A Constraint on the Density of Jupiter’s Moon Thebe from Primordial Dynamics

The Astrophysical Journal Letters
Of the 97 known satellites in the Jovian system, the individual masses and densities of each moon have only been determined for six of them: the four Galileans, Amalthea, and Himalia. In this Letter, we derive a prediction for the mean density (and mass)

The thermal/ sensory gravity “S.O.S.” the last phase (40°–50° C) of global warming [PDF]

INCAS Bulletin
The gravitational buckling is an ice hole or black hole in the frozen quantum binary space penetrated by the light ignition, the backscattering of radiant thermal energy, where the quantum light barrier (cs = 1010 m/s) breaks together with the thermal ...

Transport of Water in a Transient, Impact‐Generated Atmosphere on Mercury

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mercury's polar cold traps host water ice deposits that are likely populated with impact‐delivered water via Mercury's exosphere. However, Mercury's near‐sun location experiences an extremely high photodestruction rate that rapidly destroys water with a timescale of only ∼3.5 hr.

Comparing NASA Discovery and New Frontiers Class Mission Concepts for the Io Volcano Observer

The Planetary Science Journal
Jupiter’s moon Io is a highly compelling target for future exploration that offers critical insight into tidal dissipation processes and the geology of high heat flux worlds, including primitive planetary bodies, such as the early Earth, that are shaped ...

Exploring Enceladus's Interior Structure Using Electromagnetic Induction

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its hydrothermally active core. Here, we assess the feasibility of EM sounding at Enceladus using both global (orbiter) and local (lander) EM induction transfer ...

NGTS-5b: a highly inflated planet offering insights into the sub-Jovian desert [PDF]

, 2019
Context: Planetary population analysis gives us insight into formation and evolution processes. For short-period planets, the subJovian desert has been discussed in recent years with regard to the planet population in the mass/period and radius/period ...

Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Juno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of‐flight data into contributions from individual ion species using species‐dependent fits. At the

Magnetic signatures of plasma-depleted flux tubes in the Saturnian inner magnetosphere

, 2007
Initial Cassini observations have revealed evidence for interchanging magnetic flux tubes in the inner Saturnian magnetosphere. Some of the reported flux tubes differ remarkably by their magnetic signatures, having a depressed or enhanced magnetic ...

Near-infrared Brightness of the Galilean Satellites Eclipsed in Jovian Shadow: A New Technique to Investigate Jovian Upper Atmosphere [PDF]

, 2014
Based on observations from the Hubble Space Telescope and the Subaru Telescope, we have discovered that Europa, Ganymede, and Callisto are bright around 1.5 μm even when not directly lit by sunlight.

Global Effects of Chorus and Hiss Waves on Trapped Energetic Electrons at Jupiter

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Unlike Earth, where whistler‐mode chorus is generally observed outside the plasmasphere and hiss is predominantly confined within it, Jupiter's magnetosphere frequently hosts both wave modes simultaneously. Using Juno observations, we present a global survey of whistler‐mode waves at Jupiter, demonstrating that both chorus and hiss are ...
