Finding, Exploring and Characterizing Terrestrial Exoplanets: The Next Frontier

Session ID#: 75474

Session Description:
This session is a discussion of the potential of new and future facilities and modeling efforts designed to detect, image and characterize Earth-size and super-Earth terrestrial exoplanets, studying their formation, evolution and also the existence of possible biospheres.  Topics to be covered in this session include instrument requirements and technologies to detect these exoplanets; strategies for target selection and prioritization; signs of exoplanet habitability and global biosignatures that can be sought with upcoming instrumentation; impacts of planetary system properties; and future ground-based and space telescope architectures.
