#PPOD: The shadow is not that of Europa but a second moon (Io), which is not in this frame. Europa is slightly smaller than Earth's Moon and is tidally locked. Jupiter's Great Red Spot (GRS) is a vast cyclonic storm system about three times the size of Earth when Voyager flew by. Since 1979, the GRS has continuously shrunk, slowly changing its shape from an oval to a circle. It is now a little over the size of the Earth only. Credit: NASA / JPL-Caltech / Kevin M. Gill
Ätna, Krakatau und Eyjafjallajökull können einpacken: Karl erzählt in der neuen Folge von der vulkanisch aktivsten Welt des Sonnensystems: von Jupiters Mond Io, dessen Vulkane alles in den Schatten stellen, was wir sonst kennen. Und gerade das macht ihn interessant:
#PPOD: A massive storm, large enough to encompass most of North America, was spotted in Jupiter’s northern latitudes by NASA's Juno spacecraft on May 12. Juno is currently in its first extended mission and recently wrapped up close flybys of the Galilean moons Ganymede, Europa, and Io. Credit: NASA/JPL-Caltech/SwRI/MSSS/ @kevinmgill
TONIGHT, May 22, 2024, at 7 pm (PDT), Dr. Robert Pappalardo (NASA Jet
Propulsion Lab) will give a free, illustrated, non-technical lecture entitled:
“Europa Clipper: Exploring Jupiter’s Ocean World"
Waiting for [#JUICE ...] NASA's #Juno probe recently took images of the surface of #Europe, an icy moon of #Jupiter. And what a surprise! The #ice crust has shifted, distorted, ...
So what happened? Are these changes the result of interactions with the vast oceanic area lying beneath Europa's surface?
Dust from Jupiter's 4 inner moons are responsible for the rings of Jupiter, as shown in the graphic below.
Amalthea and its companion Thebe supply the dust which forms the thicker, disk-like "gossamer" ring. Dust is ejected into the rings as a result of impacts by small meteoroids into these small, low-gravity moons.
Amalthea orbits ~109,000 km above Jupiter's surface and has a period of about 12 hours.
Citizen scientist Gerald Eichstädt made these images using raw data from the JunoCam instrument, applying processing techniques to enhance the clarity of the images.

Dr Hodei is in love with two spheres: 1) A gas giant called Jupiter & 2) his deceased nonbinary lover turned SEAX drone: Amaranth (both depicted in the magnificent cover art by @carlydraws ). 🪐🚀🇵🇷🏳️🌈
