NASA'S Juno probe scanned this near IR false color photo during its ninth orbit around Jupiter. The depth and detail is unprecedented. At roughly ten miles per pixel, the image shows shadows being cast on the lower cloud decks by the grotesquely turbulent storms atop them.
What it doesn't tell is the range and intensity of the physical conditions it encompasses- the lowest depths of Jupiter's visible atmosphere experience pressures higher than the Earth's deepest oceans , and still deeper, but far from the gas giant's center, they surpass the temperature of the center of the earth.
Before long, a full pelt Jovian climate model will have to handle the hydrodynamics not just of cold gases but incandescent supercritical metallic hydrogen, and Lord knows what other pressure degenerate and metallically conductive molecular species coexist with it in the ocean of complexly alloyed supercritical fluids convecting and swirling in the depths below what this image reveals. It took decades of effortto produce the meerest speck of metallic hydrogen in a Harvard lab last year, and it only lasted for a few weeks before the diamond anvils compressing it to five million atmospheres exploded as a laser probed its optical properties.
Earthly climate modeling isn't easy, but the Jovian GCM builders have harder work in store- to understand the components of the atmosphere they are trying to model, their experimentalist colleagues must advance to even more daunting pressures and temperatures in the lab.
