16 March 1988: New and exciting observations at the European Southern Observatory have probed the interstellar space around last year's bright supernova SN 1987A in the Large Magellanic Cloud (LMC)

8 December 1987: The representatives of the eight member states (Belgium, Denmark, the Federal Republic of Germany, France, Italy, the Netherlands, Sweden and Switzerland) agreed that the European Southern Observatory shall embark upon the realization of this marvelous instrument. This decision expresses Europe's confidence in the ambition of her astronomical community and the ingenuity of her high-tech industry; together they will ensure that Europe will be second to none in the exploration of the Universe for a long time to come. The VLT is an essential complement of Europe's astronomical research activities from space vehicles.

5 November 1987: The prototype of a new class of astrophysical phenomena has now been interpreted. Studies of other objects of the same type will open entirely new vistas in the exploration of the nature of distant galaxies.

29 September 1987: ESO announces the establishment of the world's first system for interactive remote control of ground-based telescopes on another continent.

10 September 1987: A newly discovered quasar (eso8712) has been found to have a record redshift [1] of 4.11 and is therefore the hitherto most distant known object in the Universe.

8 July 1987: The first full-scale, international meeting about the bright Supernova 1987A in the Large Magellanic Cloud (LMC) was held at the European Southern Observatory in Garching near Munich on July 6 - 8, 1987. ESO was a natural meeting place in view of the many different observational studies of SN 1987A which have been carried out at the ESO La Silla observatory.

25 May 1987: An exhibition about the European Southern Observatory will be open to the public at the Heysel Planetarium, Brussels, Belgium, on June 6 - 15, 1987 (all days, also during the weekends, from 10:00 to 16:30). It has been organized in a collaboration between ESO, the Brussels Planetarium and the Belgian National ESO Committee.

31 March 1987: “This supernova is different from all others observed so far".That is the unanimous conclusion of astronomers who have observed supernova 1987A in the Large Magellanic Cloud (LMC) with ESO telescopes since the explosion in late February (see ESO 04/87 and ESO 05/87). The collective results from the ESO La Silla observatory of no less than 38 astronomers have now been submitted to the European journal Astronomy & Astrophysics where they will appear in six "Letters to the Editor'' in the May(I) 1987 issue. These articles cover astrometry, optical and infrared photometry, polarimetry, optical and infrared spectroscopy and high-resolution spectroscopy; they are immediately available in ESO Preprint no. 500 (March 30, 1987) which can be obtained by request to the ESO Information and Photographic Service.

3 March 1987: One week after the explosion of a bright supernova (1987A) in the Large Magellanic Cloud (ESO 04/87), and after intensive observations at the European Southern Observatory and elsewhere in the southern hemisphere, it is now possible to draw several important conclusions about this unique event.

25 February 1987: Astronomers all over the world are highly excited about the sudden explosion of a supernova in the Large Magellanic Cloud (LMC), a small satellite galaxy to our own Milky Way Galaxy. The LMC is the nearest, external galaxy; its distance is only about 180.000 light years.

5 January 1987: Based on observations obtained at the European Southern Observatory (ESO), astronomers at the Space Telescope Science Institute (STScI) have uncovered the strongest evidence yet for the presence of a giant planetary or protoplanetary system accompanying a nearby star [1].

4 December 1986: An unusual "astro-detective" investigation came to a successful conclusion today, when a long lost planet in the solar system was finally found again. This planet which carries the name "MALLY" and the number "1179" had been missing for 55 years, and was last seen in 1931. Its faint image was now identified on photographic plates obtained with the ESO Schmidt telescope during a dedicated search programme. The accurate orbit of MALLY in the solar system [1] has now been determined, ensuring that MALLY will never be lost again. This work was carried out by Drs. Lutz Schmadel of the Astronomisches Rechen-Institut in Heidelberg, FRG, and Richard M. West of the European Southern Observatory.

5 November 1986: For the first time, an accurate and direct determination of the diameters of the outermost planet Pluto and its moon, Charon, has been made. On the basis of measurements of light changes during eclipses, Pluto was found to have a diameter of 2200±140 km. Charon is approximately half the size; the diameter is 1160±100 km. Charon moves in an almost perfectly circular orbit around Pluto; the orbital period is 6.38 days and the mean distance is 19400 km.

4 October 1986: The ESO Very Large Telescope (VLT) project [1] has passed an important milestone on its way towards realization. This week, more than 80 leading scientists and engineers from the ESO member countries (and beyond) made a detailed assessment of this ambitious project, which aims at the construction of the world's largest optical telescope. There was unanimous agreement that the present concept is near the optimal, that it is technologically feasible and can be realized within approximately 10 years after funding has been decided upon, and that it will allow European astronomers to perform new and spectacular investigations of the universe, unparalleled elsewhere. Completion is aimed at in 1997 but part of the VLT may become operational already in 1993.

6 March 1986: This spectacular image of Comet Halley, rising above the eastern horizon, was obtained at the La Silla observatory during the morning of February 22. It was made by superposing 6 exposures (total 9 min.) with the wide-field CCD camera which was specially designed for the study of Comet Halley. The image measures 5.5 x 9 degrees across and covers the 500 - 1100 nm spectral region (green near infrared). Each pixel (image element) measures 31 x 31 arc-seconds.

26 February 1986: 23 February was the last morning when Comet Halley could be seen in a dark sky. During the next two weeks, the moonshine will hamper further detailed observations of the incredibly complicated tail structure which was recently detected at the European Southern Observatory on La Silla.

18 February 1986: After the successful recovery of Comet Halley on 15 February, at the European Southern Observatory (ESO), observations have been made at the ESO La Silla Observatory every morning since. Accurate positions of the comet continue to be measured and transmitted within a few hours to the spacecraft centers in Darmstadt, Moscow, Tokyo and Pasadena. This is an important contribution to the accurate navigation of the five spacecrafts, including the European Space Agency's GIOTTO, now heading towards an encounter with Halley in early March.

16 February 1986: The first observation of Comet Halley after its passage behind the Sun was made at ESO La Silla by ESO Staff Astronomer R.M. West and Belgian astronomer H. Debehogne.

13 January 1986: ESO has established a new service, which will from now on handle all public relations matters. It is located at the ESO Headquarters in Garching, FRG and can be reached as indicated below.
