This book implements several outstanding features which are helpful to the general reader. It is organized in the form of a ‘Questions and Answers’ guide, an approach unique in the field of astrobiology. The questions and answers are linked in a conversation-like style, with each new question following from the previous answer. The book is organized into 20 chapters discussing broad and comprehensive topics, with over 250 questions answered. While the book is written for general readers who are assumed to have an interest in science, though not necessarily an extensive background, it will also be helpful to the beginning student and those who wish to pursue further one or more aspects of the field. It provides the reader with a comprehensive set of ‘Further Readings.’ After each chapter, resource material is keyed to the individual answers to each question. At the end of the book, full references are given, as well as a guide for how to obtain them. A thorough Index is also provided. The streamlined, condensed, and yet comprehensive approach provided here is well-suited for stimulating the appetite of many readers for delving more into the fascinating and multi-faceted field of astrobiology.

Life is a property of the universe. We may not know how it began or where else it exists, but we have come to know a great deal about how it relates to stars, planets, and the larger cosmos. In clear and compelling terms, this book shows how the emerging field of astrobiology investigates the nature of life in space. How did life begin? How common is it? Where do we fit in? These are the important questions that astrobiology seeks to answer. A truly interdisciplinary endeavor, astrobiology looks at the evidence of astronomy, biology, physics, chemistry, and a host of other fields. A grand narrative emerges, beginning from the smallest, most common particles yet producing amazing complexity and order. Lucas Mix is a congenial guide through the depths of astrobiology, exploring how the presence of planets around other stars affects our knowledge of our own; how water, carbon, and electrons interact to form life as we know it; and how the processes of evolution and entropy act upon every living thing. This book also reveals that our understanding and our context are deeply intertwined. It shows how much astrobiology can tell us about who we are—as a planet, as a species, and as individuals.

This work is aimed at the upper-level astrobiology course and places a strong emphasis on the astronomy perspective.

Astrobiology is an expanding, interdisciplinary field investigating the origin, evolution and future of life in the universe. Tackling many of the foundational debates of the subject, from discussions of cosmological evolution to detailed reviews of common concepts such as the 'Rare Earth' hypothesis, this volume is the first systematic survey of the philosophical aspects and conundrums in the study of cosmic life. The author's exploration of the increasing number of cross-over problems highlights the relationship between astrobiology and cosmology and presents some of the challenges of multidisciplinary study. Modern physical theories dealing with the multiverse add a further dimension to the debate. With a selection of beautifully presented illustrations and a strong emphasis on constructing a unified methodology across disciplines, this book will appeal to graduate students and specialists who seek to rectify the fragmented nature of current astrobiological endeavour, as well as curious astrophysicists, biologists and SETI enthusiasts.

Compelling account of how ideas of alien life have evolved for general readers, amateur astronomers and undergraduate students studying astrobiology.

Astrobiology, the study of life and its existence in the universe, is one of the hottest areas of scientific research. Lewis Dartnell considers some of the fascinating questions facing researchers today. Could life exist anywhere else in the universe? What might aliens really look like? Dartnell explains why Earth is uniquely suited for life and reveals our profound connection to the cosmos.

Examines the origins of life on Earth and the search for extraterrestrial life, through an understanding of the factors that have allowed life to exist on this planet and the commonalities on others that may enable life elsewhere.
