Typically Uranus is an incredibly boring place. Occasional storms, but typically nothing severe, or extreme. Scientists estimate that once every 7 years a flurry of storms will occasionally be sparked. However, that has made a recent outbreak of activity on the southern hemisphere of the giant gas planet extremely unusual.
Scientists analyzed images that the Voyager-2 spacecraft took just about 28-years ago to find a few hidden features within the gas planet that were otherwise unknown. As it turns out, there is a strange rotation pattern that previously was unseen. As it turns out, what was once considered one of the blandest planets in the solar system – might actually have some significantly raucous activity happening on it.
