Download or read book Mystery of the Ashen Light of Venus written by John C. Barentine. This book was released on 2021. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis The Ashen Light by : Joel S. Levine

Download or read book The Ashen Light written by Joel S. Levine. This book was released on 1969. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Venus by : William Sheehan

Download or read book Venus written by William Sheehan. This book was released on 2022-08-04. Available in PDF, EPUB and Kindle. Book excerpt: From the latest scientific advances to observation advice for amateur astronomers, a beautifully illustrated exploration of one of Earth’s closest neighbors. This book is a new, beautifully illustrated account of Venus, taking in the most recent research into this mysterious, inhospitable world. The book looks at the history of our observations of the planet, from early astronomy to future space missions, and seeks to shed light on many of the questions that remain unanswered, such as why Venus and the Earth—so similar in size and mass—evolved in such different directions, and how Venus acquired its dense carbon-dioxide atmosphere. Above all, Venus assesses whether life might have escaped from the oven-like temperatures at the surface and evolved to become perpetually airborne—in which case Venus may not be lifeless after all.
