Description
The NASA Hubble Fellowship Program (NHFP) supports promising postdoctoral scientists pursuing independent research in any area of NASA Astrophysics. It aims to foster excellence and leadership through theory, observation, experimentation, and instrument development. STScI administers the program for NASA in collaboration with the Jet Propulsion Laboratory, NASA Exoplanet Science Institute at Caltech, and Chandra X-ray Center at the Smithsonian Astrophysical Observatory.
Fellows conduct research at eligible host institutions in the United States or its territories. Proposed work must connect to NASA Astrophysics scientific or technical goals and be compatible with the host’s research activities, but need not address a specific NASA mission. Solar System, Sun, and Earth research can qualify when its astrophysics relevance is clear. Selected researchers receive Einstein, Hubble, or Sagan designations according to their research topics.
