JWST observations indicate that interstellar comet 3I/ATLAS has dust dominated by amorphous silicates similar to the ISM, unlike the crystalline silicate-rich dust in Solar System comets.

The ~34 Myr old M4.5 star J0446B hosts a long-lived, hydrocarbon-dominated primordial disk with a gas-phase C/O ratio of at least 2.
JWST spectra of comet 81P/Wild 2 give new gas, isotope, and dust-composition measurements, and show how they relate to Stardust's returned samples.
Extreme debris disks are a distinct subclass produced by large (Moon- to Mars-sized) collisions, with silica-rich mineralogy tracing energetic embryo impacts during terrestrial planet formation and high-W10 silica-poor systems marking later dynamical instability.
New ultraviolet abundances for two white dwarfs, combined with a re-analysis of eight systems, support a tentative correlation between the Mg/Si ratio of accreted exoplanetary material and whether its dust is olivine- or pyroxene-rich.
CLUES is a non-parametric clustering workflow that combines Sequencer distance matrices with hierarchical clustering and silhouette scoring to classify debris disk and mineral spectra.
