Fermentation Heterotrophy Can Reproduce Enceladus’s H2 And CH4 Under Limited Serpentinization
[astro-ph.EP] Saturn’s icy moon Enceladus is a prime target in the search for life beyond Earth. Abundant H2 and CH4 in Enceladus’s south-polar plume have been shown to be consistent […]

Where Does Earth’s Nitrogen Go? Two Atoms Offer A Clue
[Science] Nitrogen is one of life’s building blocks, but it’s only helpful in the right amounts. Too much nitrogen in water, for example, can lead to poor water quality and […]

Paleo-heat Flux Estimates Across Enceladus Derived From Flexural Response Of The Ice Shell
[Icarus] Saturn’s moon Enceladus has active plumes suggestive of locally high heat fluxes at present, and the present-day heating is reasonably well characterized. However, the moon’s thermal history is not […]

Life On Saturn’s Moon Enceladus Would Be Possible
[University of Regensburg] From a human perspective, Enceladus is anything but a comfortable place to live: Icy cold, hardly any oxygen, and – below its icy crust – a global […]

How Enceladus’ Ocean Spray Becomes Chemically Diverse Ice Grains
[Institute of Science Tokyo] Saturn’s icy moon Enceladus hides a global ocean beneath its frozen surface. From fractures near its south pole, material from this ocean is ejected into space […]

The Enceladian Crater Production Function
[Icarus] Interpreting Enceladus’s past and present surface history and interior state remains challenging, owing to uncertain prescription of its impact bombardment history and limited interpretation of its crater statistics.

SwRI Simulations Indicate That Large Impacts May Limit Ocean Formation In Icy Moons
[SwRI] Southwest Research Institute (SwRI) scientists provided simulations to understand the role disruptive impacts play on icy moons with subsurface oceans in our solar system.
