Jupiter's Great Red Spot Shrinks and Grows

Take a tour of Jupiter's dynamo, the source of its giant magnetic field, in this new global map from the Juno mission. Watch this video on the NASA.gov Video YouTube channel. Jupiter's northern hemisphere contains an area of positive magnetic flux (red) offset from the geographic north pole by approximately 45 degrees. Jupiter's southern hemisphere predominantly contains areas of negative flux (blue). Jupiter magnetic field map with contours indicating field strength and positive or negative flux. Jupiter magnetic field map without contours. Jupiter magnetic field map with longitude and latitude marked in 30 degree increments. Jupiter magnetic field map without the planetary texture. A map of Jupiter's visible surface. NASA’s Juno mission has provided the first view of the dynamo, or engine, powering Jupiter's magnetic field. The new global portrait reveals unexpected irregularities and regions of surprising magnetic field intensity, including one already playfully known as the Great Blue Spot. Red areas show where magnetic field lines emerge from the planet, while blue areas show where they return. As Juno continues its mission, it will improve our understanding of Jupiter's complex magnetic environment. Learn more about Juno's observations, and the new map of Jupiter's magnetic field.
