Enough Sulfur and Iron for Potential Life Make Enceladus’s Ocean Fully Habitable

The Astrophysical Journal Letters
The Cassini spacecraft revealed life-forming elements like CHNOP and diverse organic compounds from Enceladus’s ocean. However, the availability of minor but bio-essential nutrients such as iron and sulfur remains unknown.

The two faces of Gaia-Sausage-Enceladus

Astronomy & Astrophysics
Aims. Recent studies suggest that chemical abundances hold the key to disentangling halo substructures, providing a more reliable tracer than dynamics alone. We aim to probe the Milky Way stellar halo using high-dimensional chemical abundances from GALAH

An upper limit on Enceladus’ obliquity [PDF]

, 2014
Control point calculations using Cassini images reveal that Enceladus’ obliquity is limited to less than 0.05° (95% confidence level). This definitely rules out models explaining Enceladus’ activity and anomalously high surface heat flows on the basis of

Nonlinear Wave–Wave Interactions of Ion Cyclotron Waves in Saturn’s Magnetosphere: Cassini Observations and Theoretical Predictions

The Astrophysical Journal
Ion cyclotron waves (ICWs) are commonly observed in Saturn’s inner magnetosphere, especially near Enceladus. Quasi-parallel ICWs are often thought to be excited by temperature-anisotropic ions, and these waves can drive nonlinear interactions when their ...

Raman Spectroscopy of Salt Deposits from the Simulated Subsurface Ocean of Enceladus

The Planetary Science Journal
Enceladus may host a subsurface ocean with biologically relevant chemistry. Plumes released from this ocean preserve information on its chemical state, and previous analyses suggest weakly to strongly alkaline pH.

Habitability of Enceladus: Planetary Conditions for Life

, 2008
The prolific activity and presence of a plume on Saturn's tiny moon Enceladus offers us a unique opportunity to sample the interior composition of an icy satellite, and to look for interesting chemistry and possible signs of life. Based on studies of the

The ERP (Enceladus Research Probe) Mission

The ERP mission proposes an expedition to search for evidence of life on Enceladus, one of Saturn’s many moons. The goal of this project is to send a lander and an ice and water probe to Enceladus to analyze the thick icy crust for organic compounds as ...

Improving Porosity Calculation Methods and Proposing a New Model Universally Applicable to Large- and Medium-sized Planetary Objects

The Astrophysical Journal
Our work was aimed at the improvement of two main already existing methods of porosity calculation on a planetary scale in order to expand these methods to be applicable to exoplanetary interiors. In addition to implementing some improvements in the used
