A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

On the Significance of the Thick Disks of Disk Galaxies

open access: yesThe Astrophysical Journal Supplement Series
Thick disks are a prevalent feature observed in numerous disk galaxies, including our own Milky Way. Their significance has been reported to vary widely, ranging from a few percent to 100% of the disk mass, depending on the galaxy and the measurement ...

Oxychlorine Species on Mars: A Review

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Relevance of Murchison Widefield Array Interplanetary Scintillation Observations to Heliospheric Transient Catalogs

open access: yesSpace Weather, Volume 23, Issue 12, December 2025.
Abstract We have conducted a comprehensive comparison of interplanetary scintillation (IPS) observations taken by the Murchison Widefield Array (MWA) with several heliospheric transient event catalogs, over a time period of 7 months during solar minimum.

Aeos: The Impact of Population III Initial Mass Function and Star-by-star Models in Galaxy Simulations

open access: yesThe Astrophysical Journal
We explore the effect of variations in the Population III initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the A eos simulations. We compare simulations with two different Population III IMFs: M _char  =

Variations of the Virome in Raw and Treated Water: A One‐Year Follow‐Up at Six Different Drinking Water Treatment Plants

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
This paper describes monitoring of outgoing water from drinking water treatment plants, geographically spread over half of Sweden and sampled every other month for 1 year. We found differences in the virome from the different water sources from each plant as well as differences in virus size and seasonal variation, where we also could detect viruses in

Many Elements Matter: Detailed Abundance Patterns Reveal Star Formation and Enrichment Differences among Milky Way Structural Components

open access: yesThe Astronomical Journal
Many nucleosynthetic channels create the elements, but two-parameter models characterized by α and Fe nonetheless predict stellar abundances in the Galactic disk to accuracies of 0.02–0.05 dex for most measured elements, near the level of current ...
