{"product_id":"moon-phases-poster-vintage-cream","title":"Moon Phases Poster — Vintage Science Chart | 18×24 Art Print","description":"\u003cp\u003eThis 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.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e \u003ch3\u003eHow many moon phases are there?\u003c\/h3\u003e\u003cp\u003eEight 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.\u003c\/p\u003e \u003ch3\u003eWhat's the difference between waxing and waning?\u003c\/h3\u003e\u003cp\u003eWaxing 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.\u003c\/p\u003e \u003ch3\u003eHow long is a lunar cycle?\u003c\/h3\u003e\u003cp\u003eThe 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.\u003c\/p\u003e \u003ch2\u003eProduct Specs\u003c\/h2\u003e \u003cul\u003e\n\u003cli\u003eEnhanced Matte Paper Poster, 18×24 inches (portrait)\u003c\/li\u003e\n\u003cli\u003e189 g\/m² paper weight — substantial, gallery-quality feel\u003c\/li\u003e\n\u003cli\u003eMatte finish — no glare, frame-ready straight from the tube\u003c\/li\u003e\n\u003cli\u003ePrinted by Cosmos Press, sold via Outer Space Wear\u003c\/li\u003e\n\u003cli\u003eShips rolled in a protective tube\u003c\/li\u003e\n\u003cli\u003eDesigned for standard 18×24 frames\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cosmos Press","offers":[{"title":"Default Title","offer_id":45855275712569,"sku":"OSW-MOONPHASES-POSTER-VINTAGE-CREAM-18X24","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0788\/8525\/7273\/files\/moon-phases-poster-g-vintage.jpg?v=1779022191","url":"https:\/\/outerspacewear.co\/products\/moon-phases-poster-vintage-cream","provider":"outerspacewear","version":"1.0","type":"link"}
