Spectacular Jupiter The Juno spacecraft is revealing a new Jupiter to us—with roiling north and south polar storms, a “fuzzy” planetary core, a “lumpy” magnetic field, and more. As this magazine went to press, Juno flew over the Great Red Spot and the data gleaned there will surely change our ideas about this iconic Jovian feature. Jupiter’s unexpectedly storm-congested south pole is highlighted in this JunoCam image captured on May 19, 2017, from a height of 49,900 kilometers (about 29,000 miles).
