NEW ORLEANS — Jupiter's Great Red Spot is not just a skin-deep beauty mark.

Instead, the iconic storm descends at least 200 miles beneath the clouds and possibly much deeper.

That is one of the latest findings of NASA’s Juno spacecraft, which passed directly over the storm in July.

Juno is designed to peer beneath the clouds of Jupiter, the solar system’s largest planet, and its observations have upended scientists’ notions of how a big ball of hydrogen ought to behave. They have not yet come up with a new understanding of Jupiter.
