Book Description
For the last twenty years astronomy has been developing dramatically. Until the nineteen-fifties, telescopes, spectrometers, and photographic plates consti tuted a relatively simple set of tools which had been refined to a high degree of perfection by the joint efforts of physicists and astronomers. Indeed these tools helped at the birth of modern astrophysics: the discovery of the expan sion of the Universe. Then came radioastronomy and the advent of electronics; the last thirty years have seen the application to astrophysics of a wealth of new experimental techniques, based on the most advanced fields of physics, and a constant interchange of ideas between physicists and astronomers. Last, but not least, modern computers have sharply reduced the burden of dealing with the information painfully extracted from the skies, whether from ever scarce photons, or from the gigantic data flows provided by satellites and large telescopes. The aim of this book is not to give an extensive overview of all the tech niques currently in use in astronomy, nor to provide detailed instructions for preparing or carrying out an astronomical project. Its purpose is methodologi cal: photons are still the main carriers of information between celestial sources and the observer. How we are to collect, sample, measure, and store this infor mation is the unifying theme of the book. Rather than the diversity of tech niques appropriate for each wavelength range, we emphasize the physical and mathematical bases which are common to all wavelength regimes.

Book Description
Since the first edition of this book appeared in 1990, planetology has seen a number of fascinating discoveries that have increased our knowledge of the Solar System. These have come from both ground- and space-based observa tional programmes. Although some space probe missions have ended in fail ure, even they have added to our store of information about the planetary environment. The Galileo probe, despite being crippled by its incompletely deployed main antenna, has already achieved some spectacular results. For the first time we have obtained pictures of asteriods, with the images that Galileo returned of Gaspra, Ida, and the latter's satellite, Dactyl. The main objective, the drop ping of an instrumented capsule into Jupiter's atomosphere, and prolonged in-situ investigation of the planet, will take place at the end of 1995. Saturn's turn will come early in the next century with the Cassini mission (to be launched in 1997), which will study the planet for an extended period and attempt to land the Huygens probe on the surface of Titan. NASA's Magellan mission proved to be a great success, with its highly detailed radar mapping of the surface, and atmospheric studies. The exploration of Mars was less fortunate with the failure of both spaceprobes of the Soviet Phobos mission, as well as NASA's Mars Observer probe. Despite this set back, plans are in hand for future, collaborative exploration of the planet, using both surface stations (possibly active rovers), surface penetrators and balloon probes, as well as orbiters.

Book Description
An introduction to practical astrometry, dealing with the determination of positions, motions, distances and dimensions of celestial bodies ranging from quasars to artificial satellites. For this 2nd edition, the release of the Hipparcos and Tycho catalogs, the rise in CCD astrometry and the adoption of a new celestial reference frame by the IAU led to a significant modification of the text. And, especially, the outlook for astrometry has been completely rewritten.

Book Description
From the reviews: Astronomy and Astrophysics Abstracts has appeared in semi-annual volumes since 1969 and it has already become one of the fundamental publications in the fields of astronomy, astrophysics and neighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. ... The abstracts are classified under more than hundred subject categories, thus permitting a quick survey of the whole extended material. The AAA is a valuable and important publication for all students and scientists working in the fields of astronomy and related sciences. As such it represents a necessary ingredient of any astronomical library all over the world." Space Science Reviews #1 "Dividing the whole field plus related subjects into 108 categories, each work is numbered and most are accompanied by brief abstracts. Fairly comprehensive cross-referencing links relevant papers to more than one category, and exhaustive author and subject indices are to be found at the back, making the catalogues easy to use. The series appears to be so complete in its coverage and always less than a year out of date that I shall certainly have to make a little more space on those shelves for future volumes."
