The Division’s scientific breadth and expertise provide the Agency with a unique interdisciplinary workforce utilizing multidisciplinary teams of astronomers, astrophysicists, chemists, microbiologists, physicists, and planetary scientists and are organized into three branches which correspond to the following core science areas:
Astrophysics Branch (Code STA)
Researchers study the physical and chemical properties of astronomical objects and phenomena by observing their radiation at optical, infrared and ultraviolet wavelengths.
Planetary Systems Branch (Code STT)
Researchers develop new, fundamental knowledge about the origins of stars and planetary systems, their evolution and formation, their environment, and astrobiology.
Exobiology Branch (Code STX)
Researchers study the history, distribution, and chemistry of biogenic elements in the solar system; prebiotic chemical evolution and the origin of life; and the history of Earth’s early biosphere as recorded in microorganisms and ancient rocks.
