Scientists from the Slac (Stanford Linear Accelerator Center) National Accelerator Laboratory – one of the 17 national laboratories of the United States Department of Energy – have finally tested the camera of the future Vera C. Rubiin Observatory, The Large Synoptic Survey Telescope (LSST): the incredible resolution reached is 3200 Megapixel. The 3.2 billion pixels are made with an extraordinary array of 189 individual sensors, or charge-coupled devices (CCDs), each with a resolution of 16 megapixels, about the same as the imaging sensors of most modern digital cameras.
One such test was to take the first 3200 megapixel images of a variety of objects, including a Romanesco broccoli, chosen for its highly detailed surface texture.
The resulting images are so large that 378 ultra-high-definition 4K TV screens would be required to display just one full-size, and their resolution is so high that you could see a golf ball from about 15 miles away.
