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.
Information collected by satellites recently sent by the USA, the European Space Agency, Japan, Germany, the United Kingdom, and Russia to monitor the Sun has changed our knowledge and understanding of the Sun, particularly its effect on Earth. This book presents these findings in a way that will be welcomed by amateur astronomers, students, educators and anyone interested in the Sun. Enhanced by many colour photographs, the book combines newly acquired scientific understanding with detailed descriptions of features visible on the Sun s surface and in its atmosphere. In the past, observing the Sun has been left to academics with specialised instruments, since solar observation has been unsafe because of the risk of eye damage. This book explains how amateur astronomers can safely observe the various solar phenomena using special hydrogen-alpha telescopes that are not too expensive. Amateurs can now make a positive contribution to science by monitoring the Sun as professionals do. Amateurs can also access the solar images taken by satellites via the internet. This book helps readers interpret and understand what these images are showing about the Sun, including the latest 3D images. Solar observers will enjoy comparing their own solar telescope observations with those produced by space probes such as SDO, SOHO, Hinode and STEREO, and further enjoy learning about transits, eclipses, and space weather and how the Sun compares to other stars in the universe. The main purpose of this book is to present some of the fascinating solar phenomena in their full splendor to readers through a variety of illustrations, photographs and easy to understand text.
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.
This handbook is a guide to exploring the classical night sky and its wonderful telescopic sights. All 88 officially recognized constellations are presented in natural groups which are related by their origin and location in the sky. Each group is explained by a fascinating story which tells what each constellation represents, how it appears in the sky, and why the other constellations of the group are close by, or related in some other manner. Some of these stories are classical myths which show how and why ancient cultures saw the constellations as related groups. Others are about more modern astronomers who sought recognition by filling in the gaps between the ancient constellations with inventions of their own. Both types of stories are crafted to make the constellation groups memorable, so that amateur astronomers can not only locate and recognize the constellations more easily, but also be able to pinpoint the celestial objects they contain more quickly. Specific instructions are given for finding each constellation, how to spell and pronounce the constellation and star names, plus the origins of the star names. Finder charts show each constellation group and a large area of sky around the group. These charts also indicate pointer stars which aid in finding the constellations. More detailed charts show how each constellation figure is visualized through simple line drawings. For each constellation, there is a table of about 10 to 30 telescopic objects selected to include a wide range of difficulty. Some can be glimpsed with the unaided eye, others require a 12 or 14 inch telescope. All the most prominent telescopic objects are included, plus a varied selection of interesting, but much more difficult objects. The tables include each object s celestial coordinates, type, size, brightness, other information specific to each type of object, and a recommendation of the appropriate telescope size needed for good viewing. There are also photographs of constellations and telescopic objects, detailed locator charts for the hard-to-find objects, and plots of binary star orbital motions. The same charts used to show the constellation figures are repeated, with the addition of symbols indicating the locations of all the selected telescopic objects. An index and seven appendices help the user find specific objects or classes of objects.
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.
Exoplanets: Finding, Exploring, and Understanding Alien Worlds probes the basis for possible answers to the fundamentals questions asked about these planets orbiting stars other than our Sun. This book examines what such planets might be like, where they are, and how we find them. Until around ten years ago, the only planets that we knew about were within the Solar System. The first genuine planet beyond the confines of the Solar System was discovered only 1988. Since then another 350 or so exoplanets have been detected by various methods, and most of these haven been found in the last ten years. Although many more exoplanets discoveries may be expected to occur even as this book is being read, a large enough data set is now available to form the basis for an informed general account of exoplanets. The topic hence is an extremely "hot" one - all the more so because the recently launched Kepler spacecraft should soon start uncovering many more exoplanets, some perhaps comparable with the Earth (and therefore possibly alternative homes for mankind, if we could ever reach them). Exoplanets: Finding, Exploring, and Understanding Alien Life gives a comprehensive, balances, and above all accurate account of exoplanets.
Grappling with Gravity explores the physiological changes that will occur in humans and the plants and animals that accompany humans as we move to new worlds, be it to colony in the emptiness of space or settlements on the Moon, Mars, or other moons or planets. This book focuses on the biomedical aspects, while not ignoring other life-changing influences of space living. For example, what happens to people physiologically in the microgravity of space, where weight and the direction "up" become meaningless? Adapting to microgravity represents the greatest environmental challenge that life will have encountered since our ancestors moved from the seas to solid Earth. Away from Earth the human body will begin almost immediately to adapt and change, to be able to function in these strange environments. As a person adapts in space he or she will become less fit to live on Earth.
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.
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.
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.

Six Months in Ascension, first published in 1878, contains an account by Isobel Sarah B. Gill of the 1877 scientific expedition to the island of Ascension, in the South Atlantic, undertaken to measure the distance of the sun from the earth by observing the opposition of the planet Mars. The expedition, funded by the Royal Astronomical Society, was led by Isobel's husband, the astronomer David Gill, with a heliometer and other scientific instruments provided by Lord Lindsay. Isobel accompanied the expedition as her husband's companion. Her account offers personal details and stories omitted from the scientific reports on the expedition written by her husband and colleagues and it contains beautiful descriptions of the island of Ascension. The book offers a rare view of the personal, practical and behind-the-scenes side of a nineteenth-century scientific expedition and provides a fascinating insight into the gender roles of learned Victorian society.
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.
The Moon is not just a static piece of cosmic matter in our night sky, but a dynamic living being. Throughout her journey around the Earth which takes about 29.5 days she shows us her different faces, growing from a silver sliver in the sky to an awe-inspiring illuminated sphere, before returning to darkness again. She changes colour and moves through a variety of star constellations reflecting the energies at play each day. The Moon gives us a map to a cyclical way of living; the blueprint for a life that breathes in harmony with the rhythm of the natural world around us. She teaches us about the importance of embracing quiet and reflective times as much as celebrating the times we experience life in its fullest expression. She informs us when to plant the seeds of our dreams and when to take stock and harvest what we have been growing. What will you discover about yourself when you tune into the moon?
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.
Information collected by recent space probes sent to explore the Moon by the USA, the European Space Agency, Japan, China and India has changed our knowledge and understanding of the Moon, particularly its geology, since the Apollo missions. This book presents those findings in a way that will be welcomed by amateur astronomers, students, educators and anyone interested in the Moon. Enhanced by many colour photos, it combines newly acquired scientific understanding with detailed descriptions and labelled photographic maps of the lunar surface. Guided by observation methods explained in the book and 17 Study Areas presented and carefully explained in the last chapter, amateur astronomers can observe these features from Earth using telescopes and binoculars. Readers who consult the photographic maps will gain a better understanding about the Moon's topography and geology. The book is rounded out by a helpful glossary.
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.
This book provides an updated overview of the processes determining the influence of solar forcing on climate. It discusses in particular the most recent developments regarding the role of aerosols in the climate system and the new insights that could be gained from the investigation of terrestrial climate analogues. The book s structure mirrors that of the ISSI workshop held in Bern in June 2005.
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.
Jeremiah Horrox (1618-1641) was one of the most interesting astronomers Britain has ever produced, and his tragically early death deprived the field of one of its most brilliant talents. In his short life he achieved much, having mastered the current state of astronomy at Cambridge University and going on to make important new calculations about the diameter and position of known planets, moons and stars. In the 1660s and 70s several prominent scientists, including Huygens, Newton and Flamsteed, took an interest in Horrox's discoveries and published his surviving treatises. This memoir of 1859 was part of a Victorian revival of interest in Horrox. It includes translation of his major work, Venus in Sole Visa, a draft of a treatise on the transit of Venus, in which he describes the conjunction of Venus with the sun, which he correctly calculated and observed in 1639.
The Reuven Ramaty High Energy Solar Spectroscopic Imager
(RHESSI) satellite was launched on 5 February 2002. Its objective
is to study the energy release and particle acceleration in solar
flares through observations of X-rays and gamma rays. Two novel
technologies are combined to obtain both spectra and images over a
broad energy range. For the spectroscopy, cooled hyperpure
germanium detectors are used to cover the energy range from 3 keV
to 17 MeV with unprecedented keV-class resolution. Since focusing
optics are not possible for making images with such high energy
photons, tungsten and molybdenum absorbing grids are used to
modulate the X-rays and gamma-rays coming from the Sun as the
spacecraft rotates. This allows the spatial Fourier components of
the source to be determined so that images can be made in spectral
ranges where astronomical images have never been produced before.
These new instrumental techniques require equally innovative
software to reconstruct X-ray and gamma-ray spectra and images from
the observations.
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.
The Herschels in this biography are Sir William Herschel (1738 1822), his sister Caroline (1750 1848) and Sir John Herschel (1792 1871), William's son. Sir William was an astronomer and telescope-maker who discovered the planet Uranus in 1781. He was appointed 'the King's astronomer' to George III in 1782, and under his patronage built the then largest telescope in the world. Caroline Herschel worked as her brother's assistant for much of his career but was also an accomplished astronomer in her own right, discovering eight comets and producing a catalogue of nebulae. Her nephew Sir John Herschel was also a distinguished astronomer who made many observations of stars in the southern hemisphere. This book by the astronomer and writer Agnes Clerke (1842 1907), published in 1895, provides both an analysis of their work and an assessment of its contribution to later astronomical research.
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. |
