Abstract:
Earth provides the only known example of a habitable world, yet its history reveals that life has persisted through dramatic climatic, chemical, and geological changes. This talk explores how studies of Earth’s evolution inform our understanding of habitability elsewhere in the universe. By examining how life co-evolves with its planetary environment, we can better interpret the signatures of habitability and biosignatures on other worlds. The discussion includes recent results from Mars exploration, icy moon research, and exoplanet studies, highlighting the scientific strategies guiding the search for life beyond Earth.
