Smaller Than Earth Habitability Model (STEHM): The Lower Size Limit for Atmosphere Retention in the Habitable Zone
With recent advances in exoplanet observational techniques enabling the discovery of increasingly smaller planets, a crucial question emerges in the search for habitable planets: how small can a planet be […]
![Overview. (a) Composition of a bacterial cell by weight, with a breakdown of the chemical constituents [21]. About 40% of these compounds are not properly covered in existing datasets. (b) Multi-step workflow used to construct QCell, beginning with the selection of building blocks, followed by conformational sampling and fragment selection, pre-optimization with DFTB+MBD, and finally hybrid PBE0+MBD(-NL) calculations. (c) Coverage of molecular species at the PBE0+MBD(-NL) level of theory, including entries from existing databases and newly generated QCell data for nucleic acid fragments, lipids, sugars, solvated ions, and dimers. -- AI for Science](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/04/Mapping-The-Molecules-Of-Life.png?resize=1200%2C719&ssl=1)
