Astrobiology is a rapidly emerging field of intense scientific and technological activity, evident from the numerous recent space probes attempting to look for the possible existence of alien primeval life. This book explores the possibility of life on other planets and moons and exoplanets, either in their parent stars’ habitable zones or as free-floating exoplanets. The wide range of topics discussed here include environments influencing the origin and evolution of life and cosmological effects, such as the implications of a dark energy-dominated universe for astrobiology. Astrobiology is a highly interdisciplinary subject involving astronomy, physics, biology, geology, and chemistry, in addition to being a technology-intensive discipline. This book highlights the various methods used to detect possible advanced alien technology combining all these areas.

Astrobiology is a very broad interdisciplinary field covering the origin, evolution, distribution, and destiny of life in the universe, as well as the design and implementation of missions for solar system exploration. A review covering its complete spectrum has been missing at a level accessible even to the non-specialist. The last section of the book consists of a supplement, including a glossary, notes, and tables, which represent highly condensed `windows' into research ranging from basic sciences to earth and life sciences, as well as the humanities. These additions should make The New Science of Astrobiology accessible to a wide readership: scientists, humanists, and the general reader will have an opportunity to participate in one of the most rewarding activities of contemporary culture.

"This book presents the current trends of research in exoplanets, with an aim to understand the big question: "are we alone in the universe?". This gives us the insight towards the fascinating extreme habitable worlds in which specific extremophiles potentially could survive. The content briefly describes the similarity indexing techniques such as: Earth Similarity Index (ESI) to find Earth-like exoplanets, Mars Similarity Index (MSI) to find Mars-like exoplanets, and also indexing applied for specific water extremophile (i.e. Tardigrades) to potentially survive on exoplanets. These tardigrades are indexed as Active Tardigrade Index (ATI) and Cryptobiotic Tardigrade Index (CTI). Basically the book is a bridge between astronomy, astrophysics and current astrobiology studies"--

Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and planetary science and considers its potential relevance to the origins of life on Earth and elsewhere. Guided by the review papers in this book, the concluding chapter aims to identify key questions to motivate future research and stimulate astrobiological applications of current and future research facilities and space missions. Today’s rich array of new spacecraft, telescopes and dedicated scientists promises a steady flow of discoveries and insights that will ultimately lead us to the answers we seek.

Are we alone in the universe? How did life arise on our planet? How do we search for life beyond Earth? These profound questions excite and intrigue broad cross sections of science and society. Answering these questions is the province of the emerging, strongly interdisciplinary field of astrobiology. Life is inextricably tied to the formation, chemistry, and evolution of its host world, and multidisciplinary studies of solar system worlds can provide key insights into processes that govern planetary habitability, informing the search for life in our solar system and beyond. Planetary Astrobiology brings together current knowledge across astronomy, biology, geology, physics, chemistry, and related fields, and considers the synergies between studies of solar systems and exoplanets to identify the path needed to advance the exploration of these profound questions. Planetary Astrobiology represents the combined efforts of more than seventy-five international experts consolidated into twenty chapters and provides an accessible, interdisciplinary gateway for new students and seasoned researchers who wish to learn more about this expanding field. Readers are brought to the frontiers of knowledge in astrobiology via results from the exploration of our own solar system and exoplanetary systems. The overarching goal of Planetary Astrobiology is to enhance and broaden the development of an interdisciplinary approach across the astrobiology, planetary science, and exoplanet communities, enabling a new era of comparative planetology that encompasses conditions and processes for the emergence, evolution, and detection of life.

Informed by new planetary discoveries and the findings from recent robotic missions to Mars, Jupiter, and Saturn, scientists are rapidly replacing centuries of speculation about potential extraterrestrial habitats with real knowledge about the possibility of life outside our own biosphere -- if it exists, and where. This second edition of Kevin W. Plaxco and Michael Gross's widely acclaimed text incorporates the latest research in astrobiology to bring readers the most comprehensive, up-to-date, and engaging introduction to the field available. Plaxco and Gross expand their examination of the origin of chemical elements, the developments that made the Universe habitable, and how life continues to be sustained. They discuss in great detail the formation of the first galaxies and stars, the diverse chemistry of the primordial planet, the origins of metabolism, the evolution of complex organisms, and the feedback regulation of Earth's climate. They also explore life in extreme habitats, potential extraterrestrial habitats, and the current status of the search for extraterrestrial life. Weaving together the relevant threads of astronomy, geology, chemistry, biophysics, and microbiology, this broadly accessible introductory text captures the excitement, controversy, and progress of the dynamic young field of astrobiology. New to this edition is a glossary of terms and an epilogue recapping the key unanswered questions, making Astrobiology an ideal primer for students and, indeed, for anyone curious about life and the Universe. Praise for the first edition of Astrobiology "Certainly the most readable introduction to astrobiology now available." -- Chemical and Engineering News "Plaxco and Gross bring us as close to aliens as we can currently get. I recommend this book to anyone interested in science's newest kid on the block." -- Astronomy Now "A good read for all those who are fascinated by the search for extraterrestrial life and the origin of life on our own planet. I shall certainly value it in my own library." -- Chemistry World "An accessible guide to this young and interdisciplinary field." -- Physics World "The fascinating world of extremophiles is well presented, and a broad overview of the searches for evidence of life beyond Earth rounds off the book. The text is liberally illustrated with relevant figures that greatly enhance the content, and entertaining snippets of information detailing the quirks of research in this field nicely supplement the scientific content." -- Astrobiology "A comprehensive yet concise introduction to the field." -- The Space Review

Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. This book offers an analysis undertaken from the perspective of science education, to discuss the nature of the particular challenges faced by those seeking to facilitate public education in the field of astrobiology. The authors also address the question of the formation of a protocell and its function at the system level. It will further deal with the environmental pressures likely present on the early Earth, as they would have influenced the lifetime of unstable or reactive components needed for the start of life. In addition, the method of the transition from prebiotic organic microsystems to the primordial communities of prokaryotes is explored. The authors also explain some aspects related to aqueous interfacial processes in the context of prebiotic chemistry under the point of view of our current experimental results. Moreover, there is considerable interest in astrobiology in investigating icy worlds and the microbial forms that thrive in extreme environments, especially under those cold conditions that can provide a model for some extraterrestrial environments. This book reviews the general trends concerning the biodiversity and ecology of psychrophilic microorganisms and their molecular mechanisms of adaptation and evolution, as well as summarise the latest results on this topic in samples from icy environments. Other chapters summarise the morphological signatures of flowing water, the astrobiological potential of the dunes, and the theoretical modelling background of the presence of liquid water on Mars today.

The past decade has seen a remarkable revolution in genomic research, the discoveries of extreme environments in which organisms can live and even flourish on Earth, the identification of past and possibly present liquid-water environments in our solar system, and the detection of planets around other stars. Together these accomplishments bring us much closer to understanding the origin of life, its evolution and diversification on Earth, and its occurrence and distribution in the cosmos. A new multidisciplinary program called Astrobiology was initiated in 1997 by the National Aeronautics and Space Administration (NASA) to foster such research and to make available additional resources for individual and consortium-based efforts. Other agencies have also begun new programs to address the origin, evolution, and cosmic distribution of life. Five years into the Astrobiology program, it is appropriate to assess the scientific and programmatic impacts of these initiatives. Edward J. Weiler, NASA's associate administrator for the Office of Space Science, tasked the Committee on the Origins and Evolution of Life (COEL) with assessing the state of NASA's Astrobiology program.
