In the vast solar system, contrast is the key to understanding. By juxtaposing Jupiter and Neptune, we can clearly see that despite both being gas giants with massive and persistent storms, their appearances are vastly different. Jupiter's Great Red Spot is a striking reddish-brown, likely caused by complex photochemical reactions in its upper atmosphere exposed to solar ultraviolet radiation; while Neptune's Great Dark Spot is a deep blue, believed to be caused by a hole in its upper atmosphere's methane ice clouds, exposing darker, warmer clouds below. This difference in color and shape directly reflects the differences in the two planets' distance from the Sun (resulting in different amounts of solar radiation), their atmospheric composition and vertical structure, and their internal energy-driving mechanisms. Observing them is like reading two different textbooks on planetary evolution and atmospheric physics. Standing in front of the "Jupiter & Neptune Storms" exhibit, you feel a
