Rubin Observatory Begins 10-Year Sky Survey Set to Transform Astronomy

The Vera C. Rubin Observatory, located in Chile, has officially commenced its decade-long "Legacy Survey of Space and Time" (LSST) scientific program, marking one of the most ambitious astronomical endeavors in history. This initiative promises to revolutionize our understanding of the universe by generating the most extensive and detailed map of the southern sky ever created.

Funded by the U.S. National Science Foundation and the Department of Energy, the observatory, inaugurated in June 2025, involves international collaboration. Notably, two prominent Serbian astronomical institutions, the Department of Astronomy at the University of Belgrade's Faculty of Mathematics and the Astronomical Observatory in Belgrade, are contributing to this groundbreaking project.

Over the next ten years, the Rubin Observatory will continuously observe and image the sky from its mountaintop location in Chile. Utilizing the world's largest digital camera, boasting 3,200 megapixels, it will capture a new image of the sky approximately every 40 seconds. This creates an unprecedented ultra-high-resolution, time-lapse view of the cosmos.

The LSST program aims to photograph every point in the southern hemisphere sky at least 800 times. The observatory is expected to collect about ten terabytes of data nightly, generating millions of alerts for newly discovered or variable celestial objects. This will enable astronomers worldwide to respond to significant astronomical events in near real-time. The project's goal is to map the universe's changes over time, tracking phenomena from supernova explosions and variable stars to asteroid movements and galactic evolution, potentially revealing previously unobserved cosmic occurrences. The observatory has already proven effective in discovering new objects in the solar system, identifying over 11,000 previously unknown asteroids, including near-Earth objects, during its initial operational phase.
