457P shows dust activity without detectable H2O, CO, CO2, or CH3OH, with Q(H2O) < 2e24 molecules/s, indicating it may be more volatile-depleted than other main-belt comets.

Tianwen-1 provided the first out-of-plane imaging of 3I/ATLAS, indicating large dust grains (hundreds of micrometers) ejected at 3-10 m/s with steady-state outflow and a mass loss rate of about 1000 kg/s.
Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
JWST observations of 133P/Elst-Pizarro yield water outgassing rates of (1.9 ± 0.6) × 10^25 and (1.4 ± 0.4) × 10^25 molecules/s at true anomalies 8° and 37.4°, with hypervolatile depletion Q(CO2)/Q(H2O) < 0.009 and an average log(Afrho/Q(H2O)) = -24.6 ± 0.2 across three MBCs.
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
