Late‐Stage Debris Flows Eroded Aeolis Mons in Gediz Vallis, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract How the ancient climate of Mars transitioned to its current cold, hyperarid state is recorded by the sedimentary rocks preserved on its surface. Gale crater, the Curiosity rover landing site, is one such location, where the central mountain, Aeolis Mons, preserves an extensive sedimentary record. Curiosity has demonstrated that the Aeolis Mons

The Ultraviolet Slopes of Early Universe Galaxies: The Impact of Bursty Star Formation, Dust, and Nebular Continuum Emission

The Astrophysical Journal
JWST has enabled the detection of the ultraviolet (UV) continuum of galaxies at z > 10, revealing extremely blue, potentially dust-free galaxies. However, interpreting UV spectra is complicated by the well-known degeneracy between stellar ages, dust ...

Effect of Unstable Water Flow on Grain Transport: Insights From Laboratory Experiments Under Reduced Atmospheric Pressure

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Nowadays, Mars presents an environment characterized by low atmospheric pressure (∼6 mbar), which profoundly alters water‐driven surface processes known from Earth. Under these conditions, water rapidly boils, cools, and stabilizes near the triple point, often freezing, which strongly limits its ability to transport sediment.

Characterization of Dust in Saturn's Rings Using Cassini Spacecraft Data

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The dust distribution in Saturn's rings is investigated using dust impacts registered by the Radio and Plasma Wave Science (RPWS) instrument onboard the Cassini spacecraft. Dust impacts, recorded as spiky signals in electric field waveforms, are used to determine profiles of impact rates and amplitudes of spikes during individual equatorial ...

Shoulder of Dust Rings Formed by Planet–Disk Interactions

The Astrophysical Journal
Recent analyses of millimeter-wavelength protoplanetary disk observations have revealed several emission excesses on the previously identified dust rings, referred to as dust shoulders.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Exploring Potential Mechanisms for the Initiation of Solifluction Patterns

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Hillslopes in arctic regions commonly display large‐scale features—known as solifluction patterns—that form due to the exceedingly slow downhill movement of frost‐heaved soil. Here we use a combination of remote sensing data, linear stability analysis, numerical modeling, and review of a wide range of literature to evaluate several working ...

Reconstructing the Exhumation and Paleo‐Earthquake History of a Submarine Normal Fault From Preserved Markers at the Seafloor (Roseau Fault, Lesser Antilles, France)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Assessing seismic and tsunami hazards along coastlines requires understanding past earthquakes and their recurrence along active submarine faults. Subaqueous paleoseismology commonly relies on sediment cores and seismic reflection data, but these methods may be limited by local site conditions or data quality.

Distances to Recent Near-Earth Supernovae from Geological and Lunar 60Fe

The Astrophysical Journal
Near-Earth supernova blasts which engulf the solar system have left traces of their ejecta in the geological and lunar records. There is now a wealth of data on live radioactive ^60 Fe pointing to a supernova at 3 Myr ago, as well as the recent discovery
