The highly competitive NASA Hubble Fellowship Program (NHFP) recently named 24 new fellows to its 2024 roster. The program fosters excellence and inclusive leadership in astrophysics by supporting a diverse group of exceptionally promising and innovative early-career astrophysicists.

The NHFP enables outstanding postdoctoral scientists to pursue independent research in any area of NASA Astrophysics, using theory, observations, simulations, experimentation, or instrument development. Over 520 applicants vied for the 2024 fellowships. Each fellowship provides the awardee up to three years of support at a U.S. institution.

Once selected, fellows are named to one of three sub-categories corresponding to three broad scientific questions that NASA seeks to answer about the universe:

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

“The NASA Hubble Fellowship Program is a highly competitive program, and this year’s cadre of Fellows are to be congratulated on their selection,” said Mark Clampin, director of the Astrophysics Division at NASA Headquarters in Washington, D.C. “They will undoubtably be future leaders in the field of Astronomy and Astrophysics.”

The list below provides the names of the 2024 awardees, their fellowship host institutions, and their proposed research topics.

An important part of the NHFP is the annual Symposium, which allows Fellows the opportunity to present results of their research, and to meet each other and the scientific and administrative staff who manage the program. The 2023 Symposium was held at the Center for Astrophysics in Cambridge, Massachusetts. Science topics ranged through exoplanets, gravitational waves, fast radio bursts, cosmology and more. Non-science sessions included discussions about career paths, fellows’ plans for mentoring and to increase diversity, equity, and inclusion in the NHFP, as well as an open mic highlighting an array of talents outside of astrophysics.

The Space Telescope Science Institute in Baltimore, Maryland administers the NHFP on behalf of NASA, in collaboration with the Chandra X-ray Center at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, and the NASA Exoplanet Science Institute at Caltech/IPAC in Pasadena, California.
