Rubin Observatory begins shooting the greatest cosmic movie ever, beginning a new era of astronomy
The universe is ready for its close-up! That’s because today marks the day that the Vera C. Rubin Observatory begins it’s 10-year mission to shoot the greatest cosmic move ever created.
The decade-long project officially known as the Legacy Survey of Space and Time (LSST) is set to revolutionize our view of the universe. That means June 30, 2026 marks the beginning of a new era for astronomy.
“Today, we begin filming the greatest cosmic movie ever made,” U.S. National Science Foundation (NSF) director Brian Stone said in a statement. “Every night, NSF–Department of Energy (DOE) Rubin Observatory will expand the frontiers of knowledge and strengthen America’s global leadership in science and innovation.”
The LSST will see Rubin use its 3200-megapixel camera, the largest digital camera ever created, to repeatedly scan the entire sky over the southern hemisphere every few nights. Over the next decade, each point in the sky will be covered 800 times; this will result in an ultra-wide, ultra-high-definition time-lapse record of the cosmos, the scale of which will put any Sci-Fi epic to shame.
And that includes the daring voyage of discovery present in any great Sci-Fi story. Astronomers teaming with Rubin will dive headfirst into the dark universe. That means the dual mysteries of dark energy — the force driving the accelerating expansion of the universe — and dark matter — which secretly seems to be holding galaxies together. Both are invisible to us, yet integral to the universe.
“With the launch of the ten-year Legacy Survey of Space and Time, NSF–DOE Rubin Observatory is opening a new window on the universe. It is embarking on a mission that will redefine modern cosmology and astrophysics,” Darío Gil, Under Secretary for Science at the DOE said in the statement. “With its world-class design and tools, Rubin Observatory will capture the dynamic nature of our cosmos and reveal unimagined insights into our universe’s biggest mysteries, from our own solar system to the very structure of the universe.
“By seeking to understand the enigmatic phenomena of dark energy and dark matter, we are not just observing the stars; we are striving to grasp the fundamental laws that govern our existence.”
The main actors in this LSST production will be a cast of pulsating stars, supernova explosions and fossil records of galaxies. This will not only provide clues as to the nature of dark matter and dark energy, but could also reveal hitherto undiscovered cosmic phenomena.
Rubin will also make an impact on astronomy within the solar system, not just at the vast cosmic distances.
For instance, Rubin is expected to discover millions of new asteroids and comets in our cosmic backyard, becoming the most powerful solar system discovery machine ever created. It is already living up to this potential.
In its first few months of operations, Rubin, which sits atop a mountain in northern Chile, has already discovered 11,000 never-before-seen asteroids, including 33 near-Earth objects and 380 icy minor planets and dwarf planets out past the orbit of Neptune, referred to as trans-Neptunian objects.
It is estimated that the final LSST dataset will contain billions of objects, and its results will be available to all scientists and the general public — truly sparking a new age of cosmic discovery.
“It’s taken 20 years of hard science, engineering, and more to get to the point where we can call ‘action’ as we start rolling on this blockbuster movie of the universe,” Phil Marshall, Deputy Director of Rubin Operations for SLAC, said. “Millions of alerts in just the last couple of months show that Rubin is up and running as a discovery machine. Now we’re putting it all together.”
