Around the ALMA OSF

View of part of the ALMA base camp, near the Operations Support Facility (OSF), located at 2900 m altitude on the road to the Chajnantor plateau. Chajnantor is the home of the Atacama Large Millimeter/submillimeter Array (ALMA), the largest astronomical project in existence and the largest radio telescope in the world. On the background, the unmistakable conic shape of the 5920m high Licancabur volcano.
