NASA Hubble Fellowship Program





The 2018 Fellows have been announced.

The NASA Hubble Fellowship Program (NHFP) supports outstanding postdoctoral scientists to pursue independent research in any area of NASA Astrophysics, using theory, observation, experimentation, or instrumental development.  

The new NHFP preserves the legacy of NASA’s previous postdoctoral fellowship programs; once selected, fellows are named to one of three sub-categories corresponding to NASA’s “big questions:”  

How does the Universe work? – Einstein Fellows
How did we get here? – Hubble Fellows
Are we alone? – Sagan Fellows

The Space Telescope Science Institute administers the NHFP on behalf of NASA, in collaboration with the NASA Exoplanet Science Institute (NExScI) at the California Institute of Technology and the Chandra X-ray Center at the Smithsonian Astrophysical Observatory.

Applications for fellowships, to begin in the fall of 2019, will be accepted starting in early September 2018. We anticipate offering up to 24 fellowships this year, contingent upon funding. The NHFP will be open to applicants of any nationality who have earned their doctoral degrees on or after January 1, 2016, in astronomy, physics, or related disciplines.

NHFP fellowships are tenable at U.S. host institutions of the fellows' choice, subject to a maximum of two new fellows per host institution per year, with no more than five fellows being hosted by a given institution in any three-year period (where the cumulative count begins with the 2018 fellows). The duration of the fellowship is up to three years: an initial one-year appointment, and two annual renewals, contingent on satisfactory performance and availability of NASA funds.

Detailed program policies and application instructions may be found in the official Announcement of Opportunity.
