The Complexity of Deep Aqueous Fluids in Planetary Ultramafic Mantles

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Planetary volatiles cycle through a planet's crust, mantle, and atmosphere, playing a crucial role in surface processes and habitability. Discussions of planetary volatiles traditionally focus on water, carbon, nitrogen, and sulfur, but fluids in contact with silicate rocks and ultramafic mantles can contain significant amounts of magnesium ...

On the Dual Nature of Atmospheric Escape

The Astrophysical Journal
Planetary atmospheres cannot remain hydrostatic at all altitudes because they approach finite density at infinite radius, implying infinite mass. Classical treatments address this in two directions: either retain a hydrostatic structure while allowing ...

Interactions of Sublimated Frost With Volcanic Plumes: Modeling Io's SO2 Atmosphere Using the DSMC Method

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

A New Set of Atmosphere and Evolution Models for Brown Dwarfs and Giant Exoplanets

, 2019
The study of brown dwarfs and giant exoplanets is rapidly evolving as ever-improving instrumentation becomes sensitive to cooler objects. Accurate and reliable atmosphere and evolutionary models are important for placing mass and age constraints on these newly discovered objects, and understanding the rich chemistry and physics taking place in their ...

Weakening Tropical West Pacific Ascent Strength Reduces East Pacific Low Clouds via Lower Free‐Tropospheric Moisture Convergence

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Low clouds (LC) are the largest source of uncertainty in the climate response to increased CO2 ${\text{CO}}_{2}$ in global climate models. This is due to the multitude of factors that affect their behavior and how these are characterized across models.

A High-resolution Non-detection of Escaping Helium in the Ultrahot Neptune LTT 9779b: Evidence for Weakened Evaporation

The Astrophysical Journal Letters
The recent discovery of “ultrahot” ( P < 1 day) Neptunes has come as a surprise: some of these planets have managed to retain gaseous envelopes despite being close enough to their host stars to trigger strong photoevaporation and/or Roche lobe overflow ...

Out There No One Has a Right to Die

Bioethics, Volume 40, Issue 6, Page 565-572, July 2026.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...
