The Great Carina Nebula is photographed above the Cerro Paranal Observatory in the Atacama Desert, Chile. Left of the nebula is the IC 2602, also known as the Theta Carinae Cluster or Southern Pleiades, an open cluster in the constellation Carina with many young blue stars. At 2,635 metres (8,645 ft) from sea level, with its dark and transparent sky, Paranal is home to the Very Large Telescope (VLT), operated by the European Southern Observatory (ESO). It is composed of four 8-metre telescopes.
