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.

First quantitative JWST study of weak ice bands in 21 protostars finds CH4 likely dominant at 7.67 um and HCOO- plus other COMs at 7.24/7.40 um, indicating ubiquity of complex ices.
First pixel-by-pixel JWST absorption maps of multiple ice species toward six Class 0 protostars reveal abundance variations from heating and outflows, with total composition matching prestellar formation models covering ~90% of inventory.
No change detected in ice absorption bands of EC 53 between phases, with ice abundances higher than typical for embedded protostars.
The pyRate model requires nondiffusive chemistry to form observed S-bearing species in irradiated CO2:CS2 ice but overpredicts OCS, CS and SO while underpredicting SO2 and sulfur allotropes.
