NASA Hubble Fellowship Program Update

New Fellows Selected

The NASA Hubble Fellowship Program (NHFP) fellowship provides for three years of salary and research support at a U.S. host institution of the fellow's choosing, subject to restrictions that limit the number of fellows at any one institution. Once selected, fellows are named to one of three sub-categories (informally known as flavors) corresponding to three broad scientific questions NASA has sought to answer about the universe:

In this way the NHFP builds upon the legacy of the three formerly independent NASA fellowships of the same names.

In March, NASA announced the class of 2020 Fellows. The new fellows, their host institutions and their proposed research programs are:

Originally, the Einstein, Hubble, and Sagan programs were run separately by the Chandra X-ray Center (CXC), the Space Telescope Science Institute (STScI), and the NASA Exoplanet Science Institute (NExScI), respectively. Beginning with the class of 2018, the programs were merged into the NASA Hubble Fellowship Program and are now administered by STScI, in cooperation with CXC and NExScI.  Three leads, Dawn Gelino of NExScI, Paul Green of CXC, and myself, Andy Fruchter at STScI cooperatively guide the application and selection process, symposia, and science policies.

The Fellows Symposium

Until this academic year, the Einstein, Hubble, and Sagan programs have held separate symposia. This past October, however, we brought all the fellows together for a symposium which included the fellows from the first two classes of the NHFP as well as the final class of "Classic" Einstein, Hubble, and Sagan fellows. The meeting was held in Washington, DC adjacent to NASA Headquarters. In addition to visitors and speakers from NASA, the fellows brought in special guests to address environmental and social issues confronting astronomers, and to discuss career opportunities and challenges. However, it was the Fellows' talks that really stole the show. Nearly every area of astrophysics was discussed, from the first galaxies and fuzzy dark matter to observations of the closest star, our Sun, as a means to better understand radial velocity variation in extrasolar planetary systems.

In order to keep the length of the symposium to three days, we scheduled a mixture of plenary sessions and topical breakouts. However, the fellows decided that they did not want to miss any of the other talks. So this year, all talks at the NHFP Fellows Symposium will be plenary. The meeting will span the entire week of 21 September, and circumstances permitting, will be held in person at STScI in Baltimore, MD.
