August - ESO’s Extremely Large Telescope

This image shows an artist’s rendering of the final design of ESO’s Extremely Large Telescope or ELT, due to start operating later this decade on Cerro Armazones in Chile’s Atacama Desert. With its revo-lutionary mirror of 39-metres in diameter it will be “the world’s biggest eye on the sky”, exploring the Universe in unprecedented depth and detail. The ELT will point lasers into the sky to measure turbu-lence in the atmosphere and correct astronomical images accordingly.
