Near-perihelion observations of interstellar comet 3I/ATLAS with JUICE/MAJIS reveal CO2-driven activity, a ~10% CO2/H2O ratio, and tentative evidence for complex organic material in coma dust.

SCAT DR1 delivers 1810 spectra of 1330 transients with classifications, fitted light curves, new redshifts for many host galaxies, and host properties as a testbed for photometric classification pipelines.
Post-perihelion spectra of 3I/ATLAS show reduced C2 depletion, asymmetric CN/metal outgassing, metal-CO correlation, and an unexplained [O I] residual after standard parent subtraction.
3I/ATLAS lost roughly 1–7 meters of its surface and ~10^9–10^10 kg of mass during its Solar System passage, based on fits to observed gas production rates.
