An unusual perspective, captured by NASA's Juno spacecraft in 2018.
Webb’s Jupiter
So this is “false color” becuase it is infrared (like all Webb images) and made from only two filters orange and cyan. However, the detail is incredible. That dot is tiny Amalthea at the left and— yes… that is Jupiter’s elusive ring. According to researcher Thierry Fouchet, “This one image sums up the science of our Jupiter system program, which studies the dynamics and chemistry of Jupiter itself, its rings, and its satellite system,”.
Ganymede Sets Behind Jupiter as Seen by Hubble
An image taken by the Hubble Space Telescope reminds us of how powerful this aging scope really is. Magnitudes sharper than the images originally sent by Pioneer as it passed by in the 1970s.
Ganymede from Juno
Some incredibly sharp images from the Juno mission of Ganymede. The first new views of this beautiful moon since Galileo. See more from kevinmgill on flickr. Also see the thread building up to these full composites in unmannedspaceflight.com.

Kind of Cool Image of Io from Juno
The brightest spot is a radiation signature, but all the rest are thought to be active volcanos on the Io surface. The moons are not a primary target of the Juno mission, but they do occasionally take a peek to try and monitor such phenomenon at Io. Later when the mission is extended, Juno will explore the full Jupiter system with its rings and moons. Multiple rendezvous are planned for Ganymede, Europa, and Io.
