Description and modeling of the Jiddat al Harasis 091 L5 strewn field

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 107-121, January 2026.
Abstract With a size of 51.2 × 7.2 km, the 10.9 ± 1.7 ka old Jiddat al Harasis 091 L5 chondrite strewn field is the largest known in Oman. It consists of more than 700 meteorites with a total mass of >4.5 tons from which the largest six stones of >100 kg to 1.5 tons make up two thirds of the total mass.

Modeling enstatite chondrites: Reduced rocks with a pinch of oxidized material (affected by varying H2O(g)) derived from planetesimals shocked during the epoch of giant–planet migration

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.
Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

Candidate Main-belt Asteroids for Surface Heterogeneity

The Astronomical Journal
Abstract Large terrestrial bodies in our solar system like the Earth, Mars, Mercury, and the Moon exhibit geologically complex surfaces with compositional heterogeneity. From past studies using large telescopes and spacecraft, it was shown that asteroids with diameters larger than 100 km also show surface heterogeneity at hemispheric ...

Occurrence and characterization of nanosulfide‐rich regions on asteroid Ryugu: Insights from mackinawite and pyrrhotite

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 168-181, January 2026.
Abstract Samples returned from asteroid Ryugu by the Hayabusa2 mission are dominated by fine‐grained matrix material made of phyllosilicates and nanosulfides. Here, we report the mineralogical, textural, and chemical characteristics of nanosulfide‐rich regions identified in Ryugu particles.

Categorization of Spatial and Temporal Ejecta Outcomes in Binary Systems Based on Variations of the Didymos System

The Planetary Science Journal
With the increasing number of binary asteroid systems being discovered, ejecta studies must expand from solely investigating single-body systems to modeling more complex multiple-body systems. For example, the Double Asteroid Redirection Test provides an

The Martyrdom of Nadezhda Kurchenko: Soviet Hero Cults and the Spiritual Turn in Late Socialism

The Russian Review, Volume 85, Issue 1, Page 69-87, January 2026.
Abstract This article argues that the spiritual turn in Soviet atheism under Brezhnev provided a meaningful solution to the problems of producing heroes when self‐sacrificing martyrs were losing their appeal. To support this claim, I examine the story of Nadezhda Kurchenko, a nineteen‐year‐old flight attendant killed by two hijackers on an Aeroflot ...

Deep‐soil sampling in Chile reveals a new elateroid beetle family, Badmaateridae fam. nov. (Coleoptera)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
Genomic data support the definition of a new elateroid family, Badmaateridae fam. nov., with Badmaater chilensis gen. nov. sp. nov. as the only representative. Badmaateridae is sister to an extensive clade containing fireflies, soldier beetles, net‐winged beetles and click beetles.
