NASA Hubble Fellowship Programme supports promising postdoctoral astrophysicists to pursue independent research relevant to NASA Astrophysics using theory, observation, experimentation, or instrument development. The program assigns fellows to Einstein, Hubble, or Sagan categories aligned with NASA’s ‘‘big questions.’’
The NASA Hubble Fellowship Program is administered for NASA by the Space Telescope Science Institute (STScI) in collaboration with JPL, NExScI, and the Chandra X-ray Center. Detailed policies and application instructions are available in the Announcement of Opportunity linked on the program site.

Frequently Asked Questions (FAQs)
Here are the most frequently asked questions about the NASA Hubble Fellowship Programme. These answers cover eligibility, benefits, deadlines, what to submit, and how to apply based on the program pages.
What is the NASA Hubble Fellowship Program?
The NASA Hubble Fellowship Program (NHFP) fosters excellence and leadership in astrophysics by supporting exceptionally promising and innovative early-career astrophysicists. It supports postdoctoral scientists to pursue independent research that contributes to NASA Astrophysics across theory, observation, experimentation, or instrument development.
Who administers the NASA Hubble Fellowship Programme?
The NHFP is administered for NASA by the Space Telescope Science Institute (STScI) in collaboration with the Jet Propulsion Laboratory (JPL), the NASA Exoplanet Science Institute (NExScI), and the Chandra X-ray Center (CXC). The program page provides contact and administrative information.
Which research areas are eligible for the fellowship?
Eligible projects contribute to NASA Astrophysics and may use theory, observation, experimentation, or instrument development. Fellows are assigned to sub-categories—Einstein, Hubble, or Sagan—aligned with NASA’s broad astrophysics questions.
Where are fellowships tenable?
NHFP fellowships are tenable at U.S. host institutions of the fellow’s choice. Host institutions must follow the Host Employment Policy and there is a limit on new fellows per host institution per year as described on the program page.
How long does the NASA Hubble Fellowship Programme last?
The duration of the fellowship is up to three years: an initial one-year appointment with two annual renewals contingent on satisfactory performance and availability of NASA funds. This information is provided on the NHFP program page.
What are the important application dates for the 2027 cycle?
Important dates listed on the NHFP page include: Announcement of Opportunity issued September 8, 2026; application website opens September 8, 2026; applications due October 28, 2026 at 7:00 PM EDT; letters of reference due November 4, 2026 at 7:00 PM EST; award offers February 2027; public announcement March 2027.
How do I apply for the NHFP?
Applicants should review the Announcement of Opportunity on the NHFP page and apply via the NHFP application website. The program page includes a direct link to the application portal (https://cosmos.ipac.caltech.edu/nhfp/application.php) and application resources.
