Ever-changing Universe Revealed in First Imagery From NSF–DOE Vera C. Rubin Observatory (News Release - June 23)
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.
Rubin Observatory is a joint program of NSF NOIRLab and DOE’s SLAC National Accelerator Laboratory, who will cooperatively operate Rubin. NOIRLab is managed by the Association of Universities for Research in Astronomy
(AURA).
“Releasing our first scientific imagery marks an extraordinary milestone for NSF–DOE Rubin Observatory. It represents the culmination of about two decades of dedication, innovation and collaboration by a global team,” said Željko Ivezić, Director of Rubin Observatory Construction. “With construction now complete, we’re turning our eyes fully to the sky — not just to take images, but to begin a whole new era of discovery.”
The LSST Camera at the heart of Rubin Observatory captures extremely fine features in distant galaxies, stars and other celestial objects. A team of scientists, engineers and technicians at SLAC National Accelerator Laboratory designed and constructed the camera, which is roughly the size of a small car and weighs almost 6200 pounds
(2800 kilograms). Each image taken by the LSST Camera covers an area on the sky as big as 45 full Moons.
"Making the world’s largest digital camera will let scientists explore the cosmos in new ways, and at a scale that enables discoveries that should fundamentally change our understanding of the Universe,” said Aaron Roodman, Director of the LSST Camera and Deputy Director of NSF–DOE Rubin Construction from SLAC National Accelerator Laboratory. “Just as you would with the camera in your phone, it is finally time to point and shoot — our science begins now."
“I want to extend my gratitude to the brilliant and dedicated team of people who made this milestone possible,” said SLAC Director John Sarrao. “Rubin Observatory, and the LSST Camera at its heart, are unprecedented tools and a testament to the expertise, partnerships and leadership that drive discoveries forward, benefitting the nation and the world.”
During its ten-year survey, Rubin will generate approximately 20 terabytes of data per night, plus an additional 15 petabyte catalog database. In 10 years, Rubin data processing will generate around 500 petabytes, and the final dataset will contain billions of objects with trillions of measurements. With regular data releases, scientists will be able to conduct their own investigations into Rubin’s data remotely, enabling and expediting countless discoveries about our Universe and advancing science in ways that we can’t yet predict.
“We are so thrilled to share NSF–DOE Rubin Observatory’s first images with the world — it’s a proud moment for our whole team,” said Sandrine Thomas, Deputy Director of Rubin Construction and Associate Director of Rubin Observatory for Rubin Summit Operations, “While we still have a few important months of commissioning and testing ahead, everything we learn now brings us closer to full science operations later this year. Today is just the beginning!”
“It is not every day that a revolution stares you in the face, but that is precisely what the Rubin Observatory team — together with our colleagues at the NSF and DOE — has delivered with these first images. Astronomy is on the brink of transformation!” said Matt Mountain, AURA President. AURA is the managing organization for the Rubin Construction project and NSF NOIRLab. “Congratulations to the entire team for mastering the complexity of a fully active telescope and a pioneering optical system — imaging vast swaths of the sky with extraordinary precision with the world’s largest astronomical camera, and streaming data into an audacious real-time processing system. Everyone at AURA is proud to be part of this landmark moment — and the incredible science that now lies just ahead.”
