He called the discovery a “paradigm shift” in the search for life elsewhere in the universe. Given their size and proximity to their low-intensity star, all three planets may have regions at temperatures within a range suitable for sustaining liquid water and life, the study concluded. Their...
The habitability of a planetary environment is defined by the intrinsic environmental requirements of life, which, in turn, arise from the most universal attributes of life itself. Key environmental requirements include a suitable solvent, the chemical building blocks of life, biologically useful ...
