Several papers on the isotopic composition of 3I/ATLAS on the arxiv today, with, e.g., 12C/13C being ca. 50% higher than measured in all solar system materials (D/H, 14N/15N too). Before, these kind of measurements were only possible in micron-scale presolar grains from primitive meteorites.🪐☄️ 1/11
