APEX

Welcome to the APEX web site. You will find here all about our project and the amazing 12-m radio telescope that we operate in northern Chile. APEX is located in a privileged location, on the "Llano de Chajnantor", at 5100 m. above the sea level. At such high altitude, the dry atmosphere of the Atacama desert opens up a unique window to observe the millimetre and sub-millimetre light.

Primary location: San Pedro De Atacama Chile
