 Judgment 1854 (ILOAT) - Administrative Tribunal
Some years ago, the ESO commenced a project to establish a Very Large Telescope (VLT) at the Paranal observatory, which is on a mountain at a distance of 130 km from the town of Antofagasta, about 1,200 kms north of Santiago.
During that period, since the construction phase of the Paranal VLT was coming to an end and the VLT was expected to begin to operate in early 1998, the ESO was considering the reorganisation of the administrative structure required for the operative phase of the VLT.
The complainant contends that the functions which he had been performing continued to be required even after the new Paranal observatory became operational, and that in fact the duties of the new post of "Paranal Administrator" were substantially the same as those of his former post.

This photo (in near-infrared light at wavelength 2.3 µm) was obtained in the morning of April 30, 2002, with the NAOS-CONICA (NACO) adaptive optics (AO) camera mounted on the ESO VLT 8.2-m YEPUN telescope at the Paranal Observatory.
It was made with the NAOS-CONICA (NACO) adaptive optics camera mounted on the ESO VLT 8.2-m YEPUN telescope at the Paranal Observatory.
Although the atmosphere above Paranal was rather turbulent that morning - the nominal seeing was measured as 1.5 arcsec - and despite the use of an extended feature for the guiding, the NACO adaptive optics compensation achieved nearly theoretical image sharpness, about 0.068 arcsec for this waveband.

 Spaceflight Now | Breaking News | Pluto meets triple star
One of the images obtained with the NAOS-CONICA (NACO) adaptive optics (AO) camera mounted on the ESO VLT 8.2-m YEPUN telescope at the Paranal Observatory in connection with a stellar occultation by Pluto on July 20, 2002.
A first evaluation of the NACO data indicates that the Paranal site "missed" the upper layers of Pluto's atmosphere by a mere 200 km or so - this is equivalent to no more than one hundredth of an arcsec as projected on the sky.
This effect, together with the large distance to the planet, manifests itself as a gradual decline of observed intensity of the stellar light, rather than an abrupt drop as this would be the case if the planet had no atmosphere.
