30 January 1998: While famous Comet Hale-Bopp continues its long voyage towards the outer reaches of the solar system, observations proceed with telescopes in the southern hemisphere. These research programmes aim at a better understanding of the further development of this very active comet as it moves away from the Sun and slowly cools. Among the key questions are for instance: "When will it cease to display a dust tail?" and "Will the nucleus undergo outbursts during which much fresh material will be dispensed into space, as this has occasionally happened by other comets (e.g. Halley)?"

29 January 1998: SOFI, ESO's new infrared imager/spectrometer, saw first light at the NTT telescope on December 6, 1997, as planned and less than two years after the start of its detailed design. The acronym stands for 'Son OF ISAAC', the larger Infrared Spectrometer And Array Camera being built by ESO for the VLT.

22 January 1998: This spring, teachers across Europe will enjoy support for exciting, novel educational projects on astronomy, navigation and environmental observations. The largely web-based and highly interactive SEA & SPACE programme makes it possible for pupils to perform field experiments and astronomical observations and to obtain and process satellite images. A contest will take the best pupils for one week to Lisbon (Portugal), to Europe's space port in Kourou (French Guyana) where the European launcher lifts off or to ESO's Very Large Telescope at the Cerro Paranal Observatory in Chile, the largest optical telescope in the world.

DEEP SKY DIVING WITH THE ESO NEW TECHNOLOGY TELESCOPE — Preparations for future cosmological observations with the VLT
13 January 1998: Within a few months, the first 8.2-meter Unit Telescope of the ESO Very Large Telescope (VLT) array will open its eye towards the sky above the Atacama desert. As documented by recent Press Photos from ESO, the construction work at the Paranal VLT Observatory is proceeding rapidly. Virtually all of the telescope components, including the giant Zerodur mirror, are now on the mountain.

19 December 1997: The present collection of twelve high-resolution photographic images illustrates the transport of the first VLT 8.2-m Zerodur mirror (M1) to Paranal. They are suitable for high-quality reproduction and complement the digital, less detailed ESO Press Photos 33a-f/97 which were published one week ago with information about this important event.

12 December 1997: Another historic event in ESO's Very Large Telescope Project has just occurred. The first giant mirror is on the mountain! The blanks for the four 8.2-metre VLT mirrors of Zerodur were produced by the Schott Glaswerke (Mainz, Germany) and have been polished at the REOSC factory (St. Pierre du Perray, France). For more information, see ESO Press Release 15/95. The first of the four mirrors left France in early November 1997 en route to Paranal. The transport was organized by the Gondrand company.

2 December 1997: The main structure of the ESO Very Large Telescope (VLT) has been designed, produced and assembled by an Italian consortium composed of Ansaldo Energia (Genova), European Industrial Engineering (Venice) and SOIMI (Milan). A total of four identical structures have been built, one for each of the four VLT 8.2-m Unit Telescopes.

24 November 1997: When is a minor object in the solar system a comet? And when is it an asteroid? Until recently, there was little doubt. Any object that was found to display a tail or appeared diffuse was a comet of ice and dust grains, and any that didn't, was an asteroid of solid rock. Moreover, comets normally move in rather elongated orbits, while most asteroids follow near-circular orbits close to the main plane of the solar system in which the major planets move.

22 October 1997: During the past month, there has been much action in many different areas at the ESO Paranal Observatory. Work has continued on the assembly of various components of the telescope structures and on the surface of the summit platform, as well as in connection with the maintenance and storage facilities near the base camp at the foot of the mountain.

8 October 1997: After having passed behind the Sun (as seen from the Earth), Comet Hale-Bopp is now again well visible to observers in the southern sky. Although this famous object is now three times farther away than when it passed its closest point to the Sun (the perihelion) on April 1, 1997, it is still quite bright, especially when compared to other comets that have been observed at the same distance. Its magnitude is now around 5, i.e. when seen in a dark sky it is just visible with the unaided eye. However, it is seen better through moderate-size binoculars and is of course still more interesting when observed with a large, professional telescope.

10 September 1997: In this continuing series of views from the ESO Paranal Observatory, most have been related to developments around the VLT telescopes and their enclosures. While this assembly work is very important and now rapidly progresses towards the crucial moment of First Light , other activities are also going on which will ensure the proper functioning of the small, isolated community at Paranal, in the middle of the extreme Atacama desert.

12 August 1997: One more important step within the ESO Very Large Telescope (VLT) project has just been successfully accomplished. After a journey of more than 12,000 km, the enormous coating plant for the 8.2-m VLT Zerodur mirrors has just arrived safely at the Paranal Observatory in the Atacama desert. Here it is now being installed in the Mirror Maintenance Building (MMB) , a large and complex structure that has been constructed next to the base camp, at the foot of the Paranal mountain.

8 August 1997: The installation of the ESO Very Large Telescope (VLT) at the Paranal Observatory in the Chilean Atacama desert continues at good pace. As the moment of first light of the first 8.2-metre telescope is getting closer, the assembly of the enormous, 400-ton mechanical structure proceeds according to schedule.
