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.

Recent space missions to the outer solar system, Galileo (1996-2003) and Cassini-Huygens (2004-today), together with ground observations, have revealed that the moons of the outer solar system are enigmatic objects, introducing extraordinary challenges for geologists, astrobiologists, organic chemists, and planetologists. Chemical exchange exists through the different layers that form their interiors, and also from the interior to the surface. The most convincing evidence is certainly the discovery of water vapour and ice particles emerging from Enceladus's active south polar region. Evidence for exchange with a subsurface liquid ocean has also been provided by the inference of hydrated salts on the surfaces of Jupiter's moons, Europa and Ganymede, as well as the detection of sodium salts in particles originating in Enceladus's plumes. Aqueous exchange with the rocky core may also be possible, considering that 40Ar has been observed in the plumes of Enceladus during one flyby of Cassini and in the atmosphere of Titan. The ongoing CH4 replenishment in Titan's atmosphere is additional striking evidence of exchange processes within the moons.

There is a clear conspiracy to deny the existence of UFOs.

The mainstream media has misinformed us for years about UFO studies conducted by highly regarded scientists associated with some of the finest universities in the country. There is significant evidence that the U.S. government has covered up the alien presence through misinformation, distortion, obfuscation, and ridicule. Some prominent, politically connected scientists have engaged in the cover up. And a few professional writers have helped to successfully label any scientists who have been persuaded by the evidence and brave enough to take a stand as unscientific charlatans, fanatics, and kooks.

"Fact, Fiction, and Flying Saucers" examines the wealth of archival documents that clearly demonstrate this cooperative disinformation effort and refute the false claims made by these professional scoffers. Friedman and Marden set the record straight by examining politically motivated misinformation and presenting the compelling evidence that separates fact from fiction. They reveal:

- The most compelling UFO evidence, including a variety of large-scale scientific studies

- The current state of UFOlogy and what the future holds

- The media s role in disclosure and denial

- The government scientists whose job it is to deny

- The Air Force, FBI, CIA, and NSA s involvement

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 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.

""UFOs: God's Chariots?" offers a fascinating critical survey of the aerial phenomenon since it essentially began in 1947 . Highly recommended for reading and reflection."
--Robert Ellwood, Professor of World Religions, University of Southern California
"Peters' astrotheology takes us on a wise adventure into a lively cosmos, where neither 'belief ' nor 'unbelief ' answers the questions about UFOs and ETI."

--Catherine Keller, Professor of Theology, Drew University
Are UFOs celestial saviors, coming to save Earth from self-destruction?
Are UFOnauts advancing human evolution by birthing hybrid children?
Is it time for a new "astrotheology" that enshrines the UFO phenomenon at the same level as the space sciences at NASA and SETI?
"UFOs: God's Chariots?" uncovers and exposes the clandestine spiritual dimensions within the UFO phenomenon. UFOs vibrate with transcendence, omniscience, perfection, and redemption.
"UFOs: God's Chariots?" delves deeply into government conspiracies, analyzes the newest models of close encounter interpretation, and reveals the results of The Peters ETI Religious Crisis Survey, in which self-identified believers were asked if making contact with an intelligent extraterrestrial civilization would undermine our historic religious traditions. They said no.
Does this mean we're ready to share our pews with aliens?"

One of the most ambitious works of paranormal investigation of our time, here is an unprecedented compendium of pre-twentieth-century UFO accounts, written with rigor and color by two of today's leading investigators of unexplained phenomena.
In the past century, individuals, newspapers, and military agencies have recorded thousands of UFO incidents, giving rise to much speculation about flying saucers, visitors from other planets, and alien abductions. Yet the extraterrestrial phenomenon did not begin in the present era. Far from it. The authors of "Wonders in the Sky" reveal a thread of vividly rendered-and sometimes strikingly similar- reports of mysterious aerial phenomena from antiquity through the modern age. These accounts often share definite physical features- such as the heat felt and described by witnesses-that have not changed much over the centuries. Indeed, such similarities between ancient and modern sightings are the rule rather than the exception.
In "Wonders in the Sky," respected researchers Jacques Vallee and Chris Aubeck examine more than 500 selected reports of sightings from biblical-age antiquity through the year 1879-the point at which the Industrial Revolution deeply changed the nature of human society, and the skies began to open to airplanes, dirigibles, rockets, and other opportunities for misinterpretation represented by military prototypes. Using vivid and engaging case studies, and more than seventy-five illustrations, they reveal that unidentified flying objects have had a major impact not only on popular culture but on our history, on our religion, and on the models of the world humanity has formed from deepest antiquity.
Sure to become a classic among UFO enthusiasts and other followers of unexplained phenomena, "Wonders in the Sky" is the most ambitious, broad-reaching, and intelligent analysis ever written on premodern aerial mysteries.

Over the past ten years, the discovery of extrasolar planets has opened a new field of astronomy, and this area of research is rapidly growing, from both the observational and theoretical point of view. The presence of many giant exoplanets in the close vicinity of their star shows that these newly discovered planetary systems are very different from the solar system. New theoretical models are being developed in order to understand their formation scenarios, and new observational methods are being implemented to increase the sensitivity of exoplanet detections. In the present book, the authors address the question of planetary systems from all aspects. Starting from the facts (the detection of more than 300 extraterrestrial planets), they first describe the various methods used for these discoveries and propose a synthetic analysis of their global properties. They then consider the observations of young stars and circumstellar disks and address the case of the solar system as a specific example, different from the newly discovered systems. Then the study of planetary systems and of exoplanets is presented from a more theoretical point of view. The book ends with an outlook to future astronomical projects, and a description of the search for life on exoplanets. This book addresses students and researchers who wish to better understand this newly expanding field of research.

It was with pleasure that CAUP became for three days the core to the cloud of star formation experts all over the world. Close to the celebration of its 15th anniversary - therefore still in the early stages of institutional evolution - we are proud of our multiple activities in Astronomy: a productive research centre, classi?ed as "Institution of excellence" within the Portuguese research units, but also an "Institution of Public Utility" as recognised by the Government. Fifteen years ago we choose to play a role not only in research, as expected from any research centre but also in the training of the future astronomers and the promotion of science and scienti?c culture. This choice is clearly stated in our by-laws and also in the multiple activities we have carried out since. Along the years we have organized on a regular basis international Workshops similar to "Cores to Clusters." Sometimes we have chosen to organize int- national conferences of a larger size. On other occasions the choice has been for smaller and more informal discussion meetings. Or even doctoral schools with very different objectives. In common all those meetings have always had, besides the formal registered participants, a group of informal participants, our undergraduate students of Astronomy, so eager to be in touch with the real world.

UV radiation is an important part in the electromagnetic spectrum since the energy of the photons is great enough to produce important chemical reactions in the atmospheres of planets and satellites of our Solar System, thereby affecting the transmission of this radiation to the ground and its physical properties. Scientists have used different techniques (balloons and rockets) to access to the information contained in this radiation, but the pioneering of this new frontier has not been free of dangers.

The Sun is our main source of UV radiation and its description occupies the first two chapters of the book. The Earth is the only known location where life exists in a planetary system and therefore where the interaction of living organism with UV radiation can be tested through different epochs and on distinct species. The development of the human technology has affected the natural shield of ozone that protects complex lifeforms against damaging UV irradiation. The formation of the ozone hole and its consequences are described, together with the possible contribution of UV radiation to recent climate changes. Finally, we will discuss the the potential role of ultraviolet light in the development of life on bodies such as Mars, Europa and Titan.

The Solar System is not isolated; other external sources can contribute to the enhancement of the UV radiation in our environment. The influence of such events as nearby supernovae and gamma-ray bursts are described, together with the consequences to terrestrial life from such events.

This is the first collection of review articles in one volume covering the very latest developments in exoplanet research. This edited, multi-author volume will be an invaluable introduction and reference to all key aspects in the field this field. The reviews cover topics such as the properties of known exoplanets and searching for exoplanets in the stellar graveyard. The book provides an easily accessible point of reference in a fast moving and exciting field.

Cathodoluminescence microscopy/spectroscopy is a powerful technique providing detailed information on the shock metamorphism of target rocks, biosignatures of meteorites and mineralogy of the pre-solar grains. Moreover, it can be used as an in-situ method to classify the solid-atmospheric-liquid interactions on the surface of Mars.

This volume considers the role comets may have played in the origins and evolution of life. This is the only book dealing in depth with this subject. It is particularly relevant in light of recent investigations of Halley's comet, of new insights into organic synthesis in meteorites and comets, and of new results of numerical simulations of cometary orbits and impacts on Earth. The book is intended as a comprehensive review of current research.

Where were the amino acids, the molecules of life, created: perhaps in a lightning storm in the early Earth, or perhaps elsewhere in the cosmos? This book argues that at least some of them must have been produced in the cosmos, and that the fact that the Earthly amino acids have a specific handedness provides an important clue for that explanation. This book discusses several models that purport to explain the handedness, ultimately proposing a new explanation that involves cosmic processing of the amino acids produced in space. This book provides a tour for laypersons that includes a definition of life, the Big Bang, stellar nucleosynthesis, the electromagnetic spectrum, molecules, and supernovae and the particles they produce.

Micrometeorites played an essential role in the formation of the atmosphere of the Early Earth and also served as a significant source of activation for organic prebiotic chemistry on mineral surfaces. The present book gives a coherent account of this scenario, embedding the more specific results within a broader framework that considers the creation and evolution of the Early Earth. It thus addresses students and nonspecialist researchers in the fields of planetary atmospheres, biogeophysics and astrobiology. The experienced researcher will find this volume to be a modern and compact reference, as well as a source of material for lectures in this field.

This interdisciplinary book probes the subject of extraterrestrial intelligent life, offering scientific and technological implications, discussing the philosophical and religious connotations and rebuffing pseudo-scientific assertions such as 'rare earth'. The author discusses such philosophical questions as: What is intelligence? What is consciousness? Should we expect ETIs to be conscious beings? Also discussed is the viability of future astronautics which would enable closer human contact with ETI.

This book examines the origins, development and fate of intelligent species in the observable part of our universe. It scrutinizes what kind of information about extraterrestrial intelligent life can be inferred from our own biological, cultural and scientific evolution and the likely future of mankind. There is emphasis on the geological conditions and consequences of life's conquest of land as the pre-condition for the emergence of life with our type of technical intelligence.

IF YOU THOUGHT THAT THE X-FILES WAS ONLY FICTION, THINK AGAIN!

For as long as extraterrestrial and paranormal phenomena have been investigated, the official government response to any events deemed "otherworldly" or unexplainable has been well documented: DENIAL. Not because they aren't interested in UFOs, monsters, and psychic abilities -- but because they have their own secret agendas for using this knowledge.

In this thoroughly researched compendium of conspiracies and cover-ups, the remarkable findings that have been documented (and supposedly debunked) by the governments of the United States, Great Britain, and the former Soviet Union are finally revealed, including

• Attempts by the U.S. Air Force to build a fleet of nuclear-powered flying saucers...
  
• The British military's files on the Loch Ness monster and other mysterious beasts...
  
• The Cold War race between the CIA and the KGB to create the perfect psychic spy/assassin...
  
• The real story behind the enigmatic "Men in Black," who terrify UFO witnesses into silence...
  

For anyone who wants to know the truth -- or the truth behind the truth -- Strange Secrets is the ultimate resource to understanding exactly what the government doesn't want us to know -- and why they want to keep us in the dark.

Richard M. Dolan is a gifted historian whose study of U.S. Cold War strategy led him to the broader context of increased security measures and secrecy since World War II. One aspect of such government policies that has continued to hold the public's imagination for over half a century is the question of unidentified flying objects.

UFOs and the National Security State is the first volume of a two-part detailed chronological narrative of the national security dimensions of the UFO phenomenon from 1941 to the present. Working from hundreds of declassified records and other primary and secondary sources, Dolan centers his investigation on the American military and intelligence communities, demonstrating that they take UFOs seriously indeed.

Included in this volume are the activities of more than fifty military bases relating to UFOs, innumerable violations of sensitive airspace by unknown craft and analyses of the Roswell controversy, the CIA-sponsored Robertson Panel, and the Condon Committee Report. Dolan highlights the development of civilian anti-secrecy movements, which flourished in the 1950s and 1960s until the adoption of an official government policy and subsequent "closing of the door" during the Nixon administration.

In the last decade, the number of reports of alien spacecraft sightings has skyrocketed. However, the phenomenon of alien encounters is not new. Here, for the first time, two UFO experts, Kevin Randle and Russ Estes, cover the history of UFO sightings, from the ancient to the modern, using research from many different sources, including the Air Force and private UFO groups. Each of the more than one hundred entries is based on actual eyewitness accounts and includes:

• A detailed drawing of each spaceship based on photographs or drawings made by the people who saw it with their own eyes
  
• A concise summary of the facts: where the sighting took place, names of the witnesses, craft type, and such specifics as each craft's dimensions, color, sound, and exhaust mechanism
  
• A unique reliability rating, on a scale from 0 to 10
  
• A gripping you-were-there narration of the encounter, along with meticulous documentation of source material
  

Spaceships of the Visitors is a fascinating and essential reference for anyone curious about alien visitation.
