Biosignatures

Biosignatures are any measurable or detectable signs of life that can be used to infer the presence of living organisms. In the context of space and astronautical engineering, biosignatures are used to search for extraterrestrial life on other planets or moons. These signs can include the presence of certain molecules, such as oxygen or methane, that are produced by living organisms, as well as patterns of light absorption or reflection that are indicative of biological processes. The development of biosignature detection techniques is crucial for the success of future space missions that aim to search for life beyond Earth.
