Widespread Impact‐Induced Crustal Permeability on the Early Earth
AGU Advances, Volume 7, Issue 3, June 2026.Abstract The early Earth (i.e., Archean and Hadean Eons, 2.5–4.0 and 4.0–4.5 Ga, respectively) experienced frequent cosmic bombardment. Impacts have been shown to stimulate crustal alteration, for instance via hydrothermal systems active for up to millions of years post‐impact.

Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier
AGU Advances, Volume 7, Issue 3, June 2026.Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

Mapping Quartz and Feldspar Areal Abundance and Grain Sizes Using Integrated VTIR Data
AGU Advances, Volume 7, Issue 3, June 2026.Abstract Mineral dust is sourced from arid regions around the globe, and its composition impacts regional and global environments by affecting radiation balance, cloud formation, nutrient deposition, and snowmelt. As such, mineral dust plays a key role in Earth's energy and biogeochemical budgets.

AGU Advances, Volume 7, Issue 3, June 2026.Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a nightsky optical phenomenon of great research interest in recent years. STEVE is recognized to be co‐located with a latitudinally narrow channel of fast westward ion drifts, also known as “subauroral ion drifts” (SAID).

AGU Advances, Volume 7, Issue 3, June 2026.Abstract The afternoon detached auroral arc is an important phenomenon in the subauroral region, reflecting coupling processes between the Earth's magnetosphere and ionosphere. Previous studies have not identified fine‐scale structures in such arcs, leaving the dynamics underlying their formation poorly understood.

The formation of molecular hydrogen in the interstellar medium
, 2010 H2 is the most abundant molecule in the interstellar medium and forms on the surface of interstellar dust grains. Laboratory studies have been conducted of HD formation on a dust grain analogue, which is a highly-oriented pyrolytic graphite surface ...

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions
Earth and Space Science, Volume 13, Issue 6, June 2026.Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.
