Starstruck

The Swedish-ESO-Submillimetre Telescope (SEST) sits under the breathtaking sky at its home at the La Silla Observatory. Now decommissioned, SEST was the only sub-millimetre telescope in the southern hemisphere at the time of its first light, and is superseded by the Atacama Pathfinder Experiment (APEX) and the Atacama Large Millimeter/submillimeter Array (ALMA).
