Stars of prominent constellations Orion, Canis Major, and Taurus are photographed over the Cerro Paranal Observatory in the barren Atacama Desert. The Large and Small Magellanic Clouds are on the right towards the south and both red and green airglow (natural emission of the Earth upper atmosphere) appear near the horizon. With its dark, steady, and transparent sky, Paranal 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-meter telescopes and smaller auxiliary telescopes, each 1.8 m in aperture, which are important elements of the VLT interferometer.
