When we look at Saturn, we see a pale gold sphere framed by a luminous disk that appears completely solid and permanent. This episode explores the reality behind that illusion, revealing that this 175,000-mile-wide structure is only about thirty feet thick—a proportion so delicate that it is the flattest known structure in the universe.
