[B-CG04] Decoding the history of the Earth-like planets: From their birth to the present

Fri. May 29, 2026 3:30 PM - 5:00 PM Exhibition Hall Special Setting (5) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson:Shiraishi Fumito(Earth and Planetary Systems Science Program, Graduate School of Advanced Science and Engineering, Hiroshima University), Nagao Ryosuke(The University of Tokyo School of Science Department of Earth and Planetary Science)

This session will bring together the latest research results from various approaches, including observations, exploration, field surveys, chemical analysis, experiments, and theoretical calculations, on the evolution and geological processes of Earth and exoplanets from their birth to the present, and will comprehensively discuss the origin and internal evolution of exoplanets and Earth, the causal relationships and interactions between surface environmental changes and the birth and evolution of life. A wide range of related topics are welcome, including astronomy, planetary science, geology, tectonics, igneous and metamorphic petrology, stratigraphy and paleontology, evolution, environmental science, and geochemistry.
