Short Stuff: Saturn's Rings

This episode of Stuff You Should Know dives into the fascinating discoveries NASA made about Saturn's iconic rings thanks to the Cassini-Huygens spacecraft, which spent 13 years orbiting the planet and even flew through the mysterious gap between Saturn and its innermost ring. The hosts explore how scientists learned that Saturn's rings are actually much younger than previously thought—only around 100 million years old instead of billions—and that they're slowly raining down into Saturn's atmosphere at an astonishing rate of about ten tons per second. Along the way, they explain how researchers used incredibly sensitive measurements of the spacecraft's trajectory to calculate the mass of the rings and uncover surprising details about Saturn's atmospheric dynamics that completely changed our understanding of this gas giant's system.
