Milky Way Mapping Engine

Observed. Cataloged. Inferred. Never mixed.

Phase 4 renders the Milky Way as a clean 2D projection. This page shows anchor stars and constellation lines only, using the Phase 1 truth contract and Orion Arm scope.

What each layer means

Anchor Observed reference stars with human-known positions.

Catalog Measured stars from a bounded catalog subset.

Generated Statistical fill derived from region rules and density.

Projection

Right ascension and declination are projected into a stable 2D sky map.

Catalog stars render smaller and dimmer than anchors when enabled.

Generated stars appear as a faint statistical field and stay labeled as model output.
