Scott Bolton, principal investigator for NASA's Juno mission, dives into the latest discoveries about Jupiter’s moons Ganymede, Europa, and Io. They discuss the data collected by the spacecraft, including the presence of an ice crust meeting a subsurface ocean, and the importance of studying these moons. Excitement builds for exploring IO, the most volcanic body in the solar system, and its interactions with Jupiter's magnetic field. They also cover observations of the poles on IO, Jupiter, Ganymede, and Europa, revealing unknown volcanic activity and polar cyclones.
