Paperback. Condición: Good. Astronomy appears to us as a combination of art, science, and philosophy. Its study puts the universe into perspective, giving a sense of pleasure in its beauty, awe at its immensity, and humility at our trivial place in it. From earliest human history, man has scrutinized the night sky - and wondered and marveled. With unaided eye but perceptive mind, he recognized order in the regular appearance and movements of individual objects, such as the planets and star groups (constellations), in their rhythmic and majestic progressions across the bowl of night. Even in the present era of scientific exactitude, there remains a profound awareness of mysteries beyond our present interpretations. It is only in comparatively recent years, however, that man has recognized that it takes more than conventional astronomy to account for the beauties ofthe night sky. Radiations in the Earth's upper atmosphere provide a foreground light, the study of which has come under a new name, aeronomy. The science of aeronomy has rapidly burgeoned, and the student of the light of the night sky finds that he is involved in an interdisciplinary domain.…

Paperback. Condición: New. Print on Demand. This book examines the various components that make up the light of the night sky, which is traditionally separated into three primary sources: starlight, the zodiacal light, and airglow. The author provides a detailed look at the separation of these three components and how each can be individually measured and analyzed. The data presented in this book is based on a year's worth of systematic observations made with standardized zenith photometers at two different locations. Through a series of approximations the author effectively separates starlight, zodiacal light, and the airglow continuum. By making use of previous star count integrations, the author is also able to present a revised integrated starlight intensity map for the Milky Way. The study concludes with a particularly in-depth discussion on the galactic light, a component of the night sky that is still not fully understood. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
