Through its five Programs — Cerro Tololo, CSDC, Gemini Observatory, Kitt Peak and Vera C. Rubin Observatory — NSF’s NOIRLab serves as a focal point for community development of innovative scientific programs, exchange of ideas, and creative development. NOIRLab’s infrastructure enables the astronomy community to advance understanding of the Universe by exploring significant areas of astrophysics, including dark energy and dark matter, galaxies and quasars, the Milky Way, exoplanets, and small bodies in our own Solar System.
