The Cassini spacecraft found new complex organic molecules in fresh ice grains ejected from Saturn’s moon Enceladus.
It also, detected compounds include aliphatic, cyclic esters, ethers, and possible nitrogen- and oxygen-bearing molecules.
These molecules originate from Enceladus’s subsurface ocean, not from long-term radiation exposure in Saturn’s E ring.
The findings confirm active complex chemistry in Enceladus’s ocean, strengthening the case for a future ESA (European Space Agency) mission to the moon.
