Pulverized Moon

Large clumps of material form bright arcs in the Adams ring around the planet Neptune, which is the bright crescent at lower right. These arcs, which are at the top of the picture, are named, from left to right, Fraternité, Égalité, and Liberté. The Adams ring may have formed when a collision pulverized a small moon. Some of the material may eventually coalesce to form another moon. This image was snapped by the Voyager 2 spacecraft in 1989. [NASA/JPL]
