From the measurements of sizes and movements, we deduced that it is highly unlikely that the current Great Red Spot was the 'Permanent Spot' observed by Cassini... longevity of the Red Spot exceeds 190 years.
The planet Jupiter has a rich history of astronomical observations dating back centuries, contributing to the understanding of its unique features and phenomena like the Great Red Spot.
Robert Hooke and Giovanni Cassini, among others, made early observations of Jupiter and its spots, with the 'Permanent Spot' disappearing from records by the mid-18th century.
