• •Jupiter has multiple polar vortices, while Saturn has a single hexagonal vortex.
• •The 'hardness' of the gas at the vortex's base influences the surface fluid pattern.
• •Softer gas leads to multiple vortices, harder gas to a single vortex.
• •Saturn may have a more metal-enriched interior than Jupiter.

Scientists have found a potential connection between the surface fluid patterns of Jupiter and Saturn and their internal compositions, suggesting that the "hardness" of the gas at the base of the polar vortices influences the observed vortex patterns. Simulations showed that a softer gas at the vortex's base leads to multiple vortices, as seen on Jupiter, while a harder gas results in a single, large vortex like Saturn's. This research implies that Saturn may have a more metal-enriched interior with stronger stratification compared to Jupiter, adding to our understanding of gas giants.
