Juno Captures Europa

This view of Jupiter's icy moon Europa was captured by JunoCam, the public engagement camera aboard NASA's Juno spacecraft, during the mission's close flyby on Sept. 29, 2022. The picture is a composite of JunoCam's second, third, and fourth images taken during the flyby, as seen from the perspective of the fourth image. North is to the left. The images have a resolution of just over 0.5 to 2.5 miles per pixel (1 to 4 kilometers per pixel). As with our Moon and Earth, one side of Europa always faces Jupiter, and that is the side of Europa visible here. Europa's surface is crisscrossed by fractures, ridges, and bands, which have erased terrain older than about 90 million years. Citizen scientist Kevin M. Gill processed the images to enhance the color and contrast.
