Capture the night sky of the night before the rest of your life — astronomically exact, beautifully printed
A graduation is the kind of moment you can't recreate. The sky above you on that night is just as irreplaceable — and just as forgettable, unless someone captures it. Starry Memory does, with NASA-grade astronomical precision.
Graduation moments are rare. The sky above them, even rarer — every minute produces a unique alignment of stars that won't repeat for thousands of years.
Generic gifts get added to a pile. A star map of a graduation gets framed, hung, and pointed at by visitors for years. The recipient doesn't just receive a poster — they receive proof that someone noticed the date specifically enough to capture the sky of it.
Every star position is rendered from the HYG v3.0 catalogue, the same database professional astronomers use. Planet positions come from NASA JPL ephemerides — the same data feeding mission planning. The result is verifiable against any planetarium software.
Every Starry Memory order includes access to our 3D sky explorer — a unique interactive tool that lets you navigate the exact sky of your chosen date as if you were standing under the stars that night. Drag to change the angle, zoom into a specific constellation, identify every visible planet. We're the only service combining a printed poster with an immersive digital experience — not a static PDF, but a personalised planetarium for your moment.
On the custom star map market, you mainly find three categories. All-physical services delivering a printed poster between $25 and $50, with a 3-10 day delay and expensive logistics passed on to the price. Marketplaces (Etsy) where each seller has their own quality, their own delay, with no guarantee of astronomical precision. Premium digital services charging $15-30 for a file, justifying it by careful design. Starry Memory positions itself elsewhere: €3.99 for the HD digital file, delivered in 30 seconds by email, with the same astronomical precision as premium services and access to the 3D explorer included — the only service on the market to offer it. For the graduation-star-map use case, this positioning means: no compromise on quality, price divided by 5 to 10.
The digital file delivered measures 4960 × 7016 pixels at 300 DPI — equivalent to a high-definition A3+. You can print it without quality loss up to A2 (42 × 59.4 cm / 16.5 × 23.4 in), or even A1 (59.4 × 84.1 cm / 23.4 × 33.1 in) for a strong wall presence. For the graduation-star-map use case, here are our size recommendations: A4 (8.3 × 11.7 in) for a desk or small shelf; A3 (11.7 × 16.5 in) for a standard bedroom wall; A2 for a main living room; A1 for an accent wall in a high-ceiling space. On paper: 170 gsm for everyday use, 250 gsm for gallery look, matte or semi-gloss depending on the room's lighting. Online print shops typically charge between $5 and $25 depending on size.
Every star position on your graduation-star-map poster is computed from the HYG v3.0 catalogue, which combines the three reference astronomical databases: Hipparcos (European Space Agency mission, 1989-1993), Yale Bright Star Catalogue, and Gliese Catalogue. Planetary positions come from NASA Jet Propulsion Laboratory DE405 ephemerides — the same data used by mission control centres to plan interplanetary trajectories. You can verify the result with Stellarium, SkySafari, Cartes du Ciel or JPL Horizons. Precision: down to the arcsecond (1/3600th of a degree).
Yes — verify with Stellarium or any planetarium software, you'll find the same star positions, the same planets, the same moon phase.
Yes — instant digital download worldwide, including UK, US, Canada, Australia and Ireland. Premium prints ship to 14 countries with tracked delivery in 3–7 working days.
The high-resolution star map (4960×7016 px, 300 DPI) + a personalised illustrated poem generated from the brightest stars visible that night.
Digital file: 30 seconds after payment. Premium print: 3–7 working days with tracked shipping.
Yes — every order includes one free modification within 24 hours. Beyond that, we charge €1.99 per change (still making the service 5 to 10 times cheaper than competitors). For typos in the name or message, modification is free for life.
After your purchase, you receive a personal link giving access to an interactive web planetarium. You can rotate the celestial sphere, zoom into any constellation, identify every visible star with its name and magnitude. No installation required — works on smartphone, tablet or computer.
