Ground-based detection of a cloud of methanol from Enceladus: When is a biomarker not a biomarker? [PDF]

, 2017
Saturn's moon Enceladus has vents emerging from a sub-surface ocean, offering unique probes into the liquid environment. These vents drain into the larger neutral torus in orbit around Saturn. We present a methanol (CH3OH) detection observed with IRAM 30-

Low effective ultraviolet exposure ages for organics at the surface of Enceladus

Communications Earth & Environment, 2023
The saturnian moon Enceladus presents a remarkable opportunity in our solar system for searching for evidence of life, given its habitable ocean and plume that deposits organic-bearing ocean material onto the surface.

Moonraker: Enceladus Multiple Flyby Mission

The Planetary Science Journal, 2022
Abstract Enceladus, an icy moon of Saturn, possesses an internal water ocean and jets expelling ocean material into space. Cassini investigations indicated that the subsurface ocean could be a habitable environment having a complex interaction with the rocky core.

The merger that led to the formation of the Milky Way's inner stellar halo and thick disk [PDF]

, 2018
The assembly process of our Galaxy can be retrieved using the motions and chemistry of individual stars. Chemo-dynamical studies of the nearby halo have long hinted at the presence of multiple components such as streams, clumps, duality and correlations ...

Librational response of Enceladus [PDF]

Geophysical Research Letters, 2010
Physical librations could significantly contribute to Enceladus' geophysics through their influence on tidal stress. Therefore it is important to determine their behavior and the present paper is devoted to estimating Enceladus' libration in longitude. In a rotational model of Enceladus with no global ocean, we introduce the main perturbative terms of ...

Surface ages of mid-size Saturnian satellites [PDF]

, 2015
The observations of the surfaces of the mid sized Saturnian satellites made by Cassini Huygens mission have shown a variety of features that allows study of the processes that took place and are taking place on those worlds.

Method for detecting and quantitating capture of organic molecules in hypervelocity impacts

MethodsX, 2021
Enceladus is a prime candidate in the solar system for in-depth astrobiological studies searching for habitability and life because it has a liquid water ocean with significant organic content and ongoing cryovolcanic activity. The presence of ice plumes
