Project EOS

Earths in Other Solar Systems is a NASA-funded five year-duration astrobiology research program aiming to understand how and where habitable, earth-like planets with biocritical ingredients (volatiles and organics) form.

EOS is part of NASA’s Nexus for Exoplanetary System Science program, which carries out coordinated research toward to the goal of searching for and determining the frequency of extrasolar planets with atmospheric biosignatures in the Solar neighborhood.

Our interdisciplinary EOS team includes astrophysicists, planetary scientists, cosmochemists, material scientists, chemists and physicists.

The Principal Investigator of EOS is Daniel Apai (University of Arizona). The project’s lead institutions are The University of Arizona‘s Steward Observatory and Lunar and Planetary Laboratory.


EOS Project Overview



The EOS Institutional Consortium consists of the Steward Observatory and the Lunar and Planetary Laboratory of The University of Arizona, the National Optical Astronomical Observatory, the Department of Geophysical Sciences at the University of Chicago, the Planetary Science Institute, and the Catholic University of Chile.
