is open to applicants from <strong>all nationalities</strong>.</p> <p>To be eligible, applicants must have completed or be expected to complete all requirements for their doctoral degree <strong>on or after January 1, 2023</strong>.</p> <p>The doctorate must be in:</p> <ul> <li>Astronomy</li> <li>Physics</li> <li>Or a related discipline</li> </ul> <p>The program is therefore specifically designed for researchers at the postdoctoral stage who have recently completed, or are about to complete, their doctoral training.</p> <h2>Research Areas</h2> <p>NHFP fellows are expected to conduct independent research that contributes to <strong>NASA Astrophysics</strong>.</p> <p>The program allows research to be theoretical, observational, instrumental, or a combination of these approaches.</p> <p>This broad research structure means that applicants working across different areas of astrophysics may be able to develop fellowship proposals aligned with their specific scientific interests and expertise.</p> <p>The fellowship designation awarded to a successful applicant — Einstein, Hubble, or Sagan — will depend on the applicant&#8217;s research area.</p> <h2>Fellowship Duration</h2> <p>The NASA Hubble Fellowship can last for <strong>up to three years</strong>.</p> <p>The fellowship is structured as:</p> <ol> <li><strong>Initial one-year appointment</strong></li> <li><strong>First annual renewal</strong></li> <li><strong>Second annual renewal</strong></li> </ol> <p>The two renewals are contingent on:</p> <ul> <li>Satisfactory performance</li> <li>Availability of NASA funding</li> </ul> <p>Therefore, although the program offers the possibility of a three-year fellowship, continuation beyond the initial appointment is not described as unconditional.</p> <h2>U.S. Host Institution</h2> <p>NHFP Fellowships are tenable at a <strong>U.S. host institution of the fellow&#8217;s choice</strong>.</p> <p>However, the program places limits on the number of new fellows that can be hosted by an individual institution.</p> <p>The stated policy allows:</p> <ul> <li>A maximum of <strong>two new fellows per host institution per year</strong></li> <li>One new fellow for institutions that hosted two new fellows during the previous year</li> </ul> <p>Host institutions must also have verified compliance with the NHFP employment policy.</p> <p>Applicants should therefore review the official list of verified host institutions before finalizing their host-institution plans.</p> <h2>Number of Fellowships Available</h2> <p>For the 2027 cycle, the program anticipates offering <strong>up to 24 NHFP Fellowships</strong>.</p> <p>The actual number of fellowships offered can therefore be up to 24 for the cycle.</p> <p>Because this is a competitive postdoctoral research program, applicants should carefully follow the official application instructions and prepare their materials according to the requirements in the Announcement of Opportunity.</p> <h2>Organizations Administering the NHFP</h2> <p>The program is administered for NASA by the <strong>Space Telescope Science Institute (STScI)</strong>.</p> <p>STScI administers the program in collaboration with:</p> <ul> <li>The <strong>Jet Propulsion Laboratory (JPL)</strong></li> <li><strong>NASA Exoplanet Science Institute (NExScI)</strong> at the California Institute of Technology</li> <li>The <strong>Chandra X-ray Center</strong> at the Smithsonian Astrophysical Observatory</li> </ul> <p>This collaborative structure connects the fellowship with several major institutions involved in astrophysical research.</p> <h2>What Fellows Will Do</h2> <p>The central purpose of the NHFP is to support postdoctoral scientists conducting <strong>independent research</strong>.</p> <p>Research may involve theoretical investigations, observations, instrumentation, or combinations of these approaches.</p> <p>The independent nature of the fellowship is particularly important because it allows postdoctoral researchers to develop their own research programs and contribute to the broader scientific objectives of NASA Astrophysics.</p> <p>Applicants should therefore ensure that their proposed research clearly demonstrates its relevance to astrophysics and its contribution to the scientific objectives of the program.</p> <h2>Application Timeline
