Energy, chemistry, solvents, and habitats - the basic elements of living systems - define the opportunities and limitations for life on other worlds. This class-tested text examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, exotic forms of life that would not have to rely on carbon as basic chemical element, solar energy as a main energy source, or water as primary solvent. Finally the question of detecting bio- and geosignature of such life forms is discussed, ranging from Earth environments to deep space. While speculative considerations in this emerging field of science cannot be avoided, the authors have tried to present their study with the breadth and seriousness that a scientific approach to this issue requires. They seek an operational definition of life and investigate the realm of possibilities that nature offers to realize this very special state of matter and avoid scientific jargon wherever possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers.
The second edition thoroughly updates this text in view of the rapid progress in the field and a substantial amount of new material has been added, in particular sections and chapters on adaptation to extreme environments, the future and fate of living systems, life detection concepts based on the thorough analysis of the Viking missions and the issue around the meteorite ALH 84001, and - last but not least - recommendations for the optimization of future space exploration missions. |

In six years, Galileo Galilei went from being a mathematics professor to a star in the court of Florence to a target of the Inquisition. And during that time, Galileo made a series of astronomical discoveries that reshaped the ideas of the physical nature of the heavens and transformed him from a university mathematician into a court philosopher.
Galileo's Instruments of Credit proposes radical new interpretations of key episodes of Galileo's career, including his telescopic discoveries of 1610, the dispute over sunspots, and the conflict with the Holy Office over the relationship between Copernicanism and Scripture. Galileo's tactics shifted as rapidly as his circumstances, argues Mario Biagioli, and these changes forced him to respond swiftly to the opportunities and risks posed by unforeseen inventions, other discoveries, and his opponents.
Focusing on the aspects of Galileo's scientific life that extended beyond court culture and patronage, Biagioli offers a revisionist account of the different systems of exchanges, communication, and credibility at work in Galileo's career. Galileo's Instruments of Credit will fascinate readers interested in the history of astronomy and the history of science in general. |

There are many planetary systems other than our own, but it is only through a detailed understanding of the relatively accessible bodies in our solar system that a thorough appreciation of planetary science can be gained. This is particularly pertinent with the recent discovery of extra-solar planets and the desire to understand their formation and the prospect of life on other worlds.

The field of space and astronomy is devoted to the study of the heavenly bodies, their behavior, and characteristics. As the oldest natural science, knowledge of astronomy has come from some of the world's greatest scientists, including Copernicus, Galileo, Kepler, Newton, and Einstein. Astronomy experiments are not only historically important, but they also provide knowledge of basic scientific principles, such as how early thinkers disproved the notion that Earth is the center of the solar system. Modern astronomy relies on technology that has been invented in the last few decades, and current research includes space travel, satellites, and telescopes that interpret radiation from all parts of the electromagnetic spectrum. "Space and Astronomy Experiments" provides teachers with 20 new and original experiments that help students learn basic scientific principles and important skills. Presenting experiments from all areas, including physics and geology, the text contains proven classroom experiments that broaden understanding of both science facts and the nature of space and astronomy. Full-color line illustrations, tables, and charts round out this comprehensive resource. |

This book describes the phenomena of cyclic activity as they are observed in the Sun and solar-type stars. Although there are many books currently available on the Sun, solar activity, and activity phenomena in stars, this is the only one that links these topics and attempts to define stellar parameters that are conducive to activity in general and cyclic activity in particular and to descibe the mechanisms responsible for the various modes of activity. The first seven chapters review our basic knowledge of the Sun, of the solar activity cycle, and of stellar activity cycles. Chapter 1 also describes some of the terrestrial effects of solar activity and stresses the importance of reliable predictions of the parameters of future cycles. Chapters 8 through 13 describe some of the latest research into the solar cycle, including extended activity cycle and the polar fields reversal. The latest contributions from studies of dynamo theory, of helioseismology, and of chaos theory are also covered. The last chapter discusses the methods currently in use to predict parameters of future cycles and their success (or failure) for the maximum of cycle 22. |

This book features essential coverage of all major aspects of Earth's solar system, from every feature of the major planets to their satellites, small bodies, interplanetary phenomena, and cosmological context. Designed to meet the needs of both general readers and students, this completely revised and updated edition covers 180 major topics on Earth's solar system as it is understood from the latest perspectives. For this new edition, 58 new topics have been added and every essay has been thoroughly expanded, from the text through bibliographies, to bring it up to date in view of the many interplanetary missions that have expanded our knowledge of the solar system - from Pioneer and Voyager through the missions of Galileo, Cassini-Huygens, the Hubble Space Telescope, and the latest Mars probes as of 2009. Scope and coverage: No reference dedicated to the solar system is this detailed or complete and up to date. Coverage is presented in an A-Z format - from 'Archaeoastronomy' and 'Asteroids' through 'Venus' Volcanoes' and 'White and Black Dwarfs' - and is supplemented by more than two hundred photos. For those wishing instant access to essays grouped by planetary system, a Category Index appears in the front of every volume. Essays fall into one or more of the following categories: the Cosmological Context, Earth, the Jovian System, Life in the Solar System, Mars, Mercury, Natural Planetary Satellites, Neptune, Planets and Planetology, the Saturnian System, Scientific Methods, Small Bodies, the Solar System as a Whole, the Stellar Context, the Sun, Uranus, and Venus. Organization and format: Essays range in length from three to seven pages and offer a complete overview of the topic as well as an assessment of knowledge gained, methods of study, or applications. Each essay begins with standard, ready-reference information, including the title of the essay, the category (or categories) in which the essay falls, and a summary of the importance of the topic and the current state of our knowledge. The essay is then broken down into several subsections. An 'Overview' section, generally the longest subsection in the essay, details basic information about the subject and discusses the main facts about the topic. 'Knowledge Gained/Methods of Study/Applications' details how the topic is investigated, what scientific knowledge we have accumulated, or the uses of the knowledge we have gained. 'Context' addresses the topic from the larger perspective of the history of solar-system science and its relevance for humankind. 'Further Reading' is an annotated selection of the most important print resources for further study. Lastly, 'See Also' lists cross-references to other essays in The Solar System covering related topics. Special features: the front matter of each volume includes a Complete List of Contents and a Category Index. The set is heavily illustrated, with over 300 photos. At the end of volume three, users will find a general bibliography, a list of web resources, a comprehensive glossary, and a full subject index. This title contains 3 Volumes; 1,056 Pages; 180 Essays, 58 New; 'See Also' Cross-References; Complete List of Contents; Category Index; Glossary; Bibliography; Web Sites; and Subject Index.

The spectacular collision of Comet Shoemaker-Levy 9 with Jupiter in July 1994 was a unique event in the history of astronomy. With a year's advance warning, astronomers and planetary scientists around the world were able to coordinate an observing campaign to track the event in unprecedented detail. A year after the event, a workshop at the Space Telescope Science Institute provided the first opportunity for them to bring together their observations and foster a new understanding of the impact. In this book, the editors present fifteen invited reviews from authors selected as international leaders in the study of the impact and its aftermath. They have edited and arranged the chapters to provide a thorough and comprehensive overview of our knowledge of the event. While our understanding of the impact will evolve with future work, this book provides a solid foundation for new insights. |
