  author={Frank Postberg and J Schmidt and John K. Hillier and Sascha Kempf and Ralf Srama},
The discovery of a plume of water vapour and ice particles emerging from warm fractures (‘tiger stripes’) in Saturn's small, icy moon Enceladus raised the question of whether the plume emerges from a subsurface liquid source or from the decomposition of ice. Previous compositional analyses of particles injected by the plume into Saturn's diffuse E ring have already indicated the presence of liquid water, but the mechanisms driving the plume emission are still debated. Here we report an analysis… 
Ongoing hydrothermal activities within Enceladus
Analysis of silicon-rich, nanometre-sized dust particles (so-called stream particles) that stand out from the water-ice-dominated objects characteristic of Saturn indicate ongoing high-temperature (>90 °C) hydrothermal reactions associated with global-scale geothermal activity that quickly transports hydroThermal products from the ocean floor at a depth of at least 40 kilometres up to the plume of Enceladus.
Cassini finds molecular hydrogen in the Enceladus plume: Evidence for hydrothermal processes
The Ion Neutral Mass Spectrometer onboard the Cassini spacecraft is used to detect molecular hydrogen in the plume of escaping material on Enceladus, finding that the most plausible source of this hydrogen is ongoing hydrothermal reactions of rock containing reduced minerals and organic materials.
Possible evidence for a methane source in Enceladus' ocean
The internal ocean of Enceladus can be expected to present conditions favorable to the trapping of volatiles in clathrates. This process could influence the eventual composition of the ocean and
Enceladus: Evidence and Unsolved Questions for an Ice-Covered Habitable World
The icy midsized satellite of Saturn—Enceladus—has become the central to astrobiology since the finding of its dramatic ongoing geological activity. The water-rich plumes erupting from the warm
The Carbonate Geochemistry of Enceladus' Ocean
The plume composition at Enceladus contains clues about conditions and processes in the interior. We present new geochemical interpretations of Cassini mass spectrometry data from the plume gas and
Timing of water plume eruptions on Enceladus explained by interior viscosity structure
Water plume eruptions on Saturn’s icy moon Enceladus are delayed relative to the peak tidal stresses. Simulations suggest the delay can be explained by the moon’s interior structure and the presence
An observed correlation between plume activity and tidal stresses on Enceladus
It is reported that the plume’s horizontally integrated brightness is several times greater when Enceladus is near the point in its eccentric orbit where it is furthest from Saturn than it is when close to the point of closest approach to the planet.
Strength Evolution of Ice Plume Deposit Analogs of Enceladus and Europa
Enceladus and possibly Europa spew materials from their internal ocean into their exosphere, some of which are deposited back onto the surface of those Ocean Worlds. This setting provides a unique
Fresh emplacement of hydrated sodium chloride on Ceres from ascending salty fluids
The surface and internal structure of Ceres show evidence of a global process of aqueous alteration, indicating the existence of an ocean in the past. However, it is not clear whether part of this


Sodium salts in E-ring ice grains from an ocean below the surface of Enceladus
The identification of a population of E-ring grains that are rich in sodium salts, which can arise only if the plumes originate from liquid water, and the abundance of various salt components in these particles exhibit a compelling similarity to the predicted composition of a subsurface Enceladus ocean in contact with its rock core.
Liquid water on Enceladus from observations of ammonia and 40Ar in the plume
Jets of water ice from surface fractures near the south pole of Saturn’s icy moon Enceladus produce a plume of gas and particles. The source of the jets may be a liquid water region under the ice
No sodium in the vapour plumes of Enceladus
A ground-based spectroscopic search for atomic sodium near Enceladus places an upper limit on the mixing ratio in the vapour plumes orders of magnitude below the expected ocean salinity.
Is Enceladus' plume tidally controlled?
Explanations for the plume of gas, water vapor and ice particles jetting from rifts in Enceladus' south polar region include boiling of liquid water and dissociation of clathrate hydrates. In either
Slow dust in Enceladus' plume from condensation and wall collisions in tiger stripe fractures
It is shown that repeated wall collisions of grains, with re-acceleration by the gas, induce an effective friction, offering a natural explanation for the reduced grain velocity, and suggests liquid water below Enceladus’ south pole.
Shear heating as the origin of the plumes and heat flux on Enceladus
It is shown that the most likely explanation for the heat and vapour production is shear heating by tidally driven lateral (strike-slip) fault motion with displacement of ∼0.5 m over a tidal period, suggesting that the ice shell is decoupled from the silicate interior by a subsurface ocean.
An oceanic composition on early and today's Enceladus
The oceanic composition on Saturn's moon Enceladus is evaluated through calculations of thermochemical equilibria at hydrothermal and freezing settings. Conditions of rock alteration are constrained
A Clathrate Reservoir Hypothesis for Enceladus' South Polar Plume
We hypothesize that active tectonic processes in the south polar terrain of Enceladus, the 500-kilometer-diameter moon of Saturn, are creating fractures that cause degassing of a clathrate reservoir
The composition and structure of the Enceladus plume
The Cassini Ultraviolet Imaging Spectrograph (UVIS) observed an occultation of the Sun by the water vapor plume at the south polar region of Saturn's moon Enceladus. The Extreme Ultraviolet (EUV)
