Inconstant Moon

Explore the Moon... discover its dramatic features and phenomena - often beautiful, sometimes bizarre, always changing. Inconstant Moon will take you on a new tour each night, with maps, photos, explanations, animations, selected links and even music!

The Moon is the most easily observable astronomical object, and also the most rewarding. For the beginner, it is a breathtaking spectacle through even a modest optical instrument, and as the knowledge and resources of the astronomer increase, it will continue to provide fascinating new challenges and insights. Inconstant Moon is intended as both an introduction to lunar astronomy for the beginner, and an ongoing reference point for the more experienced observer.
