The Explanatory Supplement to the Astronomical Almanac offers explanatory material, supplemental information, and detailed descriptions of the computational models and algorithms used to produce The Astronomical Almanac, which is an annual publication prepared jointly by the US Naval Observatory and Her Majesty's Nautical Almanac Office in the UK. Like The Astronomical Almanac, The Explanatory Supplement provides detailed coverage of modern positional astronomy. Chapters are devoted to the celestial and terrestrial reference frames, orbital ephemerides, precession, nutation, Earth rotation, and coordinate transformations. These topics have undergone substantial revisions since the last edition was published in 1992. Astronomical positions are intertwined with timescales and relativity in The Astronomical Almanac, so related chapters are provided in The Explanatory Supplement. The Astronomical Almanac also includes information on lunar and solar eclipses, physical ephemerides of solar system bodies, and calendars, so The Explanatory Supplement expounds upon each of these topics as well. The book is written at a technical, but non-expert level. As such, it provides an important reference for a full range of users including astronomers, engineers, navigators, surveyors, space scientists, and educators.

Every city dweller is aware that we are seeing fewer stars at night due to the increasing amount of artificial lighting. But that is just the tip of the iceberg, as far as the loss of natural nocturnal darkness is concerned. Humans and animals worldwide are now suffering from the disrupted rhythm of day and night due to extreme lighting at night. In humans this can lead to illness and increased stress. Hitherto only known to experts, this book is the first to comprehensively treat the entire phenomenon of light pollution. Richly illustrated using unusual images taken from the TV documentation "The Dark Side of Light" by Anja Freyhoff and Thomas Uhlmann, this book is for anyone interested in a harmonious coexistence between humans and nature and a healthy work/life rhythm.

Easy PC Astronomy is the perfect book for everyone who wants to make easy and accurate astronomical calculations. The author supplies a simple but powerful script language called AstroScript on a disk, ready to use on any IBM PC-type computer. Equipped with this software, readers can compute complex but interesting astronomical results within minutes: from the time of moonrise or moonset anywhere in the world on any date, to the display of a lunar or solar eclipse on the computer screen--all within a few minutes of opening the book! The Sky Graphics feature of the software displays a detailed image of the sky as seen from any point on earth--at any time in the future or past--showing the constellations, planets, and a host of other features. Readers need no expert knowledge of astronomy, math or programming; the author provides full details of the calculations and formulas, which the reader can absorb or ignore as desired, and a comprehensive glossary of astronomical terms. Easy PC Astronomy is of immediate practical use to beginning and advanced amateur astronomers, students at all levels, science teachers, and research astronomers. Peter Duffett-Smith is at the Cavendish Laboratory of the University of Cambridge and is the author of Astronomy with Your Personal Computer (Cambridge University Press, 1990) and Practical Astronomy with Your Calculator (Cambridge University Press, 1989).

Astrometry encompasses all that is necessary to provide the positions and motions of celestial bodies. This includes observational techniques, instrumentation, processing and analysis of observational data, reference systems and frames, and the resulting astronomical phenomena. Astrometry is fundamental to all other fields of astronomy, from the pointing of telescopes, to navigation and guidance systems, to distance and motion determinations for astrophysics. In the last few decades, new observational techniques have enabled improvements in accuracy by orders of magnitude. Starting from basic principles, this 2004 book provides the fundamentals for this new astrometry at milli- and micro-arcsecond accuracies. Topics include: basics of general relativity; co-ordinate systems; vectors, tensors, quaternions, and observational uncertainties; determination and use of the celestial and terrestrial reference systems and frames; applications of new observational techniques; present and future star catalogues and double star astrometry. This comprehensive reference will be invaluable for graduate students and research astronomers.

The Solar System is a complex and fascinating dynamical system. This is the first textbook to describe comprehensively the dynamical features of the Solar System and to provide students with all the mathematical tools and physical models they need to understand how it works. It is a benchmark publication in the field of planetary dynamics and destined to become a classic. Clearly written and well illustrated, Solar System Dynamics shows how a basic knowledge of the two- and three-body problems and perturbation theory can be combined to understand features as diverse as the tidal heating of Jupiter's moon Io, the origin of the Kirkwood gaps in the asteroid belt, and the radial structure of Saturn's rings. Problems at the end of each chapter and a free Internet Mathematica® software package are provided. Solar System Dynamics provides an authoritative textbook for courses on planetary dynamics and celestial mechanics. It also equips students with the mathematical tools to tackle broader courses on dynamics, dynamical systems, applications of chaos theory and non-linear dynamics.
