Mimas Ocean: Evidence for a Subsurface Sea in Saturn’s Moon
The Case for a Newborn Ocean on Mimas The idea that Saturn’s moon Mimas might host a subsurface ocean has moved from speculation to a serious scientific hypothesis. Researchers analyzing Cassini data and applying models of ice-shell behavior found that Mimas could possess an ocean buried under 12 to 19 miles (20–30 kilometers) of solid…

JWST Study of CO2 on Saturn’s Satellites Reveals Varieties
Introduction The James Webb Space Telescope (JWST) is pushing the frontiers of planetary science by analyzing the composition of bodies far from Earth. A new study using JWST spectra investigates carbon dioxide (CO2) on eight mid-sized Saturnian satellites, from the inner moons Mimas, Enceladus, Tethys, Dione, and Rhea to the outer ones Hyperion, Iapetus, and…

Enceladus Organics Hint at Possible Life on Saturn’s Moon
A Hidden Ocean and Organic Clues The icy moon Enceladus keeps revealing surprises about its watery interior. Although the Cassini mission ended in 2017, scientists are still mining its archived data for hidden clues. In 2005, Cassini detected plumes of water vapor shooting from fractures near Enceladus’ south polar region. The prevailing interpretation is that…
