Mark Showalter Quotations

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

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

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

Everything we find now is consistent with that conclusion.

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

The newly reported spiral is in a class by itself.

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.
