A closer look

Imagine flexing your massive atmospheric storm for centuries only to slowly deflate like a sad cosmic balloon. The Great Red Spot is a high-pressure anticyclonic storm that has been raging for hundreds of orbits, but observations show its width is drastically decreasing. Once large enough to swallow multiple Earth-sized bodies, it is now shedding layers of gas at its edges. It is essentially the solar system's most dramatic midlife crisis.
