Space Simulator Online is a free, zero-install 3D astronomy simulator that runs in any modern browser using raw WebGL2 and WebGPU (no plugins, no sign-up, no ads). Explore a real-time 3D solar system with planets, moons, asteroids, comets and spacecraft orbits; a 3D map of 6,000+ confirmed NASA exoplanets; a TESS "Planet Hunter" lab with real transit light curves; WebGPU galaxy collisions; LIGO gravitational-wave visualizations; and cosmic sounds. Available in 10 languages. I built it myself as a solo project.
