Ceres’ Broad‐Scale Surface Geomorphology Largely Due To Asymmetric Internal Convection
AGU Advances, 2022 While we now know much about the volatile‐rich world of Ceres from the Dawn mission, the deep interior remains something of an enigma, shrouded by a crust composed of water ice, carbonates, phyllosilicates, salts and clathrate hydrates.

The archaeal class Halobacteria and astrobiology: Knowledge gaps and research opportunities
Frontiers in Microbiology, 2022 Water bodies on Mars and the icy moons of the outer solar system are now recognized as likely being associated with high levels of salt. Therefore, the study of high salinity environments and their inhabitants has become increasingly relevant for ...

Energetic Constraints on Ocean Circulations of Icy Ocean Worlds
The Planetary Science Journal, 2023 Globally ice-covered oceans have been found on multiple moons in the solar system and may also have been a feature of Earth’s past. However, relatively little is understood about the dynamics of these ice-covered oceans, which affect not only the ...

Large planets may not form fractionally large moons [PDF]
Nature Communications 13, 568 (2022), 2023 One of the unique aspects of Earth is that it has a fractionally large Moon, which is thought to have formed from a Moon-forming disk generated by a giant impact. The Moon stabilizes the Earth's spin axis at least by several degrees and contributes to Earth's stable climate.

A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons
The Astrophysical Journal, 2023 We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn’s remarkably young rings. Such an event could have been triggered a few hundred million years ago by resonant instabilities in a previous ...

New Signatures of Bio-Molecular Complexity in the Hypervelocity Impact Ejecta of Icy Moon Analogues
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.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Data acquisition in planetary remote sensing missions is influenced by complex environmental resource- and instrument-specific constraints. This impedes to perform observations at any given time during the mission and with any of the instruments ...

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 ...

The Planetary Science Journal, 2023 Some icy moons and small bodies in the solar system are believed to host subsurface liquid water oceans. The interaction of these saline, electrically conductive oceans with time-varying external magnetic fields generates induced magnetic fields ...
