#PPOD: During its close flyby of Jupiter’s moon Io on December 30, 2023, NASA’s Juno spacecraft captured some of the most detailed imagery ever of Io’s volcanic surface. In this image, taken by the JunoCam instrument from about 1,500 kilometers above the moon, Io’s night side [left lobe] is illuminated by “Jupitershine,” which is sunlight reflected from the planet’s surface.
