Every year large numbers of people take up the study of astronomy, mostly at amateur level. There are plenty of elementary books on the market, full of colourful photographs, but lacking in proper explanations of how and why things are as they are. Many people eventually wish to go beyond the 'coffee-table book' stage and study this fascinating subject in greater depth. This book is written for them. In addition, many people sit for public examinations in this subject each year and this book is also intended to be of use to them. All the topics from the GCSE syllabus are covered here, with sample questions at the end of each chapter. Astronomy Explained provides a comprehensive treatment of the subject in more depth than is usually found in elementary works, and will be of interest to both amateur astronomers and students of astronomy.

Market: Students and researchers in geophysics, astronomy, and astrophysics. This book reports on the timely Earth Observing System (EOS) Program's wide range of scientific investigations, observational capabilities, vast data and information system, and educational activities. Because its primary goal is to determine the extent, causes, and regional consequences of global climate change, this program provides the scientific knowledge needed by world leaders to formulate sound and equitable environmental policies.

The recent launch of NASA's Gamma-Ray Observatory will increase interest in gamma-ray astronomy. This is a fully up-dated new edition of the authors' earlier volume published in 1986 and covers both the background science and the current state-of-the-art in this field. The emphasis is on the astronomy and astrophysics of known sources of cosmic gamma-rays outside the solar system. The authors discuss the mechanisms for the production and absorption of gamma-rays. The gamma-ray line astronomy of the interstellar medium, galactic centre, and various discrete sources is then considered. Gamma-ray bursts are treated in considerable detail in chapter three, and the final two chapters describe medium energy and ultra-high energy gamma-rays. Relevant data from supernova SN1987A is also included in this edition. The book includes comprehensive references to the primary literature, together with many figures and tables. The concentration on phenomenology makes this book a fine introduction to gamma-ray astronomy.

In this volume the creator and director of Jodrell Bank, the world's largest radio telescope, tells the fascinating story behind the building of this huge telescope. Though the telescope is popularly known for tracking and communicating with man-made satellites, its prime function is the study of the universe by means of radio waves emitted by distatant stars. The radiation received from meteors, the moon, the Andromeda Galaxy, and the Milky Way offers new information daily about the origins of life on this planet and the possibilities of life on other worlds. The building of the telescope was fraught with mishaps and frustrations-financial, political, and otherwise; yet, through his perseverance, Sir Bernard Lovell made its creation a reality. His story, drawn largely from personal diaries, documents the complex conflicts among scientists, bureaucrats, and politicians which arose out of this monumental endeavor.

How to Use a Computerized Telescope describes how to get a computerized telescope up-and-running, and how to embark on a program of observation. Michael Covington explains in detail how the sky moves, how a telescope tracks it, and how to get the most out of any computerized telescope. Packed full of practical advice and tips for troubleshooting, his book gives detailed instructions for three popular telescopes: the Meade® LX200, Celestron^DCC NexStar 5 and 8, and Meade® Autostar^DTM (ETX and LX90). Michael A. Covington is an associate research scientist at the University of Georgia. He is a computational linguist trained in the computer processing of human language and the computer modeling of human logical reasoning, and a widely recognized expert on the Prolog programming language. He is the author of nine books including Dictionary of Computer and Internet Terms, Seventh Edition (Barron's, 2000), Astrophotography for the Amateur (Cambridge, 1999), PROLOG Programming in Depth (Simon & Schuster, 1996), Cambridge Eclipse Photography Guide (1993), and Syntactic Theory in the High Middle Ages (Cambridge, 1985). A senior member of the Institute of Electrical and Electronics Engineers, Covington is a Contributing Editor to, and former "Q&A" columnist of, Poptronics magazine.

The leading Australian astronomer of his generation, John Bolton (1922-93), was born in Sheffield and educated at Cambridge University. After wartime service in the Royal Navy, he arrived in Sydney and joined the CSIRO Radiophysics Laboratory. In the late 1940s he discovered and identified the first discrete radio sources, unusual objects at vast distances with intense emission at radio frequencies. These discoveries marked the birth of a new field - extragalactic radio astronomy. Bolton had the unusual distinction of being the inaugural director of two new observatories. In the late 1950s he built the first major observatory for radio astronomy at Caltech in the United States, returning to Australia to take charge of the newly completed Parkes telescope - featured in the acclaimed film The Dish - in New South Wales. In this thoroughly researched and generously illustrated biography, Peter Robertson tells the remarkable story of how John Bolton, and his CSIRO colleagues, propelled Australia to the forefront of international radio astronomy.

Having escaped domestic servitude in Germany by teaching herself to sing, and established a career in England, Caroline Herschel learned astronomy while helping her brother William, then Astronomer Royal. Soon making scientific discoveries in her own right, she swept to international scientific and popular fame. She was awarded a salary by George III in 1787 - the first woman in Britain to make her living from science. But, as a woman in a male-dominated world, Herschel's great success was achieved despite constant frustration of her ambitions. Drawing on original sources - including Herschel's diaries and her fiery letters - Claire Brock tells the story of a woman determined to win independence and satisfy her astronomical ambition.

Mt John University Observatory is New Zealand's only professional research observatory for optical astronomy. In 1965, Mt John University Observatory was founded at Lake Tekapo in the Mackenzie Basin to take advantage of the favorable conditions for astronomy. Telescopes were installed, and in 1981 a lighting ordinance helped protect the site from light pollution. Astronomical research had been thriving on Mt John for 40 years when astrotourism started to take off. Today Mt John is both a research observatory and a mecca for stargazing astrotourists, who come to see the pristine landscape and the amazing dark night skies. It is one of the most beautiful astronomical observatories in the world, but also a place with an often turbulent history, having been rocked by personality battles, funding shortfalls, student demonstrations, and, on one occasion, a destructive fire. In spite of all that, its scientific work has been an outstanding success, and Mt John's research work, especially in stellar astronomy, is known and respected around the world. This richly illustrated account follows the development of an iconic New Zealand scientific institution.

A rare look at the southern skies' greatest glories.

The celestial objects of the Southern Hemisphere are fascinating to astronomers everywhere. The southern stars, nebulae, and galaxies have exotic names like Omega Centauri, the Tarantula Nebula, Canopus, the Vela Supernova, the Coal Sack, and the Magellanic Clouds.

And there's more: the Southern Milky Way is crammed with clusters and nebulae of great interest to resident astronomers of the southern hemisphere, and to the many visitors from the north who relish the opportunities to view the clear, dark skies of the interiors of southern Africa and Australia with binoculars, telescopes and cameras.

"Pearls of the Southern Skies" depicts 71 Deep Sky Objects photographed by Dieter Willasch and described in detail by Auke Slotegraaf. The text and pictures are laid out season by season, and accompanied by 15 easy-to-use full-color location charts.

In less than a century, the accepted picture of the universe transformed from a stagnant place, composed entirely of our own Milky Way galaxy, to a realm inhabited by billions of individual galaxies, hurtling away from one another. We must thank, in part, Edwin P. Hubble, one of the greatest observational astronomers of the 20th century. In 1936, Hubble described his principal observations and conclusions in "The Realm of the Nebulae," which quickly became a classic work. Two new introductory pieces, by Robert P. Kirshner and Sean M. Carroll, explain advances since Hubble's time and his work's foundational importance.
"Meaningful, historically accurate, and thoroughly delightful reading."--Gail O. Clark, "Astronomy"

La Caille was one of the observational astronomers and geodesists who followed Newton in developing ideas about celestial mechanics and the shape of the earth. He provided data to the great 18th-century mathematicians involved in understanding the complex gravitational effects that the heavenly bodies have on one another. Observing from the Cape of Good Hope, he made the first ever telescopic sky survey and gave many of the southern constellations their present-day names. He measured the paths of the planets and determined their distances by trigonometry. In addition, he made a controversial measurement of the radius of the earth that seemed to prove it was pear-shaped. On a practical level, La Caille developed the method of 'Lunars' for determining longitudes at sea. He mapped the Cape. As an influential teacher he propagated Newton's theory of universal gravitation at a time when it was only beginning to be accepted on the European continent. This book gives the most comprehensive overview so far available of La Caille's life and work, showing how he interacted with his often difficult colleagues. It places special emphasis on his life at, and his observations and comments on, the Cape of Good Hope, where he spent the years 1751-53.

In the 42 years that Edward Pickering directed the Harvard College Observatory, he and his team of women "computers" made strides in promoting the new field of astrophotography, discovered the first spectroscopic binary star system, and cataloged more than 225,000 stars. Pickering hired women such as Henrietta Leavitt, who found a way to measure the distances to faraway stars, and Cecilia Payne-Gaposchkin, whose later work became the foundation for astrophysics, to process astronomical data gathered at the observatory. The advances these women made under Pickering's direction broadened the window of professional opportunity for women as well as our greater understanding of the universe. This new title highlights the lives of Pickering and his women "computers."

A multitude of measurement units exist within astronomy, some of which are unique to the subject, causing discrepancies that are particularly apparent when astronomers collaborate with researchers from other disciplines in science and engineering. The International System of Units (SI) is based on seven fundamental units from which other units may be derived, but many astronomers are reluctant to drop their old and familiar systems. This handbook demonstrates the ease with which transformations from old units to SI units may be made. Using worked examples, the author argues that astronomers would benefit greatly if the reporting of astronomical research and the sharing of data were standardized to SI units. Each chapter reviews a different SI base unit, clarifying the connection between these units and those currently favoured by astronomers. This is an essential reference for all researchers in astronomy and astrophysics, and will also appeal to advanced students.

Radio telescopes as well as communication antennas operate under the influence of gravity, temperature and wind. Among those, temperature influences may degrade the performance of a radio telescope through transient changes of the focus, pointing, path length and sensitivity, often in an unpredictable way. Thermal Design and Thermal Behaviour of Radio Telescopes and their Enclosures reviews the design and construction principles of radio telescopes in view of thermal aspects and heat transfer with the variable thermal environment; it explains supporting thermal model calculations and the application and efficiency of thermal protection and temperature control; it presents many measurements illustrating the thermal behaviour of telescopes in the environment of their observatory sites.

The book benefits scientists and radio/communication engineers, telescope designers and construction firms as well as telescope operators, observatory staff, but also the observing astronomer who is directly confronted with the thermal behaviour of a telescope.

The dark matter problem is one of the most fundamental and profoundly difficult problems in the history of science. Not knowing what makes up most of the mass in the Universe goes to the heart of our understanding of the Universe and our place in it. In Search of Dark Matter is the story of the emergence of the dark matter problem, from the initial 'discovery' of dark matter by Jan Oort to contemporary explanations for the nature of dark matter and its role in the origin and evolution of the Universe.

Written for the intelligent non-scientist and scientist alike, it spans a variety of scientific disciplines, from observational astronomy to particle physics. Concepts that the reader will encounter along the way are at the cutting edge of scientific research. However the themes are explained in such a way that no prior understanding of science beyond a high school education is necessary.
