Every rock has a story tell, and none more so than those which have fallen from the sky: meteorites. Originating in the Asteroid Belt between Mars and Jupiter, these rocky fragments offer clues not just to the earliest origins of the Solar System but also to Earth's very survival into the future.Sky at Night presenter, Dr Tim Gregory takes us on a journey through the very earliest days of our Solar System to the spectacular meteorite falls that produced 'fiery rain' in 1792, to the pre-solar grains (literally stardust) that were blown in from other solar systems and are the oldest solid objects ever discovered on earth.Meteorites reveal a story much bigger than ourselves or our planet. As Tim says, 'it is an epic beyond compare'.

This definitive guide provides advanced students and researchers with a detailed yet accessible overview of all of the central topics of meteor science. Leading figures from the field summarise their active research on themes ranging from the physical composition of meteoroids to the most recent optical and radar observations and ongoing theoretical developments. Crucial practical issues are also considered, such as the risk posed by meteoroids - to spacecraft, and on the ground - and future avenues of research are explored. Taking advantage of the latest dynamical models, insights are offered into meteor flight phenomena and the evolution of meteoroid streams and complexes, as well as describing the in-depth laboratory analysis of recovered material. The rapid rate of progress in twenty-first-century research makes this volume essential reading for anyone who wishes to understand how recent developments broaden our understanding of meteors, meteoroids and their origins.

Meteorite research is fundamental to our understanding of the origin and early history of the Solar System. Some meteorites were produced by melting on asteroids, a few are from the Moon and others are martian. Their study yields a chronology of the first 100 million years of Solar System history, and provides evidence that our Sun went through a highly radiative, T Tauri stage. This book considers the mechanism and timing of core formation and basaltic volcanism on asteroids, and the effects of heating water-rich bodies. Results from meteorite research are placed in a galactic setting, and a theory is proposed for the origin of the planets of our Solar System. This advanced yet succinct introduction provides a classification of meteorites, and discusses their ages and origin. It will be valuable to graduate students and scientists in astrophysics, space research, cosmochemistry, geochemistry, isotope geology, and earth and planetary sciences.

Meteorites are fascinating cosmic visitors. Using accessible language, this book documents the history of mineralogy and meteorite research, summarizes the mineralogical characteristics of the myriad varieties of meteorites, and explains the mineralogical characteristics of Solar System bodies visited by spacecraft. Some of these bodies contain minerals that do not occur naturally on Earth or in meteorites. The book explains how to recognize different phases under the microscope and in backscattered electron images. It summarizes the major ways in which meteoritic minerals form - from condensation in the expanding atmospheres of dying stars to crystallization in deep-seated magmas, from flash melting in the solar nebula to weathering in the terrestrial environment. Containing spectacular backscattered electron images, color photographs of meteorite minerals, and with an accompanying online list of meteorite minerals, this book provides a useful resource for meteorite researchers, terrestrial mineralogists, cosmochemists, and planetary scientists, as well as graduate students in these fields. Alan Rubin is a meteorite researcher who recently retired from the University of California, where he worked as a research geochemist. He is a fellow of the Meteoritical Society and winner of the Nininger Meteorite Award and seven Griffith Observer science writing awards. He is the namesake of the garnet mineral rubinite and the main-belt asteroid 6227Alanrubin. He is the author of 200 research papers and 50 popular science articles. He is also the author of Disturbing the Solar System (Princeton, 2004). Chi Ma is a mineralogist at the California Institute of Technology, with research interests in nanomineralogy and the discovery of new minerals, especially those representing extreme conditions of formation. He has discovered and led investigations on 45 new minerals, including 14 refractory minerals from the solar nebula and 11 high-pressure minerals. He is a fellow of the Mineralogical Society of America. The oxide mineral machiite was named in his honor.
