Exploring Jupiter’s Magnetism

After a five-year journey, NASA's Juno spacecraft will make its long-anticipated arrival at Jupiter on July 4, 2016. Coming face to face with the gas giant, Juno will begin to unravel some of the greatest mysteries surrounding our solar system's largest planet, including the origin of its massive magnetosphere. A magnetosphere is the sphere of influence of a planet's magnetic field. As a planet rotates, the swirling motion of electrically conducting fluid deep in its interior drives electric currents, inducing a magnetic field. A pair of sensors aboard Juno will allow scientists to look inside Jupiter and map the structure of its magnetic field with high accuracy and observe variations in the field over time. The measurements will give scientists a better understanding about how Jupiter's magnetic field is generated. Watch the video to learn more.
