An interactive 3D astronomy explorer that moves from observational maps of Earth and the Moon to Solar System positions, nearby Gaia stars, and a Milky Way reconstruction.

Landing page captured for the 2026-09-26 issue.

For: People exploring astronomy across cosmic scales
Worth noticing: It separates 371,766 Gaia DR3 stars within 100 parsecs from a distinct Milky Way density model built from 230,000 weighted tracers.

Field notes

The Earth panel identifies NASA Global Imagery Browse Services as its imagery source and gives a position date of 2026-08-29 TDB. The stated JPL Horizons archive spans twenty years, while the page explicitly distinguishes observation-derived layers from modelled ones, including the Galactic reconstruction and reference spheres used where providers publish no imagery.
