Summary:
- Researchers analyzing archival data from the Cassini spacecraft's Cosmic Dust Analyzer have identified five distinct chemical subtypes of salt-rich ice grains ejected from the plumes of Saturn's moon, Enceladus.
- The chemical composition of these grains suggests that Enceladus' subsurface ocean contains a complex environment with varying pH levels and diverse organic and inorganic compounds, further supporting the moon's potential habitability.
