Jupiter's Great Red Spot 300 km deep in the atmosphere: NASA

Solar system's largest storm, Jupiter's Great Red Spot has roots that penetrate about 300 km into the planet's atmosphere, data from NASA's Juno spacecraft has revealed. The storm measuring 16,000 km is 1.3 times as wide as Earth, as of April 2017. It appears to be diminishing as Voyager spacecraft found it twice the Earth's diameter in 1979, said NASA.
