‘After a decade of construction, a large new reflecting telescope publicly released its first images on Monday, and they are nothing short of spectacular.

The Vera C. Rubin Observatory’s primary mirror is 8.4 meters in diameter, which makes it one of the largest optical telescopes in the world. However, the real secret sauce of the telescope is its camera—the automobile-sized Legacy Survey of Space and Time camera—which has a resolution of 3,200 megapixels. Which is rather a lot.

The observatory is on a remote 2,682-meter-high (8,799 ft) mountain in northern Chile, a region of the planet with some of the best atmospheric “seeing” conditions.

The main goal of the telescope is to scan the entire Southern Hemisphere sky by taking 1,000 high-definition photographs every three nights for the next 10 years. The idea is that, assembled end to end, the observatory will provide a high-definition, four-dimensional film of the Universe changing over a decade. It will seek to encompass everything from nearby asteroids and comets to distant supernovae.…’ Eric Berger via Ars Technica
