Yesterday we visited the #Volkssternwarte #Köln ✨🔭 The weather was overcast, so conditions were limited, but we were still able to observe #Jupiter and its four #GalileanMoons #Io, #Europa, #Ganymede, and #Callisto 💫

The #Voyager1 spacecraft took photos in 1979 on #ThisDayInHistory that proved the existence of #volcanoes on #Io, the innermost of the four #GalileanMoons of #Jupiter. Proximity to #Europa & #Ganymede force an orbital eccentricity that then creates tidal heating of Io's interior.
The #galileanmoons of #AstroGalaxyEarthAndSpace is here!!! I am trying a new art style, what do you like round iris or squared iris? #ganymede #callisto #io #europa #glasses #tomboy #girlygirl #digitalart #space #astronomy #moons #art #spaceart #astronomyart #solarsystem #jupiter #nonhuman #ocs

Photo of Jupiter and three of its Galilean moons with a thin line indicating the passage of a satellite. Jupiter is in the centre of the picture with the moons forming a diagonal line to the lower left. The moons in order from closest to furthest away from Jupiter are: Io, Europa, and Callisto. The fourth Galilean moon was behind Jupiter at the time. The satellite's track is also a diagonal from upper right to lower left and it touches the upper left edge of Jupiter. I had my camera set for a three second delay and was able to see the satellite enter the picture from the upper right before the shutter clicked.
A close encounter.
I was taking a picture of Jupiter and three of its Galilean moons (the fourth, Ganymede was behind the planet), when a satellite photo-bombed it

Jupiter appears as a bright disk with three visible moons nearby—Europa, Ganymede, and Callisto—shown as small points of light.
Jupiter before sunrise yesterday, built from 177 frames 🔭✨ Europa, Ganymede, and Callisto appear as pinpoints of light nearby.

Jupiter rising.
I was filming Jupiter and its Galilean moons the other morning just before sunrise when a satellite passed by.
Look to the left side of the video.
I've added a sound cue so turn your sound on.
Camera: Nikon P1000

A nearly full moon dominates the left side of the image, with Jupiter and three of its Galilean moons (Ganymede, Europa, and Callisto) visible as faint pinpricks of light to the lower right. The scene is set against a backdrop of dramatic, swirling clouds. The contrast between the bright moon and the dimmer celestial bodies is striking.

Also, don’t mind Callisto’s hair, it’s hard and I tried. :)
A Cassini spacecraft image shows Jupiter's Great Red Spot and two of its Galilean moons, Europa and Callisto. Europa is bright near the spot, while Callisto is darker near the frame edge, its brightness digitally enhanced for visibility. Both moons may harbor subsurface oceans potentially capable of supporting life.

A stunning nighttime photograph captures a full moon and the planet Jupiter shining brightly in the twilight sky, near the steeple of a church in Weikersheim, Germany. The Galilean moons of Jupiter are faintly visible as tiny points of light near the planet. The scene evokes the astronomical observations of Galileo Galilei.

At the centre Jupiter is visible like a bright star among countless other fainter stars in the night sky.
A screenshot from the App Star Walk 2 showing the planet Jupiter on the right side and the the four Galilean Moons called Europa, Ganymede, Callisto and Io in the centre of the image. The moons of Jupiter are all on his left side.
Watching #Jupiter through my binoculars I could see the four #GalileanMoons (on the left side of Jupiter) but they are not visible in this image. The binoculars only have a 10x magnification. That is enough to be able to see the moons as small dots. The other image is from the App: Star Walk 2.
A stunning Hubble Space Telescope image shows Jupiter and three of its Galilean moons (Europa, Callisto, and Io) in a rare triple-moon conjunction. The moons' different colors (white, dark brown, and yellowish) are clearly visible against Jupiter's banded clouds. Two smaller moons, Amalthea and Thebe, are also visible.

Hubble Space Telescope image of Jupiter with three of its Galilean moons (Io, Europa, and Callisto) and two smaller moons (Amalthea and Thebe) visible. The moons and their shadows are transiting across Jupiter's banded atmosphere. Europa appears white, Callisto dark brown, and Io yellowish.

This was taken on the 10/01/25. In this image you can see the shadow of Europa, one of the 4 Galilean moons on the surface of Jupiter.

New findings reveal that Io likely has no subsurface magma ocean but rather a rigid, partially molten interior much like Earth’s.
