Space and astronomy simulations
Astronomy in canvas. Eight planets at compressed orbits, a Schwarzschild lens that warps the starfield, an accretion disk with Doppler beaming, meteors trailing through atmosphere.
4 simulations
- Black holeKeplerian particles spiral into an accretion disk; foreground gets stretched and swallowed, background galaxies stay put. Click fires polar jets.
- Gravitational lensingInverse ray-tracing through a Schwarzschild deflection — the cursor is the lens, distorting a starfield. Click stacks a mass pulse.
- Meteor showerMeteors streak diagonally toward a horizon silhouette. Cursor casts an atmosphere bubble that ignites them; click launches a large meteor.
- Solar systemEight planets at compressed orbits seeded from J2026.0; Earth's moon, Saturn's ring. Cursor x scales angular velocity; y tilts the plane.
