Overview

• Jupiter's Great Red Spot, long thought to be centuries old, is now believed to have formed about 190 years ago.
• The original storm observed by Giovanni Cassini in 1665, known as the 'Permanent Spot,' likely disappeared by the mid-18th century.
• Researchers used historical data and computer simulations to differentiate between the two storms.
• The Great Red Spot has been shrinking over time, currently measuring about 8,700 miles in diameter.
• Future studies will explore the storm's longevity and potential for further changes.
