NASA Juno Mission Uncovers Subtle Geometric Shifts That Challenge Existing Models of the Jovian Interior

Refined measurements reveal Jupiter’s updated size and slightly flatter shape

Refined measurements reveal Jupiter’s updated size and slightly flatter shape Scientists have refined Jupiter’s size and shape using modern radio signal observations, finding the giant planet slightly smaller and more flattened than earlier estimates. Though the difference is only a few kilometres, researchers say it greatly improves models of Jupiter’s interior, gravity, and atmospheric structure, offering deeper insights into gas giant formation and evolution across planetary systems.
