NASA "Saturn’s rings are a conveniently located dynamical laboratory," says the opening sentence of a new paper. The convenient part may be debatable, but the dynamism isn't. The rings are filled with gaps and wiggles, created by interactions among their particles and a collection of small moons that act as shepherds, their gravity ushering the rings' particles into distinctive orbits. Now researchers have identified a series of bright objects embedded in the outer edge of Saturn's A Ring.
