In Small Astronomical Observatories, Patrick Moore has collected descriptions of amateur and small professional observatories currently in use in Europe and America, showing how many astronomers have built their own observatory, often with effective and sometimes extraordinary improvisations to reduce the cost. There is a photograph of each, along with details of its construction and a foreword written by Patrick Moore. In addition to providing a fascinating study for its own sake, Small Astronomical Observatories offers a unique fund of ideas and practical details for anyone who wants to build an amateur or small professional observatory.

Here is a comprehensive guide for every amateur astronomer who hopes to do more than just star-gaze. If you already own an astronomical telescope and want to know how to use it to the best effect, or if you are thinking about buying one and are wondering where to start, then this is the book for you. Each chapter deals with a different topic, and each has been written by a professional or amateur astronomer who has been chosen by Patrick Moore as an expert in his speciality. Topics range from buying a telescope (or making your own), through electronic equipment and accessories, to more technical aspects such as spectroscopy and astrophotography. A companion book, "The Observational Amateur Astronomer," explains how to use a modest astronomical telescope for serious observing of the Moon, planets, stars and extragalactic objects.

Patrick Moore has pulled together a group of professional and amateur astronomers, each an expert in a particular field, to describe how to observe every category of object that is within reach of an astronomical telescope of modest size. Each chapter deals with a different class of object, covering the whole range of possibilities from the Moon, planets and stars to more specialised observations of comets, novae, and meteors. If you own - or are thinking of buying - an astronomical telescope, here is the book that will help you get the most enjoyment out of it. It also explains how best to use your telescope for proper scientific observations, for astronomy is one of the few remaining areas of science where a lot of useful work can be carried out by non-professionals. A companion book, "The " "Modern Amateur Astronomer," deals with the non-observational aspects of astronomy, from buying a telescope (or making your own), through electronic equipment and accessories, to more technical aspects such as spectroscopy and astrophotography.

On the desolate, snow-topped peak of the highest mountain in Hawaii the view of the heavens is truly breathtaking. Since the "discovery" of Mauna Kea in 1963, astronomers worldwide have been vying for the opportunity to stargaze from its vantage point. Nine domes now stand on the peak, making this the world's largest observatory complex. Each dome is the brainchild of extraordinary scientists - pioneers who, amidst fierce competition and frigid, treacherous conditions - fought for their dreams to build the largest, most magnificent telescopes on Earth. Barry Parker, award-winning science writer, relates the intriguing stories of the founding of this observatory complex and goes on to interview some of the great astronomers of our time as they work at this inspiring site. Bringing the public for the first time into the rarefied air of the control rooms, Parker describes what marvelous challenges these astronomers pursue, night after night, through these massive telescopes. Using brilliant, colorful images from the world's most powerful infrared telescopes and data taken by the enormous Keck telescope - the largest in the world - the scientists at Mauna Kea capture visions of the most distant galaxies ever seen, and use them to look deeply into our past to try to determine our future. Through imagination and genius, the scientists at Mauna Kea have made significant strides in formulating answers to the most fascinating astronomical questions. What can the exploding galaxies in the outer reaches of space tell us about our universe in its infancy? Could the enormous black holes at the cores of galaxies actually be "seeds," central to forming these vast systems of stars? Will our universe, like a dying star, come to an end, and, if so, what dramatic events will lead to this fate? Parker clearly and eloquently explains the theories of these astronomers and describes one of their most ambitious efforts-the quest of finding life in other galaxies. Parker, whose earlier work The New York Times Book Review called "physics for poets," has penned a new masterpiece. This unforgettable book evokes the excitement of living and working at this exquisite site and dares us to imagine the awesome forces that power and shape our universe.

The 1990s are proving to be a very exciting p&iod for high angular resolution astronomy. At radio wavelengths a combination of new array instruments and pow erful imaging algorithms have generated images of unprecedented resolution and quality. In the optical and infrared, the great technical difficulties associated with constructing separated-aperture interferometers have been largely overcome, and many new instruments are now operating or are being developed. As these pro grams start to produce observational results they will be able to draw extensively on the experience gained by the radio-interferometry community. Thus it seemed that the time was ripe for a meeting which would bring together workers from all wavelength ranges to discuss the details of the science and art of "Very High Angular Resolution Imaging" . While the main emphasis of Symposium No. 158 was on high resolution tech niques from the radio, mm-wave, infrared and optical bands, it also provided an opportunity for presentation of astronomical results from these techniques. As well as giving our colleagues from the Northern Hemisphere a break from midwinter, the location of the Symposium in Australia recognised the continuing development of astronomical interferometry in this country, especially the recent completion of the Australia Telescope radio array, and the progress toward com missioning of the Sydney University Stellar Interferometer. A number of the par ticipants visited these instruments during the post-symposium tour."

Small and large telescopes are being installed all around the world. Astronomers have thus acquired better access to more modern equipment; not in the least to photometers, which are very important tools for the contemporary observer. This development of higher quality and more sensitive equipment makes it very necessary to improve the accuracy of the measurements. This guide helps the astronomer and astronomy student to improve the quality of their photometric measurements and to extract a maximum of information from their observations. The book is based on the authors' observing experience, spending numerious nights behind various instruments at many different observatories.

This comprehensive work takes you on a personal tour of the universe using nothing more than a pair of binoculars. More comprehensive than any book currently available, it starts with Earth's nearest neighbor, the moon, and then goes on to explore each planet in the solar system, asteroids, meteors, comets and the sun. Following this, the reader is whisked away into deep space to explore celestial bodies including stars that are known and many sights less familiar. The final chapter includes a detailed atlas of deep-sky objects visible through binoculars. The appendices include guidance on how to buy, care for and maintain astronomical binoculars, tips and hints on using them, and detailed information on several home-made binocular mounts.

Distance determination is an essential technique in astronomy, and is briefly covered in most textbooks on astrophysics and cosmology. It is rarely covered as a coherent topic in its own right. When it is discussed the approach is frequently very dry, splitting the teaching into, for example, stars, galaxies and cosmologies, and as a consequence, books lack depth and are rarely comprehensive.

Adopting a unique and engaging approach to the subject An Introduction to distance Measurement in Astronomy will take the reader on a journey from the solar neighbourhood to the edge of the Universe, discussing the range of distance measurements methods on the way. The book will focus on the "physical" processes discussing properties that underlie each method, rather than just presenting a collection of techniques.

As well as providing the most compressive account of distance measurements to date, the book will use the common theme of distance measurement to impart basic concepts relevant to a wide variety of areas in astronomy/astrophysics.

The book will provide an updated account of the progress made in a large number of subfields in astrophysics, leading to improved distance estimates particularly focusing on the underlying physics. Additionally it will illustrate the pitfalls in these areas and discuss the impact of the remaining uncertainties in the complete understanding of the Universes at large. As a result the book will not only provide a comprehensive study of distance measurement, but also include many recent advances in astrophysics.

Covering the astronomical work achieved with telescopes of moderate size, this volume indicates how recent developments in electronics make it possible for these telescopes to cope with problems formerly attacked only by the largest instruments. Because the future accomplishments of the telescopes of moderate size should be tremendously increased, this book considers both what is being accomplished and what scientists may confidently expect to be able to do in the predictable future. In searching for an appropriate topic for the symposium, the astronomers who have contributed to this volume recognized that although much attention has been devoted in recent years to Schmidt type telescopes, radio telescopes, and very large instruments, a great deal of the useful work has been and is being carried out by conventional telescopes of moderate size. Especially in the fields of astrometry and photometry a rather large fraction of the observations are being made with telescopes within, roughly, an aperture range of twelve to forty inches. Although perhaps the most exciting or novel results will be obtained with the giant reflectors, much of our progress depends upon the unspectacular accumulation and discussion of data and, within the limits of stellar magnitude to which they are suited, the smaller instruments can contribute substantially, meriting the definitive research provided in the pages of this book. Outstanding scientists have contributed to this volume their findings in such matters as image tube development; photoelectric problems in astronomy; investigation of image detectors (sensitivity assessment, equivalent quantum efficiencies, etc.); modern computing machines capable of solving photometric problems; the Newton Lacy Pierce Photometer; the infrared technique for stellar photometry; application of the small telescope to photoelectric problems; photoelectric studies of scintillation of starlight; the upper atmosphere as discerned from studies of stellar scintillation; variable star problems, present and future; and stellar spectroscopy with the mode rate size telescope. The result is a book of vital importance to the student of astronomy who wishes to understand the advances in his field made possible by electronic progress.

Molecular line emissions offer researchers exciting opportunities to learn about the evolutionary state of the Milky Way and distant galaxies. This text provides a detailed introduction to molecular astrophysics and an array of useful techniques for observing astronomical phenomena at millimetre and submillimetre wavelengths. After discussing the theoretical underpinnings of molecular observation, the authors catalogue suitable molecular tracers for many types of astronomical regions in local and distant parts of the Universe, including cold gas reservoirs primed for the formation of new stars, regions of active star formation, giant photon-dominated regions and near active galactic nuclei. Further chapters demonstrate how to obtain useful astronomical information from raw telescope data while providing recommendations for appropriate observing strategies. Replete with maps, charts and references for further reading, this handbook will suit research astronomers and graduate students interested in broadening their skill to take advantage of the new facilities now coming online.

The interstellarum Deep Sky Atlas set a new high standard for modern celestial cartography. The same team now presents the interstellarum Deep Sky Guide, its unique observing companion. Taking an intuitive visual approach, for each spread of the Atlas, the Guide focuses on carefully selected objects, either as colored composite POSS plates or through the authors' own eyepiece sketches. They allow you to estimate the visibility of features in the telescope while planning observations. Stars and other objects in the vicinity are highlighted, so they also serve as finder charts at night. An index map on each spread allows you to quickly find each object's location in the Atlas. The interstellarum Deep Sky Guide takes all the hassle out of preparing for observing sessions - there's no need to print star charts or photos. Simply grab your Atlas and your Guide, and go observe!

This book is open access under a CC BY-NC 4.0 license. The third edition of this indispensable book in radio interferometry provides extensive updates to the second edition, including results and technical advances from the past decade; discussion of arrays that now span the full range of the radio part of the electromagnetic spectrum observable from the ground, 10 MHz to 1 THz; an analysis of factors that affect array speed; and an expanded discussion of digital signal-processing techniques and of scintillation phenomena and the effects of atmospheric water vapor on image distortion, among many other topics. With its comprehensiveness and detailed exposition of all aspects of the theory and practice of radio interferometry and synthesis imaging, this book has established itself as a standard reference in the field. It begins with an overview of the basic principles of radio astronomy, a short history of the development of radio interferometry, and an elementary discussion of the operation of an interferometer. From this foundation, it delves into the underlying relationships of interferometry, sets forth the coordinate systems and parameters to describe synthesis imaging, and examines configurations of antennas for multielement synthesis arrays. Various aspects of the design and response of receiving systems are discussed, as well as the special requirements of very-long-baseline interferometry (VLBI), image reconstruction, and recent developments in image enhancement techniques and astrometric observations. Also discussed are propagation effects in the media between the source and the observer, and radio interference, factors that limit performance. Related techniques are introduced, including intensity interferometry, optical interferometry, lunar occultations, tracking of satellites in Earth orbit, interferometry for remote Earth sensing, and holographic measurements of antenna surfaces. This book will benefit anyone who is interested in radio interferometry techniques for astronomy, astrometry, geodesy, or electrical engineering.

The gas and dust between the stars emit across the electromagnetic spectrum and are found in a range of physical conditions from diffuse plasmas to cold, dense molecules. Through their study we see how quantum processes shape the structure of our Galaxy and fluid mechanics sets the stellar mass scale. The Interstellar Medium is a very broad subject with layers of complexity, a long history and a steady flow of new results. This comprehensive yet accessible textbook provides a self-contained one-semester course for advanced undergraduate or beginning graduate students. It is written in a style that students can follow by themselves and allows instructors to use class time to go deeper into the details or show applications to current research. It makes extensive use of publicly accessible data to illustrate specific points and to encourage students to learn by performing their own analyses.

Black holes entered the world of science fiction and films in the 1960s, and their popularity in our culture remains today. The buzz surrounding black holes was and is due, in large part, to their speculative nature. It is still difficult for the general public to determine fact versus fiction as it pertains to this terrifying idea: something big enough to swallow anything and everything in close proximity, with a gravitational force so strong that nothing, including light, can escape. In the fall of 2015, scientists at the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the first sounds from black holes, brought to earth by the gravitational waves that emitted from the merging of two black holes 1.4 billion light years away in space. This confirmed the existence of gravitational waves, which Albert Einstein predicted in 1916. In the spring of 2017, physicists and astronomers who were working on the Event Horizon Telescope (EHT) project captured the first image of a black hole. This was the supermassive black hole hosted by the galaxy M87 in the constellation Virgo, 53 million light years away, and the image shows the shadow the black hole casts upon the bright light surrounding it. In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

This is the story of Bernie Mills, Chris Christiansen, Paul Wild and Ron Bracewell, members of a team of radio astronomers that would lead Australia, and the world, into this new field of research. Each of the four is remembered for his remarkable work: Mills for the development the cross type instrument that now bears his name; Christiansen for the application of rotational synthesis techniques; Wild for the masterful joining of observations and theory to elicit the nature of the solar atmosphere; Bracewell for his contribution to imaging theory. As well, these Four Pillars are remembered for creating a remarkable environment for scientific discovery and for influencing the careers of future generations. Their pursuit of basic science helped pave the way for technological developments in areas ranging from Wi-Fi to sonar to medical imaging to air navigation, and for underpinning the foundations of modern cosmology and astrophysics.

Research on massive stars is undergoing a period of rapid progress, with long-held convictions being shown to be incomplete. While these stars are relatively few in number, they are the main driver of chemical and dynamical evolution in galaxies through their stellar winds and explosive deaths in core-collapse supernovae. Furthermore the impact of massive stars is widely recognized in many areas, as they are often used as tools to interpret the conditions and processes arising in different environments. In parallel, the development of new instrumentation, analysis techniques and dedicated surveys across all possible wavelengths have delivered large amounts of exquisite new data. These data are now providing a harsh test for the current state-of-the-art theoretical calculations of massive star birth, evolution and death. IAU Symposium 329 covers these topics and is therefore an invaluable resource for researchers in the field of massive stars and their evolution.

This book comprises a fascinating collection of contributions on the Merz telescopes in Italy that collectively offer the first survey on historical large refracting telescopes in the country, drawing on original documents and photographs. It opens with a general introduction on the importance of Merz telescopes in the history of astronomy and analyses of the local and international contexts in which the telescopes were made. After examination of an example of the interaction between the maker and the astronomer in the construction and maintenance of these refractors, the history of the Merz telescopes at the main Italian observatories in the nineteenth century is described in detail. Expert testimony is also provided on how these telescopes were successfully used until the second half of the twentieth century for research purposes, thus proving their excellent optical qualities.

'fascinating' Brian Cox This is the story of citizen science. Where once astronomers sat at the controls of giant telescopes in remote locations, praying for clear skies, now they have no need to budge from their desks, as data arrives in their inbox. And what they receive is overwhelming; projects now being built provide more data in a few nights than in the whole of humanity's history of observing the Universe. It's not just astronomy either-dealing with this deluge of data is the major challenge for scientists at CERN, and for biologists who use automated cameras to spy on animals in their natural habitats. Artificial intelligence is one part of the solution-but will it spell the end of human involvement in scientific discovery? No, argues Chris Lintott. We humans still have unique capabilities to bring to bear-our curiosity, our capacity for wonder, and, most importantly, our capacity for surprise. It seems that humans and computers working together do better than computers can on their own. But with so much scientific data, you need a lot of scientists-a crowd, in fact. Lintott found such a crowd in the Zooniverse, the web-based project that allows hundreds of thousands of enthusiastic volunteers to contribute to science. In this book, Lintott describes the exciting discoveries that people all over the world have made, from galaxies to pulsars, exoplanets to moons, and from penguin behaviour to old ship's logs. This approach builds on a long history of so-called 'citizen science', given new power by fast internet and distributed data. Discovery is no longer the remit only of scientists in specialist labs or academics in ivory towers. It's something we can all take part in. As Lintott shows, it's a wonderful way to engage with science, yielding new insights daily. You, too, can help explore the Universe in your lunch hour.
