The Age Gap: Sharks vs. Saturn's Rings

Saturn's rings are relatively young, estimated to be between 100 to 400 million years old, according to a new calculation based on data from the Cassini spacecraft. The influx of meteoroids erodes and affects the rings, causing them to ultimately lose cohesion and collapse. The researchers conclude that the rings are bound to be short-lived on the cosmic scale. Future missions may shed more light on the origin of these rings and what happened in Saturn's system a few hundred million years ago, which could help us understand the building blocks of life on Saturn's moon Enceladus.
