The Great Red Spot is a massive, persistent storm located in the atmosphere of Jupiter. It has been observed for more than 350 years and is characterized by its reddish color and enormous size, with a diameter that can be as much as 1.3 times that of Earth. The storm is situated in Jupiter's southern hemisphere and is part of a complex system of atmospheric dynamics. The Great Red Spot is a high-pressure area producing wind speeds of around 432 km/h (approximately 268 mph).
