Jupiter’s Great Red Spot Shrinks and Grows

Jupiter, a gas giant, shares elements with stars but lacks the mass to ignite. Its swirling gases create colorful cloud bands and the Great Red Spot, a massive storm persisting for over a century. Recent studies show the spot is shrinking and changing color, but not spinning faster. Instead, it's getting taller, akin to a spinning clay pot. Once able to fit three Earths, it now fits just over one. These insights come from NASA missions like Voyager, Hubble, and Juno, with hopes for more discoveries.

What analogy is used to describe the behavior of the Great Red Spot as it changes?
