Giant Planets Build Moon Factories Inside Their Disks

Jupiter has more than 100 officially recognised moons. But the four biggest are the real clue: flat, ordered, and too organised to look random.

Scientists think giant planets may not simply collect moons. They may build them inside planet-centred disks of gas, dust, and ice — moon factories that disappear after the system is finished.

This Genius Night Science documentary follows Jupiter’s Galilean moons as the familiar clue, circumplanetary disks as the mechanism, and Webb-era observations of CT Cha b as a modern glimpse of the kind of environment where large moons may form.

By the end of this video, you will understand why Jupiter’s moons are not just objects in orbit, why their order matters, and how giant planets may become moon-building systems.
