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."

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.

Provides novice to accomplished amateur astronomers with a firm grounding in the basics and successful use of digital astrophotography.

Provides examples of the best images, and gives readers hints and tips about how to get the best out of this extraordinary technology.

Experts in CCD astronomy from North America and Europe have contributed to this book, illustrating their help and advice with many beautiful colour images the book is in full color throughout.

Techniques range from using simple webcams to highly technical aspects such as supernovae patrolling.

Computer processing, stacking and image-enhancement are detailed, along with many hints and tips from the experts.

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.

Every night, astronomers use a new generation of giant telescopes at observatories around the world to study phenomena at the forefront of science. By focusing on the history of the Gemini Observatory--twin 8-meter telescopes located on mountain peaks in Hawaii and Chile--"Giant Telescopes" tells the story behind the planning and construction of modern scientific tools, offering a detailed view of the technological and political transformation of astronomy in the postwar era.

Drawing on interviews with participants and archival documents, W. Patrick McCray describes the ambitions and machinations of prominent astronomers, engineers, funding patrons, and politicians in their effort to construct a modern facility for cutting-edge science--and to establish a model for international cooperation in the coming era of "megascience." His account details the technological, institutional, cultural, and financial challenges that scientists faced while planning and building a new generation of giant telescopes. Besides exploring how and why scientists embraced the promise and potential of new technologies, he considers how these new tools affected what it means to be an astronomer. McCray's book should interest anyone who desires a deeper understanding of the science, technology, and politics behind finding our place in the universe.

"A Treatise the Astrolabe" by Geoffrey Chaucer is the work of an avid amateur astronomer who happened also to be England's greatest medieval poet. A user of the astrolabe can plot the movement of the stars, tell time, and calculate numerous other results. Chaucer translated and revised a standard Latin treatment of the astrolabe. His treatise, which is generally regarded as one of the first technical manuals in English and a model of how technical manuals should be written.

Not since 1872 has a free-standing edition of "A Treatise the Astrolabe" been published. Thanks to the expertise of its editor, Sigmund Eisner, who supplies sixty-eight illustrations, this Variorum edition provides a more detailed exposition than previously available. Eisner's extensive labors result in the first complete record of textual variants found in the thirty-two surviving manuscripts of the work and in all the major printed text published between 1532 and 1987. This landmark edition also presents a thorough digest of all published commentary on Chaucer's treatise.

Amplified by sixty-eight illustrations, this variorum edition of Chaucer's "A Treatise on the Astrolabe" provides a more detailed exposition of the treatise than has ever before been available.

Celestial Delights is essentially a 'TV Guide' for teh sky. This will be its third edition. This title, which has aggregated sales of about 20,000 copies to date in its two previous editions and has found a niche with skygazers, is much awaited. Through extensive graphics integrated with an eight-year-long calendar of sky events, it provides a look at "don't miss" sky events, mostly for naked-eye and binocular observing. The book is organized by ease of observation - lunar phases and the brighter planets come first, while solar eclipses, the aurora, and comets come later. Celestial Delights also includes a hefty dose of sky lore, astronomical history, and clear overviews of current science. It provides a handy reference to upcoming naked-eye events, with information broken out in clear and simple diagrams and tables that are cross-referenced against a detailed almanac for each year covered. Most broad-ranging astronomy field guides focus on stars, constellations, and the deep sky, but tend to ignore planetary events, which are in by far the most widely observable aspects of the changing night sky. Celestial Delights puts a variety of information all in one place, presents it in a friendly way that does not require prior in-depth astronomical knowledge, but provides the context and historical background for understanding events that astronomical computer programs or web sites lack.

Together, this two-volume set provides amateur astronomers with all the information they require to set up their telescopes and embark upon an exciting exploration of the night sky. Complete with trouble-shooting advice, practical tips for observing over 200 interesting celestial objects, and information about the latest products and resources, this set of Covington's two books is an essential purchase for every new telescope owner.

Electromagnetic Scintillation describes the phase and amplitude fluctuations imposed on signals that travel through the atmosphere. The two volumes of Electromagnetic Scintillation will constitute a modern reference and comprehensive tutorial, treating both optical and microwave propagation and integrating measurements and predictions at each step of the development. This first volume deals with phase and angle-of-arrival measurement errors, accurately described by geometrical optics and will be followed by a second volume on weak scattering. In this book, measured properties of tropospheric and ionsopheric irregularities are reviewed first. Electromagnetic fluctuations induced by these irregularities are then estimated for a wide range of applications.

The emphasis of Planetary Atmospheres is on comparative aspects of planetary atmospheres, generally meaning comparison with the Earth, including atmospheric composition, thermal structure, cloud properties, dynamics, weather and climate, and aeronomy. The goal is to look for common processes at work under different boundary conditions in order to reach a fundamental understanding of the physics of atmospheres. As part of a general Physics course, the material is chosen to emphasise certain aspects that will be of broad topical interest:
- evolutionary processes, setting the Earth in its context as a planet and a member of the Solar System
- the properties of atmospheres that affect the climate near the surface of each planet
- measurement techniques and models, where the same experimental and theoretical physics is applied under different conditions to investigate and explain atmospheric behaviour.
These might be thought of as the astronomical, environmental, and technical sides of the discipline respectively.
The book covers the basic physics of planetary atmospheres in a single text for students or anyone interested in this area of science. The approach is the same as in the author's previous book Elementary Climate Physics: an overview, followed by more detailed discussion of key topics arranged by physical phenomenon and not planet by planet as usually found in this field. There is an emphasis on acquiring and interpreting measurements, and the basic physics of instruments and models, with key definitions and some historical background in footnotes and in the glossary at the end of the book.

Variable stars have long been favourite targets for amateur astronomers. Nothing demonstrates the dynamic nature of our universe more than variable stars. They vary in brightness, either in a periodic fashion or in an irregular pattern. These can be as simple as eclipsing naked eye stars like beta Lyrae, or pulsating giants like Mira (which provide a yardstick for measuring the distance of other galaxies) or as extraordinary as variable stars that are destroying themselves, like SN1987A.

The rate, period and form of variability tells us a great deal about the star itself a" its physical form, and the processes that drive the variability. Not only are variable stars interesting to observe and analyze, they are also the cornerstone of much of astronomy, yielding secrets of stellar interiors, distances to galaxies, and even demonstrating the basic expansion of the universe.

Variable Stars, and How to Observe Them begins by looking at the physics a" the different types or variable star (and the reasons for the variability) a" and considers the different forms in detail. The second part of the book describes how amateur astronomers can make useful observations with a range of commercially-available instruments, from binoculars, through Dobsonians to larger instruments equipped with advanced CCD cameras.

Explains how to select equipment that is at the 'next level', and describes how to use more advanced telescopes and accessories. This book includes a section on imaging and equipment that range from regular digital cameras, through web cams, to specialized chilled-chip CCD cameras.

This title details the essential roles that small telescopes should play in 21st century science and how their future productivity can be maximized. Over 70 experts from all corners of the international astronomical community have created a reference on the future of "big science with small telescopes". Despite highly publicized closures of telescopes smaller than 4-m in aperture at national facilities and their omission from national science priority studies, the oft-lamented demise of the small telescope has been greatly exaggerated. In fact, the future of these workhorses of astronomy will be brighter than ever if creative steps are taken now. This three-volume set defines essential roles that small telescopes should play in 21st century science and the ways in which a productive future for them can be realized. A wide cross-section of the astronomical community has contributed to a definitive assessment of the present and a vision for the future. Beginning with a summary of national scientific priority-setting efforts, volume one of this three-volume set examines the public's and the astronomical communities' own perceptions and misconceptions of small telescope productivity. These shape the future scientific research that will be done with telescopes smaller than 4-m in aperture and the number of astronomers that will have access to them.

On October 1, 1958, the world's first civilian space agency opened for business as an emergency response to the Soviet Union's launch of Sputnik a year earlier. Within a decade, the National Aeronautics and Space Administration, universally known as NASA, had evolved from modest research teams experimenting with small converted rockets into one of the greatest technological and managerial enterprises ever known, capable of sending people to the Moon aboard gigantic rockets and of dispatching robot explorers to Venus, Mars, and worlds far beyond. In spite of occasional, tragic setbacks in NASA's history, the Apollo lunar landing project remains a byword for American ingenuity; the winged space shuttles spearheaded the International Space Station and a dazzling array of astronomical satellites and robotic landers, and Earth observation programs have transformed our understanding of the cosmos and our home world's fragile place within it. Throughout NASA's 60-year history, images have played a central role. Who today is not familiar with the Hubble Space Telescope's mesmerizing views of the universe or the pin-sharp panoramas of Mars from NASA's surface rovers? And who could forget the photographs of the first men walking on the Moon? Researched with the collaboration of NASA, this collection gathers more than 400 historic photographs and rare concept renderings, scanned and remastered using the latest technology and reproduced in extra-large size. Texts by science and technology journalist Piers Bizony, former NASA chief historian Roger Launius, and best-selling Apollo historian Andrew Chaikin-and an extensive mission checklist documenting the key human and robotic missions-round out this comprehensive exploration of NASA, from its earliest days to its current development of new space systems for the future.The NASA Archives is more than just a fascinating pictorial history of the U.S. space program. It is also a profound meditation on why we choose to explore space and how we will carry on this grandest of all adventures in the years to come.

Why write a book about the stars? Of what use is their study? This book covers this ground with a number of anecdotes arising from the author's almost 60 years' experience as a research scientist who has worked with some of the largest telescopes in the world. The text exposes much of what is glossed over in the canned information that the public get and holds nothing back with respect to uncertainties within the subject. People want answers, want somehow to be reassured that someone out there has a handle on things. This book details the basis for our knowledge of the universe, warts and all, and offers important insights as to where the science is going.
