This image shows Vera C. Rubin Observatory, a Program of NSF’s NOIRLab, beneath a late-twilight sky. Rubin is being built to conduct the Legacy Survey of Space and Time (LSST). This survey will observe the entire visible southern sky every few nights over the course of a decade, capturing about 1000 images of the sky every night and giving us a new view of our evolving Universe. The LSST is set to probe four areas of science, one of which is mapping the Milky Way to answer questions about its structure and formation. Once Rubin Observatory comes online in 2025, scientists will be able to access the data taken every night of operation. Rubin Observatory is a joint initiative of the National Science Foundation and the Department of Energy (DOE). Once completed, Rubin will be operated jointly by NSF’s NOIRLab and DOE's SLAC National Accelerator Laboratory to carry out the Legacy Survey of Space and Time.
