Book Description
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.

Book Description
We have collected and analyzed 129 visual observations of the Ashen Light, the luminous glow on the dark side of Venus, made between 1954 and 1962. Spectroscopic and photometric studies attempting to detect dark side emission on Venus are reviewed and discussed in light of the visual occurrence of the glow. We have found a general increase in the geomagnetic index coinciding with the occurrence of the Ashen Light at times of inferior conjunction of Venus, which suggests that the Ashen Light is an auroral phenomena due to solar particle bombardment on the dark side of Venus. This possibility is explored in terms of the nature and characteristics of the visual Ashen Light observations and in terms of the recent Mariner V and Venera-4 data on the upper atmosphere of Venus.

Book Description
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.

Book Description
On a dare, Sammy recites the age-old chant of "Bloody Mary" into a mirror with a roll of his eyes. Unexpectedly, his body is pulled through his own bathroom mirror the very next morning. What he doesn't understand is waking up in the woods, miserably wet and lost, right before dawn. Rourke has been living in the twilight for most of his life. Once a peaceful place full of light, the lands are now dark and dangerous; filled with monsters that are more than willing to kill any who cross their paths. There is still a small glimmer of hope to be found. Like all Illume that survived when the mists fell over the lands, the self-trained swordsman is making his way to the Last City. Things change drastically when he rescues an Other from some Wolves, one of the bloodthirsty monsters in the dark. Sammy is nothing but trouble. He's annoying, argues with Rourke, and asks the most stupid questions. There is something about the Other that the swordsman just can't seem to figure out and decides to bring Sammy along with him. Together, making their way through the darkness, they follow the light.

Book Description
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

Book Description
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.

Book Description
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.

Book Description
WINNER OF THE PULITZER PRIZE • NATIONAL BESTSELLER • A searing, post-apocalyptic novel about a father and son's fight to survive, this "tale of survival and the miracle of goodness only adds to McCarthy's stature as a living master. It's gripping, frightening and, ultimately, beautiful" (San Francisco Chronicle). • From the bestselling author of The Passenger A father and his son walk alone through burned America. Nothing moves in the ravaged landscape save the ash on the wind. It is cold enough to crack stones, and when the snow falls it is gray. The sky is dark. Their destination is the coast, although they don't know what, if anything, awaits them there. They have nothing; just a pistol to defend themselves against the lawless bands that stalk the road, the clothes they are wearing, a cart of scavenged food—and each other. The Road is the profoundly moving story of a journey. It boldly imagines a future in which no hope remains, but in which the father and his son, "each the other's world entire," are sustained by love. Awesome in the totality of its vision, it is an unflinching meditation on the worst and the best that we are capable of: ultimate destructiveness, desperate tenacity, and the tenderness that keeps two people alive in the face of total devastation. Look for Cormac McCarthy's latest bestselling novels, The Passenger and Stella Maris.
