Welcome to the NASA Exoplanet Science Institute

The NExScI is a science operations and analysis service organization for NASA Exoplanet Exploration Program projects and the scientists and engineers that use them. The NExScI facilitates the timely and successful execution of exoplanet science by providing software infrastructure, science operations, and consulting to Exoplanet Exploration Program projects and their user communities.

The NExScI is sponsored by NASA's Exoplanet Exploration Program and operated by the California Institute of Technology (Caltech) in coordination with the Jet Propulsion Laboratory (JPL).

NExScI Goals and Mission

The NASA Exoplanet Science Institute (NExScI) is a science analysis service organization for the NASA Exoplanet Exploration Program projects and the scientists and engineers who use them. For additional information on NASA's search for extrasolar planets, please visit PlanetQuest.

Specifically, NExScI administers and schedules of NASA's portion of time on the Keck telescopes, develops and operates the NASA Exoplanet Archive, administers the Sagan Postdoctoral Fellowship Program, runs the Sagan Summer Workshop, supports the Large Binocular Telescope Interferometer (LBTI) and additional projects in the Exoplanet Exploration Program.

NExScI has developed and maintains several public astronomy data archives and software tools. New datasets and data analysis tools are added to the archives as they become available. These archives include:

NExScI provides operational software infrastructure and support; archiving of and access to observational data; and consultation for all stages of an experimental project, from concept development and proposal writing to implementation and analysis.

NExScI is operated by the California Institute of Technology for the National Aeronautics and Space Administration and the Jet Propulsion Laboratory.
