April – Sunset over La Silla

ESO’s La Silla Observatory looks down over the stunning sunset in Chile’s Atacama Desert. At 2400 metres above sea level and far from the light pollution of human civilisation, the site is host to one of the most spectacular dark skies in the world, and thus provides the perfect view for ESO’s telescopes. Fog hovers over the valleys surrounding La Silla, while the setting Sun lights up the horizon in orange. Once the Sun disappears, the night sky will reveal impressive astronomical sights, just waiting to be observed.
