The rings of the planet Saturn are producing their own 'rain', astronomers believe.
Experts knew there was water in the planet's upper atmosphere - but they weren't sure where it was coming from.
A recent study by Leicester University tracked electrically charged water droplets falling from the rings, onto the planet 36,000 miles below.
Scientists think this 'rain' could have a major impact on the makeup and temperature of Saturn's atmosphere.
They reckon the water droplets are pulled towards the planet by its magnetic field.
