💨 Abstract

Scientists led by Daniel Apai from The University of Arizona have developed a new model to assess whether exoplanets could support specific organisms beyond just the presence of water. This "quantitative habitability framework" considers factors like temperature and metabolism, making it easier to evaluate diverse planetary conditions and prioritize future research. The model has been tested on potential habitats for ancient Earth organisms like methanogens and cyanobacteria on exoplanets and moons, offering probabilities of habitat suitability.
