Since the radio signature of our own Milky Way was detected in 1931, galaxies have been observed from ultra-high energy gamma rays to long wavelength radio waves, providing fundamental insights into their formation, evolution and structural components. Unveiling the secrets of some of the best-observed galaxies, this atlas contains over 250 full-color images spanning the whole electromagnetic spectrum. The accompanying text explains why we see the component stars, gas and dust through different radiation processes, and describes the telescopes and instruments used. This atlas is a valuable reference resource on galaxies for students seeking an overview of multiwavelength observations and what they tell us, and researchers needing detailed summaries of individual galaxies. An accompanying website, hosted by the author, contains slide shows of the galaxies covered in the book.

This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Astronomical Spectroscopy for Amateurs is a complete guide for amateur astronomers who are looking for a new challenge. After a brief overview of the development of spectroscopes and an introduction to the theory of stellar spectra, the book goes on to examine the various types of spectroscopes available to amateurs. Next, practical sections address all aspects of setting-up and using various types of commercially-available and home-built spectroscopes. A final part gives detailed instructions for the design and construction of three different spectroscopes, along with the necessary design theory (minimal math). The home-made spectroscopes have performance capabilities near or equal to commercial units but are constructed using basic hand tools for a fraction of the cost! This up-to-date practical spectroscopy book will enable amateur astronomers to develop the skills and equipment needed to prepare scientifically acceptable spectra data, and to make a valuable contribution to ProAm projects.

Galaxy collisions are the key process in building galaxies, triggering the formation of stars and the build-up of heavy elements that allow the formation of planets and solar systems. This book presents the revolutionary research advances achieved in the last decade and lucidly explains the underlying dynamical processes. Galaxy Collisions takes a comprehensive trip through the visually spectacular world of galaxy collisions; investigates the interactions of stars, gas clouds, and dark matter in galaxy collisions; uses analogies and metaphors to help comprehend the bizarre world of galaxies; presents recent research results to enhance the understanding of galaxy formation and evolution; includes discoveries of minor collisions within our own group of galaxies; shows how a galaxy collision might affect a solar system, or a planet like ours

One of the first maps of Mars, published by an Italian astronomer in 1877, with its pattern of canals, fueled belief in intelligent life forms on the distant red planet—a hope that continued into the 1960s. Although the Martian canals have long since been dismissed as a famous error in the history of science, K. Maria D. Lane argues that there was nothing accidental about these early interpretations. Indeed, she argues, the construction of Mars as an incomprehensibly complex and engineered world both reflected and challenged dominant geopolitical themes during a time of major cultural, intellectual, political, and economic transition in the Western world. Geographies of Mars telescopes in on a critical period in the development of the geographical imagination, when European imperialism was at its zenith and American expansionism had begun in earnest. Astronomers working in the new observatories of the American Southwest or in the remote heights of the South American Andes were inspired, Lane finds, by their own physical surroundings and used representations of the Earth’s arid landscapes to establish credibility for their observations of Mars. With this simple shift to the geographer’s point of view, Lane deftly explains some of the most perplexing stances on Mars taken by familiar protagonists such as Percival Lowell, Alfred Russel Wallace, and Lester Frank Ward. A highly original exploration of geography’s spatial dimensions at the beginning of the twentieth century, Geographies of Mars offers a new view of the mapping of far-off worlds

The second edition of Electronic Imaging in Astronomy: Detectors and Instrumentation describes the remarkable developments that have taken place in astronomical detectors and instrumentation in recent years – from the invention of the charge-coupled device (CCD) in 1970 to the current era of very large telescopes, such as the Keck 10-meter telescopes in Hawaii with their laser guide-star adaptive optics which rival the image quality of the Hubble Space Telescope. Authored by one of the world’s foremost experts on the design and development of electronic imaging systems for astronomy, this book has been written on several levels to appeal to a broad readership. Mathematical expositions are designed to encourage a wider audience, especially among the growing community of amateur astronomers with small telescopes with CCD cameras. The book can be used at the college level for an introductory course on modern astronomical detectors and instruments, and as a supplement for a practical or laboratory class.

Все мы живем в остатках огромного взрыва, случившегося около 14 миллиардов лет тому назад и положившего начало нашей Вселенной. Однако что предшествовало этому грандиозному событию? И какова вероятность того, что помимо нашего мира где-то существуют другие? В своей популярно написанной книге физик, профессор университета Тафте (США) Алекс Виленкин знакомит читателя с последними научными достижениями в сфере космологии и излагает собственную теорию, доказывающую возможность - и, более того, вероятность - существования бесчисленных параллельных вселенных. Выводы из его гипотезы ошеломляют: за границами нашего мира раскинулось множество других миров, похожих на наш или принципиально иных, населенных невообразимыми созданиями или существами, неотличимыми от людей. Идеи Виленкина оказались настолько ясными, убедительными и в то же время революционными, что в одночасье превратили скромного кабинетного ученого в звезду популярных ток-шоу, а его книгу - в международный бестселлер, получивший колоссальный общественный резонанс.

In late 2007 the Japan Aerospace Exploration Agency placed the Kaguya/Selene spacecraft in orbit around the Moon. Like previous lunar orbiters, Kaguya carried scientific instruments to probe the Moon’s surface and interior. But it also had the first high-definition television camera (HDTV) sent to the Moon. Sponsored by the Japanese NHK TV network, the HDTV has amazed both scientists and the public with its magnificent views of the lunar surface. What makes the images much more engaging than standard vertical-view lunar photographs is that they were taken looking obliquely along the flight path. Thus, they show the Moon as it would be seen by an astronaut looking through a porthole window while orbiting only 100 km above the lunar surface. This is the view we all would wish to have, but are never likely to, except vicariously through the awe-inspiring Kaguya HDTV images. The remarkable Kaguya/Selene HDTV images are used here to create a new type of lunar atlas. Because of the unique perspective of the images each plate shows the surface in a manner that makes it visually appealing and scientifically understandable. Motomaro Shirao was a member of the Kaguya HDTV team and selected the targets for imaging. Charles Wood, an expert on lunar science and history, describes the pictures with text as informative as the images are beautiful.
