GENESIS REVISED "It takes a certain amount of courage to step beyond one's day-to-day experiments and look at the big pictureand the origin of the Moon is a 'big picture' question par excellence. Perhaps it makes sense that William Hartmann, one of the two scientists who unraveled the Moons biggest mystery, is not only a scientist but also a part-time artist and science fiction writer. It took someone with an artists eye and a fiction writers speculative temperament to see the big picture. "This is a book about that big picture: the origin of the Moon, as interpreted by Hartmann and Alastair Cameron, the second patriarch of "The Big Splat. It is also about a doomed planet called Theia, and a familiar one called Earth that used to look vastly different from todays Earth. But, most of all, it is about a long lineage of intellectual voyagers who began exploring the Moon long before Neil Armstrong planted his boot into the lunar dust.

Amateur astronomy - Amateur astronomy, often called back yard astronomy in the US, is a hobby whose participants enjoy observing celestial objects. It is usually associated with viewing the night sky when most celestial objects and events are visible, but sometimes amateur astronomers also operate during the day for events such as sunspots and solar eclipses.

Visible light astronomy - Visible light astronomy encompasses a wide variety of observations via telescopes that are sensitive in the range of visible light. It includes imaging, where a picture of some sort is made of the object; photometry, where the amount of light coming from an object is measured, spectroscopy, where the distribution of that light with respect to its wavelength is measured, and polarimetry where the polarisation state of that light is measured.
