A composite image of Jupiter's north pole taken by JunoCam in 2016 and processed by citizen scientist Kevin Gill. CNN asked Gill to share some of his favorite images he's worked on from multiple space missions. Scroll through the gallery to discover more. NASA/JPL-Caltech/SwRI/MSSS/Kevin M. Gill
"Earth Beyond Rings" -- A view of Earth and the Moon as seen beyond Saturn's rings by Cassini. NASA/JPL-Caltech/SSI/CICLOPS/Kevin M. Gill
"Near IR Saturn North Pole" -- A view of Saturn's north polar vortex processed using far red/near-infrared wavelengths captured by Cassini. NASA/JPL-Caltech/SSI/CICLOPS/Kevin M. Gill
"Enceladus Plumes" -- A back-lit view of water-ice plumes at the south pole of Saturn's moon of Enceladus, and surface Saturnshine, as seen by Cassini. NASA/JPL-Caltech/SSI/CICLOPS/Kevin M. Gill
"Europa Galileo" -- A view of Jupiter's moon Europa made using images taken by the Galileo orbiter. NASA/JPL-Caltech/Kevin M. Gill
"Hale Crater Scene HiRISE" -- A computer generated view within Mars' Hale Crater made using imagery and digital terrain model data captured by the HiRISE instrument aboard the Mars Reconnaissance Orbiter. NASA/JPL-Caltech/University of Arizona/USGS/Kevin M. Gill
