Observatoire Alma - Crédit ESONAOJNRAO W Garnier

Aerial view of the ALMA Operations Support Facility (OSF), located at 2900 metres altitude, on the road to Chajnantor — partially visible near the top-right edge of the picture. On the right, the partners’ antenna integration sites are seen — from the bottom to the top are the North American, the Japanese and the European sites. At the centre of the picture is the main OSF building, while on the left the workers’ camps are visible.
