    TLDR

    Astrobiology.com's September 16, 2026, roundup spans ancient bacterial genes, Ceres' surface and interstellar object 3I/ATLAS. The publisher reports that 3I/ATLAS's high deuterium-to-hydrogen ratio in water is consistent with a low-metallicity origin. It also highlights work on instruments for the Habitable Worlds Observatory, precision measurements for Theia and HWO, and a comparison of exoplanet-search methods using simulated PLATO data.
