Moon Phases Poster — Vintage Science Chart | 18×24 Art Print
This moon phases poster maps all nine positions of the 29.5-day synodic lunar cycle in a single 18×24 chart — rendered in the exacting style of a 1960s museum diagram. Navy, rust, and muted gold on a cream ground. Fine engraved line work. Each phase — New Moon through Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent, and back to New — is labeled in caps serif with accurate shadow geometry. Precise enough for the astronomy nerd. Quiet enough for any wall.
Frequently Asked Questions
How many moon phases are there?
Eight named phases complete 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 displays all eight — plus a closing New Moon — in a 3×3 grid to show the cycle's continuity.
What's the difference between waxing and waning?
Waxing means the illuminated portion of the lunar disk 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 chart makes that geometry immediately legible.
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 shown here: the Moon completing one full orbit relative to the Sun, with every intermediate phase documented in sequence.
