Coming to a halt, she hears a humming sound and soon she is witnessing the birth of a New Planet.Further adventures follow such as visiting the Garden of Eden and the Great Pyramids of Egypt, which Casina had always wanted to see.

Optics of the Moon presents methods for interpreting optics of surfaces on the Moon with complicated structures. For example, the book illustrates how phase-ratio techniques can lead to the detection of surface structure anomalies, describes polarimetric studies of the lunar surface and their use, and addresses many other questions relating to the regolith-like surfaces of the Moon, such as why the Moon looks like a ball at a large phase angle and like a disk in full moon, why the lunar surface has slight color variations, and why at large phase angles its polarization degree closely correlates with albedo.

Stonehenge was not an observatory used by druidical astronomer-priests. It was, instead, a monument in which the moon and the sun and the dead were joined together. In this book the author explains how people in the British Isles, four thousand or more years ago, identified life and death with the cycle of midwinter and midsummer and with the risings and settings of the sun and moon. This is why so many megalithic monuments have astronomical sightlines built into them. This book describes how astronomical customs developed in the British Isles. Unlike other works about 'megalithic astronomy' technical explanations about azimuths and declinations are kept to their simplest. The emphasis here is upon people rather than pertrubations and eclipses.
