Jupiter’s Great Red Spot Feeds on Smaller Storms

A flake of red peels away from Jupiter’s Great Red Spot during an encounter with a smaller anticyclone, as seen by the Juno spacecraft’s high resolution JunoCam on 12 February 2019. Although the collisions appear violent, planetary scientists believe they are mostly surface effects, like the crust on a crème brûlée.

The massive storm near the gas giant’s equator has been shrinking, but collisions with a series of anticyclones are likely only surface deep. The smaller storms cause chunks of red clouds to flake off, shrinking the larger storm in the process. But the new study found that these disruptions are “superficial.” They are visible to us, but they are only skin deep on the Red Spot, not affecting its full depth.

The ne...
