Astronomy & the Moon
Astronomy explains what is actually observable and computable: why the Moon changes phase, where eclipses are visible and how the inclined lunar orbit produces two nodes. These calculations can be connected to traditional lunar calendars without mistaking symbolism for measurement.
Use the eclipse visibility guide to distinguish a global UTC event from a local observing opportunity. Read NASA's maps and safety advice, check the actual horizon and weather, and use Galaxiora's calendar as an educational starting point.
