The night sky holds endless fascination for anyone who chooses simply to look up and observe, but with so much to see, it can be difficult to know where to start. This remarkable book introduces you to the fifty best sights in astronomy and tells you exactly how to see them. In no time at all, you will learn how to find and appreciate the Orion group of constellations; the Summer Triangle; Venus, Jupiter, and Mars; the best meteor showers; man-made satellites; star clusters; novae; variable stars; and more. Once you start gazing, you'll see that the sky really is the limit—and discovering its amazing treasures will become your lifetime passion.
The sights are presented according to the field of view necessary to see them. Your eyes and a clear night sky are all you need to view the sights in the first part of the book, before moving on to those that can be observed through binoculars and, finally, a telescope. Concise descriptions and explanations of these spectacular visual wonders will deepen your appreciation of them and spur further exploration. You will also find the essential basic information on astronomical observation you need to get started, including observing conditions, techniques, telescopes, and astronomical measurements.

n the last few years, cheap webcams have revolutionized amateur astronomy by providing a very inexpensive alternative to purpose-made astronomical CCD cameras, which use refrigerated imaging chips and are thus extremely expensive. Webcams are capable of more advanced work than 'normal' digital cameras because their simple construction makes it easy to remove the webcam's lens, allowing it to be interfaced directly to a telescope. Using a webcam is not difficult but most amateur astronomers who have tried to do this do not achieve the finest results, despite the webcam's potential. There are numerous imaging and image processing tricks and techniques, and all of them are needed to get the best results.Along with webcam technology has come simple-to-use image processing and enhancement using a PC: the most powerful technique is, 'stacking' in which the best images (out of hundreds) are selected and summed automatically to provide startlingly good results."Lunar and Planetary Webcam Userв_Ts Guide" de-mystifies the jargon of webcams and computer processing, and provides detailed hints and tips for imaging the Sun, Moon and planets with a webcam. He looks at each observing target separately, describing and explaining all specialised techniques in context.Glance through the images in this book to see just how much you can в_" easily в_" achieve by using a webcam with your telescope!

Astrochemistry as a subject has been rapidly evolving in recent years driven by theory and experimental results. It is a subject that encompasses chemistry, physics, astronomy and biology, and can be thought of as moving from the chemical make up of other atmospheres and space itself, through to the formation of organic life in the universe. It has moved very much from a subject portrayed in science fiction films to hard science. From a teaching point of view, it has the advantage of combining key elements of chemistry with physics and biology in an interesting and stimulating subject, much more appealing to the students than more traditional chemistry subjects. It could become the 'atmospheric chemistry' course of tomorrow.
Astrochemistry is a basic introduction to the chemistry and physics of atmospheres other than Earth's. It is based osecond year chemistry course and assumes some knowledge of physical and organic chemistry along with some basic physics. Little prior knowledge of biology or astrophysics is assumed. Starting with an introduction to the chemical universe, the text covers stellar, meteorite, comet and planetary chemistry, before covering prebiotic chemistry and life in the solar system. Results from the latest research have been included throughout.

The overall structure of the book is plain. Sandwiched between two chapters on the doggedness of Einstein are ten more in approximately chronological order, beginning with an ancient astronomical measurement followed by episodes from the Scientific Revolution (Copernicus through Newton), with accompanying background narratives from ancient science, telling tales revealing some quirky sides of scientists. The format is simple: every chapter constitutes more or less an essay unto itself; furthermore, each is divided into subsections, which are occasionally followed by boxed-in essays on specific peripheral topics. To preserve the integrity of the argument of each chapter while concomitantly avoiding too much duplication, I have cross-referenced relevant material from elsewhere in the book by section number, for example, “see section 2.3” means section 3 of Chapter 2. Accordingly, the book may be read in any order. So, begin browsing, perusing, reading—wherever you wish.

With information and scale as central themes, this comprehensive survey explains how to handle real problems in astronomical data analysis using a modern arsenal of powerful techniques. It treats those innovative methods of image, signal, and data processing that are proving to be both effective and widely relevant. The authors are leaders in this rapidly developing field and draw upon decades of experience. They have been playing leading roles in international projects such as the Virtual Observatory and the Grid. The book addresses not only students and professional astronomers and astrophysicists, but also serious amateur astronomers and specialists in earth observation, medical imaging, and data mining. The coverage includes chapters or appendices on: detection and filtering; image compression; multichannel, multiscale, and catalog data analytical methods; wavelets transforms, Picard iteration, and software tools.This second edition of Starck and Murtagh's highly appreciated reference again deals with topics that are at or beyond the state of the art. It presents material which is more algorithmically oriented than most alternatives and broaches new areas like ridgelet and curvelet transforms. Throughout the book various additions and updates have been made.

Describing interstellar matter in our galaxy in all of its various forms, this book also considers the physical and chemical processes that are occurring within this matter. The first seven chapters present the various components making up the interstellar matter and detail the ways that we are able to study them. The following seven chapters are devoted to the physical, chemical and dynamical processes that control the behaviour of interstellar matter. These include the instabilities and cloud collapse processes that lead to the formation of stars. The last chapter summarizes the transformations that can occur between the different phases of the interstellar medium. Emphasizing methods over results, The Interstellar Medium is written for graduate students, for young astronomers, and also for any researchers who have developed an interest in the interstell

Жизнеописание знаменитых ученых и краткая оценка их трудов.
Фалес. - Пифагор. - Платон. - Аристотель. - Гиппократ. - Феофраст. - Архимед. - Эвклид. - Аполлоний Пергейский. - Иппарх. - Плиний. - Диоскрид. - Гален. - Клавдий Птолемей и Александрийская школа.
Большинство этих имён хорошо известно любому образованному человеку. Тем более интересно узнать что-то новое о гениях науки древнего мира. Этой цели служит представленная книга французского писателя и естествоиспытателя Луи Фигье (Louis Figuier) (1819-1894), которая является одним из первых опытов обобщающего сборника, рассказывающих о жизни и творчестве великих представителей науки. Как справедливо замечает автор: "Жизнеописание светил науки… занимательно для всякой публики". К том уже "светские люди будут довольны возможностью прочесть, и в случае нужды справиться, с биографиями всех этих славных мужей, биографиями, написанными добросовестно и с некоторой заботой о литературной форме".

Reflector antennas are widely used in the microwave and millimeter wavelength domain. Radio astronomers have developed techniques of calibration of large antennas with radio astronomical methods. These have not been comprehensively described. This text aims to fill this gap. The Paraboloidal Reflector Antenna in Radio Astronomy and Communication: Theory and Practice takes a practical approach to the characterization of antennas. All calculations and results in the form of tables and figures have been made with Mathematica by Wolfram Research. The reader can use the procedures for the implementation of his/her own input data. The book should be of use to all who are involved in the design and calibration of large antennas, like ground station managers and engineers, practicing radio astronomers, and finally, graduate students in radio astronomy and communication technology.
