Io Plume Captured by JunoCam

This image of Jupiter's moon Io was taken by the JunoCam visible-light imager as NASA's Juno spacecraft flew past the Jovian moon on October 15, 2023. A plume over the location of the volcano Prometheus can be seen just standing out from the darkness on the left side of the image, just below the terminator (the line dividing day and night). https://photojournal.jpl.nasa.gov/catalog/PIA26235
