A lonely antennae

ALMA is situated more than 5000 meters above sea level in the Chilean desert, on the Chajnantor plateau. Here, the dry air and thin atmosphere allow a spectacular view into the Universe and make it the perfect place for such a sensitive telescope. Just one (and another much further away) of the telescope's 66 antennas is pictured here, dwarfed by the stunning landscape for miles around. © M. Struik (CERN/ESO)
