✨🔭 Interesting news from outer space: #Cassini data plus global #MHD #simulations show that #Saturn’s cusp is not noon-centered like #Earth’s, but shifted toward the post-noon and even post-dusk sector. Xu, Yao, & Arridge et al. identify 67 cusp events and argue that rapid rotation plus internal #plasma sources fundamentally reshape Saturn’s global magnetic topology:

Today: Tutti gli uomini di Stefano De Martino, da Cassini a Ferraguzzo: "Lui ascolta tutti, poi decide di testa sua"
Stefano De Martino, in questo momento, è uno dei volti più “pesanti” della Rai. È in video ogni sera con “Affari Tuoi”, ha appena chiuso un’altra stagione molto fortunata di “Stasera tutto è possibile” e, soprattutto, guarda già al traguardo che in tv vale più di qualunque promozione: Sanremo...
All of Stefano De Martino’s team members, from Cassini to Ferraguzzo: “He listens to everyone, but then makes his own decisions.”
Stefano De Martino is currently one of the most “heavyweight” faces of Rai. He’s on screen every evening with “Affari Tuoi,” he just closed another very successful season of “Stasera tutto è possibile,” and, most importantly, he’s already looking ahead to the milestone that in TV is worth more than any promotion: Sanremo...

Nuevo modelo (Harvard, PNAS): el hexágono del polo norte de Saturno sería convección profunda rotatoria; vórtices internos moldean el jet polar. Simulaciones desde cero; código/datos públicos. https://aidoo.news/noticia/WlM2Bx

Ooo! These new sonifications are so fun -- I think Jupiter is my favorite -- what about y'all??

While orbiting #Saturn, the #Cassini probe spotted magnetic flow tubes empty of #plasma being transported toward the gas giant. Similar observations were recently made by the #Juno probe in the #Jupiter system.
Theoretical models suggest that this influx of plasma-empty magnetic flux tubes balances out an outgoing flow: in this case, the particle flows resulting from the intense volcanic activity of the moons #Io (Jupiter) and #Enceladus (Saturn) : https://www.irap.omp.eu/en/2025/10/what-goes-round-comes-around-inward-propagating-plasma-parcels-spotted-at-jupiter/
Alors qu'elle orbitait autour de #Saturne, la sonde #Cassini a repéré des tubes de flux magnétiques vides de #plasma transportés vers la géante gazeuse. De semblables observations ont été effectuées par la sonde #Juno dans le système jupitérien.
Les #modèles théoriques suggèrent que cette entrée de tubes de flux vides permet d'équilibrer un écoulement sortant: les #flux de #particules issues de l'intense activité volcanique des lunes #Io (Jupiter) et #Encelade (Saturne): https://www.irap.omp.eu/2025/10/des-tubes-de-plasma-vides-reperes-dans-la-magnetosphere-de-jupiter/
