"There are many gaps in Saturn's rings, but so far we've only found moons in two of them: Pan in the Encke Gap and Daphnis in the Keeler Gap. Some scientists believe that there must be a moon in every gap. Why haven't we found more moons in gaps?
"Good science always starts with good questions. As Scientists for A Day you'll not only need to ask the right questions, but you'll also need to piece together the answers!"
