Paranal from on High

This aerial photograph shows the summit of Cerro Paranal in northern Chile, the home of ESO’s Very Large Telescope (VLT). This flagship facility for ground-based astronomy hosts four 8.2-metre Unit Telescopes along with four mobile 1.8-metre Auxiliary Telescopes. These can work together, in groups of two or three, as one giant telescope, known as the VLT Interferometer, or VLTI.

This image displays the winding access road that leads up to the observing platform as well as the Observatory Control Room in the front. The picture helps give a sense of the remoteness of the VLT site, which is located in the extremely arid Atacama Desert at an altitude of 2600 metres. The first Unit Telescope began operations at Paranal in 1999. The VLT Survey Telescope, which is scheduled to begin observations in 2010, is missing from this photo, taken in 2004.
