European Southern Observatory
The European Southern Observatory operates the La Silla and Paranal (Fig. 7.1)
observatories in Chile. La Silla is 160 km from La Serena at an altitude of 2400 m;
Paranal, 120 km from Antofagasta at an altitude of 2635 m. The Very Large
Telescope (VLT) on Cerro Paranal is actually four individual telescopes, each with
apertures of 8.2-m diameters. Both laser and natural guide star adaptive optics sys-
tems, known as the multiapplication curvature adaptive optics (MACAO, Fig. 7.2), a
60-element curvature adaptive optics system, have been developed for the observa-
tory. La Silla is home to the 3.6-m New Technology Telescope (NTT), a 3.6-m, and
a 2.2-m telescope, all equipped with imaging and spectrographic instruments.
