Rubin Observatory Begins Ten-Year Sky Survey

The NSF-DOE Vera C. Rubin Observatory has started its ten-year Legacy Survey of Space and Time, beginning a systematic, high-cadence imaging campaign of the southern sky. With a 3,200-megapixel camera producing roughly 10 terabytes of image data per night and up to 100 revisits per year, Rubin will catalog about 17 billion stars, 20 billion galaxies and millions of asteroids. The survey aims to study dark matter, dark energy and transient astrophysical phenomena.
