  • The public is weighing in on the names that will annotate maps of a world no one has ever seen.

  • New Horizons
    The SETI Institute is deeply involved with the New Horizons mission to Pluto, and several of our scientists are awaiting results that could truly revolutionize understanding of the solar system’s early history.
