GalAtlas — Explore the universe of known worlds
GalAtlas is a cinematic, interactive 3D atlas of every known world beyond Earth, built on real data from the NASA Exoplanet Archive. It runs in your browser using WebGL and requires JavaScript to explore interactively.
Fly across every scale in one continuous zoom — from a single exoplanet's orbit to our Solar System, the Milky Way, and the galaxies of the cosmic web.
What's inside
- The Atlas: a 3D field of ~4,700 host stars and 6,300+ confirmed exoplanets in the solar neighbourhood, each placed by its real sky coordinates and distance — with nebulae, constellations, and overlays of real stellar groups and clusters (β Pictoris, Praesepe, the Hyades, Scorpius–Centaurus and more).
- Planetary systems: click any star to fly into its orbital map — the host star, its planets on true-to-scale orbits, and the habitable zone.
- Every world: radius, mass, temperature, planet type, orbital period, distance, host-star type, and discovery method and year.
- The Milky Way & Cosmos: zoom out to the whole galaxy, then on to the Local Group, galaxy clusters, and the cosmic web.
- Timeline, Sky map, Compare, and guided tours of exoplanet discovery from 1992 to today.
