Mounted image 151: APEX on Chajnantor

The Atacama Pathfinder Experiment (APEX) telescope looks skyward during a bright, moonlit night on Chajnantor, one of the highest and driest observatory sites in the world. The beautiful sky is a testament to the excellent conditions offered by this site, which is also home to the ALMA observatory. On the left shine the stars in the tail of the constellation Scorpius (The Scorpion). In the centre, Sagittarius (The Archer) looms over APEX’s dish.
