The Story of the Solar System: Inside the rings of Saturn

Flying into the rings of Saturn reveals what they are made of: a rubble of ice, rock and dust, ranging in size from a small house to a grain of sand.

This is one of the last images of Saturn’s rings taken by NASA’s Cassini spacecraft, on 13 September 2017. Data from the mission is enabling scientists to learn more about the planet, its moons and its rings. Image Credit: NASA/JPL-Caltech/Space Science Institute
