Newswise — NASA has selected 24 new Fellows for its prestigious NASA Hubble Fellowship Program (NHFP). The program enables outstanding postdoctoral scientists to pursue independent research across NASA Astrophysics, using theory, observation, experimentation, or instrument development. Each fellowship provides the awardee up to three years of support.

The NHFP is one of the highlights of NASA's pursuit of excellence in space science, and preserves the legacy of NASA's previous postdoctoral fellowship programs – the Hubble, Einstein and Sagan Fellowships. Once selected, fellows are named to one of three sub-categories corresponding to three broad scientific questions NASA has sought to answer about the universe:

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

"I am excited that this outstanding group of young scientists has accepted NASA Hubble Fellowships," said Paul Hertz, Astrophysics Division director at NASA Headquarters in Washington, D.C. "I am confident that the research they do will address the most compelling questions in astrophysics and have an impact on our field far beyond the three-year duration of their Fellowships."

The newly selected NHFP Fellows will begin their programs in the fall of 2020 at a university or research center of their choosing in the United States. The list below provides the names of the 2020 awardees, their institutions, and their proposed research topics.

An important part of the NHFP are the Symposia, which allow fellows the opportunity to present results of their research, and to meet each other and the scientific and administrative staff who manage the program. This year's symposium is scheduled to take place the week of September 21, 2020 at the Space Telescope Science Institute (STScI) in Baltimore, Maryland.

STScI 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.
