From the Earth's atmosphere to the edges of our Universe, the presence of dust is ubiquitous. One of the main challenges in studying dust in these various environments is thus to harmonize the diverse research techniques and results, including in-situ measurement, remote observation, laboratory experiments and modelling, and analysis of returned samples. For the first time in over a decade, this volume accomplishes exactly that, providing an overarching picture of the current state of dust science and research. Where possible, the papers in this volume emphasize the interconnections, similarities, and differences in the field, synthesizing results from several techniques into one cohesive view. Importantly, astrobiological connections have now been considered. The dust hazard, future technology and research, and space mission requirements and scenarios are also addressed. The outcome of this endeavor is an interdisciplinary compendium with a unified perspective on cosmic dust science.

Exploring the myths, stories, history and facts of documented encounters, mysterious experiences and unexplained visitors, Real Visitors, Voices From Beyond, and Parallel Dimensions by Brad Steiger and Sherry Hansen Steiger examines the 'other' forms, entities and beings inhabiting our universe. Building on their decades of research into the paranormal, mystical and supernatural, the Steigers analyse the influences and theories behind these mysterious visitors, whether they appear as aliens, ghosts, spirits, angels, demons, monsters or some other form.

This is the story of one woman's life-long interaction with beings from another world, and her journey to go beyond the fear to find meaning and purpose. In this book she explores the abduction experience and shares with you the three important things they insisted she learn.

Almost daily all over the world, accounts of UFO sightings, close encounters with ufonauts and even claims of alien abduction are reported. But far from being a recent phenomenon, research shows that inexplicable objects had been seen in Earth's skies for thousands of years. Yet controversy still rages over UFOs. Many people refuse to believe that UFO reports are anything more than hoaxes, hallucinations or merely the results of human error. And until now an objective, historical single volume catalogue of UFO sightings has not previously been available to the general public. Now, at last, readers can make up their own minds about the true nature of the UFO phenomenon. UFO Witness Sightings describes hundreds of UFO reports in chronological order from ancient Egypt to the present day. All the landmark cases are included, such as the 1961 Betty and Barney abduction claim and the Trindade Island photographs. Illustrated with more than 350 colour and black-and-white photographs and artworks, UFO Witness Sightings is written by a UFO expert and will appeal to anyone interested in the world of the unexplained.

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.

This book provides a comprehensive overview of the chemistry of CO2 in relation to surface interactions and photocatalytic transformation by UV radiation. The first part deals with the modelling of an anatase surface, its interaction with CO2, and the spontaneous exchange of oxygen atoms between the gas and solid phases. The book then naturally transitions to the photocatalytic reduction of CO2, achieved by adding UV radiation and traces of water to the experimental system, to produce methane and CO. This photocatalytic reduction is explained in detail and the implications for planetary chemistry (specifically concerning Mars), as well as Earth's atmospheric chemistry and global warming, are discussed.

Like planets in our solar system, exoplanets form, evolve, and interact with their host stars in many ways. As exoplanets acquire material and grow to the final size, their atmospheres are subjected to intense UV and X-radiation and high-energy particle bombardment from the young host star. Whether a planet can retain its atmosphere and the conditions for significant mass loss both depend upon the strength of the host star's high-energy radiation and wind, the distance of the exoplanet from its host star, the gravitational potential of the exoplanet, and the initial chemical composition of the exoplanet atmosphere. This introductory overview describes the physical processes responsible for the emission of radiation and acceleration of winds of host stars that together control the environment of an exoplanet, focusing on topics that are critically important for understanding exoplanetary atmospheres but are usually not posed from the perspective of host stars. Accordingly, both host stars and exoplanets are not studied in isolation but are treated as integrated systems. Stellar magnetic fields, which are the energy source for activity phenomena including high-energy radiation and winds, play a critical role in determining whether exoplanets are habitable. This text is primarily for researchers and graduate students who are studying exoplanet atmospheres and habitability, but who may not have a background in the physics and phenomenology of host stars that provide the environment in which exoplanets evolve. It provides a comprehensive overview of this broad topic rather than going deeply into many technical aspects but includes a large list of references to guide those interested in pursuing these questions. Nonspecialists with a scientific background should also find this text a valuable resource for understanding the critical issues of contemporary exoplanet research.

Is the Search for Extra Terrestrial Intelligence a genuine scientific research programme? David Lamb evaluates claims and counter-claims, and examines recent attempts to establish contact with other intelligent life forms. He considers the benefits and drawbacks of this communication, how we should communicate and whether we actually can. He also assesses competing theories on the origin of life on Earth, discoveries of former solar planets, proposals for space colonies and the consequent technical and ethical issues.

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.

There are specific UFO cases for which everyone should have a basic knowledge. Over 10 of these most important sightings and topics, occurring since 1945, model history with supported technical data, facts, and images supplying necessary information for those delving into the great mysteries of the universe. Historic background and possible explanations for experiences are offered and invite the reader to speculate and research further. Explore the following cases: UFOs over Germany, the Soviet Union, and the United States; sightings by pilots and the secret of the Black Triangle; the Roswell Incident and Area 51; the case of Betty Cash and Vicki Landrum; Rendlesham; and more.This collection is intended to suggest and remind readers that perhaps we should put the firmly established worldview into question and not exclude the possibility that there is more between heaven and Earth than we believe we know today.

This book provides an introduction to the physics of interstellar gas in the Galaxy. It deals with the diffuse interstellar medium which supplies a complex environment for exploring the neutral gas content of a galaxy like the Milky Way and the techniques necessary for studying this non-stellar component. After an initial exposition of the phases of the interstellar medium and the role of gas in a spiral galaxy, the authors discuss the transition from atomic to molecular gas. They then consider basic radiative transfer and molecular spectroscopy with particular emphasis on the molecules useful for studying low-density molecular gas. Observational techniques for investigating the gas and the dust component of the diffuse interstellar medium throughout the electromagnetic spectrum are explored emphasizing results from the recent Herschel and Planck missions. A brief exposition on dust in the diffuse interstellar medium is followed by a discussion of molecular clouds in general and high-latitude molecular clouds in particular. Ways of calibrating CO observations with the molecular hydrogen content of a cloud are examined along with the dark molecular gas controversy. High-latitude molecular clouds are considered in detail as vehicles for applying the techniques developed in the book. Given the transient nature of diffuse and translucent molecular clouds, the role of turbulence in the origin and dynamics of these objects is examined in some detail. The book is targeted at graduate students or postdocs who are entering the field of interstellar medium studies.

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.

All over the world there are fantastic ruins and objects that cannot be explained by conventional history, archaeology or religion. In the ground-breaking Chariots of the Gods, Erich von Daniken provides answers to these questions...why do religious texts often refer to Gods who descend from fiery chariots? Why do modern space launch sites look like constructions on the plains of Nazca in Peru? Was God an astronaut? By looking at human history and the ruins of ancient civilisations with an open mind, Erich von Daniken offers a new solution to these eternal mysteries in Chariots of the Gods. Why, for instance, do the world's sacred books describe Gods who came down from the sky in fiery chariots and always promised to return? How could an ancient Sanskrit text contain an account which could only be of a journey in an alien craft? Compare photographs of American space centre launch sites to the constructions on the plains of Nazca in Peru. In order to understand the mysteries which Erich von Daniken has catalogued we must go back to these ancient relics with an open mind. We must call in the resources and experience of sciences other than archaeology. Chariots of the Gods is a provocative attempt to explain some of the universe's most interesting mysteries. Erich von Daniken has spent a lifetime gathering evidence to prove that, before the dawn of recorded history, our ancestors were visited by an alien race. Erich von Daniken was responsible for popularising the ancient astronaut hypothesis of human development. Orthodox historians have been sceptical but a vast public have been drawn to his ideas by instinctive interest and wonder. His 26 books have sold over 60 million copies in over 40 languages.

Los hechos que narro en este libro, ocurrieron en Mayo del 2006. Fueron tan trascendentales, que necesite hasta octubre de ese mismo ano, para ordenar mi mente, y escribirlos. He demorado hasta el 2011 para su divulgacion, porque pense muchas veces que nadie los creeria, y no debia por ello hablar de eso. pero la importancia de este "encuentro cercano" con Aliens, y el fabuloso viaje que di en una de sus naves, requieren que yo cumpla el mandato que se me encomendo El libro consta de 16 capitulos, prologo, epilogo y un breve vocabulario. Y creo que su narrativa es sencilla y apasionante. No pienso que todo el mundo va a creerlo, pero si insto que todo aquel que lo lea, -crea o no en aliens-, reflexione sobre una verdad ineludible: Ellos estan aqui, y no es para hacernos ningun mal, sino todo lo contrario.Nuestro especie esta en grave peligro, y cada uno de nosotros debe tener conciencia de eso, y hacer su parte para ayudar a cuidar el mundo donde habitamos Por muy dificil que se les haga creer lo que aqui van a leer, piensen que para mi tambien lo fue, y por eso me costo tiempo divulgarlo. Espero que mediten en todo esto, y sepan la verdad, pues lo objetivo de cada hecho transcendental no es creerlo o no, sino analizarlo, interiorizarlo, y cambiar nuestra postura en la vida diaria, haciendo algo cada dia para que nuestros semejantes menos favorecidos, y el suelo donde habitamos, -llamado Tierra-, puedan continuar su ciclo de vida para las generaciones que nos sucederan.

"Brown argues convincingly that alien abduction stories speak to several key issues in our culture, from environmentalism to changing ideas about reproduction. Extending far beyond textual readings, she instead tells the stories of individual people, treating them with respect, but with a critical lens as well. Her analysis of the role of 'experts' in alien abduction-their power and the misuses of that power-is utterly compelling."
--Melani McAlister, George Washington University

aBrownas brilliant study is so much more than a book about alien abduction--it is a flesh-and-blood inquiry into the nature of belief in a technologically advanced society.a
--Andrew Ross, author of "Fast Boat to China"

Since its emergence in the 1960s, belief in alien abduction has saturated popular culture, with the ubiquitous image of the almond-eyed alien appearing on everything from bumper stickers to bars of soap. Drawing on interviews with alleged abductees from the New York area, Bridget Brown suggests a new way for people to think about the alien phenomenon, one that is concerned not with establishing whether aliens actually exist, but with understanding what belief in aliens in America may tell us about our changing understanding of ourselves and our place in the world.

They Know Us Better Than We Know Ourselves looks at how the belief in abduction by extraterrestrials is constituted by and through popular discourse and the images provided by print, film, and television. Brown contends that the abduction phenomenon is symptomatic of a period during which people have come to feel increasingly divested of the ability to know whatis real or true about themselves and the world in which they live. The alien abduction phenomenon helps us think about how people who feel left out create their own stories and fashion truths that square with their own experience of the world.
