Two sets of photos of Jupiter and Saturn. The top images, being less distinct, were taken by the Pioneer 11 mission in the 1970's. The bottom two were taken decades later, and show much greater detail, by the Cassini mission.
The difference in technology between generations of space probes can be stunning! The top two photos of Jupiter and Saturn were taken by Pioneer 11 in 1974 (Jupiter) and 1979 (Saturn); the bottom two were taken by Cassini in 2000 (Jupiter) and 2016 (Saturn).
