The shadows suggest that the clumps are about 2,000 feet tall. Scientists have believed for years that the rings were about 30 feet thick, but based on the new images, scientists now think that they're more than 2 miles deep in some spots. "Isn't that the most outrageous thing you could imagine? It truly is like something out of science fiction," said Carolyn Porco, leader of the Cassini imaging team.
