The Cassini spacecraft's observations of Saturn's rings revealed that they are remarkably clean, consisting mainly of pure water ice with only minimal contamination from cumulative micrometeoroid impacts. This led to the conclusion that the rings are extremely young (about 100 million years old), which is significantly younger than the age of our solar system (~4.6 billion years). In this talk, I will challenge this common understanding.
