Exploring the Habitability of the Outer Solar System Icy Moons for the Extremotolerant Yeast Rhodotorula frigidalcoholis. [PDF]

Environ Microbiol
We investigated the survival of the yeast Rhodotorula frigidalcoholis and analysed its RNA after exposure to icy moon conditions. Our results show how the yeast can tolerate the extreme conditions and performs metabolic functions under the exposure conditions; for example, by halting the cell cycle in order to repair. Created in BioRender.

Microwave Observations of Ganymede's Sub‐Surface Ice: I. Ice Temperature and Structure

Journal of Geophysical Research: Planets, 2023
On 7 June 2021, Juno flew within 1,000 km of Ganymede's surface, partially mapping its ice shell at six frequencies ranging from 0.6 to 22 GHz. The radiance at these frequencies originates from successively deeper layers of the sub‐surface and may reach ...

On the Representation of Ganymede in the Roman Mosaic of the Loves of Zeus from Astigi (Baetica)

Journal of Mosaic Research, 2020
The discovery in 2015 of the great mosaic so called of the Zeus’ Loves in Écija (Sevilla) comes to highlight again the quality of the mosaic heritage of the ancient Astigi, capital of the conventus astigitanus in Baetica.

Structural geology of Ganymede regional groove systems (60°N–60°S)

Journal of Maps, 2020
Brittle deformation on Ganymede surface is represented by grooves tectonic linear landforms. These are regional scale structures that show well-defined morphology from straight to curvilinear. High density of grooves occupies most of the light terrain of

Characterization of carbon dioxide on Ganymede and Europa supported by experiments: Effects of temperature, porosity, and mixing with water [PDF]

Astronomy & Astrophysics
The surfaces of icy moons are primarily composed of water ice that can be mixed with other compounds, such as carbon dioxide. The carbon dioxide (CO$_2)$ stretching fundamental band observed on Europa and Ganymede appears to be a combination of several ...

A Model of Ganymede's Magnetic and Plasma Environment During the Juno PJ34 Flyby

Journal of Geophysical Research: Space Physics, 2023
Using a hybrid model (kinetic ions, fluid electrons), we provide context for plasma and magnetic field observations from Juno's PJ34 flyby of Ganymede on 07 June 2021.

The NIR transmission spectrum of Jupiter from the observation of a Ganymede’s eclipse

EPJ Web of Conferences, 2015
Here, we report the NIR transmission spectrum of Jupiter, with high signal-to-noise ratio, as if it were a transiting planet. Our technique was to observe Ganymede, when crossing Jupiter’s shadow.

Global Modeling of Ganymede's Surface Composition: Near‐IR Mapping From VLT/SPHERE [PDF]

Journal of Geophysical Research: Planets, 2022
We present maps of Ganymede's surface composition with almost complete longitude coverage, acquired using high spatial resolution near‐infrared (0.95–1.65 μm) observations from the ground‐based VLT/SPHERE instrument.

Early Stages of Galilean Moon Formation in a Water-depleted Environment

The Astrophysical Journal Letters, 2023
A key feature of the Galilean satellite system is its monotonic decrease in bulk density with growing distance from Jupiter, indicating an ice mass fraction that is zero in the innermost moon Io and about half in the outer moons Ganymede and Callisto ...

The generation of Ganymede's diffuse aurora through pitch angle scattering [PDF]

Annales Geophysicae, 2017
Diffuse auroral intensities of neutral atomic oxygen OI λ1356 Å emission on Ganymede due to whistler mode waves are estimated. Pitch angle diffusion of magnetospheric electrons into the loss cone due to resonant wave–particle interaction of whistler ...
