Red dwarf star light may not support oxygen-producing alien plants

Red dwarf stars may not provide the quality of light needed for oxygen-producing alien plant life, according to new research. A study suggests that while red dwarfs are common and host many planets, their light lacks the necessary energy and thermodynamic quality to drive essential biological processes like water splitting for photosynthesis. This research indicates that Earth-like biospheres are difficult to sustain around red dwarfs, potentially making sun-like stars a better target for finding oxygen-rich alien life.
