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?

This book compiles an array of interesting constellations that fell by the wayside before the IAU established the modern canon of constellations. The 16 constellations found in this volume fall into one or more of three broad categories: asterims, such as the Big Dipper in Ursa Major;

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 These lost constellations are described in great detail using historical references, enabling observers to rediscover them on their own surveys of the sky.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.
