The rings of Saturn are only a rainbow phenomenon: which is due to the light dispersion into its components, by passing through some ice or water particles in the atmosphere of Saturn.وَجَعَلْنَا مِنَ الْمَاء كُلَّ شَيْءٍ حَيٍّ أَفَلَا يُؤْمِنُونَ
It indicates that Saturn (and Neptune) has abundant water in its atmosphere, and so life does exist there on Saturn.
God - be exalted - said in the Quran 21: 30
The explanation:]
(And [We] made of water every living thing. So would they believe?)
