Thermal Segregation and Reddening in Europa's Double Ridges

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
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 ...

Mapping of the Ganymede surface reflectance from Juno/UVS data

Astronomy & Astrophysics
Context. Ganymede is the only moon in the Solar System with an intrinsic magnetic field that actively interacts with the Jupiter magnetosphere. This precipitates energetic electrons that generate ultraviolet (UV) auroral emission. Aims. In sunlit auroral

Shallow Impact Craters Suggest Titan Stores Methane in an Insulating Clathrate Crust

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Multiple lines of evidence suggest that a methane‐clathrate crustal layer exists in Titan. However, we have not directly confirmed the existence or thickness of this hypothesized layer, a potentially important methane reservoir. Here, we model impact crater formation and subsequent viscoelastic evolution in Titan's ice shell with methane ...

Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

UVS Observations of Ganymede's Aurora During Juno Orbits 34 and 35

Geophysical Research Letters, 2022
On 7 June 2021, Juno‐UVS mapped Ganymede's auroral emissions near a closest approach altitude of 1,046 km. The high spatial resolution map exhibits bright, 200–1,000 R, oxygen emissions organized into northern and southern auroral ovals.

The Earth transiting the Sun as seen from Jupiter's moons: detection of an inverse Rossiter-McLaughlin effect produced by the Opposition Surge of the icy Europa [PDF]

, 2015
We report on a multi-wavelength observational campaign which followed the Earth's transit on the Sun as seen from Jupiter on 5 Jan the 2014. Simultaneous observations of Jupiter's moons Europa and Ganymede obtained with HARPS from La Silla, Chile, and ...

Ganymede’s Tenuous Atmosphere

Ganymede possesses a tenuous water-based atmosphere, thought to be produced by the solar and Jovian plasma irradiation of its icy surface. Observational evidence for Ganymede's atmosphere is provided by far-ultraviolet (FUV) emission from the atomic oxygen (O) and hydrogen (H) constituents.

New Results From Galileo's First Flyby of Ganymede: Reconnection‐Driven Flows at the Low‐Latitude Magnetopause Boundary, Crossing the Cusp, and Icy Ionospheric Escape

Geophysical Research Letters, 2018
On 27 June 1996, the NASA Galileo spacecraft made humanity's first flyby of Jupiter's largest moon, Ganymede, discovering that it is the only moon known to possess an internally generated magnetic field. Resurrecting the original Galileo Plasma Subsystem

Why Ganymede Faints and the Duke of York Weeps: Passion Plays in Shakespeare [PDF]

, 2017
This article revisits contemporary critical debates surrounding the presence of cross-dressed boys as women on the early modern stage – in particular the question of whether or to what extent boy-actors could or should be said to represent ‘women’ or ...
