Book Description
In April 2010, fifty years to the month after the first experiment in the Search for Extraterrestrial Intelligence (SETI), scholars from a range of disciplines—including astronomy, mathematics, anthropology, history, and cognitive science—gathered at NASA's biennial Astrobiology Science Conference (AbSciCon) for a series of sessions on the search for intelligent life. This book highlights the most recent developments in SETI discussed at that conference, emphasizing the ways that SETI has grown since its inception. The volume covers three broad themes: First, leading researchers examine the latest developments in observational SETI programs, as well as innovative proposals for new search strategies and novel approaches to signal processing. Second, both proponents and opponents of "Active SETI" debate whether humankind should be transmitting intentional signals to other possible civilizations, rather than only listening. Third, constructive proposals for interstellar messages are juxtaposed with critiques that ask whether any meaningful exchange is possible with an independently evolved civilization, given the constraints of contact at interstellar distances, where a round-trip exchange could take centuries or millennia. As we reflect on a half-century of SETI research, we are reminded of the expansion of search programs made possible by technological and conceptual advances. In this spirit of ongoing exploration, the contributors to this book advocate a diverse range of approaches to make SETI increasingly more powerful and effective, as we embark on the next half-century of searching for intelligence beyond Earth.

Book Description
The first international conference on the problem of extraterrestrial civilizations, and contact with them, was held in September 1971 in Soviet Armenia. The conference was a gathering of specialists working in a wide variety of fields—astronomy, physics, radiophysics, computer science and technology, chemistry, biology, linguistics, archaeology, anthropology, sociology, and history—and included many scientists whose reputations are worldwide. For example, Freeman Dyson, Philip Morrison, and Charles Townes were among the American participants; their Russian counterparts were of comparable distinction. The conference was jointly organized by the U.S. National Academy of Sciences (with assistance from the U.S. National Science Foundation) and the U.S.S.R. Academy of Sciences. Scientists from several other countries also participated. Many aspects of the problem of extraterrestrial civilizations were discussed in detail, and these discussions are fully presented in this book. Particular attention is devoted to the following questions: the plurality of planetary systems in the universe, the origin of life on Earth, the possibility of life arising on cosmic bodies, the origin and evolution of intelligence, the origin and development of technological civilizations, problems in searching for intelligent signals or for evidence of astroengineering activities, and the problems and possible consequences of establishing contact with extraterrestrial civilizations.

Book Description
If we send a message into space, will extraterrestrial beings receive it? Will they understand? The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings' various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe? Oberhaus describes, among other things, a late-nineteenth-century idea to communicate with Martians via Morse code and mirrors; the emergence in the twentieth century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence); the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry; and the launching of a theremin concert for aliens. He considers media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and discusses attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica). The chosen medium for interstellar communication reveals much about the technological sophistication of the civilization that sends it, Oberhaus observes, but even more interesting is the information embedded in the message itself. In Extraterrestrial Languages, he considers how philosophy, linguistics, mathematics, science, and art have informed the design or limited the effectiveness of our interstellar messaging.

Book Description
Communication with Extraterrestrial Intelligence is devoted to the concepts and studies related to the science, technology, and observational techniques of communication with extraterrestrial intelligence (CETI). Topics covered range from the search for extraterrestrial intelligence (SETI) to the theory of interstellar communication; the problem of the origin of life; radio signals from extraterrestrial civilizations; and interstellar communication by neutrino beams. An infinitely expandable space radiotelescope is also described. This book is comprised of 21 chapters and opens with a discussion on the CETI activities of the International Academy of Astronautics (IAA) from 1965 to 1976 and describes the outlook for the IAA CETI Standing Committee. The following chapters sketch the background and rationale for a SETI program; the significance of the detection of signals and of information that may be contained in signals from extraterrestrial civilizations; an extended Drake's equation, the longevity-separation relation, equilibrium, inhomogeneities, and chain formation; and the physical and psychological basis for the belief that a band of frequencies called the water hole is a prime band for SETI. This monograph will appeal to practitioners in the fields of astrophysics, astronomy, planetary formation, exobiology, and biological evolution.

Book Description
Have you ever wondered what could happen when we discover another communicating species outside the Earth? This book addresses this question in all its complexity. In addition to the physical barriers for communication, such as the enormous distances where a message can take centuries to reach its recipient, the book also examines the biological problems of communicating between species, the problems of identifying a non-Terrestrial intelligence, and the ethical, religious, legal and other problems of conducting discussions across light years. Most of the book is concerned with issues that could impinge on your life: how do we share experiences with ETI? Can we make shared laws? Could we trade? Would they have religion? The book addresses these and related issues, identifying potential barriers to communication and suggesting ways we can overcome them. The book explores this topic through reference to human experience, through analogy and thought experiment, while relying on what is known to-date about ourselves, our world, and the cosmos we live in.

Book Description
Astronomers around the world are pointing their telescopes toward the heavens, searching for signs of intelligent life. If they make contact with an advanced alien civilization, how will humankind respond? In thinking about first contact, the contributors to this volume present new empirical and theoretical research on the societal dimensions of the Search for Extraterrestrial Intelligence (SETI). Archaeologists and astronomers explore the likelihood that extraterrestrial intelligence exists, using scientific insights to estimate such elusive factors as the longevity of technological societies. Sociologists present the latest findings of novel surveys, tapping into the public’s attitudes about life beyond Earth to show how religion and education influence beliefs about extraterrestrials. Scholars from such diverse disciplines as mathematics, chemistry, journalism, and religious studies offer innovative solutions for bridging the cultural gap between human and extraterrestrial civilizations, while recognizing the tremendous challenges of communicating at interstellar distances. At a time when new planets are being discovered around other stars at an unprecedented rate, this collection provides a much needed guide to the human impact of discovering we are not alone in the universe.

Book Description
By drawing on the complex interplay of ecology and feminism, ecofeminists identify links between the domination of nature and the oppression of women. This volume introduces a variety of innovative approaches for advancing ecofeminist activism, demonstrating how words exert power in the world. Contributors explore the interconnections between the dualisms of nature/culture and masculine/feminine, providing new insights into sex and technology through such wide-ranging topics as canine reproduction, orangutan motherhood and energy conservation. Ecofeminist rhetorics of care address environmental problems through cooperation and partnership, rather than hierarchical subordination, encouraging forms of communication that value mutual understanding over persuasion and control. By critically examining ways that theory can help deconstruct domineering practices—exposing the underlying ideologies—a new generation of ecofeminist scholarship illuminates the transformative capacity of language to foster emancipation and liberation.
