The Weirdness of Jupiter's Great Red Spot

Jupiter's Great Red Spot, a massive storm, has been observed for over 400 years. Despite expectations that it should have dissipated, it persists due to unique atmospheric conditions on Jupiter, such as the lack of a solid surface and vertical wind flows. The storm's color is not truly red but results from chemical reactions in its upper layers. Recent observations show the storm is shrinking, with its size decreasing significantly over the past few decades. Scientists are still investigating the reasons behind its longevity and current reduction in size.
