Discover the sky.
SkyLabs Cards™ is a growing set of physical astronomy cards. Each front is a text-free view of a real object; the code on the back reveals what you were looking at, and why it matters.
The decks
Constellations Series
88 cards · Edition 1.0
Every constellation the IAU recognises, one card each. The front is a text-free star field — the name is yours to work out. Scan the code to check yourself and read the science.

Nebulae
100 cards · Edition 1.0
One hundred nebulae, from the Lagoon to the Horsehead. Each front is drawn from the object's own recorded silhouette rather than a shared template, so no two fronts look alike.

- 01
Draw a card
Each card shows an unlabelled view of a real astronomical object, printed like a playing card.
- 02
Scan the code
Every card carries a QR code on the back. It opens a stable, permanent URL — no app to install.
- 03
Meet the object
The page reveals the name, its key stars or catalogue facts, and how to find it in the sky.
No names on the front
A card front is pure astronomy: a star field, a silhouette, one visual clue. Nothing is labelled. The answer lives behind the QR code, so the deck works as a game before it works as a reference.
Six fronts from the decks. Tap one to see the answer.
