Life in the Cosmos by Manasvi Lingam,Avi Loeb Pdf

A rigorous and scientific analysis of the myriad possibilities of life beyond our planet. “Are we alone in the universe?” This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life. Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Avi Loeb tackle three areas of interest in hunting for life “out there”: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see. Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.

Strategies for the Search for Life in the Universe by M.D. Papagiannis Pdf

Leo Goldberg Kitt Peak National Observatory Tucson, Arizona 85726, U. S. A. Of all the reasons for exploring the Universe, none is more com pelling than the possibility of discovering intelligent life elsewhere in the Universe. Still the quest for extraterrestrial life has been near the bottom of the astronomers' list of priorities, not because the number of extraterrestrial civilizations is conjectured to be van ishingly small, but because our powers of detection were thought to be far too weak. About ten years ago, however, the growing reach of ra dio telescopes on the ground and of optical and infrared telescopes in space persuaded a number of thoughtful astronomers that the time for a more serious search had arrived. Accordingly, a joint Soviet-American conference on the problems of Communication with Extraterrestrial In telligence was convened at the Byurakan Astrophysical Observatory of the Armenian Academy of Sciences during September 5-11, 1971 and was soon followed by a number of other important meetings, notably a series of NASA-sponsored workshops in the USA held between January, 1975 and May, 1976. Since SETI is fundamentally an international undertaking and as tronomical methods and techniques are required for its pursuit, it is natural for the International Astronomical Union to lend its support by sponsoring conferences and otherwise facilitating cooperation among countries. The active involvement of the I. A. U.

The Eerie Silence by Paul Davies Pdf

One of the world’s leading scientists explains why—and how—the search for intelligent life beyond Earth should be expanded. Fifty years ago, a young astronomer named Frank Drake first pointed a radio telescope at nearby stars in the hope of picking up a signal from an alien civilization. Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). After a half-century of scanning the skies, however, astronomers have little to report but an eerie silence—eerie because many scientists are convinced that the universe is teeming with life. Physicist and astrobiologist Paul Davies has been closely involved with SETI for three decades and chairs the SETI Post-Detection Taskgroup, charged with deciding what to do if we’re suddenly confronted with evidence of alien intelligence. He believes the search so far has fallen into an anthropocentric trap—assuming that an alien species will look, think, and behave much like us. In this provocative book Davies refocuses the search, challenging existing ideas of what form an alien intelligence might take, how it might try to communicate with us, and how we should respond if it does.

Alien Oceans by Kevin Hand Pdf

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

Pathways to the Origin and Evolution of Meanings in the Universe by Alexei A. Sharov,George E. Mikhailovsky Pdf

Pathways to the Origin and Evolition of Meanings in the Universe The book explains why meaning is a part of the universe populated by life, and how organisms generate meanings and then use them for creative transformation of the environment and themselves. This book focuses on interdisciplinary research at the intersection of biology, semiotics, philosophy, ethology, information theory, and the theory of evolution. Such a broad approach provides a rich context for the study of organisms and other semiotic agents in their environments. This methodology can be applied to robotics and artificial intelligence for developing robust, adaptable learning devices. In this book, leading interdisciplinary scholars reveal their vision on how to integrate natural sciences with semiotics, a theory of meaning-making and signification. Developments in biology indicate that the capacity to create and understand signs is not limited to humans or vertebrate animals, but exists in all living organisms - the fact that inspired the integration of biology and semiotics into biosemiotics. The authors discuss the nature of semiotic agents (organisms and other autonomous goal-directed units), meaning, signs, information, memory, evolution, and consciousness. Also discussed are issues including the origin of life, potential meaning and its actualization, top-down causality in physics and biology, capacity of organisms to encode their functions, the strategy of organisms to combine homeostasis with direct adaptation to new life-cycle phases or new environments, multi-level memory systems, increase of freedom via enabling constraints, creative modeling in evolution and learning, communication in animals and humans, the origin and function of language, and the distribution and transfer of life in space. This is the first book on biosemiotics in its global conceptual and spatial scope. Biosemiotics is presented using the language of natural sciences, which supports the scientific grounding of semiotic terms. Finally, the cosmic dimension of life and meaning-making leads to a reconsideration of ethical principles and ecological mentality here on earth and in space exploration. Audience Theoretical biologists, ethologists, astrobiologists, ecologists, evolutionary biologists, philosophers, phenomenologists, semioticians, biosemioticians, molecular biologists, linguists, system scientists and engineers.

The Contact Paradox by Keith Cooper Pdf

What will happen if (perhaps when) humanity makes contact with another civilisation on a different planet? In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilisations to our existence. Of course, we don't know if such civilisations really exist. For the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence. So far, SETI has found no evidence of extraterrestrial life, but with more than a hundred billion stars in our Galaxy alone to search, the odds of quick success are stacked against us. The silence from the stars is prompting some researchers to transmit more messages into space, in an effort to provoke a response from any civilisations out there that might otherwise be staying quiet. However, the act of transmitting raises troubling questions about the process of contact. In The Contact Paradox, author Keith Cooper looks at how far SETI has come since its modest beginnings, and where it is going, by speaking to the leading names in the field and beyond. SETI forces us to confront our nature in a way that we seldom have before – where did we come from, where are we going, and who are we in the cosmic context of things? This book considers the assumptions that we make in our search for extraterrestrial life, and explores how those assumptions can teach us about ourselves.

From Habitability to Life on Mars by Nathalie A. Cabrol,Edmond A. Grin Pdf

From Habitability to Life on Mars explores the current state of knowledge and questions on the past habitability of Mars and the role that rapid environmental changes may have played in the ability of prebiotic chemistry to transition to life. It investigates the role that such changes may have played in the preservation of biosignatures in the geological record and what this means for exploration strategies. Throughout the book, the authors show how the investigation of terrestrial analogs to early Martian habitats under various climates and environmental extremes provide critical clues to understand where, what and how to search for biosignatures on Mars. The authors present an introduction to the newest developments and state-of-the-art remote and in situ detection strategies and technologies that are being currently developed to support the upcoming ExoMars and Mars 2020 missions. They show how the current orbital and ground exploration is guiding the selection for future landing sites. Finally, the book concludes by discussing the critical question of the implications and ethics of finding life on Mars. Edited by the lead on a NASA project that searches for habitability and life on Mars leading to the Mars 2020 mission Presents the evidence, questions and answers we have today (including a summary of the current state of knowledge in advance of the ESA ExoMars and NASA Mars 2020 missions) Includes contributions from authors directly involved in past, current and upcoming Mars missions Provides key information as to how Mars rovers, such as ExoMars and Mars 2020, will address the search for life on Mars with their instrumentation

Conflicting Models for the Origin of Life by Stoyan K. Smoukov,Joseph Seckbach,Richard Gordon Pdf

Conflicting Models for the Origin of Life Conflicting Models for the Origin of Life provides a forum to compare and contrast the many hypotheses that have been put forward to explain the origin of life. There is a revolution brewing in the field of Origin of Life: in the process of trying to figure out how Life started, many researchers believe there is an impending second creation of life, not necessarily biological. Up-to-date understanding is needed to prepare us for the technological, and societal changes it would bring. Schrodinger’s 1944 “What is life?” included the insight of an information carrier, which inspired the discovery of the structure of DNA. In “Conflicting Models of the Origin of Life” a selection of the world’s experts are brought together to cover different aspects of the research: from progress towards synthetic life – artificial cells and sub-cellular components, to new definitions of life and the unexpected places life could (have) emerge(d). Chapters also cover fundamental questions of how memory could emerge from memoryless processes, and how we can tell if a molecule may have emerged from life. Similarly, cutting-edge research discusses plausible reactions for the emergence of life both on Earth and on exoplanets. Additional perspectives from geologists, philosophers and even roboticists thinking about the origin of life round out this volume. The text is a state-of-the-art snapshot of the latest developments on the emergence of life, to be used both in graduate classes and by citizen scientists. Audience Researchers in any area of astrobiology, as well as others interested in the origins of life, will find a modern and current review of the field and the current debates and obstacles. This book will clearly illustrate the current state-of-the-art and engage the imagination and creativity of experts across many disciplines.

The Little Book of Aliens by Adam Frank Pdf

“With wit and brio, Frank separates current nonsense about aliens from the serious and fascinating search for extraterrestrial life.” —Carlo Rovelli, New York Times bestselling author of Seven Brief Lessons on Physics From astrophysicist Adam Frank, a little book on the biggest questions in our search for extraterrestrial life, questions we stand ready to answer. Everyone is curious about life in the Universe, UFOs and whether ET is out there. Over the course of his thirty-year career as an astrophysicist, Adam Frank has consistently been asked about the possibility of intelligent life in the universe. Are aliens real? Where are they? Why haven’t we found them? What happens if we do? We’ve long been led to believe that astronomers spend every night searching the sky for extraterrestials, but the truth is we have barely started looking. Not until now have we even known where to look or how. In The Little Book of Aliens, Frank, a leading researcher in the field, takes us on a journey to all that we know about the possibility of life outside planet Earth and shows us the cutting-edge science that has brought us to this unique moment in human history: the one where we go find out for ourselves. In this small book with big stakes, Frank gives us a rundown of everything we need to know, from the scientific origins of the search for intelligent life, the Fermi Paradox, the Kardashev Scale, the James Webb Telescope, as well as UFOs and their conspiracy theories. Drawing from his own work and that of other scientists studying the possibility of alien life, he brings together the latest scientific thinking, data, ideas, and discoveries to equip us with the critical facts as we stand at what may be the last moment in human history where we still believe we are all alone. This book is about everything we do—and do not—know about life, intelligent or otherwise beyond Earth. In language that is engaging, entertaining and fun, The Little Book of Aliens provides a comprehensive first look at how close we are to finding out if others actually exist—and if they do, what they might be like. Humankind is on the precipice of finding its neighbors. What comes next? No person is better suited to answer that question—and lead the search—than Adam Frank.
