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.
Every three nights, the telescope will image the entire visible sky, producing thousands of pictures that will let astronomers see anything that moves or changes brightness. The expectation is that in this way, Vera Rubin will discover about 17 billion stars and 20 billion galaxies that we’ve never seen before — and that’s only the beginning.
“There’s so much that Rubin will do,” says Clare Higgs, the observatory’s astronomy outreach specialist. “We’re exploring the sky in a way that we haven’t before, giving us the ability to answer questions we haven’t even thought to ask.”
