Announcements and Introduction
The NASA Hubble Fellowship Program (NHFP) supports outstanding postdoctoral scientists to pursue independent research which contributes to NASA Astrophysics, using theory, observation, experimentation, or instrument development.
The NHFP preserves the legacy of NASA’s previous postdoctoral fellowship programs.
Once selected, fellows are assigned 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 are now closed for fellowships to begin in fall 2021. We anticipate offering up to 24 fellowships this year, contingent upon funding. The NHFP is open to applicants of any nationality who have earned their doctoral degrees in astronomy, physics, or related disciplines on or after January 1, 2018, or who will receive their degree before September 2021. Under certain circumstances, this date may be extended back to January 1, 2017. See the Announcement of Opportunity for further information.
NHFP fellowships are tenable at U.S. host institutions of the fellow's choice, subject to a maximum of two new fellows per host institution per year, and no more than five fellows at any single host institution, except for short periods of overlap. 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.
