World’s largest telescope dome takes shape | ELT updates

The dome of ESO’s Extremely Large Telescope (ELT) begins to take shape. This is the largest telescope dome ever build. The structure is about 88 metres in diameter and nearly 80 metres high, giving the dome a footprint roughly equivalent to that of a football pitch. The giant ELT dome will house the telescope and its interior structure, providing protection from the extreme environment of Chile’s Atacama Desert.
