Looking for Eruptions at Jupiter's Moon Europa
NASA's Juno mission captured this view of Jupiter's intriguing, icy moon Europa during a close pass on Sept. 29, 2022. The contrast has been enhanced to help scientists look for signs of eruptions along the limb and terminator – the dividing line between the day and night sides of the moon. None were identified. When processed this way, the image shows features on Europa's night side illuminated by sunlight reflected from Jupiter, also called Jupiter shine. Along the terminator, low-angle sunlight highlights topography on the moon's surface.
At the time the image was taken, the Juno spacecraft was 945 miles (1,521 kilometers) from Europa.
Citizen scientist Brian Swift processed the image from raw data from the spacecraft's JunoCam public engagement camera, brightening darker regions and enhancing the contrast.
JunoCam's raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing.
