Telescopes and star trails at Paranal Observatory, Atacama Desert, Chile

If you watch the stars here at Paranal Observatory, located in the Atacama Desert of northern Chile, you'll get one of the clearest views of the southern skies. This photo was taken with a very slow shutter speed – so what we're seeing is these stars' paths as they track across the night sky due to our planet's rotation.
