The "New York Times" bestseller about the strange history of NASA and its cover-ups regarding its origins and extraterrestrial architecture found on the moon and Mars is even more interesting in its new edition.

Authors Richard C. Hoagland and Mike Bara include a new chapter about the discoveries made by ex-Nazi scientist and NASA stalwart Wernher von Braun regarding what he termed "alternate gravitational solutions," or the rewriting of Newtonian physics into hyperdimensional spheres.

Completely revised and updated, this new edition provides a readable, beautifully illustrated journey through world cultures and the vibrant array of sky mythology, creation stories, models of the universe, temples and skyscrapers that each culture has created to celebrate and respond to the power of the night sky. Sections on the archaeoastronomy of South Asia and South East Asia have been expanded, with original photography and new research on temple alignments in Southern India, and new material describing the astronomical practices of Indonesia, Malaysia and other Southeast Asian countries. Beautiful photographs of temples in India and Asia have been added, as well as new diagrams explaining the alignment of these structures and the astronomical underpinnings of temples within the Pallava and Chola cultures. From new fieldwork in the Four Corners region of North America, Dr. Penprase has included accounts of Pueblo skywatching and photographs of ceremonial kivas that help elucidate the rich astronomical knowledge of the Pueblo people. The popular "Archaeoastronomy of Skyscrapers" section of the book has been updated as well, with new interpretations of skyscrapers in Indonesia, Taiwan and China.With the rapid pace of discovery in astronomy and astrophysics, entirely new perspectives are emerging about dark matter, inflation and the future of the universe. The Power of Stars puts these discoveries in context and describes how they fit into the modern perspective of cosmology, which has arisen from the universal human response to the sky that has inspired both ancient and modern cultures.

This unique book presents a historical and philatelic survey of Earth exploration from space. It covers all areas of research in which artificial satellites have contributed in designing a new image of our planet and its environment: the atmosphere and ionosphere, the magnetic field, radiation belts and the magnetosphere, weather, remote sensing, mapping of the surface, observation of the oceans and marine environments, geodesy, and the study of life and ecological systems. Stamping the Earth from Space presents the results obtained with the thousands of satellites launched by the two former superpowers, the Soviet Union and the United States, and also those of the many missions carried out by the ESA, individual European countries, Japan, China, India, and the many emerging space nations. Beautifully illustrated, it contains almost 1100 color reproductions of philatelic items. In addition to topical stamps and thematic postal documents, the book provides an extensive review of astrophilatelic items. The most important space missions are documented through event covers and cards canceled at launch sites, tracking stations, research laboratories, and mission control facilities.

A special new edition of Apollo 13 Manual, published to coincide with the 50th Anniversary of the Moon mission launched in April 1970, which very nearly turned into a catastrophe. New content includes an expanded look at what was learned from the analysis of the problems that precipitated the crisis, and how these lessons affected the future space programme, and also a look at the worldwide reaction to the crisis, as the the international community held its breath. This Haynes Manual tells the story of the complex technical challenges involved in returning the crippled spacecraft safely to Earth, explained in detail by an expert author who was there through it all in Mission Control during the six-day flight. It is also the story of three very special heroes, the crew members of Apollo 13: Jim Lovell, Jack Swigert and Fred Haise.

Imagining Outer Space makes a captivating advance into the cultural history of outer space and extraterrestrial life in the European imagination. How was outer space conceived and communicated? What promises of interplanetary expansion and cosmic colonization propelled the project of human spaceflight to the forefront of twentieth-century modernity? In what way has West-European astroculture been affected by the continuous exploration of outer space? Tracing the thriving interest in spatiality to early attempts at exploring imaginary worlds beyond our own, the book analyzes contact points between science and fiction from a transdisciplinary perspective and examines sites and situations where utopian images and futuristic technologies contributed to the omnipresence of fantasmatic thought. Bringing together state-of-the-art work in this emerging field of historical research, the volume breaks new ground in the historicization of the Space Age.

Are humans a galactic oddity, or will complex life with human abilities develop on planets with environments that remain habitable for long enough? In a clear, jargon-free style, two leading researchers in the burgeoning field of astrobiology critically examine the major evolutionary steps that led us from the distant origins of life to the technologically advanced species we are today. Are the key events that took life from simple cells to astronauts unique occurrences that would be unlikely to occur on other planets? By focusing on what life does - it's functional abilities - rather than specific biochemistry or anatomy, the authors provide plausible answers to this question. Systematically exploring the various pathways that led to the complex biosphere we experience on planet Earth, they show that most of the steps along that path are likely to occur on any world hosting life, with only two exceptions: One is the origin of life itself - if this is a highly improbable event, then we live in a rather "empty universe". However, if this isn't the case, we inevitably live in a universe containing a myriad of planets hosting complex as well as microbial life - a "cosmic zoo". The other unknown is the rise of technologically advanced beings, as exemplified on Earth by humans. Only one technological species has emerged in the roughly 4 billion years life has existed on Earth, and we don't know of any other technological species elsewhere. If technological intelligence is a rare, almost unique feature of Earth's history, then there can be no visitors to the cosmic zoo other than ourselves. Schulze-Makuch and Bains take the reader through the history of life on Earth, laying out a consistent and straightforward framework for understanding why we should think that advanced, complex life exists on planets other than Earth. They provide a unique perspective on the question that puzzled the human species for centuries: are we alone?

Michael Swanson's online discussions with literally thousands of NexStar owners made it clear that there was a desperate need for a book such as this - one that provides a complete, detailed guide to buying, using and maintaining NexStar telescopes. Although this book is highly comprehensive, it is suitable for beginners - there is a chapter on "Astronomy Basics" - and experts alike. Celestron's NexStar telescopes were introduced in 1999, beginning with their first computer controlled "go to" model, a 5-inch. More models appeared in quick succession, and Celestron's new range made it one of the two dominant manufacturers of affordable "go to" telescopes.

This book journeys into one of the most fascinating intellectual adventures of recent decades - understanding and exploring the final fate of massive collapsing stars in the universe. The issue is of great interest in fundamental physics and cosmology today, from both the perspective of gravitation theory and of modern astrophysical observations. This is a revolution in the making and may be intimately connected to our search for a unified understanding of the basic forces of nature, namely gravity that governs the cosmological universe, and the microscopic forces that include quantum phenomena. According to the general theory of relativity, a massive star that collapses catastrophically under its own gravity when it runs out of its internal nuclear fuel must give rise to a space-time singularity. Such singularities are regions in the universe where all physical quantities take their extreme values and become arbitrarily large. The singularities may be covered within a black hole, or visible to faraway observers in the universe. Thus, the final fate of a collapsing massive star is either a black hole or a visible naked singularity. We discuss here recent results and developments on the gravitational collapse of massive stars and possible observational implications when naked singularities happen in the universe. Large collapsing massive stars and the resulting space-time singularities may even provide a laboratory in the cosmos where one could test the unification possibilities of basic forces of nature.

Choosing and Using a Refracting Telescope has been written for the many amateur astronomers who already own, or are intending to purchase, a refracting telescope - perhaps to complement their existing arsenal of larger reflecting telescopes - or for the specialist who requires a particular refractor for serious astronomical applications or nature studies. Four hundred year ago, during the winter of 1609, a relatively unknown Italian scientist, Galileo Galilei designed a spyglass with two crude lenses and turned it skyward. Since then, refractors have retained their dominance over all types of reflector in studies of the Moon, planets and double stars because of the precision of their optics and lack of a central obstruction in the optical path, which causes diffraction effects in all commercially-made reflectors. Most mature amateur astronomers got started with a 60mm refractor, or something similar. Thirty years ago, there was little choice available to the hobbyist, but in the last decade long focus crown-flint achromats have moved aside for some exquisitely crafted apochromatic designs offered by leading commercial manufacturers. There has been a huge increase in the popularity of these telescopes in the last few years, led by a significant increase in the number of companies (particularly, William Optics, Orion USA, StellarVue, SkyWatcher and AstroTech) who are now heavily marketing refractors in the amateur astronomical magazines. In Choosing and Using a Refracting Telescope, well-known observer and astronomy writer Neil English celebrates the remarkable history and evolution of the refracting telescope and looks in detail at the instruments, their development and their use. A major feature of this book is the way it compares not only different classes of refractor, but also telescopes of each class that are sold by various commercial manufacturers. The author is perhaps uniquely placed to do this, having used and tested literally hundreds of different refracting telescopes over three decades. Because it includes many diverse subjects such as imaging with consumer-level digital cameras, imaging with webcams, and imaging with astronomical CCD cameras - that are not covered together in equal depth in any other single volume - Choosing and Using a Refracting Telescope could become the 'refractor bible' for amateur astronomers at all levels, especially those who are interested in imaging astronomical objects of every class.

If you have ever wanted to understand the basic principles of astronomy and celestial movements, you should read this book. Using pictures of the sky observed from different places on Earth, as well as drawings of ancient astronomical methods and tools, Prof. Sun Kwok tells this story in an entertaining and fascinating way. Since the beginning of human civilization, people have wondered about the structure of the cosmos and our place in the Universe. More than 2,000 years ago, our ancestors knew that the seasons were unequal, the Earth was an unattached object floating in space, and stars existed that they could not see. From celestial observations, they concluded that the Earth was round. Using simple tools and mathematics, ancient astronomers accurately determined the sizes of the Earth and Moon, the distance to the Moon, and the lengths of the months and year. With a clever device called the armillary sphere, Greek astronomers could predict the times of sunrise and sunset on any day of the year, at any place on Earth. They developed sophisticated mathematical models to forecast Mars' motions hundreds of years into the future. Find out how ancient observers achieved these remarkable feats. With minimal use of mathematics, this book retraces the footsteps of our ancestors, explains their intellectual journeys in simple terms, and explores the philosophical implications of these discoveries.

The Sun, which is our own star at the center of the Solar System, gives rise to all life on Earth and is the driver of photosynthesis in plants and the source of all food and energy for living things. As seen with the naked eye, the Sun appears as a static and quiet yellow disk in the sky. However, it is a stormy and ever-changing star that contributes much more than light and heat. For example, it is the source of the beautiful northern lights and can affect our technology-based society in many ways. Our Explosive Sun: A Visual Feast of our Source of Light and Life is a great introduction to the Sun for general readers as well as scientists who are not solar physicists. The book presents the basic properties of the Sun, describes how it has fascinated humans throughout history, and shows how it influences our current technologies. The book includes a large number of illustrations and video materials for SpringerExtras, along with a PowerPoint presentation that provides a useful resource for teachers and lectures.

When astronomers today look up at the night sky they picture a spectacular and infinite universe--full of pulsars, quasars, and black holes and ruled by arcane laws of space and time. Once, ancient astronomers looked up and saw only points of light tracing calm movements across the heavens. But they too were moved to wonder about the meaning of what they saw. In Astronomy through the Ages, Sir Robert Wilson tells the story of how our understanding of the universe has evolved through history--of how the sedate and stable star field of ancient times has been replaced by the vast and explosive universe we know today. Wilson, one of the most distinguished astronomers of the twentieth century, begins by tracing the astronomical studies of the ancient Babylonians, Egyptians, and Greeks and reviews important early contributions from India, China, and the Islamic world. He explains the development of the sun-centered model of the universe in Renaissance Europe. He then tells how the development of the telescope, photography, and spectroscopy pushed back the limits of the observable universe and eventually brought astronomy into the twentieth century. Finally, he describes the rapid advances in radio and space astronomy and other methods over the past fifty years that have ushered in a new "golden age" of astronomy. These advances have not only allowed observation of deep space but also enabled scientists to unlock the secrets of the universe itself from its origin to its possible fate. Wilson himself has played an important role in these discoveries as the developer of one of the most successful astronomical satellites ever launched, the International Ultraviolet Explorer. While focusing on the human side of astronomical discovery, Wilson also provides readers with a basic understanding of difficult concepts, explaining relativity and quantum mechanics without using technical language or mathematics. Remarkable in its scope and clarity,Astronomy through the Ages provides an accessible view of historical discoveries and modern advances and shows why excitement about astronomy is even greater today than when Galileo first gazed in wonder at the rings of Saturn. Originally published in 1998. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The aim of this book (and subsequent volumes issued annually) is to provide an annual astronomy review suitable for the popular science level reader. It will be published every year in September in a format suitable for an appeal to the Christmas market. The book will cover all major astronomical news on topics beyond the Solar System and place them in the context of the longer term goals that astronomers and astrophysicists around the world are aiming for. The target is to capture the excitement of modern astronomical research enabling reader to stay up-to-date with its rapid pace and development.

This book recounts the epic saga of how we as human beings have come to understand the Solar System. The story of our exploration of the heavens, Peter Bond reminds us, began thousands of years ago, with the naked-eye observations of the earliest scientists and philosophers. Over the centuries, as our knowledge and understanding inexorably broadened and deepened, we faltered many times, frequently labored under misconceptions, and faced seemingly insurmountable obstacles to understanding. Yet, despite overwhelming obstacles, a combination of determined observers, brilliant thinkers, courageous explorers, scientists and engineers has brought us, particularly over the last five decades, into a second great age of human discovery. At our present level of understanding, some fifty years into the Space Age, the sheer volume of images and other data being returned to us from space has only increased our appetite for more and more detailed information about the planets, moons, asteroids, and comets of the Solar System. Taking a much-needed overview of how we now understand these "distant worlds" in our cosmic neighborhood, Bond not only celebrates the extraordinary successes of planetary exploration, but reaffirms an important truth: For seekers of knowledge, there will always be more to explore. An astonishing saga of exploration... In this much-needed overview of "where we stand today," Peter Bond describes the achievements of the astronomers, space scientists, and engineers who have made the exploration of our Solar System possible. A clearly written and compelling account of the Space Age, the book includes: * Dramatic accounts of the daring, resourcefulness, and ferocious competitive zeal of renowned as well as almost-forgotten space pioneers. * Clear explanations of the precursors to modern astronomy, including how ancient natural philosophers and observers first took the measure of the heavens. * More than a hundred informative photographs, maps, simulated scenarios, and technical illustrations--many of them in full color. * Information-dense appendices on the physical properties of our Solar System, as well as a comprehensive list of 50 years of Solar System missions. Organized into twelve chapters focused on the objects of our exploration (the individual planets, our Moon, the asteroids and comets), Bond's text shows how the great human enterprise of space exploration may on occasion have faltered or wandered off the path, but taken as a whole amounts to one of the great triumphs of human civilization.

The idea of transforming alien worlds has long been a literary backdrop for science fiction writers, and many a make-believe planet has succumbed to the actions of direct manipulation and the indomitable grinding of colossal machines. Indeed, there is something both liberating and humbling about the notion of tra- forming another world; it is the quintessential eucatastrophy espoused by J. R. R. Tolkien, the catastrophe that ultimately brings about a better world. When oxygen was first copiously produced by cyanobacterial activity on the Earth some three billion years ago, it was an act of extreme chemical pollution and a eucatastrophy. The original life-nurturing atmosphere was (eventually) changed f- ever, but an atmosphere that could support advanced life forms came about.

This biography summarizes the seminal contributions to auroral and space science of Carl Stormer (1874 - 1957). He was the first to develop precise photographic methods to calculate heights and morphologies of diverse auroral forms during four solar cycles. Stormer independently devised numerical techniques to determine the trajectories of high-energy charged particles allowed and forbidden in the Earth's magnetic field. His theoretical analyses explained cosmic ray access to the upper atmosphere, 20 years before they were identified by other scientists. Stormer's crowning achievement, "The Polar Aurora," published when he was 81 years old, stands to this day as a regularly cited guide in graduate-level courses on space physics. The authors present the life of this prodigious scientist in relation to the cultural life of early 20th century in Norway and to the development of the space sciences in the post-Sputnik era.

Indulge your curiosity with this humorous and fascinating book that demystifies the surprising myths about space.

In the latest book from the Everything You Know is Wrong series, Matt Brown brings you a compendium of amazing facts about our planet, the universe, and everything in between! Thanks to popular sci-fi films and TV shows, there have been many misconceptions about the cosmos – from travelling through worm-holes to blowing up asteroids. In Everything You Know About Space is Wrong, you'll find a plethora of myths, legends and misquotes that have shaped the way you view the universe today. Think that the vacuum of space would make your blood boil and your head explode? It won't, and there have been people who have survived without wearing a suit in space. Think that astronauts float in space because there is zero-gravity? They're actually constantly falling towards the Earth. Think that the colour of space is black? It's actually predominantly green.

Chock-full of facts about the cosmos, how it works (and how it doesn't!), this illuminating book will guide you through the mine of misinformation to answer such questions as whether we will meet aliens in our lifetime (SETI predicts we'll find evidence of ET by 2040!), what happens in the centre of the black hole, and why Mercury is not the hottest planet in the solar system. Discovering untruths about popular science, Everthing You Know About Space is Wrong provides a hugely entertaining insight into our universe.

Although most people have some knowledge of the essential structure of the Solar System, few are familiar with the large and varied array of objects that travel with and between the planets in their journeys around the Sun. Imaging techniques from Earth continue to improve, while missions such as Voyager, Galileo and the Hubble Space Telescope have yielded many excellent images. Most significantly of all, several missions in recent years have shown a huge diversity of objects in close-up for the first time. The book will take advantage of the rich pool of images that is available, to tell a story of the Solar System that has not been told before. Smaller Bodies will be a collection of approximately 72 stunning images, all from the public domain but not hitherto gathered into a coherent collection, with supporting text and graphics. Each main image will be accompanied by a graphic showing the location in the Solar System of the featured object. All of these graphics will be based in a simple template providing a simple representation of the Solar System. Text will not be extensive, allowing page design to have a high priority, and will be of three kinds. 'Main text' (approximately 200 words) will provide stimulating introduction and some key ideas. Text headed 'The object(s)' (25-75 words) will provide a brief description of featured objects. Text headed 'The image' (25-75 words) will provide information on the source of the image and some brief technical information where required (such as in describing use of false color). The book is intended for anybody who lives in solar orbit and takes a general interest in the solar neighborhood.

A gripping first-person account of how scientists came to understand our universe's mysterious structure J. Richard Gott was among the first cosmologists to propose that the structure of our universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies-a magnificent structure now called the "cosmic web" and mapped extensively by teams of astronomers. Here is his gripping insider's account of how a generation of undaunted theorists and observers solved the mystery of the architecture of our cosmos. The Cosmic Web begins with modern pioneers of extragalactic astronomy, such as Edwin Hubble and Fritz Zwicky. It goes on to describe how, during the Cold War, the American school of cosmology favored a model of the universe where galaxies resided in isolated clusters, whereas the Soviet school favored a honeycomb pattern of galaxies punctuated by giant, isolated voids. Gott tells the stories of how his own path to a solution began with a high-school science project when he was eighteen, and how he and astronomer Mario Juric measured the Sloan Great Wall of Galaxies, a filament of galaxies that, at 1.37 billion light-years in length, is one of the largest structures in the universe. Drawing on Gott's own experiences working at the frontiers of science with many of today's leading cosmologists, The Cosmic Web shows how ambitious telescope surveys such as the Sloan Digital Sky Survey are transforming our understanding of the cosmos, and how the cosmic web holds vital clues to the origins of the universe and the next trillion years that lie ahead.

The First Edition of The Sun from Space, completed in 1999, focused on the early accomplishments of three solar spacecraft, SOHO, Ulysses, and Yohkoh, primarily during a minimum in the Sun's 11-year cycle of magnetic activity. The comp- hensive Second Edition includes the main ndings of these three spacecraft over an entire activity cycle, including two minima and a maximum, and discusses the signi cant results of six more solar missions. Four of these, the Hinode, RHESSI, STEREO, and TRACE missions were launched after the First Edition was either nished or nearly so, and the other two, the ACE and Wind spacecraft, extend our investigations from the Sun to its varying input to the Earth. The Second Edition does not contain simple updates or cosmetic patch ups to the material in the First Edition. It instead contains the relevant discoveries of the past decade, integrated into chapters completely rewritten for the purpose. This provides a fresh perspective to the major topics of solar enquiry, written in an enjoyable, easily understood text accessible to all readers, from the interested layperson to the student or professional.

This unique volume by two renowned astrophotographers unveils the science and history behind 100 of the most significant astronomical images of all time. The authors have carefully selected their list of images from across time and technology to bring to the reader the most relevant photographic images spanning all eras of modern astronomical history. Based on scientific evidence today we have a basic notion of how Earth and the universe came to be. The road to this knowledge was paved with 175 years of astronomical images acquired by the coupling of two revolutionary technologies - the camera and telescope. With ingenuity and determination humankind would quickly embrace these technologies to tell the story of the cosmos and unravel its mysteries. This book presents in pictures and words a photographic chronology of our aspiration to understand the universe. From the first fledgling attempts to photograph the Moon, planets, and stars to the marvels of orbiting observatories that record the cosmos at energies beyond the range of human vision, astronomers have always relied on images to "break through" to the next level of understanding. A subset of these breakthrough images has profound significance in documenting some of the greatest milestones in modern astronomy.

This is the story of the astronomer Milton La Salle Humason, whose career was integral to developing our understanding of stellar and universal evolution and who helped to build the analytical basis for the work of such notable astronomers and astrophysicists as Paul Merrill, Walter Adams, Alfred Joy, Frederick Seares, Fritz Zwicky, Walter Baade and Edwin Hubble. Humason's unlikely story began on the shores of the Mississippi River in Winona, Minnesota, in 1891 and led to the foot of Mount Wilson outside Los Angeles, California, twelve years later. It is there where he first attended summer camp in 1903 and was captivated by its surroundings. The mountain would become the backdrop for his life and career over the next six decades as he helped first build George Ellery Hale's observatory on the summit and then rose to become one of that institution's leading figures through the first half of the twentieth century. The story chronicles Humason's life on Mount Wilson, from his first trip to the mountain to his days as a muleskinner, leading teams of mules hauling supplies to the summit during the construction of the observatory, and follows him through his extraordinary career in spectroscopy, working beside Edwin Hubble as the two helped to reconstruct our concept of the universe. A patient, knowledgeable and persistent observer, Humason was later awarded an honorary doctorate for his work, despite having no formal education beyond the eighth grade. His skill at the telescope is legendary. During his career he photographed the spectra of stars, galaxies and other objects many thousands of times fainter than can be seen with the naked eye and pushed the boundary of the known universe deeper into space than any before him. His work, which included assisting in the formulation of Hubble's Law of redshifts, helped to set the field of cosmology solidly on its foundation. Milton Humason was one of the most charismatic characters in science during the first half of the 20th century. Uneducated, streetwise, moonshining, roguish, humble and thoroughly down to earth, he rose by sheer chance, innate ability and incredible will to become the leading deep space observer of his day. "The Renaissance man of Mount Wilson," as Harlow Shapley once referred to him, Humason's extraordinary life reminds us that passion and purpose may find us at any moment.

Oceans were long thought to exist in all corners of the Solar System, from carbonated seas percolating beneath the clouds of Venus to features on the Moon's surface given names such as "the Bay of Rainbows" and the "Ocean of Storms." With the advent of modern telescopes and spacecraft exploration these ancient concepts of planetary seas have, for the most part, evaporated. But they have been replaced by the reality of something even more exotic. For example, although it is still uncertain whether Mars ever had actual oceans, it now seems that a web of waterways did indeed at one time spread across its surface. The "water" in many places in our Solar System is a poisoned brew mixed with ammonia or methane. Even that found on Jupiter's watery satellite Europa is believed similar to battery acid. Beyond the Galilean satellites may lie even more "alien oceans." Saturn's planet-sized moon Titan seems to be subject to methane or ethane rainfall. This creates methane pools that, in turn, become vast lakes and, perhaps, seasonal oceans. Titan has other seas in a sense, as large shifting areas of sand covering vast plains have been discovered. Mars also has these sand seas, and Venus may as well, along with oceans of frozen lava. Do super-chilled concoctions of ammonia, liquid nitrogen, and water percolate beneath the surfaces of Enceladus and Triton? For now we can only guess at the possibilities. 'Alien Seas' serves up part history, part current research, and part theory as it offers a rich buffet of "seas" on other worlds. It is organized by location and by the material of which various oceans consist, with guest authors penning specific chapters. Each chapter features new original art depicting alien seas, as well as the latest ground-based and spacecraft images. Original diagrams presents details of planetary oceans and related processes.
