[#Waves and #Plasma] Numerous #moons orbit #Jupiter, including #Io, whose volcanic activity causes the ejection of #matter and the formation of a magnetized #plasma disc—or #magnetodisc—in the equatorial plane of the gas giant.
How does the plasma in this magnetodisk manage to remain in a state of #equilibrium? By emitting waves, according to a new study based on data acquired by the #Juno probe, which has been orbiting #Jupiter since 2016.

[#Juno and Jupiter's Galilean moons] In the early 2000s, #Hubble identified ultraviolet auroral signatures of three of Jupiter's four Galilean moons: Io, Europa, and Ganymede. Due to its low intensity, Callisto's signature remained elusive... until that day in September 2019: https://www.irap.omp.eu/en/2025/09/juno-identifies-the-missing-auroral-footprint-of-the-moon-callisto-at-jupiters-poles/
Congratulations to the team involved, whose study “completes our understanding of moon-planet couplings in the Jupiter system”! 👏 👍

"The results suggest that scientists should account for dams in their sea level rise projections... Global sea levels rose by 4.7 to 6.7 inches (12 to 17 cm) during the 20th century. About a 1/4 of that amount of water is behind dams, which means that depending on where you are in the world, dams will influence sea levels...
That's another thing we need to consider, because these changes can be pretty large, pretty significant..."

[#Ganymede and #Callisto: so close and yet so different] They were born in the same environment - the disk of gas and dust surrounding #Jupiter, but differ in their internal structures. What explains this divergence?
The temperatures prevailing within the accretion regions of the two icy moons are thought to be responsible for this differentiation, according to work by researchers at IRAP and @LAM_Marseille.

[#Ganymède et #Callisto : si proches et pourtant si différentes] Elles sont nées dans le même environnement - le disque de gaz et de poussière entourant #Jupiter, mais se distinguent par leurs structures internes. Comment expliquer cette divergence ?
Les températures régnant au sein des régions d'accrétion des deux lunes glacées seraient responsables de cette différentiation, d'après les travaux de chercheurs de l'IRAP et du @LAM_Marseille.

[Focus on the #EnVision mission] Why have #Venus and Earth evolved so differently? This is the question to be answered by the EnVision #SpaceMission of the European Space Agency - ESA, scheduled for launch in 2031.
To this end, the European #probe will carry several instruments - including an imaging #spectrometer, to which IRAP staff are contributing. Observations will be made in the UV and IR domains, in order to monitor temporal variations in #surface temperature and gas concentrations within the #atmosphere - and thus gain a better understanding of interactions between the Venusian atmosphere and surface.

[Focus sur la mission #EnVision] Pourquoi #Vénus et la Terre ont-elles évolué si différemment ? Telle est la question à laquelle devra répondre la #MissionSpatiale EnVision de l' European Space Agency - ESA dont le lancement est prévu pour 2031.
A cet effet, la #sonde européenne embarquera plusieurs instruments - un #spectromètre imageur notamment, auquel contribuent les personnels de l'IRAP. Des #observations seront effectuées dans les domaines UV et IR afin de suivre les variations temporelles de la température de #surface et des concentrations de gaz au sein de l'#atmosphère - et donc, de mieux comprendre les interactions entre l'atmosphère et la surface vénusiennes.

[Assistance gravitationnelle] Ce 18 février, la sonde #SolarOrbiter de l'ESA s'approchera de la surface de #Vénus, utilisant son champ de #gravité afin de modifier sa trajectoire. Objectif : pointer ses #instruments en direction des régions polaires du #Soleil.
Depuis cette #orbite, la sonde collectera de nouvelles données inédites qui permettront d'affiner notre compréhension de l'activité solaire. Info+ : https://www.esa.int/Enabling_Support/Operations/Solar_Orbiter_ready_for_close_encounter_with_Venus
