Teach with an experiment
Compare stable and unstable orbits, change a body's mass, and pause to discuss cause and effect. Save a scenario or record a short clip for your lesson.
ABOUT TUDUNI
A clearer view of our universe.
Space is full of questions. Tuduni gives you a place to explore them: change an orbit, follow a spacecraft, find the Moon in your sky, or make a visual story that explains what you discovered.

Explore ↗For your classroom, your curiosity, your next story.
Explore the sky above you
Follow a satellite's predicted orbit, compare Earth and lunar horizons, or find the Moon's live direction and phase from your own location.
Create a visual explanation
Frame a black hole, rehearse a camera move, and capture a simulation in MP4, MOV or WebM. Build a science story from an experiment you can revisit.
UNDERSTAND WHAT YOU ARE SEEING
Wonder, with the workings visible.
Tuduni Laboratory uses mutual Newtonian N-body forces, scientific units and conservation diagnostics. Satellite Explorer predicts orbits from public catalog elements using SGP4/SDP4. Sky Observatory calculates apparent celestial positions, while Live Moon uses NASA/JPL observer ephemerides.
Textures and space fabric help communicate the model. Space fabric is an illustration of influence; satellite positions are predictions. Weak-field light bending and Schwarzschild black-hole lensing have distinct assumptions, which the tools explain.
A source behind the surface.
Inspect data timestamps, model provenance, texture credits and calculation limits. Change one condition, compare the result and keep the source in view.
