New Observations of Comet Hale-Bopp from La Silla — Methanol and Hydrogen Cyanide Detected at Record Distance

22 October 1998: Observations of famous Comet Hale-Bopp continue with the 15-m Swedish-ESO Submillimetre Telescope (SEST) at the La Silla Observatory. They show amazingly strong activity of this unusual object, also at the present, very large distance from the Sun. The radio observations document in detail the release of various molecules from the comet's icy nucleus. Of particular interest is the observed emission from methanol (CH 3 OH) and hydrogen cyanide (HCN) molecules, never before detected in any comet this far away.

A Strange Supernova with a Gamma-Ray Burst — Important Observations with La Silla Telescopes

15 October 1998: Several articles appear today in the scientific journal Nature about the strange supernova SN 1998bw that exploded earlier this year in the spiral galaxy ESO184-G82 . These studies indicate that this event was linked to a Gamma-Ray Burst and may thus provide new insights into this elusive phenomenon. Important observations of SN 1998bw have been made with several astronomical telescopes at the ESO La Silla Observatory by some of the co-authors of the Nature articles [1]. The measurements at ESO will continue during the next years.

FORS1 at the VLT UT1: First Spectra Obtained — First commissioning phase successfully completed

7 October 1998: The FORS Team at Paranal has concluded the first phase of the extensive FORS1 commissioning tests at the first 8.2-m VLT Unit Telescope (UT1), successfully and according to the plan. Although this work was primarily aimed at testing the technical performance of this new instrument, it has also been possible to obtain some spectacular images already at this early stage. And now, for the first time, spectra [1] have also been observed with the VLT.

A Forceful Demonstration by FORS — New VLT Instrument Provides Impressive Images

23 September 1998: Following a tight schedule, the ESO Very Large Telescope (VLT) project forges ahead - full operative readiness of the first of the four 8.2-m Unit Telescopes will be reached early next year. On September 15, 1998, another crucial milestone was successfully passed on-time and within budget. Just a few days after having been mounted for the first time at the first 8.2-m VLT Unit Telescope (UT1), the first of a powerful complement of complex scientific instruments, FORS1 ( FO cal R educer and S pectrograph), saw First Light . Right from the beginning, it obtained some excellent astronomical images. This major event now opens a wealth of new opportunities for European Astronomy.

Guiding the Giant — New ESO Survey Provides Targets for the VLT

4 August 1998: Giant astronomical telescopes like the ESO Very Large Telescope (VLT) must be used efficiently. Observing time is expensive and there are long waiting lines of excellent research programmes. Thus the work at the telescope must be very well prepared and optimized as much as possible - mistakes should be avoided and no time lost! Astronomers working with the new 8-m class optical/infrared telescopes must base their observations on detailed lists of suitable target objects if they want to perform cutting-edge science. This is particularly true for research programmes that depend on observations of large samples of comparatively rare, distant objects. This type of work requires that extensive catalogues of such objects must be prepared in advance. One such major catalogue - that will serve as a very useful basis for future VLT observations - has just become available from the new ESO Imaging Survey (EIS).

VLT Quick Views of Spacecraft Targets

31 July 1998: The first VLT 8.2-m telescope (UT1) is now undergoing a "Commissioning Phase" during which all systems are thoroughly tested and further tuned. Although priority is given to technical work, some astronomical images have been obtained during the recent weeks. Some days ago, during short periods when no technical tests were scheduled, "quick shots" were obtained of two comets, both of which are designated targets for space missions.

First VLT Excursion into Deep Space

31 July 1998: During the continuing "Commissioning Phase" of the first VLT 8.2-m telescope (UT1), it has been possible to carry out some astronomical observations from time to time. Thanks to its large light-gathering capacity and excellent optical quality, the UT1 is particularly well suited to image very faint and distant objects. To assess this important potential for front-line research in more quantitative terms, it was therefore decided to perform some preliminary tests in this direction, already at this early moment.
