Close Up On Jupiter: The Juno spacecraft is changing how we see Earth's largest neighbor

NASA’s Juno spacecraft arrived at Jupiter in 2016, and since then it has been stunning scientists and the public with views of Jupiter unlike any seen before. Juno’s visible-light images are processed by citizen scientists and often are color-stretched to emphasize detail and contrast. These images have led to discoveries, such as the state of Jupiter’s shrinking Great Red Spot. But Juno’s other instruments have measured properties beyond the view of visible light and have produced dramatic data about the interior of the gas giant planet, as well as revelations about its gravity, radiation, and magnetic field. In “Inside Jupiter” (pages 98–105), Scott Bolton details how all of these discoveries not only tell us about our enormous neighbor but also expand our understanding of the formation of our own planet and the rest of our Solar System, and are essential to better characterizing exoplanets in other systems.
