Activities

Observatory Sites:

I. Observatory at La Silla (Chile), operating several optical telescopes of up to 3.6 metres.

II. Cerro Paranal (Chile), where the world's largest optical telescope (interferometer) has been constructed to consist of four 8.2 metre and four 1.8 metre auxiliary telescopes; the four 8.2 metre telescopes and 2 of the auxiliary telescopes are already in regular operation. The technical development programme in European headquarters provides the observatory with advanced instruments. Over 1,500 proposals are made annually for use of ESO telescopes. OPC recommends which of these projects would appear to lead to the best science with the instrumentation available. It includes panels on different scientific domains:

 • Cosmology;

 • Galaxies and Galactic Nuclei;

 • ISM, Star Formation and Planetary Systems;

 • Stellar Evolution.

III. Leads the European participation in the Atacama Large Millimeter Array (ALMA) project (a North-American/European/East Asian collaboration), that operates 66 interconnected antennas at the Chajnantor site in Northern Chile at 5,000 m altitude; performs design studies for a future extremely large (up to 39.2-metre mirror diameter) ground-based optical telescope; conducts research projects and provides support to astronomers through fellowships and visiting professorships; organizes 3-5 symposia a year, conferences and workshops.
