This paper reviews the recent findings of the Herschel Solar System Observations Key Program (Hartogh et al. 2009b), as well as ground-based supporting observations, regarding the origin of external oxygen in the environments of Jupiter and Saturn. Herschel-HIFI and PACS observations have been used to shown that the Shoemaker-Levy 9 comet is the source of Jupiter’s stratospheric water, and that Enceladus (and its geysers) are most probably the source of water for Saturn and Titan.
