The Galactic Centre represents a unique and extreme environment in the Galaxy. It hosts the Milky Way's supermassive black hole, its most concentrated dense gas reservoir and its most extreme star-formation environment. The Galactic Centre is therefore our nearest analogue to both an active galactic nucleus (AGN) and a starburst system. IAU Symposium 322 explores the revolution in our understanding of the Galactic Centre, driven by novel instrumentation including NuSTAR, ALMA, EHT and, in the near future, the Cherenkov Telescope Array (CTA). A number of anomalous, non-thermal signals have recently been discovered emanating from the Inner Galaxy. This volume addresses the question: are these signatures of dark matter or other new physics, or symptoms of the region's unusual astrophysics? Graduate students and researchers at the interface between astrophysics and particle physics have much to learn from studying this unique region.

In September of 1859, the entire Earth was engulfed in a gigantic cloud of seething gas, and a blood-red aurora erupted across the planet from the poles to the tropics. Around the world, telegraph systems crashed, machines burst into flames, and electric shocks rendered operators unconscious. Compasses and other sensitive instruments reeled as if struck by a massive magnetic fist. For the first time, people began to suspect that the Earth was not isolated from the rest of the universe. However, nobody knew what could have released such strange forces upon the Earth--nobody, that is, except the amateur English astronomer Richard Carrington.

In this riveting account, Stuart Clark tells for the first time the full story behind Carrington's observations of a mysterious explosion on the surface of the Sun and how his brilliant insight--that the Sun's magnetism directly influences the Earth--helped to usher in the modern era of astronomy. Clark vividly brings to life the scientists who roundly rejected the significance of Carrington's discovery of solar flares, as well as those who took up his struggle to prove the notion that the Earth could be touched by influences from space. Clark also reveals new details about the sordid scandal that destroyed Carrington's reputation and led him from the highest echelons of science to the very lowest reaches of love, villainy, and revenge.

"The Sun Kings" transports us back to Victorian England, into the very heart of the great nineteenth-century scientific controversy about the Sun's hidden influence over our planet.

IAU Symposium 285, New Horizons in Time-Domain Astronomy, gave a comprehensive overview of the status quo in 2011, exploring, astronomical variability at both Galactic and extragalactic distances. Several years later, IAU Symposium 339 witnessed a new level of activity and planning, with ambitious instruments that add a new dimension to some of those current in 2011 and ingenious methodology in the emerging field of astroinformatics. Major new instruments, whose output dwarfs those previously available, and analysis techniques that could not have been implemented until very recently, are being coupled with a broadening diversity in wavelengths. IAU S339 introduces the rich potential for new techniques for both analysis and communication, while covering the basic fundamentals such as data quality, standardization and archive access. Many early-career scientists are already central players in these projects: time-domain astronomy is the future and in their hands may it flourish and grow.

In the field of astrophysics, modern developments of practice are emerging in order to further understand the spectral information derived from cosmic sources. Radio telescopes are a current mode of practice used to observe these occurrences. Despite the various accommodations that this technology offers, physicists around the globe need a better understanding of the underlying physics and operational components of radio telescopes as well as an explanation of the cosmic objects that are being detected. Analyzing the Physics of Radio Telescopes and Radio Astronomy is an essential reference source that discusses the principles of the astronomical instruments involved in the construction of radio telescopes and the analysis of cosmic sources and celestial objects detected by this machinery. Featuring research on topics such as electromagnetic theory, antenna design, and geometrical optics, this book is ideally designed for astrophysicists, engineers, researchers, astronomers, students, and educators seeking coverage on the operational methods of radio telescopes and understanding the physical processes of radio astronomy.

The Dutch telescope and the Italian scientist Galileo have long enjoyed a durable connection in the popular mind--so much so that it seems this simple glass instrument transformed a rather modest middle-aged scholar into the bold icon of the Copernican Revolution. And yet the extraordinary speed with which the telescope changed the course of Galileo's life and early modern astronomy obscures the astronomer's own curiously delayed encounter with the instrument. This book considers the lapse between the telescope's creation in The Hague in 1608 and Galileo's alleged acquaintance with such news ten months later. In an inquiry into scientific and cultural history, Eileen Reeves explores two fundamental questions of intellectual accountability: what did Galileo know of the invention of the telescope, and when did he know it?

The record suggests that Galileo, like several of his peers, initially misunderstood the basic design of the telescope. In seeking to explain the gap between the telescope's emergence and the alleged date of the astronomer's acquaintance with it, Reeves explores how and why information about the telescope was transmitted, suppressed, or misconstrued in the process. Her revised version of events, rejecting the usual explanations of silence and idleness, is a revealing account of the role that misprision, error, and preconception play in the advancement of science.

Along the way, Reeves offers a revised chronology of Galileo's life in a critical period and, more generally, shows how documents typically outside the scope of early modern natural philosophy--medieval romances, travel literature, and idle speculations--relate to two crucial events in the history ofscience.

When Sultan bin Salman left Earth on the shuttle Discovery in 1985, he became the first Arab, first Muslim and first member of a royal family in space. Twenty-five years later, the discovery of a planet 500 light years away by the Qatar Exoplanet Survey - subsequently named `Qatar-1b' - was evidence of the cutting-edge space science projects taking place across the Middle East. This book identifies the individuals, institutions and national ideologies that enabled Arab astronomers and researchers to gain support for space exploration when Middle East governments lacked interest. Jorg Matthias Determann shows that the conquest of space became associated with national prestige, security, economic growth and the idea of an `Arab renaissance' more generally. Equally important to this success were international collaborations: to benefit from American and Soviet expertise and technology, Arab scientists and officials had to commit to global governance of space and the common interests of humanity. Challenging the view that the golden age of Arabic science and cosmopolitanism was situated in the medieval period, Determann tells the story of the new discoveries and scientific collaborations taking place from the 19th century to the present day. An innovative contribution to Middle East studies and history of science, the book also appeals to increased business, media and political interest in the Arab space industry.

Several Epoch of Reionization (EoR) experiments, for example, LOFAR, MWA and PAPER, are currently under way and producing results. These very deep observations not only set constraints on when and where the first sources formed in the early Universe and began (re)ionizing the predominantly neutral all-pervasive intergalactic medium, but they also provide high-quality data for cutting edge auxiliary foreground science. Obviously studying the physical origin of the foreground emission, whether Galactic or extragalactic, is a very exciting field in its own right and is of fundamental importance for perfecting the foreground removal techniques in the cosmological experiments. These proceedings of IAU S333 address both topics through giving the clearest and widest possible view on the EoR; presenting the state-of-the-art foreground science; and discussing challenges of upcoming and planned radio facilities such as HERA and SKA.

This is a George Adams' classic text, written in 1766, reprinted. George Adams (c. 1720-1773), optician and scientific writer, is best remembered as a maker of fine mathematical instruments and globes. He founded his eponymous company George Adams of London and was appointed Instrument Maker to the King. Late 18thC England witnessed the rise of an increasing public awareness of science, spreading beyond learned societies which found new devotees in royal courts, coffee houses, salons, lecture theatres, and in the homes of the gentry. "Science", no longer confined to the Royal Society of London, was transmitted by a growing body of lecturers and by the publication of ever more books, instruction manuals, and pamphlets on scientific subjects of which Adams' "Essay on the Use of Celestial & Terrestrial Globes" was a major publication of its time running to five editions between 1766 and 1808. This facsimile edition was first published by Pelican in 2006.

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.

"The Heavens on Earth" explores the place of the observatory in nineteenth-century science and culture. Astronomy was a core pursuit for observatories, but usually not the only one. It belonged to a larger group of "observatory sciences" that also included geodesy, meteorology, geomagnetism, and even parts of physics and statistics. These pursuits coexisted in the nineteenth-century observatory; this collection surveys them as a coherent whole. Broadening the focus beyond the solitary astronomer at his telescope, it illuminates the observatory's importance to technological, military, political, and colonial undertakings, as well as in advancing and popularizing the mathematical, physical, and cosmological sciences.
The contributors examine "observatory techniques" developed and used not only in connection with observatories but also by instrument makers in their workshops, navy officers on ships, civil engineers in the field, and many others. These techniques included the calibration and coordination of precision instruments for making observations and taking measurements; methods of data acquisition and tabulation; and the production of maps, drawings, and photographs, as well as numerical, textual, and visual representations of the heavens and the earth. They also encompassed the social management of personnel within observatories, the coordination of international scientific collaborations, and interactions with dignitaries and the public. The state observatory occupied a particularly privileged place in the life of the city. With their imposing architecture and ancient traditions, state observatories served representative purposes for their patrons, whether as symbols of a monarch's enlightened power, a nation's industrial and scientific excellence, or republican progressive values. Focusing on observatory techniques in settings from Berlin, London, Paris, and Rome to Australia, Russia, Thailand, and the United States, "The Heavens on Earth" is a major contribution to the history of science.

The Alfonsine Tables became the main computing tool for astronomers for about 250 years, from their compilation in Toledo ca. 1272 to the edition in 1551 of new tables based on Copernicus s astronomical models. It consisted of a set of astronomical tables which, over time, was presented in many different formats. Giovanni Bianchini (d. after 1469), an astronomer active in Ferrara, Italy, was among the few scholars of that extended period to compile a coherent and insightful set based on the Alfonsine Tables. His tables, described and analyzed here for the first time, played a remarkable role in the transmission of the Alfonsine Tables and in their transition from manuscript to print.

However deficient by modern standards was the astronomical knowledge of most early astronomers, one never ceases to wonder at the completeness and precision of some of their results, derived as they were from inaccurate observations made with the naked eye or with crude instruments. The main results of astronomy that could be discovered by the naked eye actually were discovered by the best ancient observers. "Planetary Systems from the Ancient Greeks to Kepler" describes the detailed technical models whereby astronomers prior to Newton accounted for their observations. Unlike histories of science that focus on the influence of great ideas, this book presents the actual substance of those ideas and details their elaboration and development. The exposition is as geometrical as possible, reflecting the original style of the ancients. The first chapter presents the general body of observational astronomy known to the ancients and forming the subject of their explanatory endeavors. Each of the following chapters concentrates on the work of a single astronomer - Eudoxus, Hipparchus, Ptolemy, Copernicus, Tycho, and Kepler - and provides biographical details, a detailed exposition of his astronomical system, and some evaluation of the astronomer's role in the history of astronomy. Theodor S. Jacobsen is professor emeritus of astronomy at the University of Washington.

Interpreting Astronomical Spectra D. Emerson Institute for Astronomy, Department of Physics and Astronomy, The University of Edingurgh "Interpreting Astronomical Spectra" describes how physical conditions such as temperature, density and composition can be obtained from the spectra of a broad range of astronomical environments ranging from the cold interstellar medium to very hot coronal gas and from stellar atmospheres to quasars. In this book the author has succeeded in providing a coherent and integrated approach to the interpretation of astronomical spectroscopy, placing the emphasis on the physical understanding of spectrum formation rather than on instrumental considerations. MKS units and consistent symbols are employed throughout so that the fundamental ideas common to diverse environments are made clear and the importance of different temperature ranges and densities can be seen. Aimed at senior undergraduates and graduates studying physics, astronomy and astrophysics, this book will also appeal to the professional astronomer.

A reconstruction of the Chinese sky of two thousand years ago, based on analysis of the first star catalogue in China and other sources. Presented in six well-sized star maps for 100 BC, it is especially important for the history of astronomy. The Han sky, with five times more constellations than Ptolemy knew, reflects diverse human activities. The way in which constellations were grouped discloses a systematic cosmology, uniting universe and the state.
The work of the three Han schools is comparable to Ptolemy's "Almagest. With three detailed Appendices on the constellations of the three schools, well illustrated to demonstrate the relation between sky and human society, this book is valuable not only for astronomy historians and sinologists, but in general for scholars interested in the ancient cultures of Asia.

There is deep mystery and profound satisfaction in finding your position on earth by reference to the sun, moon, and stars--not to mention profound relief when the GPS receiver stops working in mid-passage. That is why knowledge of celestial navigation is still a rite of initiation, and its practice still a favorite pastime among serious cruisers.

That this edition of Celestial Navigation for Yachtsmen should appear 44 years after the first British edition and 27 years after its first publication in the U.S. is eloquent testimony to the authors clear, concise explanation of a difficult skill. Through those years, Celestial Navigation for Yachtsmen has been the best-known, best-loved primer on the subject throughout the English-speaking world. It successfully teaches sailors who have been demoralized by bigger books. It remains the famous little book on celestial navigation.

Among other changes, this edition substitutes the Nautical Almanac for the Air Almanac, discusses the short tables based on H.O. 211, expands the discussion in a few areas, fine-tunes it in others, and shows how to advance a line of position for a running fix from sun sights. The only mathematics involved are straightforward addition and subtraction.

Celestial Navigation for Yachtsmen has spawned many imitators over the years, but its still the best--with this new edition more than ever.

Astronomy has never been a more popular pastime than it is today. The increased availability of less expensive, more powerful, and more sophisticated telescopes has given rise to a new generation of stargazers. And for these beginning astronomers here is the comprehensive book covering everything from the difficult task of selecting an instrument to the equally daunting choices that arise when a telescope is turned to the heavens.

Renowned British astronomer and author James Muirden takes the fledgling astronomer by the hand in his new book, offering tips on:

* the purchase, assembly, and orientation of your new telescope
* how to observe and chart the Sun, Moon, planets, stars and comets
* how to investigate the deep-sky objects -- clusters, nebulae, and other galaxies beyond the Milky Way

The final chapter, "Windows into Space," explores ten carefully selected regions featuring noteworthy examples of double stars, galaxies, and nebulae, as well as more obscure objects seldom examined by astronomers.

How to Use an Astronomical Telescope offers completely revised and updated location charts with detailed coordinates, tables, appendixes, and numerous illustrations and photographs, making it the essential volume for one's first exploration of the cosmos.

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.
