摘要：20+ years after the discovery of the first exoplanet, scientists are observing Earth-mass exoplanets close to the 'habitable zones' of various stars. This effort could potentially answer the long standing question: Are we alone in the Universe?
With the expected rapid pace of discoveries, it will be useful to systematically examine the requirements for a planet to be defined 'habitable'. And it will be wise to look at planet habitability from an evolution point of view. Moreover, it will be useful to discuss what possible signs of life on exoplanets are and how to search for them with the environment of PHZ and their evoution in mind. In this talk the most recent developments on planetary habitability and biosignature detections will be discussed.
