From distant stars and galaxies to asteroids whizzing through the solar system, this next-generation facility unveils its first imagery and brings the night sky to life like never before

The NSF-DOE Vera C. Rubin Observatory, a major new scientific facility jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science, released its first imagery today at an event in Washington, D.C. The imagery shows cosmic phenomena captured at an unprecedented scale. In just over 10 hours of test observations, NSF-DOE Rubin Observatory has already captured millions of galaxies and Milky Way stars and thousands of asteroids. The imagery is a small preview of Rubin Observatory's upcoming 10-year scientific mission to explore and understand some of the universe's biggest mysteries.
"The NSF-DOE Vera C. Rubin Observatory demonstrates that the United States remains at the forefront of international basic science and highlights the remarkable achievements we get when the many parts of the national research enterprise work together," said Michael Kratsios, director of the White House Office of Science and Technology Policy. "The Rubin Observatory is an investment in our future, which will lay down a cornerstone of knowledge today on which our children will proudly build tomorrow."
"NSF-DOE Rubin Observatory will capture more information about our universe than all optical telescopes throughout history combined," said Brian Stone, performing the duties of the NSF director. "Through this remarkable scientific facility, we will explore many cosmic mysteries, including the dark matter and dark energy that permeate the universe."
"We’re entering a golden age of American science," said Harriet Kung, acting director of DOE's Office of Science. "NSF-DOE Rubin Observatory reflects what’s possible when the federal government backs world-class engineers and scientists with the tools to lead. This facility will drive discovery, inspire future innovators and unleash American excellence through scientific leadership."
The result of more than two decades of work, Rubin Observatory is perched at the summit of Cerro Pachón in Chile, where dry air and dark skies provide one of the world's best observing locations. Rubin's innovative 8.4-meter telescope has the largest digital camera ever built, which feeds a powerful data processing system. Later in 2025, Rubin will begin its primary mission, the Legacy Survey of Space and Time, in which it will ceaselessly scan the sky nightly for 10 years to precisely capture every visible change.
The result will be an ultrawide, ultra-high-definition time-lapse record of the universe. It will bring the sky to life with a treasure trove of billions of scientific discoveries. The images will reveal asteroids and comets, pulsating stars, supernova explosions, far-off galaxies and perhaps cosmic phenomena that no one has seen before.
Rubin Observatory is named in honor of trailblazing U.S. astronomer Vera C. Rubin, who found conclusive evidence of vast quantities of invisible material known as dark matter. Understanding the nature of dark matter, dark energy and other large-scale cosmic mysteries is a central focus of Rubin Observatory's mission. Dark energy is what scientists call the mysterious and colossally powerful force that appears to be causing galaxies in the universe to move away from each other at an accelerating rate. Although dark matter and dark energy collectively comprise 95% of the universe, their properties remain unknown.
Rubin Observatory will also be the most efficient and effective solar system discovery machine ever built. Rubin will take about a thousand images of the Southern Hemisphere sky every night, allowing it to cover the entire visible Southern sky every three to four nights. In doing so, it will find millions of unseen asteroids, comets and interstellar objects. Rubin will be a game changer for planetary defense by spotting far more asteroids than ever before, potentially identifying some that might impact the Earth or moon.
The amount of data gathered by Rubin Observatory in its first year alone will be greater than that collected by all other optical observatories combined. This treasure trove of data will help scientists make countless discoveries about the universe and will serve as an incomparable resource for scientific exploration for decades to come.
