A new study reveals that Saturn has long-lasting megastorms with impacts deep in the atmosphere that persist for centuries. The study helps explain the differences between storms on Saturn and Jupiter.
Megastorms regularly appear on Saturn , marring the relatively bland surface before disappearing. But radio observations show that the storms have long-lasting effects deeper in the atmosphere, in particular in the distribution of ammonia. Using NRAO's Very Large Array, astronomers see such impacts from storms that happened hundreds of years ago. The findings will help explain the differences between storms on the gas giants Saturn and Jupiter .
The largest storm in the solar system, a 10,000-mile-wide anticyclone called the Great Red Spot, has decorated Jupiter's surface for hundreds of years. A new study now shows that Saturn -- though much blander and less colorful than Jupiter -- also has long-lasting megastorms with impacts deep in the atmosphere that persist for centuries. The study was conducted by astronomers from the University of California, Berkeley, and the University of Michigan, Ann Arbor, who looked at radio emissions from the planet, which come from below the surface, and found long-term disruptions in the distribution of ammonia ga

Right now, it is late summer on Saturn’s northern hemisphere, so again, just like Earth is currently heading for northern autumn equinox in September, Saturn is … Continue reading 'The Seasons on Saturn are Changing.
