Major Telescope Hosts World's Largest Digital Camera

The Vera C. Rubin Observatory in Chile will begin full operations in the coming months with the world's largest digital camera, capturing 3,200-megapixel images that would require several hundred HD television screens to display at full resolution. The $810 million facility will map the entire southern sky every three to four nights, observing each location approximately 800 times over its planned decade of operations.

The telescope's unusual design allows it to photograph an area equivalent to 45 full moons in each shot and swing between different sky locations every 40 seconds. Its digital camera, roughly the size of a small car, will generate eight million alerts per night when it detects astronomical objects that move or change brightness, according to Tony Tyson, the University of California, Davis astronomer who conceived the project in the 1990s. Astrophysicist Federica Bianco, who received a preview of the telescope's first full-color image, described her reaction simply: 'There are so many stars!' The team plans to unveil that inaugural image on June 23.
