Ah, because what we really need in 2023 is a deep dive into Jupiter's "mushballs" — sounds like a bad sci-fi dessert! 🍨 Apparently, it's crucial we know that the gas giant is just a cosmic slushie with an identity crisis. 🌌🤦‍♂️

ScienceDailyOn Jupiter, it's mushballs all the way downObservations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real process associated with fierce lightning storms: strong updrafts generate slushy, ice-coated hailstones of ammonia and water that eventually plunge into the planet and deplete areas of ammonia. This is part of the first 3D picture of the planet's atmosphere, which shows storms are primarily shallow.

Der Astronom Simon #Marius (1573–1624), der zeitgleich mit Galilei die vier großen Monde des #Jupiter entdeckte, wird mit einer Botschaft aus dem All geehrt: simon-marius.net/blog/?p=245 - der Satellit #QUBE der Würzburger Forschungsfirma „Zentrum für Telematik“ (ZfT) sendet in seinen freien Minuten zwischen 17. und 23. April in regelmäßigen Abständen eine Passage aus dem Hauptwerk von Simon Marius, „Mundus Iovialis“ (Die Jupiterwelt), wo dieser seine Beobachtung des Jupitersystems vorstellt.

arXiv.orgThe Tropical Atmosphere of Jupiter - Shallow Weather, Deep Plumes, and VorticesTowering storms, swirling clouds, and vortices are the cloud tops manifestation of complex weather systems shaping the atmosphere of Jupiter. We use observations from Juno's MicroWave Radiometer (MWR), the Very Large Array (VLA) and the Hubble Space Telescope (HST) to probe for the first time the depth and impact of weather on Jupiter. We use ammonia, the main source of opacity at radio wavelengths on Jupiter, as the tracer for the weather by fitting ammonia anomalies to the MWR brightness temperature variations. We show that the majority of the weather on Jupiter is confined to regions where the clouds are forming. Both the South Equatorial Belt and the Equatorial Zone have surprisingly shallow weather systems (P < 2 bar), and even in the North Equatorial Belt most of the ammonia variations is above the water condensation level (P ~ 6 bar). This confirms that the water condensation layer plays a crucial role in controlling the dynamics and the weather on Jupiter. However, the shallow nature of the weather cannot explain the deep-seated depletion down to 30 bar that the Juno mission has revealed. We do find three features, however, that extend below the water condensation layer: a vortex in the northern hemisphere reaching down to 30 bar, an ammonia plume down to 20-30 bars, and the signature of precipitation down to 20 bar. This work highlights the interplay of large-scale processes (vortices, plumes) and small-scale processes (storms) are responsible for shaping the atmospheric makeup of Jupiter.

💁🏻‍♀️ ICYMI: Did you know planets without tectonic plates still experience "earthquakes"? It's fascinating how seismic activity works across our solar system. 🪐🌋

#Venus has volcanic tremors, while #Mars quakes as its core cools. #Jupiter's moon Io is our favorite example—with 400 active volcanoes, it's constantly shaking from Jupiter's immense gravitational forces pulling on its crust.
