The search for exoplanets has shifted from discovery to characterization, with advancements such as the James Webb Space Telescope enabling the detection of biosignatures. Astrobiologists recognize the limitations of using Earth’s life as a template and are expanding the search to include biosignatures indicative of primitive life forms. A recent study identified water, carbon monoxide, and methane as potential biosignatures for Archean-like planets orbiting red dwarf stars. This research broadens the scope of biosignature detection and increases the likelihood of discovering life beyond Earth.
