Moon Phases Poster — Vintage Science Chart, Cream & Navy

This moon phases poster maps the complete 29.5-day synodic lunar cycle across nine precisely rendered illustrations — New Moon through Full Moon and back again — in a 3×3 grid that reads like a page torn from a 1960s observatory field guide. Fine engraved line work, accurate shadow geometry, and a cream, navy, rust, and muted gold palette give each phase the weight of a museum diagram. Eight named phases, one complete cycle, zero clutter. The kind of science art print that earns a permanent spot on the wall.

Frequently Asked Questions

How many moon phases are there?

Eight named phases make up the 29.5-day synodic cycle: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent. This poster shows all eight, plus a closing New Moon panel to complete the cycle — nine illustrations total in a 3×3 grid.

What's the difference between waxing and waning?

Waxing means the illuminated portion of the Moon's visible face is growing — moving from New toward Full. Waning means it's shrinking — moving from Full back toward New. The shadow rendering on each phase in this print reflects that geometry accurately.

How long is a lunar cycle?

The synodic lunar month — measured from one New Moon to the next — is 29.5 days. That's the cycle charted here: the time it takes the Moon to complete one full orbit relative to the Sun as seen from Earth.
