LSST Camera’s Unintentional World Records
Jun 28, 2022
In an unassuming tan building, past windswept hills and equipment from the now-defunct B-Factory particle accelerator, scientists and engineers at the SLAC National Accelerator Laboratory (SLAC) have nearly finished building the world’s largest digital camera for the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST). Construction began in 2015 and since then, the LSST camera team set a Guinness World Record for the camera’s focal plane, a table-sized array of 189 sensors working in concert to produce the highest resolution digital image ever made: 3,200 megapixels. That’s over 1500 times the resolution of a high-definition television. The team didn’t plan on breaking any world records, but to build a camera that can take thousands of images every night—each one over three billion pixels in size—they sort of had to.
