By analyzing images taken by NASA’s Hubble Space Telescope from 2009 to 2020, researchers found that the average wind speed just within the boundaries of the Great Red Spot, set off by the outer green circle, have increased by up to 8 percent from 2009 to 2020 and exceed 400 miles per hour. In contrast, the winds near the storm’s innermost region, set off by a smaller green ring, are moving significantly more slowly. Both move counterclockwise.
