Listening to Saturn Through Its Rings

Saturn’s rings act like a natural seismograph. Gravitational vibrations from inside the planet send waves through the rings, allowing scientists to study Saturn’s internal structure without drilling or landing. Observations from Cassini showed that Saturn’s core is not solid, but extended and diffuse — changing how we understand gas giant planets. @BeyondEarthBuckleUp Image Credit: NASA/JPL #saturn #saturnrings #planetfacts #solarsystem #astronomy #spaceshorts #beyondearthbuckleup #nasa #astronomy #spacefacts
