Jet Propulsion Laboratory https://www.jpl.nasa.gov/ July 22, 2020
The north pole of Ganymede can be seen in center of this annotated image taken by the JIRAM infrared imager aboard NASA's Juno spacecraft on Dec. 26, 2019. Longitudinal lines appear every 30-degrees. The thick line is 0-degrees longitude. At the time the data for this image was captured, Juno was flying in the proximity of the north pole of the Jovian moon.
