Where the Mineral Kingdom Might Hide New Forms of Matter

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Mineralogy has traditionally classified matter primarily through local chemistry and diffraction symmetry. But some physically distinct states of matter differ neither principally in composition nor in obvious diffraction symmetry; they differ in how fluctuations behave over very large distances.

Empirical Parameterizations of ULF Power and Drift Orbit Averaged Radial Diffusion Coefficients From Ground Magnetometers for Different MLT

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.

Seismic Oscillations Excited by Giant Impacts in Directly Imaged Giant Planets

The Astrophysical Journal
The radii and masses of many giant exoplanets imply their interiors each contain more than ∼100 M _⊕ of solids. A large metal content may arise when a giant planet grows by colliding and merging with multiple ∼10 M _⊕ solid cores.

PROSWIN: Probabilistic Solar Wind Speed Forecasting Using Deep Distributional Regression From Solar Images

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.

Empirically Constraining the Spectra of Stellar Surface Features Using Time-resolved Spectroscopy

The Astrophysical Journal Letters
Transmission spectroscopy is currently the technique best suited to study a wide range of planetary atmospheres, leveraging the filtering of a star’s light by a planet’s atmosphere rather than its own emission.

The Spatial Localization of Storm‐Time ULF Waves Due To Plasmaspheric Plumes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The generation and propagation of Ultra Low Frequency (ULF) waves are intrinsically coupled to the cold plasma population in the terrestrial magnetosphere. During geomagnetic storms, extreme reconfigurations of the cold plasma create a complex and dynamic system that drastically modifies this coupling.

An Evolving Cosmic Shoreline and Sandbar Bounding the Rocky Airless Valley

The Astrophysical Journal Letters
Recent JWST observations challenge the traditional “cosmic shoreline” from both sides, revealing thick volatile atmospheres on the hottest close-in “lava worlds,” where irradiation should drive the most extreme escape, and bare rocky surfaces on cooler ...

Venus as an Anchor Point for Planetary Habitability [PDF]

A major focus of the planetary science and astrobiology community is the understanding of planetary habitability, including the myriad factors that control the evolution and sustainability of temperate surface environments such as that of Earth.

Suprathermal Electron Acceleration Comparison of the Venusian and Terrestrial Bow Shocks

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract We study suprathermal electron acceleration at the Venusian bow shock using the Parker Solar Probe gravity assists and the Venus Express spacecraft mission. The acceleration is classified by measuring the maximum energy and the power‐law spectral slope (index) of the electron phase space density immediately downstream of the shocks for ...
