Dust grain size distributions evolve from large-grain dominated at high redshift to MRN-like at low redshift, driven primarily by shattering and ISM accretion after stars supply initial large grains, reproducing z=0 dust masses and Milky Way extinction properties.

Second-epoch JWST/MIRI-MRS mid-IR spectra of SN 1987A show little overall dust evolution but inner equatorial ring fading, rapid ejecta line changes, some ER line fading, first mid-IR H2 from ejecta, and evidence that dense Fe-rich ejecta has reached the reverse shock.
Radial velocity data reveal a 310-day orbital period in NaSt1 with opposing phases in two groups of emission lines, supporting its nature as a post-mass-transfer massive binary system.
JADES DR5 delivers a public catalog of Bayesian-inferred stellar masses, SFRs, SFHs, dust, metallicities, and AGN contributions for ~500k galaxies via Prospector with an evolving SFMS prior.
N6946-BH1's remnant is roughly 10 times fainter than its progenitor while stellar merger remnants are 10-100 times brighter, and asymmetric dust cannot explain the difference.
New NIR and optical spectra of the outbursting comet 12P/Pons-Brooks detect crystalline water ice at 140-170 K and gas ratios indicating typical C3 but depleted C2, with outburst kinetic energy of ~8e3 J/kg supporting amorphous ice crystallization as the trigger and a refractory-to-ice mass ratio of
Spectroscopic observations of disintegrating comet C/2019 Y4 (ATLAS) classify it as a typical Oort cloud comet with less dust, where porous dust accounts for its slightly red reflectivity gradient of ~5% per 1000 Å.
