Jupiter

This BBC podcast episode of "In Our Time" features Melvyn Bragg and three experts—Michele Dougherty, Leigh Fletcher, and Carolin Crawford—discussing the planet Jupiter. The discussion covers Jupiter's discovery by Galileo, its composition as a gas giant, the formation and arrangement of elements including metallic hydrogen, various flyby missions like Voyager and JUICE, and its significant magnetic field. The panel also delves into Jupiter's moons, particularly Io, Europa, Ganymede, and Callisto, highlighting their unique features such as volcanic activity, subsurface oceans, and potential for habitability, as well as Jupiter's role in shaping the solar system by influencing the movement of astral debris. The episode also touches on the importance of amateur astronomers and the relevance of studying Jupiter to understand exoplanets.
