The Search for Alien Biosignatures: How Modern Technology is Detecting Life Beyond Earth!
An alien biosignature is any substance, structure, or phenomenon that provides scientific evidence of past or present life beyond Earth. As astrobiology matures, the search for these “fingerprints of life” has moved from speculation to high-precision science, focusing on atmospheric gases like oxygen and methane, surface pigments, and chemical disequilibria. With the deployment of the…
