Unveiling the World' 's Largest Digital Camera
Officials from the U.S.-funded project shared with AFP that this $800 million camera will capture 3,200-megapixel photos, an astronomical leap from existing technology.
To put it in perspective, one image would require more than 300 average-size high-definition televisions lined up together. The camera's groundbreaking capacity will allow it to sweep the sky every three days, opening new frontiers for scientists.
Stuartt Corder, deputy director of NOIRLab, the US research center overseeing the observatory, boldly predicts a "paradigm shift in astronomy" with this venture.
Bruno Dias, president of the Chilean Society of Astronomy, explains that researchers will transition from "studying one star and knowing everything in-depth about that one star to studying thousands of stars at a time."

Chile's Role in Astronomy
The Rubin Observatory camera solidifies Chile's place in astronomical observation, home to a third of the globe's most powerful telescopes. Nestled 2,500 meters up the Cerro Pachon mountain, the observatory benefits from the region's clear skies, making it an ideal hub for studying the universe.
Chile's telescopic journey has come a long way since the installation of the 40-centimeter Cerro Tololo telescope in the 1960s, carried on the back of a mule due to the lack of roads.
Now, with the Vera C. Rubin Observatory joining the ranks, Chile is poised to maintain its status as the astronomy capital of the world.
The Camera's Main Mission
The Rubin Observatory's primary task is the Legacy Survey of Space and Time (LSST), a 10-year endeavor to capture images of 20 million galaxies, 17 billion stars, and six million space objects.
This comprehensive survey promises to provide an up-to-date inventory of the solar system, map our Milky Way galaxy, and delve into the mysteries of energy and dark matter.
Beyond its image-capturing capabilities, the Rubin Observatory is key to unraveling the secrets of galaxy clusters through intracluster light. This faint glow, 1000 times fainter than the darkest night sky, is a cosmic storyteller, revealing the evolution of galaxy clusters over billions of years.
Mireia Montes, a researcher at Instituto de Astrofísica de Canarias, notes,"the power of Rubin is that it's going to provide us with lots of clusters of galaxies that we can explore."
The observatory's 10-year survey will take millions of high-resolution images, enabling scientists to analyze intracluster light across the Universe and gain insights into the distribution of dark matter.
The Vera C. Rubin Observatory, named in honor of the US astronomer who discovered dark matter, joins a constellation of space observation centers in northern Chile. The region's desert landscape, nestled between the Pacific Ocean and the Andes mountain range, creates the clearest skies on the planet, making it an astronomical haven.
