2026 NASA Hubble Fellowship Program Application Deadline 29 October 2025
On behalf of the NASA Astrophysics Division, the Space Telescope Science Institute (STScI) announces the call for applications for postdoctoral fellowships under the NASA Hubble Fellowship Program (NHFP) beginning in the fall of 2026.
The NHFP supports postdoctoral scientists performing independent research that contributes to NASA Astrophysics. The research may be theoretical, observational, and/or instrumental. If your application is successful and you accept our offer, you will become an NHFP Einstein, Hubble or Sagan fellow, depending on the area of your research.
The NHFP is open to applicants of any nationality who have or will have completed all requirements for their doctoral degree on or after 1 January 2022 in astronomy, physics or related disciplines. 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. The NHFP is administered for NASA by the Space Telescope Science Institute (STScI) in collaboration with the Jet Propulsion Laboratory and NASA Exoplanet Science Institute (NExScI) at the California Institute of Technology and the Chandra X-ray Center at the Smithsonian Astrophysical Observatory.
We anticipate offering up to 24 NHFP Fellowships this year. The Fellowships are tenable at a U.S. host institution 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. Host institutions must have verified their compliance with the NHFP employment policy. The policy and a list of those hosts can be found on the host institutions webpage.
The Announcement of Opportunity, which includes detailed program policies and application instructions, is available at the NHFP website. The application submission page will be open from 2 September 2025 until the application deadline on 29 October 2025.
Applicants should follow the instructions given in the Announcement of Opportunity and also examine the Frequently Asked Questions linked from the main NHFP page. Please send any further inquiries about the NHFP to nhfp@stsci.edu.
