The “Ashen Light” of Venus—a ghostly emission of light from the night side of our nearest planetary neighbor—is among the last unsolved mysteries of astronomical history. In the four centuries since the phenomenon was first reported, highly reputable visual observers of Venus have recorded seeing the Ashen Light, while others have spent a lifetime searching for it without once being convinced that they ever saw it. Is the Ashen Light a trick of the eye? The result of a defective lens? A real scientific event? Occasional references to the Ashen Light are scattered across the literature, yet no work to date has synthesized these records. This book therefore digs deep into the history of the mystery and our latest attempts to understand it, sifting through the clues that might explain whether it is caused by physics, is conjured up by the eye or brain, or a combination of both. This baffling story will appeal to amateur astronomers, hobbyists, and lay readers interested in joining the debate about one of the most elusive observable phenomena ever recorded in the night sky.

Casual stargazers are familiar with many classical figures and asterisms composed of bright stars (e.g., Orion and the Plough), but this book reveals not just the constellations of today but those of yesteryear. The history of the human identification of constellations among the stars is explored through the stories of some influential celestial cartographers whose works determined whether new inventions survived. The history of how the modern set of 88 constellations was defined by the professional astronomy community is recounted, explaining how the constellations described in the book became permanently “extinct.” Dr. Barentine addresses why some figures were tried and discarded, and also directs observers to how those figures can still be picked out on a clear night if one knows where to look. These lost constellations are described in great detail using historical references, enabling observers to rediscover them on their own surveys of the sky. Treatment of the obsolete constellations as extant features of the night sky adds a new dimension to stargazing that merges history with the accessibility and immediacy of the night sky.
Gateways Through Light and Shadow is the second book by Bryan Garner, known to his fellow ceremonial magicians as Frater Ashen Chassan, and in it we are again offered the illuminating opportunity to observe and learn from a practicing magus engaged in his Work. Once more he offers instruction in the processes of grimoric ceremonial magic and shares the insights he has gained from his ongoing research and operations. However, what may be most extraordinary about Gateways is that it allows us access to the detailed magical journal records of the communications received by Ashen Chassan and his gifted scryer, Benn mac Stiofán, during the evocations of such profound Spiritual beings as the seven Planetary Archangels, the seven Olympic Planetary Spirits, the four Spirit Kings of the Cardinal Directions, and the Supercelestial Angels Sandalphon and Metatron. Gateways Through Light and Shadow is illustrated throughout with two-color line art of the talismanic magical implements used in the evocations, including sigils, seals, lamens, pentacles, and magic circles, along with new implements created by the magician under the guidance of the Archangels, as well as new portraits of the evoked Spirits. "This book is a major contribution to the study and practice of Western ceremonial ritual magic. This is a book that no serious practitioner of magic should be without." --from the Foreword by Dr. Stephen Skinner
Structure of the Moon's Surface focuses on the importance of certain features of the Moon's surface that have frequently been disregarded in the past, largely because of lack of knowledge of them. Topics covered include the librations of the Moon; height determinations of the points on the lunar surface; luminous intensity and luminescence of the lunar rocks; the color of moonlight and composition of the Moon's surface; and the Moon's temperature and atmosphere. This book is comprised of 14 chapters and begins with a review of important physical problems associated with the Moon, including its motion and figure as well as the luminous intensity and luminescence of its rocks. The following chapters discuss the polarization of light reflected by the Moon; the problem of the Moon's atmosphere; the probable nature of the Moon's surface; and changes occurring on the Moon. The Moon's ray and grid systems, lattice patterns, rilles and faults, and distribution and frequency of craters are also considered. The final chapter is devoted to the origin of the Moon's surface. This monograph will be of use to both professional and amateur lunar astronomers.
Barry Moser's extraordinarily detailed and evocative relief engravings decorate this translation of Pliny the Younger's two famous letters to Tacitus about the eruption of Mount Vesuvius in A.D. 79 and the death of his uncle, Pliny the Elder. Printed in black and white, the engravings are works of art that illustrate various descriptions in the letters. The text includes a brief description of the eruption of the volcano, concise biographies of Tacitus and of both Plinys, and a summary of how the texts of the two letters have survived until today.
This is an informative, up-to-date and well-illustrated guide to planetary observations for amateurs. After a brief description of the solar system and a chapter on the celestial sphere, readers are shown how to choose, test and use a telescope with various accessories and how to make observations and record results. For each planet and the asteroids, details are given of observational techniques, together with suggestions for how to make contributions of scientific value. From a general description and detailed observational history of each planet, observers can anticipate what they should see and assess their own observations. The chapter on planetary photography includes the revolutionary use of videography, charge coupled devices and video-assisted drawing. There are also chapters on making maps and planispheres and on photoelectric photometry.
Part of the first generation to be conceived in deep space, fifteen-year-old Waverly is expected to marry young and have children to populate a new planet, but a violent betrayal by the dogmatic leader of their sister ship could have devastating consequences.
