Abstract:
French astronomers have been studying the kinematics of interstellar hydrogen for more than a decade, mainly by means of Fabry-Perot interferometers (cf. the article by M. Duval in Messenger No. 9). Recently, Drs. J. Boulesteix and G. Courtes trom Laboratoire d'Astronomie Spatiale in Marseille travelled to La Silla and obtained new and spectacular results about the hydrogen in some nearby southern galaxies.

Abstract:
Trailblazing observations of stars in late stages of their initial formation were earried out some months ago by two astronomers from the Landessternwarte Heidelberg-Königstuhl, FRG, Drs. C. Bertout and B. Wolf. Speetroseopy with the ESO 1.5 m teleseope on La Si/la during twelve eonseeutive nights revealed dramatie speetral ehanges, and simultaneous photometrie observations at the new observatory near San Pedro Martir, Baja California, Mexieo, are now being redueed.

Abstract:
About 60 astronomers attended the workshop on IR astronomy jointly organized by the Stockholm Observatory and ESO on the island of Utö on June 20-22, 1978. The number of participants, significantly larger than originally planned, was in itself a sign of the increasing interest among the European astronomers in the scientific and observational aspects of ground-based IR astronomy.

Abstract:
New satellite data have provided ground-based optieal astronomers with a large amount of extremely interesting work in eonneetion with X-ray binary stars. Speetroseopie and photometrie observations are urgently needed to further unravel the nature of these strange objeets. The present report by Drs. Godelieve Hammersehlag-Hensberge and Edward P.J. van den Heuvel of the Astronomical Institute of the University of Amsterdam, the Netherlands, summarizes four years of painstaking observations of one of the brightest stars identified with an X-ray souree. Their thorough study has already revealed some very interesting details about this binary system.

AA(ESO Scientific Group in Geneva)
Abstract:
It is becoming increasingly c1ear that strange things happen in many galaxy nuclei and thattheir study is of extreme importance for our understanding of the behaviour of matter. Observations from satellites and with large telescopes have yielded new and often unexpected results and the possibility of the existence of black holes (or even more exotic objects) in the centres of active galaxies is now taken seriously by most astronomers. Dr. Robert Fosbury, who joined the ESO Scientific Group in Geneva in 1977, has been pursuing for a long time the study of galaxy nuclei with some of the world's largest telescopes. He gives some examples of recent work with the ESO 3.6 m telescope.

Abstract:
Dr. Irena Semeniuk is a senior lecturer at the Astronomical Observatory of the Warsaw University, Poland, and joined the ESO Scientific Group in October 1977 with a one-year fellowship. She is interested in extragalactic astronomy (distribution of galaxies in clusters) as weil as in cataclysmic variables. She recently observed at La Silla and was very happy to catch one of these stars in a "superburst".

Abstract:
During the past months, astronomers have been busy at the IUE ground station near Madrid. Dr. Massimo Tarenghi was the first ESO astronomer to use this unique ultraviolet satellite to observe extragalactic objects. This is the first, brief report about his exciting observations, together with Dr. Perola from Milan. We expect to bring further news about the IUE in the next issue of the Messenger.

Abstract:
A little over a year ago, Drs. Claude Chevalier and Sergio Il0vaisky reported the optical identification of the X-ray source LMC X-4 (cf. Messenger No. 9, p. 4). Now, together with Dr. Christian Motch, also from Observatoire de Meudon, France, they have succeeded in measuring optical pulses in a 19m star with the same 'period as the southern X-ray source 4U 1626-67, and therefore identical with this source. To obtain a high time-resolution, O~8, it was necessary to use the 3.6 m telescope. Contrary to other X-ray sourees, no Doppler shift has yet been detected in 4U 1626-67.

Abstract:
There is a renewed interest in the Solar System and its planets. Incredible photos are transmitted back trom distant space probes and on-site physical investigations have become possible. An increasing number ot new planets are being disco vered with large, ground-based telescopes. However, most ot the known objects lie in or near the plane ot the Earth's orbit, the Ecliptic. Little is known about the objects that presumably exist high above or tar below this plane. How many are there and how did they get there? Drs. Lutz Schmadel and Joachim Schubart trom Astronomisches Recheninstitut in Heidelberg, Fed. Rep. ot Germany, describe a search programme with the ESO Schmidt telescope that aims at the discovery ot out-ot-the-Ecliptic minor planets.
