Ready, Set, Process: Preparing for Rubin Observatory’s Data Deluge

In astrophysics, data are a precious commodity. They are scientists’ raw material, their starting point, their playground. Here, data begin with images of the sky, of distant galaxies, of stars in motion. From each image, scientists extract a trove of information such as brightness, position, velocity, and color. The principle is simple: The more sky you observe, and the more often you observe it, the greater your chances of catching the Universe’s rarest and most fleeting phenomena.

In late 2025, the NSF–DOE Vera C. Rubin Observatory, equipped with the world’s largest digital camera built at the DOE’s SLAC National Accelerator Laboratory, will begin the Legacy Survey of Space and Time (LSST). It will be the widest, fastest, and deepest sky survey ever made. Every night, the camera will scan the sky with clockwork precision, capturing a new 3,200-megapixel image every 40 seconds, each one 8 gigabytes. Every three nights, the telescope will revisit the same region of the sky, constructing a time lapse of the cosmos that will unfold over a decade.

NSF–DOE Vera C. Rubin Observatory is jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy’s Office of Science (DOE/SC). Rubin Observatory is a joint Program of NSF NOIRLab and DOE’s SLAC National Accelerator Laboratory, who will cooperatively operate Rubin.
