Describes the branch of astronomy in which processes in the universe are investigated with experimental methods employed in particle-physics experiments. After a historical introduction the basics of elementary particles, Explains particle interactions and the relevant detection techniques, while modern aspects of astroparticle physics are described in a chapter on cosmology. Provides an orientation in the field of astroparticle physics that many beginners might seek and appreciate because the underlying physics fundamentals are presented with little mathematics, and the results are illustrated by many diagrams. Readers have a chance to enter this field of astronomy with a book that closes the gap between expert and popular level.

In The Search for Life on Other Planets, Jakosky offers a scientific foundation for thinking there may be life elsewhere in the Universe. Using the early history of the Earth and the conditions that would allow life to exist, he creates a sound, scientific foundation for the possibility of life on planets other than our own. Jakosky integrates the mechanics of planets and recent findings from our planetary exploration program to create a rich and accessible look at the likelihood of extraterrestrials and the possibility of life on other planets. His prose is authoritative but avoids technical jargon and is well illustrated throughout. For all those interested in understanding the scientific evidence for and likelihood of extraterrestrial life, this is the most comprehensive and readable book to date. Bruce Jakosky is active in spacecraft observations, and has been involved with the Viking, Solar Mesosphere Explorer, Clementine, Mars Observer, and Mars Global Surveyor missions. Currently, he teaches both undergraduate and graduate courses in terrestrial and planetary geology at the University of Colorado, Boulder.

The Believer is the weird and chilling true story of Dr. John Mack. This eminent Harvard psychiatrist and Pulitzer Prize-winning biographer risked his career to investigate the phenomenon of human encounters with aliens and to give credibility to the stupefying tales shared by people who were utterly convinced they had happened. Nothing in Mack's four decades of psychiatry had prepared him for the otherworldly accounts of a cross section of humanity including young children who reported being taken against their wills by alien beings. Over the course of his career his interest in alien abduction grew from curiosity to wonder, ultimately developing into a limitless, unwavering passion. Based on exclusive access to Mack's archives, journals, and psychiatric notes and interviews with his family and closest associates, The Believer reveals the life and work of a man who explored the deepest of scientific conundrums and further leads us to the hidden dimensions and alternate realities that captivated Mack until the end of his life.

Are we alone in the universe? If not, where is everybody? An engaging exploration of one of the most important unsolved problems in science. Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity-but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox-and finding extraterrestrials.

This book aims at providing a brief but broad overview of biosignatures. The topics addressed range from prebiotic signatures in extraterrestrial materials to the signatures characterising extant life as well as fossilised life, biosignatures related to space, and space flight instrumentation to detect biosignatures either in situ or from orbit. The book ends with philosophical reflections on the implications of life elsewhere. In the 15 chapters written by an interdisciplinary team of experts, it provides both detailed explanations on the nature of biosignatures as well as useful case studies showing how they are used and identified in ancient rocks, for example. One case study addresses the controversial finding of traces of fossil life in a meteorite from Mars. The book will be of interest not only to astrobiologists but also to terrestrial paleontologists as well as any reader interested in the prospects of finding a second example of life on another planet.

This book is the result of the work of the first international congress of the ArabGU (Arabian Geosciences Union) which took place in Algiers (Algeria) in February 2016. It presents research articles and review papers on geology of the North Africa and Arabian Middle East . It provides information to the public on various fields of earth sciences and encourages further research in this field in order to attract an international audience.

Centuries before the U.S. Air Force launched Project Blue Book or mysteries swirled around the enigmatic Area 51, the Puritans in 1639 witnessed a great light in the sky over Massachusetts. It was the first recorded sighting of an unidentified flying object. Now, sightings are so common they're not even front-page news, and the Air Force just released all the records from Project Bluebook.Despite all this, there remain sightings that cannot be easily explained. Are we being visited by another species? The Universe, it seems, is full of mystery. Tracing the strange history of UFO sightings in the region, Taryn Plumb presents the stories of sightings or events in each New England state. Many are unexplained sightings of strange objects or lights in the sky; and some tell the tales of alien encounters and even abductions. All will keep you glancing to the night sky, wondering what that was out of the corner of your eye.
