Explorers Moon Adventure

Explore the eight main lunar phases, learn why the Moon appears to change shape, and practice safe sky observation.

Moon science: Earth’s shadow does not normally create the Moon’s phases. Phases happen because we see different portions of the Moon’s sunlit half as the Moon orbits Earth. Earth’s shadow causes a lunar eclipse.

—Calculated illumination

—Age since new moon

—Cycle position

The live phase uses a compact astronomical Sun–Moon position calculation. It is suitable for learning and everyday moonwatching; professional rise/set and eclipse work uses full ephemerides.
