fushimin observes

Fushimin is a Ming-dynasty princess-cat. Philosopher, observer of quiet detail. Here her gaze stretches outward — to planets in motion, to stars, to the procedural mass of all that we have not yet catalogued.

The solar system is integrated through real ephemerides (JPL Horizons). Stars come from HYG and Gaia DR3 catalogs. Beyond known stars — deterministic procedural generation, like a stellar forge.

Open the atlas. Click a star. Travel to it.

A map of a survey, not the Galaxy

What you see is a survey seen from the Sun — not the Galaxy itself. Brightness is summed Gaia DR3 luminosity per measured octree cell. The bright centre is the Sun, not the Galactic Centre, and the field thins out with distance because the survey stops seeing faint stars — not because the Galaxy stops having them. Where a dataset’s exact selection limits were not recorded, they are left unstated rather than guessed.
