{"dataset":{"slug":"universe-3d-scenes","title":"3D Universe Scenes","description":"The interactive 3D and Canvas scenes of the universe — the to-scale Solar System, the distance-true local stellar neighbourhood, the celestial-sphere constellations, and the descriptive Milky Way and Local Group — each with its honest coverage mode and the measured coordinates it draws on. No position, distance, or coordinate is fabricated.","version":"1.0.0","lastGenerated":"2026-06-29","license":"CC BY-SA 4.0","entityCount":5,"sources":["nasa","hyg"]},"entities":[{"id":"universe_scene:constellations","name":"Constellations on the Celestial Sphere","type":"universe_scene","domain":"science","description":"The stars of a constellation shown by their real directions on the celestial sphere — the pattern as it appears from Earth. Turn on the true-distance figures in the table and a striking fact appears: the stars of a constellation lie at wildly different distances and are not physically connected at all. The familiar shape is a line-of-sight illusion.","entryPath":"/universe-3d/constellations"},{"id":"universe_scene:local-group","name":"The Local Group","type":"universe_scene","domain":"science","description":"Our galactic neighbourhood — the Milky Way, Andromeda, Triangulum, the Magellanic Clouds, and the dozens of dwarf galaxies bound with them. The members and their relationships are drawn from the graph; their separations are given by the catalogue's descriptive scale labels, because numeric inter-galactic distances and positions are not part of the data.","entryPath":"/universe-3d/local-group"},{"id":"universe_scene:stars","name":"The Local Stellar Neighbourhood in 3D","type":"universe_scene","domain":"science","description":"The nearest stars to the Sun, plotted at their true three-dimensional positions from measured parallax distances. This is the view a two-dimensional star chart cannot give: not just where a star lies on the sky, but how far away it truly is. Drag to fly around the neighbourhood; the Sun sits at the centre.","entryPath":"/universe-3d/stars"},{"id":"universe_scene:milky-way","name":"The Milky Way","type":"universe_scene","domain":"science","description":"Our home galaxy and the Sun's place within it. The measured part of this picture — the local stellar neighbourhood — is the real 3D star field; the wider structure of the Galaxy (its disc, bulge, bar, spiral arms, halo, and centre) is presented from the galactic-structure catalogue as described components, because numeric galaxy-scale positions are not part of the data.","entryPath":"/universe-3d/milky-way"},{"id":"universe_scene:solar-system","name":"The Solar System in 3D","type":"universe_scene","domain":"science","description":"An interactive, to-scale model of the Sun's planetary system. Each orbit ring is drawn at the planet's real semi-major axis, so the true structure of the system — the crowded inner planets and the vast reaches of the outer ones — is genuine. Drag to rotate the system, scroll to zoom.","entryPath":"/universe-3d/solar-system"}]}
