How it works
01
Roll the cosmos
One provably-fair roll a day pulls a real astronomical object from a pool of exoplanets, pulsars, comets, galaxies and more.
02
Earn science badges
Badges are minted from the object’s real properties — orbital period, spectral type, discovery year, hazard class.
03
Build your dex
Every object lands in your collection with a sky map and tonight’s visibility from where you stand.
