SLAC National Accelerator Laboratory scientists and engineers have completed work on the most powerful camera ever created.

The Legacy Survey of Space and Time camera (LSST) boasts an impressive 3,200-megapixel capacity and is approximately the size of a small car, weighing around 3,000 kg. The installation of these cameras in the newly constructed Vera C. Rubin Observatory building will allow scientists to capture incredibly detailed images of the Southern Hemisphere’s skies over the next decade.

Multiple organizations were involved in the production of the camera. Brookhaven National Laboratory contributed a digital sensor array, Lawrence Livermore National Laboratory designed and built the lenses, and the Institute of Particle and Nuclear Research at the National Center for Scientific Research in France played a role as well.

With the completion of SLAC’s LSST camera and its integration with Rubin Observatory systems in Chile, the project is on track to produce comprehensive night sky maps. University of Washington professor Željko Ivezic, the Rubin Observatory construction director, emphasized the significance of this achievement.

The new camera’s capabilities are immense, including photographing the entire visible sky every few nights, potentially discovering billions of stars and galaxies over the next decade. It would require hundreds of ultra-high-definition TV screens to display a single image at full resolution.

The camera’s detailed images of the Southern Hemisphere sky aim to fill gaps in previous space observations and provide insights into galaxy distribution, dark energy, dark matter, and other astronomical mysteries. By detecting weak gravitational lensing and studying the evolution of the universe, astronomers hope to gain valuable insights from this data.

Researchers believe the LSST camera could aid in the creation of more detailed maps of solar system objects and help identify near-Earth object threats. The installation of the camera at the Vera C. Rubin Observatory in Chile is expected to be completed soon.

Vera C. Rubin Observatory – the new home for cameras

Following the completion of the LSST camera, preparations are underway to transport it to the Vera C. Rubin Observatory atop a rugged Andean mountain pass. Its initial imaging is expected in early 2025, allowing the public to witness its capabilities by 2027.
