Characterization of Dust in Saturn's Rings Using Cassini Spacecraft Data

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The dust distribution in Saturn's rings is investigated using dust impacts registered by the Radio and Plasma Wave Science (RPWS) instrument onboard the Cassini spacecraft. Dust impacts, recorded as spiky signals in electric field waveforms, are used to determine profiles of impact rates and amplitudes of spikes during individual equatorial ...

Effects of Comet Encke's Meteoroid Stream on the Seasonal Variation of Mercury's Ca Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mercury's calcium (Ca) exosphere, observed by NASA's MESSENGER mission, exhibits high temperatures (>50000 K) and pronounced seasonal variability, with its source mainly on the dawn side. Enhanced Ca emission near True Anomaly Angle (TAA) ∼25° and ∼150° has been attributed to Comet 2P/Encke meteoroid streams.

Kineochelins—A New Group of Siderophores From an Antarctic Bacterium

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Genome‐guided analysis of an Antarctic Actinokineospora strain led to the discovery of kineochelins, a new group of siderophores involved in iron sequestration and microbial competition. Kineochelin production inhibits co‐occurring bacteria and clinically relevant yeasts, highlighting Antarctic microorganisms as promising sources of bioactive natural ...

Configuration of single giant planet systems generating ‘Oumuamua-like interstellar asteroids

Monthly Notices of the Royal Astronomical Society
ABSTRACT The first discovered interstellar small object, ‘Oumuamua (1I/2017 U1), presents unique physical properties of extremely elongated geometric shape and dual characteristics of an asteroid and a comet. These properties suggest a possible origin through tidal fragmentation, which posits that ‘Oumuamua was produced through intensive

Potential of VIS‐IR imaging spectroscopy and SEM‐EDS and EMPA to map the mineralogical composition of NWA 7317 (CR6)

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1026-1044, June 2026.
Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.
