This book is the first to provide a comprehensive, readily understandable report on the European Space Agency’s Gaia mission that will meet the needs of a general audience. It takes the reader on an exciting journey of discovery, explaining how such a scientific satellite is made, presenting the scientific results available from Gaia to date, and examining how the collected data will be used and their likely scientific consequences. The Gaia mission will provide a complete and high-precision map of the positions, distances, and motions of the stars in our galaxy. It will revolutionize our knowledge on the origin and evolution of the Milky Way, on the effects of mysterious dark matter, and on the birth and evolution of stars and extrasolar planets. The Gaia satellite was launched in December 2013 and has a foreseen operational lifetime of five to six years, culminating in a final stellar catalogue in the early 2020s. This book will appeal to all who have an interest in the mission and the profound impact that it will have on astronomy.

Gaia, in which James Lovelock puts forward his inspirational and controversial idea that the Earth functions as a single organism, with life influencing planetary processes to form a self-regulating system aiding its own survival, is now a classic work that continues to provoke heated scientific debate.

The emergence of modern sciences in the seventeenth century profoundly renewed our understanding of nature. For the last three centuries new ideas of nature have been continually developed by theology, politics, economics, and science, especially the sciences of the material world. The situation is even more unstable today, now that we have entered an ecological mutation of unprecedented scale. Some call it the Anthropocene, but it is best described as a new climatic regime. And a new regime it certainly is, since the many unexpected connections between human activity and the natural world oblige every one of us to reopen the earlier notions of nature and redistribute what had been packed inside. So the question now arises: what will replace the old ways of looking at nature? This book explores a potential candidate proposed by James Lovelock when he chose the name 'Gaia' for the fragile, complex system through which living phenomena modify the Earth. The fact that he was immediately misunderstood proves simply that his readers have tried to fit this new notion into an older frame, transforming Gaia into a single organism, a kind of giant thermostat, some sort of New Age goddess, or even divine Providence. In this series of lectures on 'natural religion,' Bruno Latour argues that the complex and ambiguous figure of Gaia offers, on the contrary, an ideal way to disentangle the ethical, political, theological, and scientific aspects of the now obsolete notion of nature. He lays the groundwork for a future collaboration among scientists, theologians, activists, and artists as they, and we, begin to adjust to the new climatic regime.

Gregory Bateson (1904–1980), anthropologist, psychologist, systems thinker, student of animal communication, and insightful environmentalist, was one of the most important holistic thinkers of the twentieth century. Noel G. Charlton offers this first truly accessible introduction to Bateson's work, distilling and clarifying Bateson's understanding of the "mind" or "mental systems" as being present throughout the living Earth, in systems and creatures of all kinds. Part biography, part overview of the evolution of his ideas, Charlton's book situates Bateson's thought in relation to that of other ecological thinkers. This long-awaited volume opens up this challenging thinker's body of work and introduces it to a new generation of readers.

This classic work is reissued with a new preface by the author. Written for non-scientists the idea is put forward that life on Earth functions as a single organism.

A critical examination of James Lovelock's controversial Gaia hypothesis One of the enduring questions about our planet is how it has remained continuously habitable over vast stretches of geological time despite the fact that its atmosphere and climate are potentially unstable. James Lovelock's Gaia hypothesis posits that life itself has intervened in the regulation of the planetary environment in order to keep it stable and favorable for life. First proposed in the 1970s, Lovelock's hypothesis remains highly controversial and continues to provoke fierce debate. On Gaia undertakes the first in-depth investigation of the arguments put forward by Lovelock and others—and concludes that the evidence doesn't stack up in support of Gaia. Toby Tyrrell draws on the latest findings in fields as diverse as climate science, oceanography, atmospheric science, geology, ecology, and evolutionary biology. He takes readers to obscure corners of the natural world, from southern Africa where ancient rocks reveal that icebergs were once present near the equator, to mimics of cleaner fish on Indonesian reefs, to blind fish deep in Mexican caves. Tyrrell weaves these and many other intriguing observations into a comprehensive analysis of the major assertions and lines of argument underpinning Gaia, and finds that it is not a credible picture of how life and Earth interact. On Gaia reflects on the scientific evidence indicating that life and environment mutually affect each other, and proposes that feedbacks on Earth do not provide robust protection against the environment becoming uninhabitable—or against poor stewardship by us.
