A symposium will be held on April 9-13, 2018, hosted by the Sellers Exoplanet Environments Collaboration at NASA Goddard Space Flight Center, Greenbelt, MD, USA. This symposium is a major international interdisciplinary conference in the emerging area of astrobiology covering astrophysical, physico-chemical, atmospheric and geological aspects of environments of early terrestrial planets with a focus on the impacts of the young Sun’s space weather on the precursors of life.

The understanding of impacts of external factors on prebiotic chemistry including UV and particle fluxes from the young Sun (and other active stars) along with the physio-chemical evolution of planetary atmospheres under the influence of their volcanic and tectonic activity will sharpen our definition of habitability on early terrestrial and terrestrial-type exoplanets. It will also help to specify environmental constraints for prebiotic atmospheric chemistry experiments that will better specify the most plausible pathways to the origin of life. This is only possible by forming a key linkage between astrophysics, heliophysics, planetary scientists, Earth science and the prebiotic chemistry/origin of life community.
