Scope 
Astrobiology is an interdisciplinary scientific field that investigates the origin, evolution, distribution, and future of life in the universe. Scientists have long explored the origins, transfer, and complexification of essential elements and materials that give rise to biological systems on Earth and beyond, yet a comprehensive understanding of these phenomena remains elusive. Thus, it is vital to establish connections across fields like astronomy, Earth and planetary sciences, chemistry, and biology. These disciplines provide unique insights into the universe's dynamics, the intricate systems governing exoplanets and the solar system, and the foundational building blocks of life. By bridging these areas of study, we can gain a more comprehensive view of life in the cosmos and expand the boundaries of scientific discovery.
  This astrobiology session offers a comprehensive overview for scientists engaged in diverse research themes, such as planetary system formation and evolution, exoplanet surface environments and biosignatures, chemical evolution and geochemistry in the solar system, the origins of biomolecules essential for life, and life detection strategies for space exploration. This session aims to foster productive discussions across these themes, ultimately supporting a shared vision for the future of astrobiology.
