Interactive exploration

Space & AstronomyBlack holes and light

If a black hole traps light, what are we actually seeing?

Inspect the real EHT observation, then choose a direction in a calculated light map. Follow its exterior path, find its source and reveal two images of one tiny patch.

Space & AstronomyRockets and propulsion

How can a rocket move when there is no air to push against?

Open a generic engine, follow what it carries and keep every bit of expelled mass in the story. Change who measures the motion, balance the thrust terms and discover what staging actually changes.

Space & AstronomyOrbits, satellites and gravity

How can falling keep a spacecraft above the ground?

Draw a velocity arrow, predict a path and compare two spacecraft on one clock. Follow a real NASA Earth map, inspect the next moment of free fall and discover why speed alone cannot make a circle.

Space & AstronomyMoon phases and eclipses

Why does the Moon seem to change shape?

Move the Moon around Earth and compare two viewpoints at once. Make a crescent, then tilt the orbit to discover why an eclipse is a special alignment.
