror (M1) of ELT will be 128 feet wide. It will weigh around 200 tons. Big cranes and vehicles are installed inside the dome to set up the telescope. These pictures show how huge this telescope will be. 798 hexagonal glasses have been added to make the primary mirror.
