Earth to the edge of the observable universe
A measured scale journey from Earth to the cataloged extragalactic field.
Start this tour- Earth as the starting scale
Earth provides the observing baseline. The atlas position is heliocentric and projected onto the ecliptic plane.
- The planetary neighborhood
At Solar System scale, planetary distances remain physical. The ruler does not compress empty space.
- Nearby stellar space
The Sun becomes one star among measured neighbors. Gaia astrometry supplies positions for the quality-selected stellar layer.
- Across the Milky Way
The map shows a top-down physical projection. Source z coordinates are retained even though this view displays x and y.
- The cataloged observable field
DESI DR1 galaxies and quasars trace its spectroscopic footprint. Quaia adds a broad quasar-candidate layer with inferred redshifts. Blank regions can reflect selection and footprint, not empty space.
