Does Jupiter Have A Solid Core?
The mystery of Jupiter's core is one that astronomers hope to solve with the Juno mission, which should arrive at the gas giant in July 2016. Gravitational measurements suggest that Jupiter has a center anywhere between 12 and 45 times the mass of our own planet. Because planetary formation seems to require a rocky or icy core at the outset, it's probable that Jupiter had such a core at one time. Whether it still has a rocky core, a molten core, or no core at all today is up for debate. Research also suggests that the core region is surrounded by a liquid metallic hydrogen, which is capable of conducting electricity.
