The world’s largest astronomical digital camera was unveiled at the US Department of Energy’s Stanford Linear Accelerator (SLAC) National Accelerator Laboratory. The camera is 1.65 meters tall and has 3.2 billion pixels. Over the next decade, it will help scientists study billions of galaxies to better reveal the nature of dark matter. As part of the Legacy Survey of Space and Time (LSST) project, the camera, called the LSST Camera, will be installed at the Vera Cooper Rubin Observatory on top of Cerro Pazón, Chile by the end of 2024 , and to photograph and catalogue some 20 billion galaxies over the next decade. The LSST camera works like any other digital camera, but it’s much larger, with 189 sensors mounted on it that pick up light from objects such as stars and convert it into electrical signals that turn into digital images . Each sensor is about 16mm large and contains more pixels than an iPhone. Overall, the digital camera has 3.2 gigapixels and can take extremely high-resolution images— enough to see dust grains on the moon .
