# astro: differential rotation in Jupiter

<< Jupiter's atmosphere is rotating differentially, with zones and belts rotating at speeds that differ by up to 100 metres per second >>

<< The discovery by the Juno spacecraft that Jupiter's gravity field is north–south asymmetric [..] demonstrates that the observed zonal cloud flow must persist to a depth of about 3,000 kilometres from the cloud tops >>

AA << find that the deep interior of the planet rotates nearly as a rigid body, with differential rotation decreasing by at least an order of magnitude compared to the atmosphere >>

AA << expect the outer, differentially rotating region to be at least three times deeper in Saturn and to be shallower in massive giant planets and brown dwarfs >>

<< Scientists have long wondered what lies beneath Jupiter's surface. Now, using data from NASA's Juno mission, four research teams have published studies revealing incredible new information about the gas giant >>
