Thunderstorms are a powerful force of nature, but the ones we experience on Earth are dwarfed by the ones on the gas giant planet Saturn. They are huge and can be larger than Earth itself, and now scientists think they know why they tend to appear most prominently every 20-30 years, encircling the entire planet with intense lightning and massive cloud disturbances.
Saturn’s rings are one of the most beautiful sights in the solar system. They are an amazing planetary phenomenon – countless bits of rock, ice and dust orbiting the planet in relatively paper-thin rings, which, when seen from above, kind of look like a giant vinyl record (remember those?). Saturn’s many moons can affect the rings’ appearance due to their gravitational pull. Now, new research shows how Saturn itself can do this also, essentially “shaking” its rings.
