The proceedings of IAU Symposium 393 bring together leading voices in planetary science, exoplanet research, and astrobiology, with a special focus on discoveries enabled by the James Webb Space Telescope (JWST). Topics covered include atmospheric characterization of exoplanets, detection of biosignatures, the dynamics of protoplanetary disks, and studies of Solar System bodies such as comets and Kuiper Belt objects. This volume also highlights international initiatives in public engagement and education, demonstrating how planetary science is expanding globally and becoming more inclusive. Featuring insights from researchers and educators across multiple continents, this collection captures the multidisciplinary essence of planetary exploration and the search for life beyond Earth. It is a valuable resource for astronomers, planetary scientists, astrobiologists, and educators who wish to understand the scientific breakthroughs and collaborative spirit driving a new era of discovery.
