Turn on your speakers and watch this time-lapse video full screen. Cerro Paranal is an astronomers paradise with its stunningly dark, steady, and transparent sky. Located in the barren Atacama Desert of Chile it is home to some of the world's leading telescopes. Operated by the European Southern Observatory (ESO ) the Very Large Telescope (VLT) is located on Paranal, composed of four 8 m telescopes which can combine their light to make a giant telescope by interferometry. Four smaller auxiliary telescopes, each 1.8 m in aperture, are essential elements of the VLT interferometer. The music by Carbon Based Lifeforms, song Arecibo extract from the album [Twentythree], write & produced by Johannes Hedberg and Daniel Segerstad, published by Ultimae.
