Juno Reveals the Depth of Jupiter’s Zones and Belts

Jupiter’s belts and zones represent east-west jet-streams that show a clear north-south asymmetry.

Jupiter’s gravity field shows a similar north-south asymmetry penetrating 3000 km into Jupiter.

Gravity observations reveal a deep dynamical atmosphere (~3 Earth masses) in differential rotation

This implies that the dynamical atmosphere of Jupiter is equivalent to about 3 Earth masses.

The gravity results were a surprise and indicate the origin of Jupiter’s asymmetric nature may lie deep inside of Jupiter.
