Comet nuclei are the most primitive bodies in the solar system. They have been created far away from the early Sun and their material properties have been altered the least since their formation. Thus, the composition and structure of comet nuclei provide the best information about the chemical and thermodynamic conditions in the nebula from which our solar system formed. In this volume, cometary experts review a broad spectrum of ideas and conclusions based on in situ measurement of Comet Halley and remote sensing observations of the recent bright Comets Hale-Bopp and Hyakutake. The chemical character of comet nuclei suggests many close similarities with the composition of interstellar clouds. It also suggests material mixing from the inner solar nebula and challenges the importance of the accretion shock in the outer nebula. The book is intended to serve as a guide for researchers and graduate students working in the field of planetology and solar system exploration. Several special indexes focus the reader's attention to detailed results and discussions. It concludes with recommendations for laboratory investigations and for advanced modeling of comets, the solar nebula, and the collapse of interstellar clouds.

The study of comets is a field that has seen tremendous advances in recent years, far surpassing the knowledge reflected in the original Comets volume published as part of the Space Science Series in 1982. This new volume, with more than seventy contributing authors, represents the first complete overview of comet science in more than a decade and contains the most extensive collection of knowledge yet assembled in the field. Comets II situates comet science in the global context of astrophysics for the first time by beginning with a series of chapters that describe the connection between stars and planets. It continues with a presentation of the formation and evolution of planetary systems, enabling the reader to clearly see the key role played in our own solar system by the icy planetesimals that were the seeds of the giant planets and transneptunian objects. The book presents the key results obtained during the 1990s, in particular those collected during the apparition of the exceptional comets C/Hyakutake and C/Hale-Bopp in 1996-1997. The latest results obtained from the in situ exploration of comets P/Borrelly and P/Wild 2 are also discussed in detail. Each topic of is designed to be accessible to students or young researchers looking for basic, yet detailed, complete and accurate, information on comet science. With its emphasis on the origin of theories and the future of research, Comets II will enable scientists to make connections across disciplinary boundaries and will set the stage for discovery and new understanding in the coming years.

Comet Hale-Bopp defines a milestone event for cometary science: it is the first "really big" comet observed with modern equipment on the ground and from space and due to that; it is considered the new reference object in cometary sciences. At the beginning of a new era in spacecraft exploration of comets and five years after Hale-Bopp's perihelion passage these proceedings of invited and contributed papers for IAU Colloquium 186 "Cometary Science after Hale-Bopp" review the state-of-the-art knowledge on comets, the icy, dusty and most primordial left-overs of the formation disk of our own solar system. This is the first volume with invited review papers. A second volume with contributed papers is published in ISBN 1-4020-0978-X.

Have you ever wondered what comets are and why astronomers spend so much time studying them? Now, a comet expert and an astronomical historian have come together to produce this unique book. Using their several decades of teaching experience, the authors have concisely presented the information you need to comprehend these majestic apparitions that grace our night skies. No mathematical proficiency is needed. In fact, this book doesn't contain a single equation. Comets are cosmic Rosetta stones, bridging our current knowledge by digging back to the earliest days of our solar systems. How did life arise on Earth? Did comets play a significant role in bringing water and the necessary organic matter to our early Earth? How about the dinosaurs? Were they driven to extinction by a cometary impact 66 million years ago? Comets may be both the enablers and destroyers of life on Earth as we know it. These are some of the tantalizing questions discussed here. If you so desire, steps are given to join the ranks of amateur comet hunters. Astronomy is one of the last sciences where amateurs play a significant role. Your reward for discovery? A comet officially bearing your name in the history books. The next great comet is on its way, we just do not know when it will arrive. Armed with this book, you will be ready to enjoy this unforgettable event.
