Ocean Worlds Maintained by Ocean Tidal Heat Expected on Several Uranian Moons

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract In recent NASA decadal surveys, detecting oceans among Uranus' moons has been identified as a research priority in future missions. Currently, the prevailing view in planetary science is that the likelihood of finding oceans is highest on the larger moons, Titania and Oberon, due to their higher integrals of radiogenic heat sources.

Magnetic Flux Ropes at Mars and Their Impacts on Heavy Ion Escape

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Flux ropes (FRs), ubiquitous helical magnetic structures in solar system plasmas, are important to energy and particle transport. At Mars, where global intrinsic magnetic fields are absent, FRs form through magnetic reconnection (MR) and magnetospheric or ionospheric boundary wave instabilities (BWIs), but their role in ion escape remains ...

Saturn's Exploration Beyond Cassini-Huygens [PDF]

, 2009
For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar System and the evolution of giant planets in general.

The Rings of Saturn and Uranus [PDF]

Symposium - International Astronomical Union, 1979
Nature has presented us with two systems of planetary rings. They are not at all similar. Saturn has bright, broad rings separated by narrow gaps. The rings of Uranus are dark, narrow and widely spaced. Presumably both sets of rings lie inside the Roche limit and this is why the ring material has not condensed into satellites.

Ion Composition and Electron Pitch Angle Variations for Interchange Events in Jupiter's Inner Magnetosphere

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The outward transport of plasma and magnetic fluxes in the gas giant magnetospheres is balanced with a return flow of flux tubes emptied through magnetic reconnection. Evidence of interchange motions between inward and outward moving flux tubes have long been reported around Jupiter and Saturn.

From Anti‐Van't Hoff Le Bel Molecules of C6NH to Astronomically Relevant and Experimentally Known and Unknown Carbenes

ChemPhysChem, Volume 26, Issue 20, October 15, 2025.
Molecules with a planar tetracoordinate carbon atom serve as reactive intermediates for carbenes. While isomer 2 has been identified in the laboratory, isomer 5 remains elusive to date. Here, four stationary points with a planar tetracoordinate carbon (ptC) atom that are considered as anti‐van't Hoff Le Bel molecules have been computationally ...

A Specification Model of Saturn's Plasma Environment

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We present the first empirical‐based specification model of Saturn's plasma environment based on the analysis of all publicly available plasma moment data sets derived using multiple techniques from Cassini observations made by the Cassini Plasma Spectrometer and the Radio and Plasma Wave Science instrument.

Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e

The Astronomical Journal
Planets may be rotationally flattened, and their oblateness thus provides useful information on their formation and evolution. Here, we develop a new algorithm that can compute the transit light curve due to an oblate planet very efficiently and use it ...

Seismology of Giant Planets: General Overview and Results from the Kepler K2 Observations of Neptune

EPJ Web of Conferences, 2017
For this invited contribution, I was asked to give an overview about the application of helio and aster-oseismic techniques to study the interior of giant planets, and to specifically present the recent observations of Neptune by Kepler K2.

Saturn's Dusky Ring [PDF]

Nature, 1879
I WRITE to call the attention of observers to the present appearance of the inner dusky ring of Saturn. Although the ring is not very open, only permitting that portion near the ends to be seen on the nights of the 9th and 11th of this month, using a portion of a large reflector sufficient only to show Enceladus clearly, it was most prominent, and not ...
