Juno looks into the Great Red Spot

Juno passed about 5,600 miles (9,000 km) above the clouds of the Spot on 10 July 2017.

Scott Bolton: “For hundreds of years scientists have been observing, wondering and theorizing about Jupiter’s Great Red Spot. Now we have the best pictures ever of this iconic storm.”

The live claim is not a molten Earth in those pictures. Extra mass, if it exists, would sit under the weather. See The Spot.
