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.

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?

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.

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.

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 cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.

The first edition of 'Hubble's Universe' displayed 300 pages of high-resolution celestial portraits selected by bestselling astronomy writer Terence Dickinson from the initial 22 years of the Hubble Space Telescope's exploration of distant galaxies. With the telescope now at the apex of its imaging capabilities, this second edition adds another chapter with more than 36 completely new images, including the first publication of a four-page fold-out of the Andromeda Galaxy, the nearest spiral galaxy to Earth, revealing more than one million individual stars.Thanks to Dickinson's familiarity with Hubble's history and discoveries and his access to top Hubble scientists for insight and accuracy, the text includes facts and tidbits not found in any other book. Combined with 330 brilliant images, the clear, succinct and illuminating narrative brings to life the fascinating forces at work in the universe.

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.

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.

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.

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.

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.

Much of what is known about the universe came from the study of celestial shadows. This book looks in detail at the way eclipses and other celestial shadows have given us amazing insights into the nature of the objects in our solar system and how they are even helping us discover and analyze planets that orbit stars other than our Sun. A variety of eclipses, transits, and occultations of the mooons of Jupiter and Saturn, Pluto and its satellite Charon, asteroids and stars have helped astronomers to work out their dimensions, structures, and shapes - even the existence of atmospheres and structures of exoplanets. Long before Columbus set out to reach the Far East by sailing West, the curved shadow of the Earth on the Moon during a lunar eclipse revealed that we inhabit a round world, a globe. More recently, comparisons of the sunlit and Earthlit parts of the Moon have been used to determine changes in the Earth's brightness as a way of monitoring possible effects in cloud coverage which may be related to global warming. Shadows were used by the Greek mathematician Eratosthenes to work out the first estimate of the circumference of the Earth, by Galileo to measure the heights of the lunar mountains and by eighteenth century astronomers to determine the scale of the Solar System itself. Some of the rarest and most wonderful shadows of all are those cast onto Earth by the lovely "Evening Star" Venus as it goes between the Earth and the Sun. These majestic transits of Venus occur at most two in a century; after the 2012 transit, there is not a chance to observe this phenomenon until 2117, while the more common sweep of a total solar eclipse creates one of the most dramatic and awe-inspiring events of nature. Though it may have once been a source of consternation or dread, solar eclipses now lead thousands of amateur astronomers and "eclipse-chasers" to travel the globe in order to experience the dramatic view under "totality." These phenomena are among the most spectacular available to observers and are given their full due in Westfall and Sheehan's comprehensive study.

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.

As with the author's recent books Extreme Explosions and Under a Crimson Sun, the complex topic of star clusters is broken down and made accessible with clear links to other areas of astronomy in a language which the non-specialist can easily read and enjoy. The full range of topics are addressed regarding how star clusters are formed. Why is it some are dense conglomerates of stars while others are looser associations? Are the young, brilliant clusters seen in neighboring galaxies such as the Large Magellanic Cloud, M33 or M82 analogous to the ancient globulars seen in the Milky Way? How will these clusters change as their stars wane and die? More interestingly, how does living in a dense star cluster affect the fates of the stars and any attendant planets that accompany them? Star clusters form many of the most dazzling objects in the astronomers' catalogs. Many amateur astronomers are interested in exploring how these objects are created and what it would be like to live among these objects. From the historical views of how star clusters came about to the most recent assumptions about how stars within these clusters evolve, different strands of science, from observation to theory, are woven together into a compelling investigation specifically targeted at amateur astronomers.

With current technology, a voyage to Mars and back will take three years. That's a lot of time for things to go wrong. But sooner or later a commercial enterprise will commit itself to sending humans to Mars. How will the astronauts survive?

Questions like these, and hundreds of others, have been explored by science fi ction, but scant attention has been paid by those designing missions. Fortunately, the experience gained in polar exploration more than 100 years ago provides crews and mission planners with a framework to deal with contingencies and it is this that forms the core of this book. Why the parallels between polar and space exploration? Because polar exploration offers a better analogy for a Mars mission today than those invoked by the space community. Although astronauts are routinely compared to Lewis and Clark, Mars-bound astronauts will be closer in their roles to polar explorers. And, as much as space has been described as a New Frontier, Mars bears greater similarity to the polar regions, which is why so much can be learned from those who ventured there.

The year is 2130. The first-ever expedition is sent to Mercury to search for the cause of an unknown source of electromagnetic radiation that can destroy space ships passing by the planet. Thought to be inhospitable and lifeless, the surface of Mercury provides startling surprises for the crew that endanger their lives and challenge their established notions of what it means to be a sentient being. And some of the crew members have their own separate agendas ...The scientific appendix at the end of the book introduces readers to the wondrous world of Mercury and how it has been portrayed in literary fiction up to the present time. The author then uses scientific literature to present a concept of life that is not based on carbon chemistry or the need for water. There is also a discussion of consciousness based on electromagnetic wave theory.

This book gives a detailed introduction to the thousands and thousands of smaller bodies in the solar system. Written for interested laymen, amateur astronomers and students it describes the nature and origin of asteroids, dwarf planets and comets, and gives detailed information about their role in the solar system. The author nicely reviews the history of small-world-exploration and describes past, current and future space craft missions studying small worlds, and presents their results. Readers will learn that small solar system worlds have a dramatically different nature and appearance than the planets. Even though research activity on small worlds has increased in the recent past many of their properties are still in the dark and need further research.

Diamond Worlds, Super Earths, Pulsar Planets and the New Search for Life Beyond our Solar System

This book, written for a general readership, reviews and explains the three-body problem in historical context reaching to latest developments in computational physics and gravitation theory. The three-body problem is one of the oldest problems in science and it is most relevant even in today's physics and astronomy. The long history of the problem from Pythagoras to Hawking parallels the evolution of ideas about our physical universe, with a particular emphasis on understanding gravity and how it operates between astronomical bodies. The oldest astronomical three-body problem is the question how and when the moon and the sun line up with the earth to produce eclipses. Once the universal gravitation was discovered by Newton, it became immediately a problem to understand why these three-bodies form a stable system, in spite of the pull exerted from one to the other. In fact, it was a big question whether this system is stable at all in the long run. Leading mathematicians attacked this problem over more than two centuries without arriving at a definite answer. The introduction of computers in the last half-a-century has revolutionized the study; now many answers have been found while new questions about the three-body problem have sprung up. One of the most recent developments has been in the treatment of the problem in Einstein's General Relativity, the new theory of gravitation which is an improvement on Newton's theory. Now it is possible to solve the problem for three black holes and to test one of the most fundamental theorems of black hole physics, the no-hair theorem, due to Hawking and his co-workers.
