The NSF-DOE Vera C. Rubin Observatory has launched a real-time monitoring system for the night sky, which is expected to generate a large number of alerts. The system is described as a discovery machine that will capture vast amounts of data, with one report suggesting that hundreds of thousands of new objects were found in a single night. The launch marks the beginning of a new era of cosmic discovery, with the observatory's capabilities being likened to capturing a vast cosmic movie.
