Universe Atlas displays 8.4 million real stars from the Gaia DR3 catalogue and 2.6 million galaxies from the SDSS survey in a continuous zoom ranging across 43 orders of magnitude, from the cosmos to the quark.

The app runs on pure WebGPU (85 KB compressed) without a game engine, and the positions of the planets are validated through continuous integration against NASA JPL Horizons ephemerides with a tolerance of 0.2 degrees.

You can preview the total eclipse of 12 August 2026 in Iceland or go back in time 100,000 years to see the Great Bear constellation breaking up.
