Probing Ganymede’s Atmosphere with HST Lyα Images in Transit of Jupiter

The Planetary Science Journal, 2023
We report results from far-ultraviolet observations by the Hubble Space Telescope of Jupiter’s largest moon, Ganymede, transiting across the planet’s dayside hemisphere.

Theory of Motion of Jupiter’s Galilean Satellites [PDF]

International Astronomical Union Colloquium, 1978
AbstractThe final results for the theory enabling one to calculate the positions of the Galilean satellites and their partial derivatives are presented, following the techniques outlined in earlier papers. Extensive use of algebraic manipulation software on a digital computer is employed to generate the final expressions.

Galilean Satellites and the Galileo Space Mission [PDF]

International Astronomical Union Colloquium, 1997
AbstractThe Galileo spacecraft arrived at Jupiter in December 1995 to start its two-year mission of exploring the Jovian system. The spacecraft will complete eleven orbits around Jupiter and have ten more close encounters with the outer three Galilean satellites, after the initial close approach to Io on December 7, 1995.

Detecting Exomoons from Radial Velocity Measurements of Self-luminous Planets: Application to Observations of HR 7672 B and Future Prospects

The Astronomical Journal, 2023
The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these elusive objects from radial velocity monitoring of self-luminous, directly imaged ...

Mass-wasting Features on Galilean Icy Moons: Morphological Analysis and Implications

The Planetary Science Journal
This study investigates mass-wasting features on the icy Galilean satellites Europa, Ganymede, and Callisto. Through comparative morphological analysis, we identified and classified slides, slumps, and flow-like deposits as mass-wasting categories using ...

Io’s Optical Aurorae in Jupiter’s Shadow

The Planetary Science Journal, 2023
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

Meteoritics &Planetary Science, EarlyView.
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 Planetary Science Journal
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 ...

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior. We present an updated interior structure for Callisto derived from a reanalysis of Galileo's Doppler tracking data using new signal processing techniques.

Surface Deposition of Icy Dust Entrained in Europa’s Plumes

The Planetary Science Journal
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.
