Superbly illustrated, up-to-date, expanded version of Hartung's indispensable guide, useful to amateur and expert observers.
1,001 Celestial Wonders is a guide to the night sky's brightest and most fascinating objects. Each target is accessible to amateur astronomers using medium-sized telescopes from a dark site. In fact, many are so bright they remain visible under moderate light pollution, as from the outskirts of a city or the suburbs of a town. The book provides a chronological target list, making it easy to use. No matter what night you choose, this book will show you many of the most memorable objects to observe, whether you are using a small telescope or even binoculars, or an instrument of larger aperture. This is far more than just a list of interesting objects. It is structured so that objects of various observing difficulty are included, which will help readers become better observers, both encouraging beginners and challenging long-time amateur astronomers. This book is designed to be easy-to-use at the telescope, and observers will appreciate each object's standardized layout and the book's chronological organization. Finally, many amateur astronomers function best when presented with a list! Even the Meade Autostar® controller features a 'best tonight' list (although the list is far less comprehensive and detailed than the catalog provided in this book), a feature that has proved extremely popular. 1,001 Celestial Wonders offers a life-list of objects any observer would be proud to complete.
This book offers a reappraisal of basic aspects of Aristotelian cosmology. Aristotle believed that all celestial objects consist of the same substance that pervades the heavens, a stuff unlike those found near the center of the cosmos that compose us and everything in our immediate surroundings. Kouremenos argues that, contrary to the received view, Aristotle originally introduced this heavenly stuff as the matter of the stars alone, the remotest celestial objects from the Earth, and as filler of the outermost part of the heavens, forming a diurnally rotating spherical shell whose fixed parts are the stars, the crust of the cosmos which has the Earth at its center. The author also argues that, contrary to another common view, at no point in the development of his cosmological thought did Aristotle believe the heavens to be structured according to the theory of homocentric spheres developed by his older contemporary Eudoxus of Cnidus, in which the other celestial objects, the five planets known in antiquity, the Sun and the Moon, were hypothesized to move uniformly in circles, as if they were fixed stars.
The aim of this book is to demonstrate to a wider audience, as well as to a more skilled audience, the many fascinating aspects of modern celestial mechanics. It sets out to do this without the use of mathematics. After giving the reader the technical tools needed for a basic understanding of the underlying physical phenomena (using only elementary mathematics), facts and figures are provided on historical events, modern discoveries and future applications. Contents are divided into major topics where the three "souls" of modern celestial mechanics (dynamical systems, Solar System and stellar systems, spaceflight dynamics) play a major role.
Vols. for 1871-76, 1913-14 include an extra number, The Christmas bookseller, separately paged and not included in the consecutive numbering of the regular series.
