Space Radiation May Create Some Organic Molecules Detected on Icy Moons
Rethinking the Origins of Enceladus’s Organics For years, the plumes jetting from Saturn’s moon Enceladus have been a tantalizing clue in the search for habitability beyond Earth. The Cassini mission detected a suite of organic molecules in these icy geysers, suggesting a chemically rich environment beneath the frozen crust and a potential link to a…

Space Radiation May Create Some Organic Molecules Found in Enceladus Plumes
New insight into Enceladus’s chemistry Scientists are reconsidering how organic molecules detected in plumes erupting from Saturn’s icy moon Enceladus should be interpreted. A recent study proposes that some compounds previously thought to come from a subsurface ocean could instead be produced by natural radiation near the moon’s surface. While this doesn’t rule out a…

Space Radiation Could Create Organics on Enceladus and Other Icy Moons
Radiation Chemistry Isn’t Just for Earth: Implications for Enceladus For years, scientists have looked at the plumes erupting from Saturn’s icy moon Enceladus as a direct window into a hidden subsurface ocean. The idea was simple: material sampled in space could reveal the ocean’s chemistry, including potential building blocks of life. A growing body of…

New Molecules Found in Enceladus Water Jets Using Cassini Data
Breakthrough from Cassini’s Archive: Complex Organics in Enceladus’ Jets Enceladus, the icy moon orbiting Saturn, has long intrigued scientists with its geyser-like plumes. A new study drawing on archival data from NASA’s Cassini mission reveals a surprising abundance of complex organic molecules in the water-ice grains ejected from the moon’s south polar jets. This finding…

Does Saturn’s Moon Mimas Hide a Subsurface Ocean? A New Case for a Young Ocean
Introduction: A developing case for an ocean on Mimas Saturn’s small but storied moon Mimas may be harboring a subsurface ocean beneath a thick icy shell. Recent analyses, built on data from NASA’s Cassini mission and advanced modeling, suggest that the moon’s crust could be thin enough in certain regions to host liquid water not…

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 Organic Molecules Hint at Life Potential
Enceladus and the Search for Life’s Building Blocks Saturn’s icy moon Enceladus has long fascinated scientists with the possibility that it hosts a subsurface ocean. Even though NASA’s Cassini mission ended in 2017, researchers continue to squeeze new insights from its vast archive. The latest analyses bolster the case that Enceladus isn’t just a cold,…
