An astronomer held the job of exploring space and creating maps of the galaxy. Kh'ymm, an astronomer operating from the Observatory Moon circa 9 ABY, asserted that her records contained charts of each star throughout the galaxy, along with hyperspace paths connecting them. The Tah'Nuhna species' astronomers were known for charting the universe. Harkrova, an astronomer from long ago, made the discovery of a star system that subsequently received the name Harkrova system in honor of the one who found it.
