This volume provides a detailed snapshot of the state-of-the-art of the field fifteen years after the first extrasolar planet discovery announcement. The major review articles and contributed papers allow for vibrant discussions and confrontations between theory and observations. Datasets of the highest quality, innovative numerical tools and increasingly sophisticated theoretical models show the impressive progress being made in our understanding of planet formation and evolution, heralding the era of 'comparative planetology' as a new, expanding interdisciplinary research field. IAU S276 also examines the strategic planning exercises of both the science community and space agencies and ongoing preparations and developments of future ground-based and space-borne observatories devoted to the detection and characterization of extrasolar planets. This stimulating volume constitutes an important reference for both young scientists and seasoned researchers, who will contribute to the frontier of research in the field during the next decade.

Exactly what is beyond Pluto? Why, in the last ten years, has the Solar System more than doubled in size? For the first time, in almost two centuries, an entirely new population of planetary objects has been found that may well explain these two questions. This newly discovered realm of minor planets, now known as the "Kuiper Belt," has reconceptualized our understanding of how the Solar System was formed and has finally given ontological explanations for the enigmatic outer planet Pluto. Beyond Pluto is the fascinating story of how a group of theoretical physicists decided that there must be a population of unknown bodies beyond Pluto and how a small band of astronomers set out to find them. Acclaimed scientist John K. Davies recounts how they predicted the existence of these planetary bodies, how they were eventually discovered, and how Pluto was named. In addition, Davies provides biographies of the astronomers who discovered these new worlds and information on the telescopes they used. John K. Davies is a support scientist for the UK Infrared Telescope (UKIRT) atop the dormant volcano Mauna Kea in Hawaii. He holds PhDs in chemistry and astronomy, discovered six comets while teaching at Leicester University in the UK, and was a member of the ISO-CAM team at the Royal Observatory in Edinburgh, Scotland. He has contributed to magazines such as Astronomy, New Scientist, Sky & Telescope, and Space. In 2000, a small main asteroid belt was named Johndavies in recognition of his numerous contributions to astronomy.

William Parsons (1800 67), third Earl of Rosse, was responsible for building in 1845 the largest telescope of his time, nicknamed the 'Leviathan'. It enabled the Earl to make unprecedented astronomical discoveries, including the discovery of the spiral nature of galaxies. Rosse (then Lord Oxmantown) began publishing scientific papers on telescopes in 1828, and for the rest of his life made regular contributions to scientific journals in Ireland, England and Scotland. He served as President of the British Association for the Advancement of Science in 1843, and of the Royal Society from 1848 to 1854, and his addresses to those societies are also included in this collection. Edited by his younger son, the engineer Sir Charles Parsons (1854 1931) and published in 1926, these papers show the wide range of the Earl's interests, from astronomy and telescopes to ancient bronze artefacts and the use of iron in shipbuilding.

J. P. Nichol (1804-59), astronomer and political economist, was Regius Professor of Astronomy at the University of Glasgow. He brought astronomy to a non-scientific audience through his enthusiastic public lectures and astronomy books. His works include the popular Views of the Architecture of the Heavens (1837; also reissued in this series) in which he supported the nebular hypothesis, which in modified form is the model of star formation most widely accepted today. Neptune was (in 1846) the first planet to be discovered by mathematical prediction rather than empirical observation, and in this book, first published in 1855, Nichol describes that discovery to a lay readership. Part 1 is an exposition of the then current view of the solar system and the research and discoveries which led to that view; Part 2 is dedicated to Neptune; while the third part explains the controversies over the planet's discovery.

An entertaining, often surprising cultural examination of Earth's moon, through history, science, and literature, from ancient times to the present Werewolves and Wernher von Braun, Stonehenge and the sex lives of sea corals, aboriginal myths, and an Anglican bishop: In his new book, Moon, Bernd Brunner weaves variegated information into an enchanting glimpse of Earth's closest celestial neighbor, whose mere presence inspires us to wonder what might be "out there." Going beyond the discoveries of contemporary science, Brunner presents an unusual cultural assessment of our complex relationship with Earth's lifeless, rocky satellite. As well as offering an engaging perspective on such age-old questions as "What would Earth be like without the moon?" Brunner surveys the moon's mythical and religious significance and provokes existential soul-searching through a lunar lens, inquiring, "Forty years ago, the first man put his footprint on the moon. Will we continue to use it as the screen onto which we cast our hopes and fears?" Drawing on materials from different cultures and epochs, Brunner walks readers down a moonlit path illuminated by more than seventy-five vintage photographs and illustrations. From scientific discussions of the moon's origins and its "chronobiological" effects on the mating and feeding habits of animals to an illuminating interpretation of Bishop Francis Godwin's 1638 novel The Man in the Moone, Brunner's ingenious and interdisciplinary explorations recast a familiar object in an entirely original and unforgettable light and will change the way we view the nighttime sky.

Recent discoveries of planet-like objects circling other sun-like stars have stirred enormous interest in what other planets may exist in the universe, and whether they could support intelligent life. This book takes us into the midst of this search for extrasolar planets. Unlike other books, it focuses on the people behind the searches -- many known personally by the author -- and the extraordinary technology that is currently on the drawing boards. The author is an experienced, award-winning science journalist who was previously technology correspondent for the Financial Times of London. He has written on many topics in astronomy and astrobiology in over 35 different newspapers and magazines worldwide.

Research into the geological processes operating on Mars relies on interpretation of images and other data returned by unmanned orbiters, probes and landers. Such interpretations are based on our knowledge of processes occurring on Earth Terrestrial analog studies therefore play an important role in understanding the geological features observed on Mars. This 2007 book presents direct comparisons between locales on Earth and Mars, and contains contributions from leading planetary geologists to demonstrate the parallels and differences between these two neighboring planets. Mars is characterized by a wide range of geological phenomena that also occur on Earth, including tectonic, volcanic, impact cratering, eolian, fluvial, glacial and possibly lacustrine and marine processes. The book provides terrestrial analogs for data sets from Mars Global Surveyor, Mars Odyssey, Mars Exploration Rovers and Mars Express, and will therefore be a key reference for students and researchers of planetary science.

The book begins with a historical review of four major theories for the origin of the Solar System in particular, or of planets in general, which highlight the major problems that need to be solved by any plausible theory. In many theories, including that which form the major theme of this book, the formation of planets and stars is intimately linked, so four chapters are devoted to the processes that can be described as the birth, life and death of stars.Recent observations that have revealed the existence of planets around many Sun-like stars are described in detail, followed by a clear exposition of the Capture Theory for the origin of planets. Many aspects of this theory are illustrated with sophisticated computer modelling that convincingly demonstrates the plausibility of the theory. The Capture Theory is in complete accord with all observations, including the estimate it gives for the proportion of Sun-like stars with planets. It is the only theory that sits comfortably with all present observational and theoretical constraints.The general theory of planet formation does not explain the detailed structure of the Solar System. An early postulated collision of two major planets is shown to explain many disparate features of the Solar System - the nature of the terrestrial planets, surface features of the Moon and its relationship with Earth, asteroids, comets and dwarf planets, the relationship between Neptune, Triton and Pluto and the characteristics of meteorites, including the isotopic anomalies found in them. The postulate of a planetary collision is given support by a 2009 NASA observation of the residue of such an event around a distant young star.

Humans have long thought that planetary systems similar to our own should exist around stars other than the Sun, yet the search for planets outside our Solar System has had a dismal history of discoveries that could not be confirmed. However, this all changed in 1995, after which astonishing progress can be seen in this field; we now know of more than 200 extrasolar planets. These findings mark crucial milestones in the search for extraterrestrial life - arguably one of the most intriguing endeavors of modern science. These proceedings from the 2005 Space Telescope Science Institute Symposium on Extrasolar Planets explore one of the hottest topics in astronomy. Discussions include the Kepler mission, observational constraints on dust disk lifetimes and the implications for planet formation, and gravitational instabilities in protoplanetary disks. With review papers written by world experts in their fields, this is an important resource on extrasolar planets.

This revised edition places a unique emphasis on all the new results from ground-based, satellites and space missions -- detection of molecule H2 and prompt emission lines of OH for the first time; discovery of X-rays in comets; observed diversity in chemical composition among comets; the puzzle of the constancy of spin temperature; the well-established mineralogy of cometary dust; extensive theoretical modeling carried out for understanding the observed effects; the similarity in the mineralogy of dust in circumstellar shell of stars, comets, meteorites, asteroids and IDPs, thus indicating the generic relationship between them.

It is known that large asteroids and comets can collide with the Earth with severe consequences. Although the chances of a collision in a person's lifetime are small, collisions are a random process and could occur at any time. This book, which was first published in 2004, collects the latest thoughts and ideas of scientists concerned with mitigating the threat of hazardous asteroids and comets. It reviews knowledge of the population of potential colliders, including their numbers, locations, orbits, and how warning times might be improved. The structural properties and composition of their interiors and surfaces are reviewed, and their orbital response to the application of pulses of energy is discussed. Difficulties of operating in space near, or on the surface of, very low mass objects are examined. The book concludes with a discussion of the problems faced in communicating the nature of the impact hazard to the public.

Chondrules in primitive meteorites have excited and challenged scientists since they were first described nearly 200 years ago. Chondrules were made by some pervasive process in the early solar system that formed melted silicate droplets. This 1996 text was the first comprehensive review of chondrules and their origins since a consensus developed that they were made in the disk of gas and solids that formed the Sun and planets 4.5 billion years ago. Fifty scientists from assorted disciplines have collaborated to review how chondrules could have formed in the protoplanetary disk. When and where in the disk did they form? What were they made from and how fast were they heated and cooled? What provided the energy to melt chondrules - nebular shock waves, lightning discharges, protostellar jets? Following an exciting international conference in Albuquerque, New Mexico, the latest answers to these questions are presented in thirty-four articles.

When this book was published in 2006, it had been just over ten years since the first planet outside our solar system was detected. Since then, much work has focused on understanding how extrasolar planets may form, and discovering the frequency of potentially habitable Earth-like planets. This volume addresses fundamental questions concerning the formation of planetary systems in general, and of our solar system in particular. Drawing from advances in observational, experimental and theoretical research, it summarises our understanding of the planet formation processes, and addresses major open questions and research issues. Chapters are written by leading experts in the field of planet formation and extrasolar planet studies. The book is based on a meeting held at Ringberg Castle in Bavaria, where experts gathered together to present and exchange their ideas and findings. It is a comprehensive resource for graduate students and researchers, and is written to be accessible to newcomers to the field.

One of the first maps of Mars, published by an Italian astronomer in 1877, with its pattern of canals, fueled belief in intelligent life-forms on the distant red planet - a hope that continued into the 1960s. Although the Martian canals have long since been dismissed as a famous error in the history of science, K. Maria D. Lane argues that there was nothing accidental about these early interpretations. Indeed, she argues, the construction of Mars as an incomprehensibly complex and engineered world both reflected and challenged dominant geopolitical themes during a time of major cultural, intellectual, political, and economic transition in the Western world. "Geographies of Mars" telescopes in on a critical period in the development of the geographical imagination, when European imperialism was at its zenith and American expansionism had begun in earnest. Astronomers working in the new observatories of the American Southwest or in the remote heights of the South American Andes were inspired, Lane finds, by their own physical surroundings, and they used representations of the Earth's arid landscapes to establish credibility for their observations of Mars. With this simple shift to the geographer's point of view, Lane deftly explains some of the most perplexing stances on Mars taken by familiar protagonists such as Percival Lowell, Alfred Russel Wallace, and Lester Frank Ward. A highly original exploration of geography's spatial dimensions at the beginning of the twentieth century, "Geographies of Mars" offers a new view of the mapping of far-off worlds.

The present well-established study of planets orbiting stars other than our Sun, the exoplanets, was reviewed by the author in his earlier book Wandering Stars. This new and exciting field of study has expanded quickly, particularly due to technological advances in both Earth-based telescopes and, more recently, in the application of automatic space vehicles. Well over 300 exoplanets have now been catalogued, each of mass comparable to or greater than those of the major planets of the Solar System. Earth-sized bodies remain out of reach for the present. The data obtained so far show that the distribution of major planets in our Solar System is the exception rather than the rule, contrary to earlier expectations. A few exoplanet systems do, nevertheless, give the promise of broadly Solar System conditions with the possibility of Earth-like components in appropriate orbits.This immediately raises the age-old question of whether there can be life elsewhere in the Universe and whether this might involve advanced technologically-capable beings like ourselves. The topic is explored in this workbook. To gain a balanced perspective on these matters, the arguments are set against the broad panorama of the Universe on the one hand and on the evolution of life on Earth leading to Homo sapiens on the other. More than this, the apparatus for achieving technological excellence, such as the development of appropriate energy sources and the invention of the required mathematical skills, is also included. This wide range of arguments is unusual.This notebook-cum-workbook provides a firm and comprehensive introduction to these studies. It is written by an expert in the field for readers beginning to ponder these questions seriously. It is hoped that the reader will extend the arguments further as the subject develops. A special feature is an extensive compendium to act as the beginnings of a personal inventory. The Inverted Bowl is in a very real sense a companion to Wandering Stars.

Memoir and Correspondence of Caroline Herschel (1876) contains the letters and diaries of the celebrated astronomer Caroline Herschel (1750-1848), edited by her niece, Mary Herschel. Caroline was born in Hanover to a musician father and an illiterate mother who did not want her daughter to be educated. However Caroline's brother William, an organist employed in Bath, persuaded their mother to allow Caroline to join him there. She left for England in 1772 to live with William, to whom she remained devoted all of her life. In Bath, William turned towards telescope-making and astronomy, to such effect that in 1781 he discovered the planet Uranus. He was appointed 'the King's astronomer' in 1782, and Caroline, trained by William, continued to work at his side as a scientist in her own right. Between them, they discovered eight comets and raised the number of recorded nebulae from a hundred to 2500.

Written in 1877 by the French journalist Amedee Guillemin, this work appeared on British bookshelves at a time of intense interest in space, the solar system and stars. In the same year, Schiaparelli made his infamous 'discovery' of Martian canals, whetting the public's appetite for all things astronomical. Guillemin's account of comets was equally ambitious and, ultimately, more valuable. His subjects range from comet superstitions in Renaissance Italy to an accessible explanation of their orbits, constitution and brilliance. As James Glaisher notes in his Preface, 'there is no work that at all occupies the ground covered' by Guillemin. The author's imaginative prose, exemplified by his description of comets as 'long disowned stars', was translated sympathetically by Glaisher. Accompanied by eighty-five striking illustrations, including Halley's Comet as depicted in the Bayeux Tapestry, The World of Comets provides a fascinating insight into both astronomy and nineteenth-century scientific enquiry.

Heliophysics is a fast-developing scientific discipline that integrates studies of the Sun's variability, the surrounding heliosphere, and the environment and climate of planets. Over the past few centuries, our understanding of how the Sun drives space weather and climate on the Earth and other planets has advanced at an ever increasing rate. This 2010 volume, the last in this series of three heliophysics texts, focuses on long-term variability from the Sun's decade-long sunspot cycle and considers the evolution of the planetary system over ten billion years from a climatological perspective. Topics covered range from the dynamo action of stars and planets to processes in the Earth's troposphere, ionosphere, and magnetosphere and their effects on planetary climate and habitability. Supplemented by online teaching materials, it can be used as a textbook for courses or as a foundational reference for researchers in fields from astrophysics and plasma physics to planetary and climate science.

An Irish astronomer and talented mathematician, Sir Robert Stawell Ball (1840-1913) was also a prolific writer of popular astronomy. As a young man, Ball conducted observations of nebulae using Lord Rosse's telescope - at the time the largest in the world. His Story of the Heavens displays the same fascination with the beauties and mysteries of the sky, providing a detailed survey of the history and contemporary situation of the solar system, and speculating about the possibility of life on other planets. Originally published in 1885, when Ball was Andrews Professor of Astronomy in the University of Dublin and Royal Astronomer of Ireland, this beautifully illustrated volume covers all eight planets, the Sun, as well as double stars, distant suns, comets, and the Milky Way. Extremely popular in its time, this book remains relevant today for its historical account of astronomy as a science.

When Edwin Dunkin (1821 1898) published this book in 1869, it was received with widespread acclaim by both professional astronomers and the reading public. Dunkin, a distinguished astronomer who published widely in academic journals and later served in the prestigious roles of Deputy Astronomer Royal (1881 1884) and President of the Royal Astronomical Society (1880), is still best known for this work of popular astronomy that has functioned as an indispensable tool for generations of amateurs. Chapter 1 derives from Dunkin's famous 'The Midnight Sky at London' articles, previously published in Leisure Hour, which describe the London midnight sky during each month of the year. Other chapters cover the Southern Hemisphere, the constellations, the properties of fixed stars, the solar system, and meteors and shooting stars. The volume is well illustrated with star maps and engravings. It is a classic work of popular nineteenth-century astronomical writing.

James Ferguson (1710-1776) was a Scottish self-taught astronomer, instrument maker and artist. Of humble background, he became a highly successful lecturer on experimental philosophy and science. He became a Fellow of the Royal Society in 1763, received a royal pension, and is particularly remembered as an inventor and improver of astronomical and other scientific apparatus. These include a new type of orrery, clocks, and his astronomical rotula. His lectures and books were noted for their clear explanations for a general audience, and Astronomy Explained upon Sir Isaac Newton's Principles and Made Easy for Those Who Have Not Studied Mathematics (1756) was a bestseller. This autobiographical memoir, expanded by Ebenezer Henderson in 1867, also contains a full description of Ferguson's principal inventions, with many illustrations.

Elias Loomis (1811 1889), Professor of Mathematics and Natural Philosophy at the University of the City of New York, published the third edition of this key work in 1856, at a time when the discipline of astronomy was making rapid advances. Recent technological progress had led to a phenomenal number of astronomical discoveries: the existence of a new planet, Neptune; a new satellite and ring for Saturn; irregularities in the movement of many planets and stars; thirty-six new asteroids; numerous comets; extensive catalogues of stars; and new and important observations on the sun. Loomis' report is a treasure-trove of information regarding these discoveries and the significance they had at the time. The chapters on the history of American observatories, various astronomical expeditions, public astronomical surveys, and telescope manufacturing in the USA provide access to information not otherwise available. Recent Progress is a key text in the history of astronomy.

Thomas William Webb (1807 1885) was an Oxford-educated English clergyman whose deep interest in astronomy and accompanying field observations eventually led to the publication of his Celestial Objects for Common Telescopes in 1859. An attempt 'to furnish the possessors of ordinary telescopes with plain directions for their use, and a list of objects for their advantageous employment', the book was popular with amateur stargazers for many decades to follow. Underlying Webb's celestial field guide and directions on telescope use was a deep conviction that the heavens pointed observers 'to the most impressive thoughts of the littleness of man, and of the unspeakable greatness and glory of the Creator'. A classic and well-loved work by a passionate practitioner, the monograph remains an important landmark in the history of astronomy, as well as a tool for use by amateurs and professionals alike.
