Icy ‘rain’ from Saturn’s rings is heating the gas giant’s atmosphere

Icy “rain” from Saturn’s rings is heating the gas giant’s atmosphere, a phenomenon never seen in the solar system before, a new study suggests. 

The unexpected discovery, which came as the result of examining data collected from various space missions including NASA’s Hubble Space Telescope, the retired Cassini probe and the Voyager 1 and Voyager 2 spacecraft, could help researchers predict if exoplanets have ring systems.
