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.

Analysis of eight 2021 outbursts on comet 7P/Pons-Winnecke using ground-based photometry yields ejecta masses of 10^5-10^6 kg and normalized rates comparable to several other comets but discrepant with 67P spacecraft data.
Rubin Observatory delivers the earliest large-telescope astrometry and grizy photometry of interstellar comet 3I/ATLAS, including colors and a dust-to-nucleus cross-section ratio lower limit.
