Mystery of the Ashen Light of Venus: Investigating a 400-Year-Old Phenomenon

The oldest unsolved mystery in observational astronomy. First reported in 1643, the Ashen Light is a faint glow emanating from the nighttime side of Venus that remains scientifically unexplained. This book digs deeply into the recorded history of the Ashen Light and the latest research attempting to understand it, sifting for clues to decide whether it leads to real physics or exists only in the eye (and brain) of the observer.

The Lost Constellations

A lost history of the night sky hides in plain sight. When the professional astronomy community defined a set of 88 canonical constellations in 1922, many figures shown on historical star charts were discarded. This reference is the first comprehensive work on obsolete constellations ever published. The history and iconography of 27 figures are discussed, and a finder chart is provided for each.
