Encyclopedia of the Solar System, Second Edition

Long before Galileo published his discoveries about Jupiter, lunar craters, and the Milky Way in the Starry Messenger in 1610, people were fascinated with the planets and stars around them. That interest continues today, and scientists are making new discoveries at an astounding rate. Ancient lake beds on Mars, robotic spacecraft missions, and new definitions of planets now dominate the news. How can you take it all in? Start with the new Encyclopedia of the Solar System, Second Edition.This self-contained reference follows the trail blazed by the bestselling first edition. It provides a framework for understanding the origin and evolution of the solar system, historical discoveries, and details about planetary bodies and how they interact―and has jumped light years ahead in terms of new information and visual impact. Offering more than 50% new material, the Encyclopedia includes the latest explorations and observations, hundreds of new color digital images and illustrations, and more than 1,000 pages. It stands alone as the definitive work in this field, and will serve as a modern messenger of scientific discovery and provide a look into the future of our solar system.

· Forty-seven chapters from 75+ eminent authors review fundamental topics as well as new models, theories, and discussions· Each entry is detailed and scientifically rigorous, yet accessible to undergraduate students and amateur astronomers· More than 700 full-color digital images and diagrams from current space missions and observatories amplify the chapters· Thematic chapters provide up-to-date coverage, including a discussion on the new International Astronomical Union (IAU) vote on the definition of a planet· Information is easily accessible with numerous cross-references and a full glossary and index

Lucy McFadden is a planetary scientist at the University of Maryland. She was the founding director of the College Park Scholars Program, Science, Discovery and the Universe. She has published over 75 articles in refereed journals and has been co-investigator on NASA’s NEAR, Deep Impact and Dawn missions exploring asteroids and comets. She has served on committees on solar system exploration for the National Academy of Sciences, and on the editorial board of Icarus.

Torrence V. Johnson is a specialist on icy satellites in the solar system. He has written over 130 publications for scientific journals. He received a Ph.D. in planetary science from the California Institute of Technology and is now the Chief Scientist for Solar System Exploration at the Jet Propulsion Laboratory. He was the Project Scientist for the Galileo mission and is currently an investigator on the Cassini mission. He is the recipient of two NASA Exceptional Scientific Achievement Medals and the NASA Outstanding Leadership Medal and has an honorary doctorate from the University of Padua, where Galileo made his first observations of the solar system.

Paul R. Weissman is a Senior Research Scientist at JPL, specializing in comets. He is the author of over 100 scientific papers and 30 popular articles. He is also the co-author, with Alan Harris, of a children’s book on the Voyager mission. Dr. Weissman received his doctorate in planetary and space physics from the University of California, Los Angeles. His work includes both theoretical and observational studies of comets, investigating their orbital motion, their physical make-up, and the threat they pose due to possible impacts on the Earth. Dr. Weissman is an Interdisciplinary Scientist on ESA’s Rosetta mission to comet Churyumov-Gerasimenko.
