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.

We have now reached an exciting time in cometary research. With several missions launched or about to be launched in the near future, cometary research is rapidly being driven forward. This book describes the wealth of information known prior to the return of Halley's comet, and the new information discovered since then. It presents material on important background topics including observational techniques, plasma physics, celestial mechanics, the solar wind and cosmogony. The science of comets is described in order of its discovery, from tail phenomena to coma morphology through to the most recent findings from space missions. The relationship between comets and asteroids is discussed, and future space missions to investigate comets are described. This comprehensive text is a complete and up-to-date treatment of the subject, suitable for graduate and advanced undergraduate students of astronomy and planetary science.

Comet nuclei are the most primitive bodies in the solar system. They have been created far away from the early Sun and it is supposed that their material has been altered the least since their formation. The workshop was bringing together representatives of several scientific communities in the fields of interstellar clouds, star-forming regions, the solar nebula, and comets. The intent was to formulate the current understanding and interconnectivity of the various source regions of comet nuclei and their associated compositions and orbital characteristics. The goal was to better understand the survival of cometary materials (grains, molecules, free radicals, and atoms) from extrasolar sources (circumstellar shells and molecular clouds), their modifications in the solar nebula, and the effects of their properties on the formation and early physical and thermal evolution of the macroscopic bodies, the comet nuclei, in the various subnebulae. Closely associated is their transport into the outer solar system, the Kuiper belt and Oort cloud. The distinction between direct measurements, in situ or by remote sensing, of cometary material properties and properties derived from indirect means, deduced from laboratory studies and theoretical deductions, was emphasized with the aim to guide future investigations. The book is intended to serve as guide for researchers and graduate students working in the field of planetology and solar system exploration. It should also help to influence the planning of scientific strategies for the encounter of the Rosetta spacecraft with Comet Churyumov-Gerasimenko.

Divided into two parts, the first four chapters of Comets and their Origin refer to comets and their formation in general, describing cometary missions, comet remote observations, astrochemistry, artificial comets, and the chirality phenomenon. The second part covers the cometary ROSETTA mission, its launch, journey, scientific objectives, and instrumentations, as well as the landing scenario on a cometary nucleus. Along the way, the author presents general questions concerning the origin of terrestrial water and the molecular beginnings of life on Earth, as well as how the instruments used on a space mission like ROSETTA can help answer them. The text concludes with a chapter on what scientists expect from the ROSETTA mission and how its data will influence our life on Earth. As a result, the author elucidates highly topical and fascinating knowledge to scientists and students of various scientific backgrounds, allowing them to work with ROSETTA's data.

Volume 68 of Reviews in Mineralogy and Geochemistry reviews Oxygen in the Solar System, an element that is so critically important in so many ways to planetary science. The book is based on three open workshops: Oxygen in the Terrestrial Planets, held in Santa Fe, NM July 20-23, 2004; Oxygen in Asteroids and Meteorites, held in Flagstaff, AZ June 2-3, 2005; and Oxygen in Earliest Solar System Materials and Processes (and including the outer planets and comets), held in Gatlinburg, TN September 19-22, 2005. As a consequence of the cross-cutting approach, the final book spans a wide range of fields relating to oxygen, from the stellar nucleosynthesis of oxygen, to its occurrence in the interstellar medium, to the oxidation and isotopic record preserved in 4.56 Ga grains formed at the Solar System's birth, to its abundance and speciation in planets large and small, to its role in the petrologic and physical evolution of the terrestrial planets. Contents: Introduction Oxygen isotopes in the early Solar System - A historical perspective Abundance, notation, and fractionation of light stable isotopes Nucleosynthesis and chemical evolution of oxygen Oxygen in the interstellar medium Oxygen in the Sun Redox conditions in the solar nebula: observational, experimental, and theoretical constraints Oxygen isotopes of chondritic components Mass-independent oxygen isotope variation in the solar nebula Oxygen and other volatiles in the giant planets and their satellites Oxygen in comets and interplanetary dust particles Oxygen and asteroids Oxygen isotopes in asteroidal materials Oxygen isotopic composition and chemical correlations in meteorites and the terrestrial planets Record of low-temperature alteration in asteroids The oxygen cycle of the terrestrial planets: insights into the processing and history of oxygen in surface environments Redox conditions on small bodies, the Moon and Mars Terrestrial oxygen isotope variations and their implications for planetary lithospheres Basalts as probes of planetary interior redox state Rheological consequences of redox state

Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and planetary science and considers its potential relevance to the origins of life on Earth and elsewhere. Guided by the review papers in this book, the concluding chapter aims to identify key questions to motivate future research and stimulate astrobiological applications of current and future research facilities and space missions. Today’s rich array of new spacecraft, telescopes and dedicated scientists promises a steady flow of discoveries and insights that will ultimately lead us to the answers we seek.

The Transactions XXVIIA Reports on Astronomy 2006-2009 provides a comprehensive and authoritative review of what has been achieved in astronomy during the years 2006 to 2009. These insightful and up-to-date reviews have been written by the presidents and chairpersons of the IAU scientific bodies: the Divisions, the Commissions, and the Working Groups. Topics covered in this wide-ranging volume include: fundamental astronomy; the Sun and heliosphere; planetary sciences; stars; variable stars; interstellar matter; the Galactic system; galaxies and the Universe; optical and infrared techniques; radio astronomy; space and high-energy astrophysics; and other IAU activities. The reviews have been written at a level suitable for colleagues in the same fields, but will also be useful for students and researchers wishing to gain an overview of astronomical fields beyond their own research area.
