Perched atop the Cerro Pachón mountain in Chile, 8,684 ft excessive within the Atacama Desert, the place the dry air creates a number of the finest circumstances on the planet to view the evening sky, a brand new telescope in contrast to something constructed earlier than has begun its survey of the cosmos. The Vera C. Rubin Observatory, named for the astronomer who found proof of darkish matter in 1978, is predicted to disclose some 20 billion galaxies, 17 billion stars within the Milky Manner, 10 million supernovas, and thousands and thousands of smaller objects inside the photo voltaic system.
“We’re absolutely guaranteed to find something that blows people’s minds,” says Anthony Tyson, chief scientist of the Rubin Observatory. “Something that we cannot tell you, because we don’t know it. Something unusual.”
This large astronomical haul will come from the observatory’s 10-year Legacy Survey of House and Time, which is slated to start later this yr. The primary science photographs from the telescope have been launched to the general public at this time.
Rubin’s unprecedented survey of the evening sky guarantees to remodel our understanding of the cosmos. What occurred in the course of the early phases of planet formation within the photo voltaic system? What sorts of unique, high-energy explosions happen within the universe? And the way does the esoteric drive that scientists name darkish vitality really work?
“Usually you would design a telescope or a project to go and answer one of these questions,” says Mario Juric, the information administration venture scientist for Rubin. “What makes Rubin so powerful is that we can build one machine that supplies data to the entire community to solve all of these questions at once.”
The telescope will create a decade-long, high-resolution film of the universe. It’s going to generate about 20 terabytes of knowledge per day, the equal of three years streaming Netflix, piling up some 60,000 terabytes by the top of its survey. In its first yr alone, Rubin will compile extra information than all earlier optical observatories mixed.
“You have to have an almost fully automated software suite behind it, because no human can process or even look at these images,” Juric says. “The vast majority of pixels that Rubin is going to collect from the sky will never ever be seen by human eyes, so we have to build software eyes to go through all these images and identify … the most unusual objects.”
These uncommon objects—asteroids from different photo voltaic methods, supermassive black holes devouring stars, high-energy blasts with no recognized supply—comprise secrets and techniques in regards to the workings of the cosmos.
“You build a telescope like this, and it’s the equivalent of building four or five telescopes for specific areas,” Juric says. “But you can do it all at once.”

A Telescope Like No Different
Housed in a 10-story constructing, the Rubin Observatory is supplied with an 8.4-meter main mirror and a 3,200-megapixel digital digicam, the biggest ever constructed. The telescope rotates on a specialised mount, taking 30-second exposures of the sky earlier than rapidly pivoting to a brand new place. Rubin will take about 1,000 photographs each evening, photographing all the Southern Hemisphere sky in extraordinary element each three to 4 days.
“It’s an amazing piece of engineering,” says Sandrine Thomas, a venture scientist who works on the optical devices of the Rubin Observatory.
