ESO Celebrates its New Technology Telescope

6 février 1990

In the presence of a distinguished audience of ministers and high-ranking officials, as well as representatives of European industry and scientists from the member states, the European Southern Observatory today officially inaugurates its revolutionary 3.5-metre New Technology Telescope (NTT).

The festive act takes place simultaneously at ESO's Headquarters in Garching near Munich, F.R.Germany, and at the La Silla observatory in the Atacama desert, Chile. The two ESO sites, 12,000 kilometres apart, will be connected with a transatlantic TV link. During the ceremony, which commences at 14:15 MET (10:15 Chilean time), the NTT at La Silla will be remotely controlled from Europe via a satellite link.

Official speeches will be delivered by Dr. Antonio Ruberti, Minister of Research and Technology, Rome, Italy; Ambassador Jean-Pierre Keusch, Director of the Directorate of International Organizations, Bern, Switzerland; Dr. Heinz Riesenhuber, Federal Minister of Research and Technology, Bonn, Federal Republic of Germany; Professor Hubert Curien, Minister of Science and Technology, Paris, France. On behalf of ESO, interventions will be made by the Professor Per-Olof Lindblad, President of the ESO Council; Professor Harry van der Laan, ESO Director General; Professor Massimo Tarenghi, Manager of the NTT project; Dr. Raymond Wilson, ESO Senior Optical Scientist; Daniel Hofstadt, Chairman of the La Silla Management Team. The Bishop of La Serena, the capital of the IV Region in Chile, in which La Silla is located, will pronounce a blessing of the new instrument.

At the inaugural ceremony, a 25-minute BBC-made film about ESO will be shown for the first time. The most recent astronomical images from the NTT will also be presented.

The inauguration will be followed by a scientific session with talks by three distinguished European astrophysicists, Professors G. Miley (Leiden, The Netherlands), F. Pacini (Florence, Italy) and G. Tammann (Basel, Switzerland).

The ESO NTT is a telescope of the 21st century and incorporates many new technologies, in particular within optics, mechanics and electronics. Moreover, the NTT building has been especially conceived to ensure a minimal influence on the observations.

Already during the night of "first light" (eso8903), the NTT has demonstrated its enormous observational possibilities. This has been fully confirmed by a great variety of astronomical observations, carried out by ESO staff astronomers in the course of the start-up phase. Unprecedentedly sharp images have been obtained (down to 0.33 arcseconds FWHM) and extremely faint objects have been recorded (under seeing conditions not unusual at La Silla, stars fainter than 25th magnitude are registered in 10-minute CCD exposures).

The first visiting astronomers from ESO member countries to the NTT were received at La Silla on January 17, 1990. The first programme was dedicated to Supernova 1987A in the Large Magellanic Cloud.

The NTT, while an excellent telescope in its own right, is also the forerunner of ESO's next telescope project, the 16-metre Very Large Telescope, which is expected to be ready in 1999. Consisting of four 8.2-metre telescopes, it will become the largest ground-based telescope in the world.
