The Vera Rubin Observatory in Chile has officially launched its 10-year survey, marking the start of what Brian Stone, who fulfills the duties of the director of the U.S. National Science Foundation, describes as the “greatest cosmic movie ever made.” Equipped with a 3,200-megapixel camera, the observatory will repeatedly image the southern sky to track transient celestial events, supported by artificial intelligence to process the massive data influx.
How does the Vera Rubin Observatory capture the sky?
The observatory functions as a discovery engine. By utilizing a telescope with a camera the size of a passenger car, the facility captures the visible southern sky every few days. Phil Marshall of Stanford University reported to New Scientist that the telescope has already issued millions of alerts, signaling that after the test period, the Vera Rubin observatory is already operating as a real discovery machine. The telescope, commissioned a year ago, has already helped researchers discover more than 11,000 asteroids.
The observatory’s one of the most important tasks is to warn researchers if something changes in the sky: whether it is a previously unknown near-Earth asteroid moving between two images, or a supernova explosion occurring in a distant galaxy.
What is the goal of the 10-year LSST survey?
The primary objective of the program is to create the most comprehensive database of objects within our solar system. Researchers expect to monitor moving objects, map faint celestial bodies, and investigate the accelerated expansion of the universe caused by dark energy. By revisiting every point in the sky nearly 800 times over the 10-year LSST (Legacy Survey of Space and Time) survey, the telescope provides a “time-rich” dataset, as noted in a press release from the HUN-REN CSFK Konkoly Thege Miklós Astronomical Institute.
How are international researchers contributing?
Global collaboration is central to the project’s success, with Hungarian astronomers playing a notable role. Róbert Szabó, director of the HUN-REN CSFK Konkoly Thege Miklós Astronomical Institute, stated on Facebook that the program could fundamentally alter the understanding of the universe and 21st-century astrophysical research. Currently, 25 Hungarian researchers are working with the observatory’s data to study solar system objects, variable stars, supernovae, and cosmological phenomena.
