Four interactive solar and lunar eclipse simulators. True-to-scale celestial mechanics built on NASA/JPL, ESA, NOAA and NASA Eclipse Web Site data.
A solar eclipse viewer with an interactive map: pick any point on Earth (or use your own location) and watch a realistic simulation of the sky during the eclipse — corona, Baily's beads, chromosphere, lunar shadow and more — with local circumstances, timings and the path of totality on the map.
Launch simulatorA true-to-scale 3D orbital simulation of the Sun–Earth–Moon system with automatic detection of solar and lunar eclipses. Keplerian orbits, apsidal and nodal precession, geometrically accurate shadow cones.
Launch simulatorA simulator dedicated to lunar eclipses with physical modelling of Earth's atmospheric scattering: refraction, Rayleigh scattering and ozone absorption producing the "Blood Moon" and the ozone fringe during totality.
Launch simulatorA 2D animation of how eclipses form through the year: watch the Saros cycle emerge over time from the regression of the lunar nodes and the eclipse limits.
