How Does Ice Shell Geometry Shape Ocean Dynamics On Icy Moons?
A poleward-thinning ice shell can drive circulation in the subsurface oceans of icy moons by imposing a meridional temperature gradient–colder at the equator than the pole–through the freezing point suppression […]
Growth, Physiology, And Metabolism Of Halomonas Meridiana In Aqueous Ammonium Sulfate With Implications For Icy Moon Astrobiology
The discovery of extraterrestrial reservoirs of liquid water has motivated missions to icy moons Europa and Titan.
Unexpected Discovery On Titan Challenges Our View On Chemistry Before Life Emerged
Researchers at Chalmers University of Technology in Sweden and the US space agency NASA have made an unexpected discovery that challenges one of the basic rules of chemistry and provides […]
Enceladus’ Tidal Heating: A Simple Approach
Saturn’s moon Enceladus has a global ocean that is covered by an ice shell. The moon’s eccentric orbit forces the shell to librate, which distorts the shell and thereby generates […]
Special Issue of Geosciences: “Worlds of the Solar System: Geological Evolution and Habitability of Planets and Moons”
The Special Issue of Geosciences entitled “Worlds of the Solar System: Geological Evolution and Habitability of Planets and Moons” aims to bring together the latest advances on the dynamic processes […]
Using SOFIA’s EXES To Search For C6H2 And C4N2 in Titan’s Atmosphere
In Titan’s atmosphere, the chemistry of small hydrocarbons and nitriles represent an important link from molecular species to the ubiquitous organic haze that gives Titan its characteristic yellow color.
Zonal Winds In Titan’s Middle Atmosphere From A Stellar Occultation Observed With Keck Adaptive Optics
We present spatially resolved Keck/NIRC2 images of a stellar occultation by Titan on September 5, 2022 and compare them to predictions from concurrent ALMA observations and a suite of General […]
The Photochemical Plausibility of Warm Exo-Titans Orbiting M-Dwarf Stars
The James Webb Space Telescope (JWST) has begun to spectrally characterize small exoplanets orbiting M-dwarf stars, but interpretation of these spectra is ambiguous, with stellar, instrumental, or atmospheric origins possible […]
Modeling Low-Temperature Plasmas Simulating Titan’s Atmosphere
In the study presented here, we model the gas phase chemistry induced by plasma discharge at low temperature (150 K) in the NASA Ames COSmIC Simulation Chamber (COSmIC) using a […]
