Published Research

Staff collaborations spanned the globe and the full breadth of astronomy.

Researchers, engineers, and technical staff continued to advance the field of astronomy through their published research in 2021, even as the coronavirus pandemic and its accompanying challenges stretched through a second year. More than 500 papers were co-authored with researchers from almost 60 countries, illustrating that astronomy is a global endeavor that endures even when in-person collaboration is curtailed. From studying ultra-faint dwarf galaxies alongside Korean colleagues, to exoplanet discoveries with collaborators in Morocco, STScI researchers continued to conduct exciting research with colleagues around the globe.
