Scientists can learn a lot about winds from old pictures of Uranus
We now know a lot more about the weather on Uranus thanks to 24-year-old  data. A new analysis of data collected by the Voyager 2 spacecraft in  1989 revealed that while the atmosphere is full of the violent  windstorms we expected, the surface is surprisingly calm. The storms,  scientists say, are confined to a thin weather layer 680 miles deep at  most. They say this discovery could help us understand more about how  gas giant atmospheres work. Though NASA says we won't get any  information that's up to today's standards for a while, they're hoping  to learn more about the surface of gas giants from the Juno spacecraft  currently headed to Jupiter.
