Tidal Seismicity in the Moon and Implications for the Rocky Interior of Europa

open access: yesThe Planetary Science Journal
Seismology is a powerful tool for probing the deep interiors of planetary bodies. Just as deep moonquakes triggered by Earth’s tides occur on the Moon, as observed by the Apollo seismometers, icy moons of the giant planets may also have seismically ...

The 3D Direct Simulation Monte Carlo Study of Europa’s Gas Plume

open access: yesUniverse, 2022
Europa has been spotted as having water outgassing activities by space- and ground-based telescopes as well as reanalysis of the Galileo data. We adopt a 3D Direct Simulation Monte Carlo (DSMC) model to investigate the observed plume characteristics of ...

A Geoscientific Review on CO and CO2 Ices in the Outer Solar System

open access: yesGeosciences, 2022
Ground-based telescopes and space exploration have provided outstanding observations of the complexity of icy planetary surfaces. This work presents our review of the varying nature of carbon dioxide (CO2) and carbon monoxide (CO) ices from the cold ...

Large planets may not form fractionally large moons

open access: yesNature Communications, 2022
This study finds that the Moon accreted from an initially liquid-rich silicate disk and that rocky and icy exoplanets whose radii are smaller than 1.6 Earth radii are ideal candidates for hosting large exomoons.

Juno's Close Encounter With Ganymede—An Overview

open access: yesGeophysical Research Letters, 2022
The Juno spacecraft has been in orbit around Jupiter since 2016. Two flybys of Ganymede were executed in 2021, opportunities realized by evolution of Juno's polar orbit over the intervening 5 years.

How to Detect Life on Icy Moons [PDF]

open access: yesAstrobiology, 2018
The icy moons of the outer Solar System present the possibility of subsurface water, habitable conditions, and potential abodes for life. Access to evidence that reveals the presence of life on the icy moons can be facilitated by plumes that eject material from the subsurface out into space.

Introduction to Dione’s Wispy Terrain as a Putative Model Region for “Micro” Wilson Cycles on Icy Satellites

open access: yesRemote Sensing, 2023
The Wispy Terrain is the region of chasmata characterized by quasi-parallel fault systems, formed by extensional and shear stresses of the icy crust of Dione, a moon of Saturn.
