Hubble Shows Winds in Jupiter’s Great Red Spot Are Speeding Up

Summary
The Winds at the Outer Edge Are ‘Winning the Race’ in This Enormous Storm System
Listen up, race fans! The innermost lane no longer has a predictable advantage. In Jupiter’s Great Red Spot, a storm that has been roiling for centuries, the speed in its “outer lane” is moving faster than the inner lane – and continues to pick up speed. By analyzing long-term data in this high-speed ring, researchers found the winds have increased by up to 8 percent from 2009 to 2020. These findings could only be made with Hubble: The telescope has amassed more than 10 years of regular observations, acting like a “storm watcher” for the planets in our solar system.
