NSF-DOE Vera C. Rubin Observatory on Cerro Pachón in Chile is a next-generation survey facility built around the 8.4-meter Simonyi Survey Telescope and the 3.2-gigapixel LSST Camera. It transitioned from construction to operations in October 2025, and its 10-year Legacy Survey of Space and Time began in June 2026, capturing southern-sky images and streaming alerts. Public visits are currently offered by reservation through the official visitor program; availability fills quickly, and conditions can change at this active research facility.
