THE RESULTS OF OBSERVATIONS OF MUTUAL PHENOMENA OF THE GALILEAN SATELLITES OF JUPITER IN 2009 AND 2015 IN NIKOLAEV ASTRONOMICAL OBSERVATORY

Odessa Astronomical Publications, 2016
The Earth and Jupiter once in 6 years have simultaneous passage of the ecliptic plane due to their orbital movement around the Sun. This makes it possible to observe the mutual occultations and eclipses in the Galilean satellites of Jupiter. We took part

Electron impact ionization in the icy Galilean satellites’ atmospheres

, 2023
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 (

Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.

Eclipses and Occultations of Galilean Satellites Observed at Yunnan Observatory in 2003

, 2007
We describe and analyze observations of mutual events of Galilean satellites made at the Yunnan Observatory in February 2003 from CCD imaging for the first time in China. Astrometric positions were deduced from these photometric observations by modelling

Discrete Energy Bands Beyond Galilean Moons: Bounce‐Phase Structuring of Jovian Magnetospheric Particles

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Discrete energy bands of ion fluxes, typically organized in velocity with equal separations, have been frequently observed in Jupiter's magnetosphere either in association with Galilean moons or in regions far from their influence. Here, we focus on the latter type and propose that these bands are manifestations of bounce‐phase structuring ...

Europa’s Sodium and Potassium Exosphere during Juno’s Flyby

The Planetary Science Journal
Jupiter’s icy moon Europa is enveloped in gaseous sodium and potassium that resonantly scatter sunlight as optical emission lines. The High Resolution Echelle Spectrograph on the Keck I telescope has spatially mapped these alkalis contemporaneously with ...

Ice chemistry on the Galilean satellites [PDF]

Journal of Geophysical Research: Planets, 1998
Jupiter's icy satellites Europa, Ganymede, and Callisto are subject to energy fluxes from electrons, photons, and magnetospheric plasma ion bombardment. As water ice and CO2 ice are thought to be present on their surfaces, the radiolysis of these materials over time should produce more complicated CHO‐containing molecules. These may include CH3OH, H2CO,

Unobservable mutual events of the Galilean satellites

, 2002
Mutual eclipses and occultations of the Galilean satellites of Jupiter which will occur in 2002–2003 were predicted independently by J.-E. Arlot and by K.

Longitudinal Tracking of Astrocyte Reactivity During the Development of Chronic Orofacial Neuropathic Pain Using [18F]‐SMBT‐1 Positron‐Emission Tomography

Glia, Volume 74, Issue 8, August 2026.
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 ...

Lava Lakes on Io: Crust Age and Implications for Thermal Output

The Planetary Science Journal
Recent observations by the JIRAM instrument on board NASA’s Juno spacecraft have confirmed that many of Io’s volcanic hotspots are active lava lakes, characterized by a colder central crust surrounded by a hotter peripheral ring.
