Microbial endolithic community at Meteor Crater
Meteoritics &Planetary Science, Volume 61, Issue 6, Page 955-962, June 2026.Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Numerical estimation of the capture ability of Neptunian mean motion resonances
Astronomy & AstrophysicsResonant populations of trans-Neptunian objects serve as crucial dynamical archives for unraveling the early migratory history of the Solar System. A quantitative assessment of the capture efficiency into various mean motion resonances (MMRs) during ...

Anhydrous minerals in asteroid Bennu: Evidence for well‐preserved primordial components
Meteoritics &Planetary Science, Volume 61, Issue 6, Page 963-986, June 2026.Abstract Aqueously altered carbonaceous astromaterials are dominated by secondary minerals, but a minor fraction of primary, anhydrous silicates and oxides escape alteration, offering insight into the original composition of asteroid parent bodies. We report the mineralogy, petrology, mineral chemistry, and oxygen isotopes of anhydrous minerals—50 ...

What is a lunar standstill? Problems of accuracy and validity in ‘the Thom paradigm’. [PDF]
, 2006 North West European late Neolithic and Early Bronze Age (EBA) monumentalalignments on the sun’s solstices and the moon’s standstills were firstsystematically studied by Thom (Thom 1971).

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1077-1094, June 2026.Abstract Samples returned by NASA's OSIRIS‐REx mission from the carbonaceous asteroid (101955) Bennu hold clues about conditions in the early solar system and the formation of planetary bodies. Initial investigation of Bennu samples found that they are rich in phyllosilicates and other secondary minerals formed during aqueous alteration of a larger ...
