If you are interested in how researchers plan to search the heavens for signs of intelligent life, you should have this book. SETI 2020 is a new, and remarkably comprehensive study of how scientists busy with the Search for Extraterrestrial Intelligence (SETI) should direct their efforts between now and the year 2020. Distilling the work of dozens of top SETI experts, astronomers, and technology mavens, this book gives an overview of the problem of finding evidence for extraterrestrial technologies, and how to best address it. New radio telescopes consisting of large arrays of relatively small antennas are proposed and detailed. So are new types of antennas that can survey the entire sky at once. Of particular interest is the extensive treatment of optical SETI -- the search for signals beamed our way using high-powered, pulsed lasers or their equivalent. A book that's interesting for both the layman and the technically sophisticated, SETI 2020 is the definitive publication in this fascinating field.

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.

Mathematics is as much a part of our humanity as music and art. And it is our mathematics that might be understandable, even familiar, to a distant race and might provide the basis for mutual communication. This book discusses, in a conversational way, the role of mathematics in the search for extraterrestrial intelligence. The author explores the science behind that search, its history, and the many questions associated with it, including those regarding the nature of language and the philosophical/psychological motivation behind this search.

Based on the latest missions results and supported by commissioned artwork, this book explores the possible lessons we may learn from exoplanets. As the number of known Earth-like objects grows significantly, the author explores what is known about the growing roster of "pale blue dots" far afield. Aided by an increased sensitivity of the existing observatories, recent discoveries by Keck, the Hubble Space Telescope, and Kepler are examined. These findings, once thought to be closer to the realm of science fiction, have fired the imaginations of the general public as well as scientists. All of us are mesmerized by the possibility of other Earth-like worlds out there. Author Michael Carroll asks the tough questions of what the expected gain is from identifying these Earth analogs spread across the Universe and the reasons for studying them. Potentially, they could teach us about our own climate and Solar System. Also explored are the more remote options of communication between or even travel to these distant yet perhaps not so dissimilar worlds.

This book offers a vision of how evolutionary life processes can be modelled. It presents a mathematical description that can be used not only for the full evolution of life on Earth from RNA to modern human societies, but also the possible evolution of life on exoplanets, thus leading to SETI, the current Search for ExtraTerrestrial Intelligence. The main premise underlying this mathematical theory is that the Geometric Brownian Motion (GBM) can be applied as a key stochastic process to model the evolution of life. In the resulting Evo-SETI Theory, the life of any living thing (a cell, an animal, a human, a civilization of humans, or even an ET civilization) is represented by a b-lognormal, i.e., a lognormal probability density function starting at a precise instant (b, birth) then increasing up to a peak time, then decreasing to senility time and then continuing as a straight line down to the time of death. Using this theory, Claudio Maccone arrives at remarkable hypotheses on the development of life and civilizations, the possibility of extraterrestrial life, and when computers will take over the reins from us humans (Singularity). The book develops the mathematical Evo-SETI Theory by integrating a set of articles that the author has published in various journals on Astrobiology and Astronautical Research.

This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.

As space continues to attract substantial public and private investment and has become ever more active, the third edition of this book has been updated to cover recent developments. This includes the legal bases of UN Resolution 76/3, the Space3030 Agenda, which envisages ‘space as a driver of sustainable development’ and sets out an extensive programme for the future. The work also takes account of adaptations and augmentations to basic space treaties. It examines the increasing commercialisation of space in areas such as space tourism and space mining, for which four states have already adopted relevant legislation. The impact of new technologies such as satellite constellations and micro-satellites are also scrutinised. At a time when space tourism is available to those who can afford it and when the moon will shortly be revisited with a prospect of permanent bases, this third edition provides a firm base for the next generation of space lawyers. As with previous editions, the work draws from governmental, international organisational and other authoritative sources as well as the relevant literature in the field. The book will be an essential and comprehensive resource for students, academics and researchers as well as space agencies, governments and space-active companies. It will also be of value to technical operatives and managers who need to know the legal context within which they work.

The majority of books dealing with prospects for interstellar flight tackle the problem of the propulsion systems that will be needed to send a craft on an interstellar trajectory. The proposed book looks at two other, equally important aspects of such space missions, and each forms half of this two part book. Part 1 looks at the ways in which it is possible to exploit the focusing effect of the Sun as a gravitational lens for scientific missions to distances of 550 AU and beyond into interstellar space. The author explains the mechanism of the Sun as a gravitational lens, the scientific investigations which may be carried out along the way to a distance of 550 AU (and at the 550 AU sphere itself), the requirements for exiting the Solar System at the highest speed and a range of project ideas for missions entering interstellar space. Part 2 of the book deals with the problems of communicating between an interstellar spaceship and the Earth, especially at very high speeds. Here the author assesses a range of mathematical tools relating to the Karhunen-Loève Transform (KLT) for optimal telecommunications, technical topics that may one day enable humans flying around the Galaxy to keep in contact with the Earth. This part of the book opens with a summary of the author’s 2003 Pešek Lecture presented at the IAC in Bremen, which introduces the concept of KLT for engineers and ‘newcomers’ to the subject. It is planned to include a DVD containing the full mathematical derivations of the KLT for those interested in this important mathematical tool whilst the text itself will contain the various results without outlines of the mathematical proofs. Astronautical engineers will thus be able to see the application of the results without getting bogged down in the mathematics.
