Study finds Enceladus's plumes naturally concentrate ocean material into ice grains
Researchers led by Frank Postberg found that as ocean droplets from Enceladus shoot through icy cracks at speeds up to 1,000 km/h, they shatter into micrometer-sized ice particles that often contain a single, concentrated substance from the moon's subsurface ocean. This natural separation process mimics chemical lab preparation, isolating individual oceanic components into distinct ice grains before they are ejected into space.
