(CNN) -- Everything about Jupiter is super-sized, including its colorful, turbulent atmosphere. But there's fresh evidence that one of the planet's most recognizable features, the Great Red Spot, is shrinking. NASA's Cassini spacecraft photographed Jupiter and its Great Red Spot, seen center near the equator, in 2000. The spot, which is actually an ancient monster storm that measures about three Earths across, lost 15 percent of its diameter between 1996 and 2006, scientists at the University of California, Berkeley, have found. It shrank by about 1 kilometer (about 0.6 miles) a day during that time period, said Xylar Asay-Davis, a postdoctoral researcher who was part of the study.
