The Atacama Large Millimeter/submillimeter Array (ALMA) is an international partnership of the European Southern Observatory (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan, together with NRC (Canada), NSC and ASIAA (Taiwan), and KASI (Republic of Korea), in cooperation with the Republic of Chile. ALMA -the largest astronomical project in existence- is a single telescope of revolutionary design, composed of 66 high precision antennas located on the Chajnantor plateau, 5000 meters altitude in northern Chile.
Did you know that workers at high altitudes suffer reversible physiological, anatomical and biochemical changes resulting from descent under pressure? This is why ALMA staff attended a course on Chronic Intermittent Hypobaric Hypoxia. © D. Vidal - ALMA(ESO/NAOJ/NRAO)
Attendance was overwhelming at the 9th Great Night of Stars in the Santiago Metropolitan Park, where 1,400 people came out to stargaze and learn about astronomy, while observing the city by night from high above on San Cristóbal hill. © I. Lemus - ALMA(ESO/NAOJ/NRAO)
