StarGuides Plus represents the most comprehensive and accurately validated collection of practical data on organizations involved in astronomy, related space sciences and other related fields. This invaluable reference source (and its companion volume, StarBriefs Plus) should be on the reference shelf of every library, organization or individual with any interest in these areas. The coverage includes relevant universities, scientific committees, institutions, associations, societies, agencies, companies, bibliographic services, data centers, museums, dealers, distributors, funding organizations, journals, manufacturers, meteorological services, national norms & standard institutes, parent associations & societies, publishers, software producers & distributors, and so on. Besides astronomy and associated space sciences, related fields such as aeronautics, aeronomy, astronautics, atmospheric sciences, chemistry, communications, computer sciences, data processing, education, electronics, engineering, energetics, environment, geodesy, geophysics, information handling, management, mathematics, meteorology, optics, physics, remote sensing, and so on, are also covered where appropriate. After some thirty years in continuous compilation, verification and updating, StarGuides Plus currently gathers together some 6,000 entries from 100 countries. The information is presented in a clear, uncluttered manner for direct and easy use.

First observed by Galileo, Saturn lies in the distant reaches of the solar system; it is the sixth planet, a gaseous giant between Jupiter and Uranus. It takes its name from the mythological father of Jupiter and Roman god of agriculture. Because of the famous circle of rings Saturn is one of the most well-regarded occupants of the galaxy. Despite their continuous appearance from Earth, the rings are actually space dust and debris trapped by Saturn's gravitational pull, a fact garnered from several satellite passes and telescope observations. The origin of Saturn's rings, however, remains a mystery. Apart from the rings, we also are aware of its moon system, with the most intriguing planetoid called Titan, itself having been the subject of science fiction speculation as a home to life. Saturn has been visited by Pioneer 11 and the two Voyager probes, with Cassini slated to arrive in 2004. Our study of this most intriguing planet will continue into the foreseeable future, with the hopes of resolving the mysteries it hides. This book provides a thorough and interesting overview of Saturn, from its initial observation centuries ago to the contemporary satellite fly-bys. Anyone captivated by the mysteries of space and the wonders of Saturn needs to understand the background covered here. After the overview is a substantial and carefully selected set of abstracts of literature pertaining to Saturn, with easy access then given through author, title, and subject indexes.

The First Edition of The Sun from Space, completed in 1999, focused on the early accomplishments of three solar spacecraft, SOHO, Ulysses, and Yohkoh, primarily during a minimum in the Sun’s 11-year cycle of magnetic activity. The comp- hensive Second Edition includes the main ndings of these three spacecraft over an entire activity cycle, including two minima and a maximum, and discusses the signi cant results of six more solar missions. Four of these, the Hinode, RHESSI, STEREO, and TRACE missions were launched after the First Edition was either nished or nearly so, and the other two, the ACE and Wind spacecraft, extend our investigations from the Sun to its varying input to the Earth. The Second Edition does not contain simple updates or cosmetic patch ups to the material in the First Edition. It instead contains the relevant discoveries of the past decade, integrated into chapters completely rewritten for the purpose. This provides a fresh perspective to the major topics of solar enquiry, written in an enjoyable, easily understood text accessible to all readers, from the interested layperson to the student or professional.

"Astronomy and Astrophysics Abstracts" appearing twice a year has become oneof the fundamental publications in the fields of astronomy, astrophysics andneighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. The abstracts are classified under more than a 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.

The ability of storing, managing, and giving access to the huge quantity of data collected by astronomical observatories is one of the major challenges of modern astronomy. At the same time, the growing complexity of data systems implies a change of concepts: the scientist has to manipulate data as well as information. Recent developments of the `WorldWideWeb' bring interesting answers to these problems. The book presents a wide selection of databases, archives, data centers, and information systems. Clear and up-to-date descriptions are included, together with their scientific context and motivations. Audience: This volume provides an essential tool for astronomers, librarians, data specialists and computer engineers.

All papers have been peer reviewed. This conference was organized for an anniversary moment to bring together scientists from the main fields of astrophysics and space science. It was a celebration of the 50 years from the start of the solar observations at Bucharest Observatory and the beginning of astrophysics research in Romania. Topics discussed include: solar atmosphere, magnetic structure on the Sun, solar and stellar winds, waves, oscillations and cyclicities, astroseismology, stellar astrophysics, and extragalactic astronomy and cosmology.
