Summary
Rubin Observatory has officially begun the 10-year Legacy Survey of Space and Time after completing system optimization, readiness reviews and scientific validation.
Every 40 seconds, the Simonyi Survey Telescope’s 3,200-megapixel camera captures a new image as Rubin scans the entire southern sky every few nights for a decade.
Each night, the observatory will gather about 10 terabytes of data and issue as many as 7 million alerts on changing objects, feeding automated brokers for rapid follow-up.
Early optimization runs already found more than 11,000 new asteroids—including 33 near-Earth objects and 380 Trans-Neptunian objects—highlighting Rubin’s reach beyond distant-universe science.
By revisiting each sky position about 800 times, LSST aims to build a time-lapse record containing billions of objects and trillions of measurements for broad public and scientific use.
What could a telescope taking a new sky image every 40 seconds discover that astronomers have never even imagined?
After finding 11,000 unknown asteroids before full operations, how much could Rubin reshape what we know about the solar system?
Rubin will issue seven million nightly sky alerts—but can scientists keep up with the flood of cosmic surprises?

Overview
The Vera C. Rubin Observatory began the Legacy Survey of Space and Time (LSST) in June 2026, using its powerful 3.2-gigapixel camera and 8.4-meter telescope to scan the southern sky and generate massive amounts of data each night. To handle this data, scientists developed GPU-accelerated workflows like ASTIA, which process images in milliseconds and enable real-time public alerts for millions of cosmic events. These alerts are sorted by machine learning brokers, allowing researchers worldwide to quickly respond to discoveries. The observatory’s open data policy ensures that anyone can access the full dataset, making cutting-edge astronomy accessible to all and setting the stage for future space missions.
