PDF-(BOOK)-Meteorites

Over 500 color images and engaging text provide insight into these interesting collectibles from out of this world Meteorites link back to the early stages of the Milky Way galaxy and are the oldest items one can touch some dating back to before the creation of our solar system Meteorites are also among the most primitive forms of matter you can closely observe and handle Some of these ambassadors from the void were created in stars that no longer exist Others provide the curious researcher with original material from the earliest days of our own solar system These rocks tell tales to those who know how to read them of nebulas novas supernovas red giants and impacting celestial bodies Readers can explore metallic stonyiron and stony meteorites meteorite falls Northwest African meteorites and rare meteorites.

Plate tectonics starts. 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. A well-illustrated overview of the science and (literal) impact of these space rocks. -- Science News, on the first editionLeading experts in the field provide a compelling introduction to the space rocks that enter Earth\'s atmosphere at speeds ranging from 25,000 mph to 160,000 mph. Scientists estimate that about 48.5 tons of meteoritic material falls on the Earth each day. These messengers from space give us a unique insight into the nature of the material that was present when our solar system formed.Many of the specimen meteorites in this second edition were re-photographed to improve quality, and the optical microscopy shots were updated. There is also much new information on discoveries and developments in the study of meteorites, including:Meteorite falls and craters, and new information on ones previously covered Use of weather radar to detect and analyze meteorites, such as the 28,000 mph January 18, 2018, Michigan fireball How astrophysicists determine if a meteorite comes from Mars, and information about the Martian meteorites found to date Updated information on the results of the European Space Agency\'s Rosetta Mission in which a controlled impact was successfully completed into Comet 67P after investigating it with a probe for more than two years.Co-author Sara Russell, who is part of NASA\'s Mars program, provides the latest news about NASA\'s Mars programs, including the Mars Rover, which landed in 2016. The authors trace the formation and breakup of the planets, asteroids, and comets where meteorites originated, their long journey through space, their fall to Earth, their recovery, and what scientists are learning from them. The book contains a great deal of material about the “84001 Martian meteorite,” which has raised provocative new questions about life on the red planet. Looking forward, the authors chart the exciting new era of planetary, asteroidal, and cometary exploration planned for this century. In recent years, meteorites have caught the imagination of scientist and collector alike. An army of people are now actively searching for them in the hot and cold deserts of Earth. Fascinating extraterrestrial rocks in meteorites are our only contact with materials from beyond the Earth-Moon system. Using well known petrologic techniques, O. Richard Norton reveals in vivid color their extraordinary external and internal structures and taking readers to the atomic level, describes the environment within the solar nebula that existed before the planets accreted. Extensively illustrated, this volume is a valuable guide to assist searchers in the field in recognizing the many classes of meteorites and it is a superb reference source for students, teachers and scientists who wish to probe deeper these amazing rocks from space. O. Richard Norton is a contributing editor for Meteorite magazine and the author of The Planetarium and Atmospherium and Rocks from Space (Mountain Press, 1998). For the last 40 years, he has taught astronomy and space sciences at various US institutions. A complete visual reference for meteorite classification, this atlas combines high resolution optical microscope images with detailed descriptions. It provides a systematic account of meteorites and their most important classification parameters, making it an essential resource for meteorite researchers. Each chapter starts with a description of the meteorite class, with a summary of the mineralogical, chemical and isotopic characteristics of the group. The full-color images are taken in plane- and cross-polarized light and reflected light, and arranged to highlight textural variations in meteorites. Specimens are grouped to show the effects of increasing thermal alteration and shock, as well as variations in chondrule size and type. Chapters on iron meteorites, pallasites and mesosiderites are included, photographed as mounts in reflected light, to show the range of textural variations that accompany these meteorites.
