EON separates observed catalogue objects from reconstructed structure and illustrative models. Toggle each layer.
The SDSS sample covers the survey footprint; it is not a complete sky map. Absence of a point is not absence of a galaxy.
Each journey uses real catalogue objects. You can leave a journey at any time and keep exploring.
EON is built from public scientific catalogues. No individual object is invented. Where structure is incomplete or unresolved, the visualization is explicitly labelled as reconstructed or illustrative.
