Comets are small bodies, but of great cosmic relevance. Given its pristine nature, they may preserve valuable and unique information on thechemical and physical processes that took place in theearly solar system, and that may be occurring in the formation of other planetary systems. They might have even played a very important role in the origin of life on Earth. Beyond that, since ancient times comets have inspired awe, superstition, and also curiosity anddebate. Their sudden apparitions challenged the long-held view of the immutability of the heavens, which triggered a long debate on whether comets had a heavenly or terrestrial nature. Therefore, comets have a prominent role in the history of scienti?cthought, that goes back to the most ancient civilizations. The last apparition of comet Halley in 1986 was a landmark since it arouse a great expectation in the scienti?c community and in the public at large. For the ?rst time, a ?otilla of spacecrafts visited a comet. Agreat number of popular and technical books were written on Halley, and comets in general, around the mid-eighties. The interest in comets never subsided after Halley's passage which is re?ected in the large volume of printed material on these bodies. I have taken the challenge to write a new book on comets that summarizes most of the recent advances on thesubject, including my own workdeveloped during the last 25 years.

Research on extrasolar planets is one of the most exciting fields of activity in astrophysics. In a decade only, a huge step forward has been made from the early speculations on the existence of planets orbiting "other stars" to the first discoveries and to the characterization of extrasolar planets. This breakthrough is the result of a growing interest of a large community of researchers as well as the development of a wide range of new observational techniques and facilities.

Based on their lectures given at the 31st Saas-Fee Advanced Course, Andreas Quirrenbach, Tristan Guillot and Pat Cassen have written up up-to-date comprehensive lecture notes on the "Detection and Characterization of Extrasolar Planets," "Physics of Substellar Objects Interiors, Atmospheres, Evolution" and "Protostellar Disks and Planet Formation." This book will serve graduate students, lecturers and scientists entering the field of extrasolar planets as detailed and comprehensive introduction.

Multi-ring basins are large impact craters formed in the early history of planets. They critically affect the evolution of the planets and their satellites. The Moon offers an exceptional chance to study these phenomena and this book provides a comprehensive geological study using data from lunar landings and remote sensing of the Moon. The author covers the formation and development of basins and considers their chemistry and mineralogy. He studies their effects on the volcanic, tectonic and geological evolution of the planet, including the catastrophic consequence on the planetary climate and evolution of life. This study is lavishly illustrated with many spectacular, highly-detailed photographs and diagrams.

The birth and evolution of our solar system is a tantalizing mystery that may one day provide answers to the question of human origins. From Dust to Life tells the remarkable story of how the celestial objects that make up the solar system arose from common beginnings billions of years ago, and how scientists and philosophers have sought to unravel this mystery down through the centuries, piecing together the clues that enabled them to deduce the solar system's layout, its age, and the most likely way it formed. Drawing on the history of astronomy and the latest findings in astrophysics and the planetary sciences, John Chambers and Jacqueline Mitton offer the most up-to-date and authoritative treatment of the subject available. They examine how the evolving universe set the stage for the appearance of our Sun, and how the nebulous cloud of gas and dust that accompanied the young Sun eventually became the planets, comets, moons, and asteroids that exist today. They explore how each of the planets acquired its unique characteristics, why some are rocky and others gaseous, and why one planet in particular--our Earth--provided an almost perfect haven for the emergence of life. From Dust to Life is a must-read for anyone who desires to know more about how the solar system came to be. This enticing book takes readers to the very frontiers of modern research, engaging with the latest controversies and debates. It reveals how ongoing discoveries of far-distant extrasolar planets and planetary systems are transforming our understanding of our own solar system's astonishing history and its possible fate.

Including the abundance of information known prior to the return of Halley's comet, as well as the new information discovered since then, the science of comets is described here by order of its discovery.

It will be suitable for advanced undergraduates and graduate students of astronomy and planetary science. First Edition Hb (2001): 0-521-23906-0 First Edition Pb (2002): 0-521-27218-1

Instead of taking somebody's word for it about the basic size and distance statistics for the solar system, this book shows amateur astronomers how to measure these things for themselves. This is an enriching experience for any amateur astronomer - to understand and personally measure some fundamental astronomical quantities and distances.

A basic knowledge of geometry is required, but it is amazing how simple the geometry can be. Readers are led through the geometry as gently as possible - and in a light-hearted way - presuming that most non-academics will have half-forgotten most of their mathematics.

The practical astronomical equipment recommended is no more than a typical commercially-made amateur telescope and a camera of some sort - these days a webcam works very well. Apart from that all the reader will need is access to a computer, the know-how to download free software, and an enthusiasm to expand his knowledge of the basis of scientific astronomy.

Discs occur in a wide variety of astronomical contexts, ranging in size from planetary ring systems to galaxies. Because the dynamical problems posed by each type of disc are remarkably similar, the Astronomy Department of the University of Manchester decided to bring together experts in each area for a conference in December 1988. This book is a collection of the papers presented at the conference. It contains mainly review papers covering recent developments in both theory and observations of planetary ring systems, discs in star-forming regions, protoplanetary discs, accretion discs and galaxy discs presented by an expert in each field. The book also gives brief summaries of contributed papers outlining current research by many of the participants.

Almost thirty years after the Apollo missions, "Tranquillity Base," "Hadley Rille," or "Taurus-Littrow" are names still resonant with the enormous achievements represented by the lunar landings. But how did these places get their names? Who named Copernicus crater? Where did all those names on lunar maps come from, and what stimulated their selection? Ewen Whitaker traces the origins and evolution of the present-day systems for naming lunar features such as craters, mountains, valleys and dark spots. The connections between the prehistoric and historic names, and today's gazetteer are clearly described. Beautiful lunar maps spanning four centuries of progress wonderfully illustrate the unfolding of our ability to map the Moon. Rare, early photographs add to the sense of history. Comprehensive appendices and the bibliography make this delightful book a work of lasting reference and scholarship.

Volume 2 of the four-volume catalog of comets observed throughout history provides a complete summary of every comet seen during the nineteenth century.

Harold Hill's book is a unique collection of drawings published for the first time in this form. The illustrations are supplemented by text often taken from observing notes at the telescope. Astronomical drawing still has an important place alongside photography in the same way that photography has not supplanted the artist in the field of botany and ornithology. Indeed, because of movements in the Earth's atmosphere, astronomical images tend to shimmer even under the best possible conditions; drawings constructed by an artist who takes advantage of the fleeting moments of perfect vision are often more detailed than photographs. No one can fail to be impressed by the beauty and artistry of this work and, for the initiated, the accuracy and attention to detail is remarkable.

Babylon to Voyager and Beyond describes the fascinating story of planetary research from the time of the Babylonians and Ancient Greeks to the modern age of space exploration. In it, David Leverington outlines the key astronomical discoveries in their historical context, covering not only the successes but also the main failures. Babylon to Voyager and Beyond is written to be accessible to both amateur and professional astronomers, and those interested in the history of science. Extensively illustrated, the book concludes with a description of the extensive planetary discoveries made by spacecraft, and the discoveries of planets around other stars.

David Levy has held a lifelong passion for comets, and is one of the most successful comet discoverers in history. In this book he describes the observing techniques that have been developed over the years--from visual observations and searching, to photography, through to electronic charge-coupled devices (CCDs). He combines the history of comet hunting with the latest techniques, showing how our understanding of comets has evolved over time. This practical handbook is suitable for amateur astronomers, from those who are casually interested in comets and how to observe them, to those who want to begin and expand an observing program of their own. Drawing widely from his own extensive experience, Levy describes how enthusiastic amateurs can observe comets and try to make new discoveries themselves. David H. Levy is one of the word's foremost amateur astronomers. He has discovered seventeen comets, seven using a telescope in his own backyard, and had a minor planet, Asteroid 3673 Levy named in his honor. He is best known as the co-discoverer of the famous 1994 Shoemaker-Levy 9 comet. Levy is frequently interviewed in the media and succeeded Carl Sagan as science columnist for Parade magazine. He has written and contributed to a number of books, most recently David Levy's Guide to the Night Sky (Cambridge, 2001).

Since the discovery of the first exoplanet orbiting a main sequence star in 1995, nearly 500 planets have been detected, with this number expected to increase dramatically as new ground-based planetary searches begin to report their results. Emerging techniques offer the tantalizing possibility of detecting an Earth-mass planet in the habitable zone of a solar-type star as well as the exciting prospect of studying exoplanetary atmospheres that could reveal the presence of biomarkers, such as water vapor, oxygen, and carbon dioxide. Can we find the "Holy Grail" of exoplanets? Cutting-edge research may reveal the answer Written by internationally renowned scientists at the forefront of the field, Extra-Solar Planets: The Detection, Formation, Evolution and Dynamics of Planetary Systems presents powerful analytical tools and methods for investigating extra-solar planetary systems. It discusses new theories on planetary migration and resonant capture that elucidate the existence of "hot Jupiters." It also examines the astrophysical mechanisms required to assemble gas giant planets close to their parent star. In addition, the expert contributors describe how mathematical tools involving periodicity, chaos, and resonance are used to study the diversity and stability of observed planetary systems. By presenting the fundamental analyses that underpin modern studies of extra-solar planetary systems, this graduate-level book enables readers to thoroughly understand important recent developments and offers a platform for future research. It also improves readers' understanding of our own solar system and its place in the diverse range of planetary systems discovered so far.

This book integrates astronomical observations and theories with geophysical studies, presenting a comprehensive overview of the extraterrestrial matter that falls to Earth from space. Meteoroids are the main topic of the book, although cosmic dust, interplanetary matter and meteorites are also discussed. This work is of great value to researchers involved in the study of meteor phenomena.

Jupiter’s magnetosphere (the region of space in which Jupiter’s magnetic field influences the motion of charged particles) is the largest object in the solar system; it exhibits new phenomena and behaves, in some respects, like a pulsar. It is a magnetosphere whose physics is dominated by internal sources of plasma and energy. This book consists of twelve carefully interwoven articles written by leading space scientists who summarize our state of knowledge of the physics of the magnetosphere surrounding the planet Jupiter. Ground-based data as well as information from the Pioneer and Voyager spacecraft are used in developing both physical descriptions and theoretical understanding. Physics of the Jovian Magnetosphere is a valuable reference work for those doing research in magnetospheric physics and in a number of related disciplines.

Canadian academic Martin Beech has written a text that attempts to cross the line between science fiction and science fact. Put simply, his book details a method that just might be able to stop the Sun from losing its power and, ultimately, save humanity and the Earth itself. It investigates the idea that the distant future evolution of our Sun might be controlled (or 'asteroengineered') so that it maintains its present-day energy output rather than becoming a bloated red giant star: a process that would destroy all life on Earth.

This introduction to the use of radar for remote sensing of natural surfaces provides the reader with a thorough grounding in practical applications, focusing particularly on terrestrial studies that may be extended to other planets.

The force of gravity acting over eons has provided the solar system with an intricate dynamical structure, much of it revealed by recent space missions. This comprehensive introduction to the dynamical features of the solar system also provides all the mathematical tools and physical models needed for a complete understanding of the subject. Clearly written and well illustrated coverage 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 help students to fully develop their understanding of the subject. This volume provides an authoritative textbook for advanced undergraduate and graduate 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 nonlinear dynamics. Written by two leading figures in planetary dynamics, it is a benchmark publication in the field and destined to become a classic.

Cometography is the most complete and comprehensive collection of data on comets available. It comes in four self-contained sequential volumes and this, the first, covers ancient times through to the end of the eighteenth century. Cometography uses the most reliable orbits known to determine all the key parameters of each well observed comet. Cometography also provides nontechnical details to help the reader understand how the comet may have influenced various cultures at the time of its appearance. All the information in Cometography has been sourced directly from the original documents, including European monastic histories, Roman, Greek and Muslim texts, Chinese, Japanese and Korean scripts. In many cases, dates of important historical events can be corrected based on the appearance of a comet and identified using this book. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

Our space age technology enables global communication, navigation, and power distribution that has given rise to our 'smart', interconnected and spacefaring world. Much of the infrastructure modern society depends on, to live on Earth and to explore space, is susceptible to space weather storms originating from the Sun. The Second Edition of this introductory textbook is expanded to reflect our increased understanding from more than a dozen scientific missions over the past decade. Updates include discussions of the rapidly expanding commercial space sector, orbital debris and collision hazards, our understanding of solar-terrestrial connections to climate, and the renewed emphasis of human exploration of the Moon and Mars. It provides new learning features to help students understand the science and solve meaningful problems, including some based on real-world data. Each chapter includes learning objectives and supplements that provide descriptions of the science and learning strategies to help students and instructors alike.

Meteorites and Their Parent Planets provides an engrossing overview of a highly interdisciplinary field--the study of extraterrestrial materials. The second edition of this successful book has been thoroughly revised, and describes the nature of meteorites, where they come from, and how they get to Earth. Meteorites offer important insights into processes in stars and in interstellar regions, the birth of our solar system, the formation and evolution of planets and smaller bodies, and the origin of life. The first edition was immensely popular with meteorite collectors, scientists and science students in many fields, as well as amateur astronomers. In this second edition all of the illustrations have been updated and improved, many sections have been expanded and modified based on discoveries in the past decade, and a new final chapter on the importance of meteorites has been added. Everyone with an interest in meteorites will want a copy of this book.

In Wonders of the Solar System – the book of the acclaimed BBC TV series – Professor Brian Cox will take us on a journey of discovery where alien worlds from your imagination become places we can see, feel and visit.

In this series, Professor Brian Cox will introduce us to the planets and moons beyond our world, finding the biggest, most bizarre, most powerful natural phenomena. Using the latest scientific imagery along with cutting edge CGI and some of the most spectacular and extreme locations on Earth, Brian will show us Wonders never thought possible.

Employing his trademark clear, authoritative, yet down-to-earth approach, Brian will explore how these previously unseen phenomena have dramatically expanded our horizons with new discoveries about the planets, their moons and how they came to be the way they are.

MARSWALK ONE: First Steps on a New Planet addresses the question of why we should embark on a journey to Mars, documenting what the first human crew will do when they place their feet in the red dust of the planet. The book also addresses why we need to carry out these tasks and, more importantly, what a human crew could achieve that an automated mission could not. Understanding the clear benefits of sending a human crew to the surface of Mars, and how these benefits can be seen back on Earth, is the key to sustained long-term public and political support for the programme in terms of cash and commitment.

The book accepts that the journey will be made, but does not specify precisely when. Flight time, and how to get to and from the planet are discussed briefly, to understand why the suggested duration spent at Mars is reasonable.

The main objective of the work is to look at what science will be done on the surface a" supported by orbital operations a" and what hardware and technology will be employed to achieve the mission objectives. This analysis is drawn from previous experiences in manned and unmanned space programmes, including Apollo, Skylab, Salyut/Mir, Shuttle and ISS, Viking, Luna/Lunokhod, and recent Mars missions such as Pathfinder and Global Surveyor.

In addition, new interviews with key personalities involved in planning Martian exploration, and discussions about current thoughts on what we need to accomplish on Mars when we get there, will provide a lively and thought provoking account that could generate fresh debate.

When the decision is finally made to go to Mars, it will be made in the knowledge that most of the world knows why we aregoing and what benefits mankind will see for the effort. The authorsa (TM) primary objective is to begin this understanding.
