The discovery of a gradual acceleration in the moon's mean motion by Edmond Halley in the last decade of the seventeenth century led to a revival of interest in reports of astronomical observations from antiquity. These observations provided the only means to study the moon's 'secular acceleration', as this newly-discovered acceleration became known. This book contains the first detailed study of the use of ancient and medieval astronomical observations in order to investigate the moon's secular acceleration from its discovery by Halley to the establishment of the magnitude of the acceleration by Richard Dunthorne, Tobias Mayer and Jerome Lalande in the 1740s and 1750s. Making extensive use of previously unstudied manuscripts, this work shows how different astronomers used the same small body of preserved ancient observations in different ways in their work on the secular acceleration. In addition, this work looks at the wider context of the study of the moon's secular acceleration, including its use in debates of biblical chronology, whether the heavens were made up of aether, and the use of astronomy in determining geographical longitude. It also discusses wider issues of the perceptions and knowledge of ancient and medieval astronomy in the early-modern period. This book will be of interest to historians of astronomy, astronomers and historians of the ancient world."

Winner of the AAS 2019 Donald E. Osterbrock Book Prize for Historical Astronomy Grabbing the attention of poets, politicians and the general public alike, a series of spectacular astronomical events in the late 1800s galvanized Americans to take a greater interest in astronomy than ever before. At a time when the sciences were not yet as well established in the United States as they were in Europe, this public interest and support provided the growing scientific community in the United States with the platform they needed to advance the field of astronomy in the United States. Earlier in the 19th century comets, meteors and the discovery of the planet Neptune were all sources of inspiration to the general public. The specific events to be considered here are the total solar eclipses of 1868, 1869 and 1878 and the transits of Venus of 1874 and 1882. The available media responded to public interest as well as generating more interest. These events laid the groundwork that led to today's thriving network of American amateur astronomers and provide a fascinating look at earlier conceptions of the stars.

The rather specialized field of solar and infrared radiation measurement has become more and more important in the face of growing demands by the renewable energy and climate change research communities for data that are more accurate and have increased temporal and spatial resolution. Updating decades of acquired knowledge in the field, Solar and Infrared Radiation Measurements details the strengths and weaknesses of instruments used to conduct such solar and infrared radiation measurements. Topics covered include: Radiometer design and performance Equipment calibration, installation, operation, and maintenance Data quality assessment Methods to use measured data to estimate irradiance for any surface With a broad range of content that will benefit students and more experienced readers alike, this resource serves as a primer and technical reference that presents the basic terminology and fundamentals for resource assessment. It explores the history of solar radiation instruments and addresses direct normal, global, diffuse, and tilted measurements, as well as the characteristics of instruments used for these measurements. The authors consider methods of assessing the uncertainty of solar measurements and then cover albedo, infrared, net, and spectral irradiance measurements and instrumentation. The book devotes a section to other meteorological instruments, and another to the basics for installing and operating a solar monitoring station. Appendices include information on solar resource assessment modeling and satellite-derived irradiance, along with other useful material. This book's authors are experts who each have more than 30 years of experience developing and operating multiple measurement stations, working with industry to improve radiometry, and conducting various research projects.

"In his new book, Transit of Venus, 1631 to the Present, Dr Nick Lomb - an astronomer at the Sydney Observatpry and the author of the Australian Sky Guide - has produced what may be his most timely publication to date...Dr Lomb has cooked up both a titillating textual treat and a full-bodied visual feast, and whether his readers choose to nibble at the book meditatively or to ingest it voraciously in a single sitting, they are sure to come away licking their lips and drooling for more." - Michael E. Chauvin, The Bulletin The transit of Venus across the sun in June 2012 will be the last chance in our lifetime to see this rare planetary alignment that has been so important in history. Rich in historical detail and cutting edge science, along with practical information on how and when to view the transit, Transit of Venus is the must-have companion to this extraordinary astronomical event. From Johannes Kepler's first prediction of a transit of Venus in 1631, to Captain Cook's 1769 transit expedition to Tahiti (which led to the European settlement of Australia), and on to our 21st-century quest to find distant Earth-like planets using the transit method, astronomer Nick Lomb takes us on a thrilling journey of exploration and adventure.

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. This volume, the fourth in the Heliophysics collection, explores what makes the conditions on Earth 'just right' to sustain life, by comparing Earth to other solar system planets, by comparing solar magnetic activity to that of other stars, and by looking at the properties of evolving exoplanet systems. By taking an interdisciplinary approach and using comparative heliophysics, the authors illustrate how we can learn about our local cosmos by looking beyond it, and in doing so, also enable the converse. Supplementary online resources are provided, including lecture presentations, problem sets and exercise labs, making this ideal as a textbook for advanced undergraduate- and graduate-level courses, as well as a foundational reference for researchers in the many subdisciplines of helio- and astrophysics.

This book focuses on the most recent, relevant, comprehensive and significant aspects in the well-established multidisciplinary field Laboratory Astrophysics. It focuses on astrophysical environments, which include asteroids, comets, the interstellar medium, and circumstellar and circumplanetary regions. Its scope lies between physics and chemistry, since it explores physical properties of the gas, ice, and dust present in those systems, as well as chemical reactions occurring in the gas phase, the bare dust surface, or in the ice bulk and its surface. Each chapter provides the necessary mathematical background to understand the subject, followed by a case study of the corresponding system. The book provides adequate material to help interpret the observations, or the computer models of astrophysical environments. It introduces and describes the use of spectroscopic tools for laboratory astrophysics. This book is mainly addressed to PhD graduates working in this field or observers and modelers searching for information on ice and dust processes.

Astronomy was a popular and important part of Victorian science, and British astronomers carried telescopes and spectroscopes to remote areas of India, the Great Plains of North America, and islands in the Caribbean and Pacific to watch the sun eclipsed by the moon. Examining the rich interplay between science, culture, and British imperial society in the late nineteenth century, this book shows how the organization and conduct of scientific fieldwork was structured by contemporary politics and culture, and how rapid and profound changes in the organization of science, advances in photography, and new printing technology remade the character of scientific observation.
After introducing the field of Victorian science to the nonspecialist, the book examines the long periods of planning necessary for eclipse expeditions, and it recounts the day-to-day work of getting to field sites, setting up camp, and preparing for and observing eclipses. Operating behind the countless decisions made by scientists was a host of large-scale forces, including the professionalization and specialization of disciplines, the growth of service, and public funding for the sciences. Fieldwork also required close coordination with the many institutions and technological systems of British imperialism.
The development of imaging technologies was, of course, crucial to observations of the solar corona. Eclipse observation taxed astronomers and their cameras to their limits, and it raised new questions about the trustworthiness of imaging technologies. In the late nineteenth century, scientists shifted from drawing to photographing natural phenomena, but the shift occurred gradually, unevenly, and against resistance. Victorian astronomers had to weigh carefully the merits of human and mechanical observation, and the difficulties of solar photography highlight the inseparability of images from technologies of observation and printing.

Measurements of solar irradiance, both bolometric and at various wavelengths, over the last two decades have established conclusively that the solar energy flux varies on a wide range of time scales, from minutes to the 11-year solar cycle. The major question is how the solar variability influences the terrestrial climate. The Solar Electromagnetic Radiation Study for Solar Cycle 22 (SOLERS22) is an international research program operating under the auspices of the Solar-Terrestrial Energy Program (STEP) Working Group 1: The Sun as a Source of Energy and Disturbances'. STEP is sponsored by the Scientific Committee of Solar-Terrestrial Physics (SCOSTEP) of the International Council of Scientific Unions (ICSU). The main goal of the SOLERS22 1996 Workshop was to bring the international research community together to review the most recent results obtained from observations, theoretical interpretation, empirical and physical models of the variations in the solar energy flux and their possible impact on climate studies. These questions are essential for researchers and graduate students in solar-terrestrial physics.

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.

Eleven planetary atmospheres are included for detailed study in this reference/text, four for the giant planets (Jupiter, Saturn, Uranus, and Neptune), four for the small bodies (Io, Titan, Triton, and Pluto), and three for the terrestrial planets (Mars, Venus, and Earth). The authors have carried out a comprehensive survey of the principal chemical cycles that control the present composition and past history of planetary atmospheres, using the database provided by recent spacecraft missions supplemented by Earth-based observations.

There are several textbooks available on solar astronomy which deal with advanced astrophysical aspects of solar physics, and books which provide very elementary knowledge about the Sun. This book will help to bridge the gap. It aims to stimulate interest in solar astronomy, presenting at one place the basic methods and techniques used in the field, together with the latest findings and the excitement in solar physics. As solar astronomy is becoming very popular among amateur astronomers and laymen, the book provides the practical knowledge to build simple solar telescopes and other equipment for making solar observations. Amateur astronomers have made important contributions to solar astronomy, and this book will help to guide them in their endeavours. The book can also serve as a text for undergraduate and graduate students starting out on solar physics. Using it, graduate students can easily embark on specific topics of research in solar astronomy.

This textbook is intended to be used in a lecture course for college students majoring in Earth Sciences. Planetary science provides an opportunity for these students to apply a wide range of subject matter pertaining to the Earth to the study of other planets and their principal satellites. In this way, planetary science tends to unify subjects in the Earth Sciences that are traditionally taught separately. Therefore, planetary science is well-suited to be taught as a capstone course for senior undergraduates in geology departments and as an introduction to the solar system in astronomy departments. Both groups of students will benefit because planetary science bridges the gap between geology and astronomy and it prepares geologists and astronomers to participate actively in the on-going exploration of the solar system.

Written in a clear, friendly style, this is a truly revolutionary book about the weirdly beautiful patterns and harmonies woven around Earth by our nearest planetary neighbour, Venus.

Planetary atmospheres is a relatively new, interdisciplinary subject that incorporates various areas of the physical and chemical sciences, including geophysics, geophysical fluid dynamics, atmospheric science, astronomy, and astrophysics. Providing a much-needed resource for this cross-disciplinary field, An Introduction to Planetary Atmospheres presents current knowledge on atmospheres and the fundamental mechanisms operating on them. The author treats the topics in a comparative manner among the different solar system bodies-what is known as comparative planetology. Based on an established course, this comprehensive text covers a panorama of solar system bodies and their relevant general properties. It explores the origin and evolution of atmospheres, along with their chemical composition and thermal structure. It also describes cloud formation and properties, mechanisms in thin and upper atmospheres, and meteorology and dynamics. Each chapter focuses on these atmospheric topics in the way classically done for the Earth's atmosphere and summarizes the most important aspects in the field. The study of planetary atmospheres is fundamental to understanding the origin of the solar system, the formation mechanisms of planets and satellites, and the day-to-day behavior and evolution of Earth's atmosphere. With many interesting real-world examples, this book offers a unified vision of the chemical and physical processes occurring in planetary atmospheres.

The sun radiates a tremendous amount of energy, called solar energy or solar radiation, which is the main natural source of energy on the Earth, by far. Because solar radiation is the almost unique supplier of energy to the Earth, it has a primary influence on life and activities on the Earth. The climate is a first example, but there are many others, such as plant growth or human health, or even the design of buildings, the production of energy, notably electrical and thermal, or even aging materials. This book aims to provide simple answers to anyone who has questions about solar radiation. Its ambition is to help by presenting the fundamental elements of the solar radiation received on the ground. The book includes many examples and numerous illustrations, as well as some simple but fairly precise equations to calculate the various elements covered and to reproduce the figures and graphs. The first of the three parts of this book is devoted to the relative geometry between the direction of the sun and an observer on the ground as well as to the solar radiation emitted by the sun and received at the top of the atmosphere. The orbit of the Earth around the sun and the solar declination are described. The concept of time is introduced which is closely linked to the solar cycle and the rotation of the Earth on itself. Equations are given to calculate the solar radiation received on a horizontal or inclined surface located at the top of the atmosphere. The spectral distribution of the extraterrestrial solar radiation is described. The second part of this book addresses how the solar radiation incident at the top of the atmosphere is attenuated and modified in its downward path to the ground. The reflection of the radiation by the ground is presented. The solar radiation received on the ground by a horizontal or inclined collector plane, such as a natural slope or a rooftop, is discussed, as well as its spectral distribution. The variability of the radiation is addressed in relation to the properties of solar radiation estimated from the measurements. The third part deals with direct or indirect measurements of the solar radiation received on the ground over a given integration time (minute, hour, day, or month), whether for total radiation or radiation in a spectral range such as ultraviolet (UV), or daylight, or photosynthetically active radiation (PAR). It also explains how to check the plausibility of the measurements. Fundamentals of Solar Radiation will be a valuable resource to all professionals, engineers, researchers, students, and other practitioners that seek an understanding of solar radiation.

Several major breakthroughs in the last decade have helped contribute to the emerging field of astrobiology. Focusing on these developments, this fascinating book explores some of the most important problems in this field. It examines how planetary systems formed, and how water and the biomolecules necessary for life were produced. It then focuses on how life may have originated and evolved on Earth. Building on these two themes, the final section takes the reader on a search for life elsewhere in the Solar System. It presents the latest results of missions to Mars and Titan, and explores the possibilities of life in the ice-covered ocean of Europa. This interdisciplinary book is an enjoyable overview of this exciting field for students and researchers in astrophysics, planetary science, geosciences, biochemistry, and evolutionary biology.

What is Mars? From the ancients to the present, we have imagined Mars repeatedly and studied it longingly. As scientific knowledge of Mars has changed, so has the cultural imagination of this celestial neighbors. The earth-centered beginnings of astronomy connected the blood-red planet with the God of War. The Copernican Revolution and a later, simple mistranslation from Italian supported fantastic visions of distant Mars as the abode of life variously bizarre, ideal, or malignant. In the work of H. G. Wells and Orson Welles, in books, films, radio, and television, Mars reflected not only eternal hopes and fears but then-current political realities. In recent years, "NASA-fication" has brought Mars home, imagining the Red Planet almost as an eighth continent of Earth, a candidate for exploration and exploitation both in fiction and in fact. Rabkin weaves a chronological tale of many threads, including mythology, astrology, astronomy, literary criticism, and cultural studies. More than 60 brief chapters focus on people, events, or phenomena concerning the eternal object of curiosity, Mars. This rich series of readable, illustrated chapters can be sampled at will for the fun of discovery, read sequentially as a connected history, or enjoyed as a resource for the contemplation. Featuring over 100 illustrations, this unique examination of humanity's most storied companion serves as a resource for the study of ourselves.

These are the Proceedings of the Yohkoh 10th Anniversary Meeting, a COSPAR Colloquium held in Kona, Hawaii, USA, on January 20-24, 2002. The title of the meeting was Multi-Wavelength Observations of Coronal Structure and Dynamics. In these proceedings the many and varied advances of the dynamics solar atmosphere in the past ten years of observations by Yohkoh have been reviewed.

In September 2011, the GRAIL mission launched two unmanned spacecraft to the Moon, which entered into lunar orbit on December 31, 2011 and January 1, 2012. They orbited the Moon until December 17, 2012, when they impacted the surface near the Moon's north pole. This book contains three review articles co-authored by the GRAIL Science Team and Guest Scientists that describe the reasons for the GRAIL mission, the development of the necessary technology, and the design of the mission to acquire the most precise measurements of the lunar gravity field possible today. The book provides a detailed description of the GRAIL mission's scientific objectives, the instrumentation and its required performance, the complex simulation of the measurement system for determining the gravity field, and the innovative education and public outreach of the mission directed toward middle-school students who could select areas of the Moon for imaging with the onboard MoonKam camera system. This volume is aimed at researchers and graduate students active in solar system science and planetology. Originally published in Space Science Reviews journal, Vol. 178/1, 2013.

The eleventh COSPAR colloquium The Outer Heliosphere: The Next Frontiers was held in Potsdam, Germany, from 24-28 July, 2000, and is the second dedicated to this subject after the first one held in Warsaw, Poland in 1989.
Roughly a century has passed after the first ideas by Oliver Lodge, George Francis Fitzgerald and Kristan Birkeland about particle clouds emanating from the Sun and interacting with the Earth environment. Only a few decades after the formulation of the concepts of a continuous solar corpuscular radiation by Ludwig Bierman and a solar wind by Eugene Parker, heliospheric physics has evolved into an important branch of astrophysical research. Numerous spacecraft missions have increased the knowledge about the heliosphere tremendously. Now, at the beginning of a new millenium it seems possible, by newly developed propulasion technologies to send a spacecraft beyond the boundaries of the heliosphere. Such an Interstellar Proce will start the in-situ exploration of interstellar space and, thus, can be considered as the first true astrophysical spacecraft. The year 2000 appeared to be a highly welcome occassion to review the achievements since the last COSPAR Colloquia 11 years ago, to summarize the present developments and to give new impulse for future activities in heliospheric research.

Is SETI a genuine scientific research programme? The search for extraterrestrial intelligence (SETI) has been given fresh impetus in the last years of the 20th century following developments in space science which go beyond speculation. The evidence that many stars are accompanied by planets, the detection of organic material in the circumstellar discs of which planets are created, and claims regarding microfossils on martian meteorites have all led to many new empirical searches. Against the background of these dramatic new developments in science, David Lamb evaluates claims to the contrary, and examines recent attempts to establish contact with other intelligent life forms. He also assesses competing theories on the origin of life on earth, discoveries of former solar planets, proposals for space colonies and the consequent technical and ethical issues. Most importantly he considers the benefits and drawbacks of communication with new life forms - how we should communicate and whether we actually can.
