It’s official and it’s named. The object, provisionally designated A11pl3Z, showed ‘fuzziness’ (nebulosity, likely from activity) and was then given the comet designation C/2025 N1. Official discovery credit goes to the ATLAS network, Chile site (Rio Hurtado)- hence, the third designation.… Read More »Interstellar Object 3I/ATLAS
