The Great Red Spot is a persistent anticyclonic storm in Jupiter's atmosphere, producing the largest in the Solar System. It is the most recognizable feature on Jupiter, owing to its red-orange color whose origin is still unknown. Located 22 degrees south of Jupiter's equator, it produces wind speeds up to 432 km/h (268 mph). Observations from 1665 to 1713 are believed to be of the same storm; if this is correct, it has existed for at least 358 years.

• The Great Red Spot is significant for a number of reasons. First, it is the largest and most persistent storm in the Solar System. Second, its long lifetime suggests that it is driven by some fundamental process in Jupiter's atmosphere. Third, its red color suggests that it is home to some unique chemistry.
• The Great Red Spot is a dynamic system, and its size and shape have changed over time. In recent years, it has been shrinking, and it is possible that it will eventually disappear altogether. However, even if it does disappear, the Great Red Spot will remain a significant feature in our understanding of Jupiter and its atmosphere.
• The Great Red Spot has been observed for at least 358 years, but it is possible that it is much older. The first known observation of the Great Red Spot was made by Robert Hooke in 1664. However, there are some reports of a similar feature on Jupiter dating back to the 17th century.
• The Great Red Spot is a fascinating phenomenon, and scientists are still learning about it. It is a reminder of the power and dynamism of Jupiter's atmosphere, and it is a window into the complex processes that drive weather on other planets.
