>On a mountaintop in northern Chile, the world’s largest digital camera is preparing to power up. >Its mission is simple yet ambitious — to photograph the entire night sky in extreme detail and unlock some of the universe’s deepest secrets. >Housed inside the Vera C. Rubin Observatory — a new telescope nearing completion on Cerro Pachón, a 2,682-meter (8,800-feet) tall mountain about 300 miles (482 kilometers) north of the Chilean capital Santiago — the camera has a resolution of 3,200 megapixels, roughly the same number of pixels as 300 cell phones, and each image will cover an area of sky as big as 40 full moons. . .
