Rubin Observatory Launches 10-Year LSST to Map Southern Sky Every Few Nights

Early in 2026, the Vera C. Rubin Observatory formally began its 10-year Legacy Survey of Space and Time, repeatedly imaging the entire visible southern sky in high detail.
Every few nights, the survey will sweep the sky to build an unprecedented time-lapse of the universe and, over time, a 3D map of the cosmos.
In a single year, Rubin is expected to collect more optical data than any telescope in history, extending its reach across nearly every area of astronomy.
During commissioning, the observatory already captured interstellar visitor Comet 3I/ATLAS and detected thousands of new near-Earth asteroids, underscoring its real-time discovery role.
That data haul is expected to sharpen research on galaxy formation and the universe's expansion over the coming decade.
