Vera C. Rubin Observatory
Watch the LSSTCam field-of-view raster-scan a patch of sky, cataloging stars, galaxies, and transient events in real-time. Inspired by Rubin Observatory’s formal 10-year Legacy Survey of Space and Time, underway since early 2026 — in a single year it will gather more optical data than any telescope in history.

The science: The Vera C. Rubin Observatory in Chile houses an 8.4-meter mirror and the world’s largest digital camera (3.2 gigapixels). Each 30-second exposure captures a 9.6 square-degree field — 40× the area of the full Moon. Over 10 years the LSST will image the entire southern sky ~1,000 times each, generating ~15 TB of data per night and issuing ~37 million transient alerts every night to astronomers worldwide.
