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.

JWST mid-IR observations of interstellar comet 3I/ATLAS yield the first direct methane detection and confirm strongly enhanced CO2:H2O mixing ratios relative to solar system comets.
JWST/MIRI survey of 2-6 Myr Upper Scorpius disks finds diverse chemotypes, 10-1000x lower water luminosities, and evidence that outer dust traps control inner-disk chemistry.
Older Upper Scorpius disks show reduced molecular emission and hints of higher inner-gas C/O ratios than young disks, indicating chemical evolution consistent with pebble drift.
New JWST observations of Centaurus A detect H2 lines up to S(8) and map a warm molecular disk with a 20-pc cavity aligned to the jet, filamentary high-excitation structures, S-shaped kinematics, and an inward streamer, yielding a warm H2 mass of 5.6e5 solar masses heated by shocks.
JWST data reconstructs the inner ejecta of SNR 0540-69.3 as two similar-sized fragmented lobes, implying a ~300 km/s pulsar kick under symmetry assumption and confirming low-velocity hydrogen mixing in a Type II explosion.
JWST observations of Sz 65 and Sz 66 reveal higher cold-to-hot water ratios in the secondary disk, attributed to its unstructured dust disk enabling efficient pebble drift across the snow line.
JWST spectra of EC 53 indicate CO fundamental and H2O bending absorption weaken by ~2 during burst due to continuum dilution, with relative veiling yielding hot-continuum ratios of 2.9 and 1.71 and viscous-disk accretion-rate ratios of ~3.6 and ~2.0.
SKA will detect emission from heavy molecules and prebiotic species in obscured disk regions to constrain initial chemical conditions for planet formation.
