Systematically explores the early origins and basic definition of life.

Investigates the major theories of the origins of life in light of modern research with the aim of distinguishing between the necessary and the optional and between deterministic and random influences in the emergence of what we call life.

Treats and views life as a cosmic phenomenon whose emergence and driving force should be viewed independently from its Earth-bound natural history.

Synthesizes all the fundamental life-related developments in a comprehensive scenario, and makes the argument that understanding life in its broadest context requires a material-independent perspective that identifies its essential fingerprints

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.

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.

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.

How did life begin on the early Earth? We know that life today is driven by the universal laws of chemistry and physics. By applying these laws over the past ?fty years, en- mous progress has been made in understanding the molecular mechanisms that are the foundations of the living state. For instance, just a decade ago, the ?rst human genome was published, all three billion base pairs. Using X-ray diffraction data from crystals, we can see how an enzyme molecule or a photosynthetic reaction center steps through its catalytic function. We can even visualize a ribosome, central to all life, translate - netic information into a protein. And we are just beginning to understand how molecular interactions regulate thousands of simultaneous reactions that continuously occur even in the simplest forms of life. New words have appeared that give a sense of this wealth of knowledge: The genome, the proteome, the metabolome, the interactome. But we can't be too smug. We must avoid the mistake of the physicist who, as the twentieth century began, stated con?dently that we knew all there was to know about physics, that science just needed to clean up a few dusty corners. Then came relativity, quantum theory, the Big Bang, and now dark matter, dark energy and string theory. Similarly in the life sciences, the more we learn, the better we understand how little we really know. There remains a vast landscape to explore, with great questions remaining.

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.

"Dr. Ardy Sixkiller Clarke has for more than 20 years done a tremendous amount of field work and has carefully and with spiritual sensitivity collected these stories from the original witnesses. This book is an impressive documentation of the scope and depth of the UFO enigma."
--Hakan Blomqvist, Cofounder and Chairman, Archives for UFO Research (AFU), Sweden
Dr. Ardy Sixkiller Clarke, author of Encounters With Star People, vowed as a teenager to follow in the footsteps of two 19th-century explorers, John L. Stephens and Frederick Catherwood, who brought the ancient Maya cities to the world's attention. Dr. Clarke set out on a seven-year adventure (from 2003 through 2010) through Belize, Honduras, Guatemala, and Mexico, collecting stories of encounters, sky gods, giants, little people, and aliens among the indigenous people. She drove more than 12,000 miles, visiting 89 archaeological sites (Stephens and Catherwood visited only 44) and conducting nearly 100 individual interviews.
The result is an enthralling series of unique, original, true stories of encounters with space travelers, giants, little people, and UFOs. "Sky People" may very well change the way you perceive and experience the world.

The Quest To Discover Life Beyond Earth.

"The 'dreams' that I write of are not the usual ones, the images that come up in our minds involuntarily during certain stages of sleep, but rather the hopes and expectations that we have lavished upon other worlds around us."—from the Preface.

The surprisingly long history of debate over extraterrestrial life is full of marvelous visions of what life "out there" might be like, as well as remarkable stories of alleged sightings and heated disputes about the probability that life might actually have arisen more than once. In Planetary Dreams, acclaimed author Robert Shapiro explores this rich history of dreams and debates in search of the best current answers to the most elusive and compelling of all questions: Are we alone?

In his pursuit, he presents three contrasting views regarding how life might have started: through Divine Creation, by a highly unlikely stroke of luck, or by the inevitable process of a natural law that he terms the Life Principle. We are treated to a lively fictional dinner debate among the leading proponents of these schools of thought—with the last named group arguing that life has almost surely formed in many places throughout the universe, and the others that life may well be entirely unique to our own blue planet. To set the stage for a deep exploration of the question, the author then leads us on a fantastic journey through the museum of the cosmos, an imagined building that holds models of the universe at different degrees of magnification. We then journey deep into inner space to view the astonishingly intricate life of a single cell, and learn why the origin of such a complex object from simple chemical mixtures poses one of the most profound enigmas known to science.

Writing in a wonderfully entertaining style, Shapiro then reviews the competing theories about the start of life on Earth, and suggests the debate may best be settled by finding signs of life on the other worlds of our solar system. He takes us on a guided tour of the most likely sites, from the underground hot springs of Mars to the ice-covered oceans of Jupiter's airless moons.

Along the way, he shares a wealth of fascinating stories about the ways in which our views of the heavens have changed, from the theories of ancient philosphers, who argued that the Moon was inhabited, to the current Origins and Astrobiology initiatives of NASA. He describes the probes that will be sent out in the near future in pursuit of the first compelling physical evidence of life beyond Earth, and concludes with a radical suggestion about how this quest might be supported through the next millennium. As we launch into an exciting new era of space exploration, Planetary Dreams offers a thoughtful and entertaining exploration of both the history of our hopes and expectations and a vision of a possible future in which the discovery of life elsewhere will provide a new view of our place in the universe.

This no-nonsense guide to one of our most enduring mysteries presents a short history of the strangest encounters, looks carefully at explanations from the blunt to the truly bizarre, offers insights into the strongest evidence that we are being visited by beings from another world and sources the best sceptical arguments that it can all be explained rationally. Concise, balanced and - occasionally - hilarious this is a story that has as much to tell you about the human race as it does about aliens.

Seeking the truth about UFOs in America, Mark Pilkington and John Lundberg uncover a 60 year-old story stranger than any conspiracy thriller. Through the fascinating account of their quest Mark Pilkington reveals the long history of UFOria and its parallels in little known tales from the murky worlds of espionage, psychological warfare and advanced military technology. Along the way he discovers that the truth about flying saucers is stranger and more complex than either the ufologists or debunkers would have us believe. As he crossed the US meeting intelligence agents, disinformation specialists and UFO hunters Pilkington was confronted with a dizzying array of ever more outrageous claims and counter claims. As a result he began to suspect that, instead of covering up stories of crashed flying saucers, alien contacts and secret underground bases, the US intelligence agencies had actually been promoting them all along. Meanwhile he has to deal with his own uncertainties, the suspicions of the UFO community and a partner who is starting to believe that conspiracy theorists might be right after all. With a fresh, funny and objective approach, Pilkington is the ideal guide to steer us through these strange territories, where nothing is quite as it seems and reality is just a matter of managing perceptions.

This book introduces the reader to the wonders of Mars, covering all aspects from our past perceptions of the planet through to the latest knowledge on its history, its surface processes such as impact cratering, volcano formation, and glaciation, and its atmosphere and climate. In addition, a series of ten intriguing open issues are considered in a more advanced way. These include such thought-provoking questions as What turned off the planet's magnetic field?, Why are the northern and southern hemispheres so different?, What was the fate of the once abundant water?, and Is there, or was there, life on Mars? Numerous original figures, unavailable elsewhere, reproduce details of images from Viking, CTX, MOC, HiRISE, THEMIS, and HRSC. The book will appeal especially to general readers interested in planetary sciences, astronomy, astrogeology, and space exploration and to students of Earth Sciences and Natural and Environmental Sciences. The higher-level material on the remaining mysteries of Mars will also be of interest to astrogeologists and other researchers.

On 28 May 1955, an announcement was made by The Cosmic Masters, through the unique Yogic abilities of the author, that a Spacecraft would come into orbit of the Planet Earth for a number of days each year to send great spiritual Healing powers to ALL people on Earth.

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

This true account of the aliens who invaded the town of Point Pleasant, West Virginia - first published in 1975 - has been made into a major motion picture starring Richard Gere, Laura Linney and Alan Bates. For thirteen months Point Pleasant was plagued by a dark terror that culminated in a major disaster. Unearthly noises and ghostly lights in the sky gave way to mutilated animals, winged monsters, weird flying machines and worst of all, the fearsomely demonic "Bird" - the Mothman. The story reads like a novel - but every single word of it is true and fully documented by john A. Keel, who spent a year in Point Pleasant where he saw and experienced many of the stranger manifestations personally.
