Vera C. Rubin Observatory’s Legacy Survey of Space and time: nothing can hide 
in the sky

The Legacy Survey of Space and Time (LSST) of the Vera C. Rubin Observatory 
is one of the most ambitious ground-based astronomical programs of this 
decade. The revolutionary 8.2-meter Simonyi Survey Telescope, equipped with a 
3.2-gigapixel camera—the largest digital camera ever built for astronomy -- 
will conduct an unprecedented ten-year survey of the southern sky. Following 
a long preparatory phase, operations are about to begin. LSST will image the 
entire sky visible from Chile every three nights, detecting everything that 
moves or changes. Over a decade, it will effectively create a deep, 
multi-color time-lapse movie of the Universe. With this unique dataset, 
researchers will probe the nature of dark matter and dark energy; discover 
interstellar comets and potentially hazardous near-Earth asteroids; study 
supernovae and other astrophysical transients; and map the structure and 
evolution of the Milky Way. The observatory will issue public alerts within 
60 seconds of each observation, generating millions of alerts every night and 
ultimately producing hundreds of petabytes of data. What scientific and 
technological challenges arise from processing this enormous data volume and 
managing the nightly alert stream? What role do Hungarian researchers play in 
this global endeavor? And how will LSST reshape astronomy and astrophysics in 
the coming decades?
