Storms on Saturn Can Have Impacts that Last for Hundreds of Years

While Jupiter has the famous Great Red Spot cyclonic storm, the other giant planets have less turbulent-looking surfaces. But they do have mighty storms all their own. According to a new study, mega-storms on Saturn can flare up every 20-30 years and have long-lasting effects that persist for centuries. The astronomers looked at Saturn's radio emissions and mapped the ammonia gas distribution. They found that the storms churn up this gas and can be used to trace when storms happened in the past.
