How Jupiter cultivated more large moons than Saturn
The article discusses a scientific study explaining the differences in the satellite systems of Jupiter and Saturn, attributing these differences to variations in their magnetic fields. The research, conducted by a team from Japan and China, used simulations to model how Jupiter's strong magnetic field created a cavity that captured large moons, while Saturn's weaker field did not.
