New Signatures of Bio-Molecular Complexity in the Hypervelocity Impact Ejecta of Icy Moon Analogues [PDF]
Life, 2022 Impact delivery of prebiotic compounds to the early Earth from an impacting comet is considered to be one of the possible ways by which prebiotic molecules arrived on the Earth.

Identifying signatures of past and present cryovolcanism on Europa [PDF]
Nature CommunicationsEuropa, the most visibly active icy moon of Jupiter, is a prime target for the search for life in the outer solar system. Two spacecraft missions, Europa Clipper from the National Aeronautics and Space Administration (NASA) and the Jupiter Icy Moon ...

Variations in plume activity reveal the dynamics of water-filled faults on Enceladus [PDF]
Nature CommunicationsAfter discovering a jet activity near the south pole of Saturn’s moon Enceladus, the Cassini mission demonstrated the existence of a subsurface water ocean with a unique sampling opportunity through flybys.

The 3D Direct Simulation Monte Carlo Study of Europa’s Gas Plume
Universe, 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
Geosciences, 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 ...

Prospects for Cryovolcanic Activity on Cold Ocean Planets
The Astrophysical Journal, 2023 We have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets that may be cold ocean planets, low-mass exoplanets with equilibrium surface temperatures and/or densities that are consistent with icy surfaces and a ...

JCPP Advances, Volume 2, Issue 4, December 2022., 2022 In this study, one–hundred and sixteen adolescents completed ecological momentary assessment (EMA) surveys assessing current positive and negative affect (PA and NA) and dimensions of spontaneous thought. Characteristics of spontaneous thought—including temporal orientation, self–referential quality, and task–relatedness—were differentially related to ...
