Juno probe provides the first 3D view of Jupiter’s atmosphere – By J. Fingas (Engadget) / Oct 30 2021
Jupiter’s wild atmosphere runs deeper than expected.
NASA’s Juno probe has provided a better, deeper look at Jupiter’s atmosphere. Researchers have produced the first 3D view of Jupiter’s atmospheric layers, illustrating how its turbulent clouds and storms work in greater detail than before. Most notably, it’s clearer how cyclones and anticyclones behave. They’re much taller than expected, with the Great Red Spot (an anticyclone) running 200 miles deep. They’re either warmer or colder at the top depending on their spin, too.
Juno helped fill out the data using a microwave radiometer that offered a peek below the clouds’ surfaces. For the Great Red Spot, the team complemented the radiometer data with the gravity signatures from two close passes. The radiometer info also showed Earth-like circulation cells in northern and souther hemispheres, not to mention ocean-like changes in microwave light.
There are still mysteries left, such as the atmospheric mass of the Great Red Spot. With that said, the 3D imagery is already producing a more cohesive picture of how jovian planets like Jupiter behave. It might not take much more effort to solve more of Jupiter’s mysteries.
