This book is a collection of essays written by the very scientists and engineers who have led, and continue to lead, the scientific quest known as SETI, the search for extraterrestrial intelligence. Divided into three parts, the first section, 'The Spirit of SETI Past', written by the surviving pioneers of this then emerging discipline, reviews the major projects undertaken during the first 50 years of SETI science and the results of that research.

In the second section, 'The Spirit of SETI Present', the present-day science and technology is discussed in detail, providing the technical background to contemporary SETI instruments, experiments, and analytical techniques, including the processing of the received signals to extract potential alien communications.

In the third and final section, 'The Spirit of SETI Future', the book looks ahead to the possible directions that SETI will take in the next 50 years, addressing such important topics as interstellar message construction, the risks and assumptions of interstellar communications, when we might make contact, what aliens might look like and what is likely to happen in the aftermath of such a contact.

Finally a book that answers the tough questions about UFOs, Gilmer reveals rare information about little green men and more.

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.

For years, the public has been led to believe that the US government and the military have tried to cover up the recovery of a crashed saucer and its alien occupants from near Roswell, New Mexico. This belief has been fostered by numerous books, newspaper articles, TV shows, and movies released since the incident of 1947. After many years of investigation, Philip J. Klass (the Sherlock Holmes of UFOlogy), has uncovered hard evidence that there is indeed a cover-up, 'but not by the US government'. This is based on solid evidence contained in once 'secret' and 'top secret' Air Force and CIA documents whose contents were intentionally withheld by authors of books and articles on Roswell, as well as by those who produced TV shows on the subject. Here, Klass discloses what really crashed on the Brazel ranch. He also reveals serious flaws in the tales told by alleged witnesses, some of whom have drastically changed their accounts.

The purpose of this book is to initiate a new discussion on liberty focusing on the infinite realms of space. The discussion of the nature of liberty and what it means for a human to be free has occupied the minds of thinkers since the Enlightenment. However, without exception, every one of these discussions has focused on the character of liberty on the Earth. The emergence of human space exploration programs in the last 40-50 years raise a fundamental and new question: what will be the future of liberty in space? This book takes the discussion of liberty into the extraterrestrial environment. In this book, new questions will be addressed such as: Can a person be free when the oxygen the individual breathes is the result of a manufacturing process controlled by someone else? Will the interdependence required to survive in the extremities of the extraterrestrial environment destroy individualism? What are the obligations of the individual to the extraterrestrial state? How can we talk of extraterrestrial liberty when everyone is dependent on survival systems?

For centuries, from the earliest legends of the man on the moon, mankind has fantasized and speculated about other life in the universe. With the discovery of biochemical evolution - which showed how life could evolve out of simple compounds - those speculations took on a new dimension. Most scientists now believe that it is possible that there is other intelligent life in the universe.
What are the possibilities of our making contact with ETIs in the profound vastness of space (a problem, as Isaac Asimov notes, too easily dismissed by cultists)? What will be the consequences to our images of ourselves and our world of the first proven contact with beings from another planet, since they are likely to be of superior intelligence? Could we still believe in the value of life as we live it? How would it affect mankind's religions, both Western and Eastern? Would it in fact mean, as Arthur C. Clarke has said, an end to mankind's childhood?
These and other questions are explored in Extraterrestrial Intelligence - from the most practical issues, such as how the news of contact should be handled, to the most exciting and troubling questions of philosophy, religion, and science.
Extraterrestrial Intelligence begins the search for a cosmic context for mankind. It leads the way in reflecting on the next stage in our gradual self-discovery.

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.

In 1988, in an article on the analysis of the measurements of the variations in the radial velocities of a number of stars, Campbell, Walker, and Yang reported an - teresting phenomenon;the radial velocity variations of Cephei seemed to suggest the existence of a Jupiter-like planet around this star. This was a very exciting and, at the same time, very surprising discovery. It was exciting because if true, it would have marked the detection of the ?rst planet outside of our solar system. It was surprising because the planet-hosting star is the primary of a binary system with a separation less than 19 AU, a distance comparable to the planetary distances in our solar system. The moderatelyclose orbit of the stellar companionof Cephei raised questions about the reality of its planet. The skepticism over the interpretation of the results (which was primarily based on the idea that binary star systems with small sepa- tions would not be favorable places for planet formation) became so strong that in a subsequent paper in 1992, Walker and his colleagues suggested that the planet in the Cephei binary might not be real, and the variations in the radial velocity of this star might have been due to its chromospheric activities.

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.

IF UFOS DON'T EXIST, THEN THEY CAN'T CRASH. But something did crash near Corona, a tiny town not far from Roswell, New Mexico, in 1947. And that crash has been dissected and debated ever since. Aviation/science writer Don Berliner and nuclear physicist Stanton Friedman, the original civilian investigator of the so-called Roswell incident, have delved into the controversy to find the truth. They sifted through once-classified government documents, interviewed military and civilian witnesses, pieced together evidence, considered alternative theories, and concluded that a UFO crashed near Corona-and the U.S. government knew it and covered it up. Crash at Corona proves that what was found in the New Mexico desert wasn't a weather balloon or a secret weapon-it was a UFO. "One of the more credible books arguing the existence of UFOs...Most arresting of all is the testimony of those who handled the debris, who had no opportunity to compare notes, yet have described the materials ...in almost identical language."-Publishers Weekly DON BERLINER has written more than 300 magazine articles and 25 books on aviation history and space and was also a staff writer for the National Investigations Committee on Aerial Phenomena (NICAP). He is board chairman of the non-profit Fund for UFO Research, Inc., and is a delegate to the UFO Research Coalition. STANTON T. FRIEDMAN is a nuclear physicist who has worked for General Electric, General Motors, Westinghouse, and other corporations. He is also the author of TOP SECRET/MAJIC and has appeared on Larry King, Unsolved Mysteries, and Nightline, and was involved with the documentaries UFOs Are Real and Flying Saucers Are Real. He was the final speaker at the fiftieth anniversary conference at the International UFO Museum and Research Center at Roswell, and has given more than 700 lectures on the subject of UFOs.

Here is the first A–Z encyclopedia to explore the convictions held by many in the modern day world that extraterrestrials, angels, fairy-folk, and other-dimensional intelligences regularly interact with human beings. Extraordinary Encounters: An Encyclopedia of Extraterrestrials and Otherworldly Beings is the first ever illustrated A–Z encyclopedia to explore these fascinating modern day beliefs, personalities, beings, and events. Among the beings you'll meet in its pages are Abraham, a collection of highly evolved entities that speak in one voice; Metranon, the divine interface between God and the Outer Worlds (and sometime Old Testament angel); and The Planetary Council, whose members include Jove, Merlin, Quetzalcoatl, and Lao-Tzu.

This volume provides an in-depth discussion on the central question - how can people express and survive dissent and disagreement in confined habitats in space? The discussion is an important one because it could be that the systems of inter-dependence required to survive in space are so strong that dissent becomes impossible. John Locke originally said that people have a right to use revolution to overthrow a despotic regime. But if revolution causes violence and damage that causes depressurisation with the risk of killing many people, is it even permissible to have a revolution? How then are people to express their liberty or dissatisfaction with their rulers? The emergence of structures of dissent and disagreement is an essential part of the construction of a framework of liberty in space (revolution is just the extreme example) and thus the topic deserves in-depth and immediate attention. Even today, the way in which we assemble organisations and corporations for the government and private exploration of space must take into account the need for mechanisms to allow people to express dissent.
