In May 1976, when one of us was temporarily associated with Stras- bourg Observatory for lecturing on distance determination methods (Heck 1978), Pierre Lacroute - then in his last year as Director there - mod- estly requested comments on a project he had been cherishing for quite a few years, and which he had been presenting to visitors and colleagues: an astrometric satellite.
In the early years of the twentieth century, Victor Hess of Germany flew instruments in balloons and so discovered in 1912 that an extra-~errestial radiation of unknown origin is incident on the earth with an almost constant intensity at all times.
Most papers in this book were presented at the SOHO-9 Workshop 'Helioseismic Diagnostics of Solar Convection and Activity', held on 12-15 July 1999 at Stanford University, California, U.
th The 4 ESO CCO Workshop, Optical Detectors for Astronomy, was held during September 13-16, 1999 at its usual location, the headquarters of the European Southern Observatory in Garching, Germany.
This book contains the Proceedings of the first 'Rencontres de l'Observatoire' which was held at the Meudon campus of the Paris Observatory on September 21-25, 1998.
In May 1998 a hundred renowned scientists from 20 different countries met at the Max-Planck-Institut fur Aeronomie to communicate their latest results and ideas in astrophysical and space plasma, as a follow-up to previous similar meetings which were held in Varenna, Abastumai, Potsdam, Toki and Guaruja.
A few years after the publication of The Physics of Star Formation and Early Stellar Evolution, we received a request from the publisher for an up- dated second edition of this popular reference book.
Astronomy Across Cultures: A History of Non-Western Astronomy consists of essays dealing with the astronomical knowledge and beliefs of cultures outside the United States and Europe.
IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) is the first NASA MIDEX mission and the first mission dedicated to imaging the Earth's magnetosphere.
The present sixth volume of ISSI Space Sciences Series is the outcome of the most ambitious study project of ISSI hitherto, that on 'Source and Loss Processes of Magnetospheric Plasma'.
The "e;Non-Sleeping Universe"e; was a conference conceived to commemorate the opening of the new building of the Centro de Astroffsica da U niversidade do Porto (CAUP).
It is with great joy that we present a collection of essays written in honour of Jayant Vishnu Narlikar, who completed 60 years of age on July 19, 1998, by his friends and colleagues, including several of his for- mer students.
For almost three decades since Mariner 2 flew by the planet in December 1962, Venus has been the subject of intense investigation by both the Soviet and American space programs.
The Galactic cosmic rays have far-reaching effects on the interstellar medium, and they are, in turn, profoundly affected by the particles and fields in space.
This book reports the Proceedings of the NATO Advanced Research Workshop on "e;An- gular Momentum Evolution of Young Stars"e; held from 17 to 21 September 1990 at Noto, Italy.
This book represents the proceedings from the NATO sponsored Advanced Research Workshop entitled "e;Observational Tests of Inflation"e; held at the University of Durham, England on the 10th-14th December, 1990.
When I became President of International Astronomical Union Commission 44 for the triennial period 1985-1988, several members of the Organizing Committee and I agreed that it would be a good idea for our Commission to host a conference on observatories in space in view of their increasingly important role in astronomi cal research.
A few years ago, a motivation for organizing one more IAU Symposium on star for- mation in Grenoble, was the anticipated completion of the IRAM interferometer on the Plateau de Bures, close to Grenoble.
From the beginning of Space Astronomy, the Extreme Ultraviolet band of the spectrum (roughly defined as the decade in energy from 90-900 A) was deemed to be the `unobservable ultraviolet'.
As in the days following Skylab, solar physics came to the end of an era when the So- lar Maximum Mission re-entered the earth's atmosphere in December 1989.
Minor bodies in the Solar System, though representing only a small fraction of the mass in the Solar System, may well play a fundamental role in terrestrial evolution.
