The Cerro Armazones mountain in the Chilean desert, near ESO's Paranal Observatory, will be the site for the European Extremely Large Telescope (ELT), which, with its 39-metre diameter mirror, will be the world’s biggest eye on the sky. Here, an artist's rendering shows how the telescope will look on the mountain when it is complete. Credit: ESO/L. Calçada |
