A vibrant household portrait combining photos of Jupiter and three of its Galilean moons – Ganymede, Europa and Io – as seen by NASA’s Juno orbiter. The photographs had been captured by the spacecraft’s public-domain JunoCam instrument and processed by two “citizen scientists.” Kevin Gill produced the photographs of Jupiter (far proper), Ganymede (far left) and its icy neighbour Europa whereas Thomas Thomopoulos processed a picture of volcanic Io. Launched in August 2011, Juno has been orbiting Jupiter since July 2016. Knowledge collected by the JunoCam imager is out there to the general public for processing and sharing.
