Io’s Optical Aurorae in Jupiter’s Shadow
Decline and recovery timescales surrounding eclipse are indicative of the controlling physical processes in Io’s atmosphere. Recent studies have established that the majority of Io’s molecular atmosphere, SO _2 and SO, condenses during its passage ...

Morpho‐structural analysis of impact craters on Pluto: Implications for the study of complex craters
Abstract We used Pluto's global digital elevation model to automatically perform a morphometric analysis of impact craters. Triangular irregular networks (TINs) were generated for each crater, providing a detailed representation of crater topography and enabling more accurate morpho‐structural analysis. A dedicated toolkit generated radial profiles for

Length, Width, and Relative Age Analysis of Lineaments in the Galileo Regional Maps with LineaMapper
The Galileo regional mosaics (“RegMaps”) show Europa’s extensive regional-scale tectonic features under similar illumination conditions. Detailed lineament studies can help constrain resurfacing events and formation mechanisms, but most lineament maps ...

ABSTRACT Determinism is (roughly) the thesis that the past determines the future. But efforts to define it precisely have exposed deep methodological disagreements. Standard possible‐worlds formulations of determinism presuppose an “agreement” relation between worlds, but this relation can be understood in multiple ways, none of which is particularly ...

Electron impact ionization in the icy Galilean satellites’ atmospheres
Electron impact ionization is critical in producing the ionospheres on many planetary bodies and, as discussed here, is critical for interpreting spacecraft and telescopic observations of the tenuous atmospheres of the icy Galilean satellites of Jupiter (

Surface Deposition of Icy Dust Entrained in Europa’s Plumes
Europa, an icy moon of Jupiter, features complex surface characteristics shaped by tidal forces and interactions with its subsurface ocean, making it a key target for astrobiology research.

The Optical Aurorae of Europa, Ganymede, and Callisto
The tenuous atmospheres of the Galilean satellites are sourced from their surfaces and produced by a combination of plasma-surface interactions and thermal processes. Even though they are thin, these atmospheres can be studied via their auroral emissions,

Using [18F]‐SMBT‐1 PET, we longitudinally tracked MAO‐B–expressing reactive astrocytes during orofacial neuropathic pain development in rats, revealing region‐ and time‐specific astrocyte activation during pain chronification. ABSTRACT Chronic neuropathic pain represents a significant global health burden and is hypothesized to be maintained by an ...

Crater Morphometry on Callisto
Impact crater formation is affected by the physical properties of planetary crusts, allowing comparison of crater dimensions to serve as a proxy for comparing the crustal properties of different planetary bodies.

Thermal Segregation and Reddening in Europa's Double Ridges
Abstract Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation‐driven darkening due to illumination and self‐heating—the process of thermal segregation. We apply an advanced 3D thermophysical model, including shadowing and self‐heating through mutual exchange of ...
