The new discoveries demonstrate that Uranus has a youthful and dynamic system of rings and moons.

The new discoveries dramatically demonstrate that Uranus has a youthful and dynamic system of rings and moons. Until now nobody had a clue the rings were there, we had no right to expect them.

The newly reported spiral is in a class by itself.

That's sort of mysterious. A dust ring lasts a year or two, or a decade at most unless it's continuously replenished.

Everything we find now is consistent with that conclusion.

Uranus is one of the most chaotic and disruptive systems in the solar system.

This ring may be the telltale sign of an unseen belt of bodies a few feet to a few miles in size.

It is more evidence that our solar system is a dynamic place, somewhere very active.
