When the Vera C. Rubin Observatory comes online in 2025, it will be one of the most powerful tools available to astronomers, capturing huge portions of the sky every night with its 8.4-meter mirror and 3.2-gigapixel camera. Each image will be analyzed within 60 seconds, alerting astronomers to transient events like supernovae. An incredible five petabytes (5,000 terabytes) of new raw images will be recorded each year and made available for astronomers to study.

Not surprisingly, astronomers can’t wait to get their hands on the high-resolution data. A new paper outlines how the huge amounts of data will be processed, organized, and disseminated. The entire process will require several facilities on three continents over the course of the projected ten-year-long survey.
