NASA probe shows multiple storms over Jupiter's North Pole
NASA's Juno spacecraft has revealed a giant cyclone over Jupiter's North Pole with eight smaller cyclones circling it. Another image depicted a cyclone over South Pole surrounded by five cyclones of diameters up to 7,000 km, suggesting polar asymmetry in magnetic fields. The central storm may contain a core of high-pressure, high-temperature rocks and perhaps water, said a project scientist.
