Rubin Observatory\u2019s <a href=\"https:\/\/rubinobservatory.org\/news\/first-alerts\" rel=\"nofollow noopener\" target=\"_blank\">automated alert system<\/a> is online and already bombarding astronomers with things to look at in the night sky. The system went live publicly on Tuesday, February 24th, and on the first night dropped some <a href=\"https:\/\/www.scientificamerican.com\/article\/rubin-observatory-has-started-paging-astronomers-800-000-times-a-night\/\" rel=\"nofollow noopener\" target=\"_blank\">800,000 alerts<\/a> about <a href=\"https:\/\/www.theverge.com\/2022\/11\/4\/23440455\/near-earth-objects-potentially-hazardous-search-city-killers\" rel=\"nofollow noopener\" target=\"_blank\">asteroids<\/a>, supernovas, and feasting black holes. And that number is only expected to climb to the multiple millions per night.<\/p>\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1ymtmqpi _17nnmdy1 _17nnmdy0 _1xwtict1\">The observatory released the <a href=\"https:\/\/www.theverge.com\/news\/690924\/a-car-sized-camera-captures-the-cosmos\" rel=\"nofollow noopener\" target=\"_blank\">first images<\/a> taken with its car-sized Legacy Survey of Space and Time (LSST) camera in June of last year. But researchers and stargazers have been eagerly anticipating the launch of this system. Every night, the camera captures about 1,000 images and then compares those against a reference image taken when the telescope first went online. Differences are automatically flagged, and an algorithm can distinguish between potential supernovas and approaching asteroids to send alerts to interested parties, all in just a matter of minutes. This means scientists can quickly turn their attention to fleeting celestial events.<\/p>\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1ymtmqpi _17nnmdy1 _17nnmdy0 _1xwtict1\">Thankfully, the alerts aren\u2019t all-or-nothing. They can be <a href=\"https:\/\/rubinobservatory.org\/for-scientists\/data-products\/alerts-and-brokers\" rel=\"nofollow noopener\" target=\"_blank\">filtered<\/a> by event type, brightness, or even the number of events within a given time period. That should help keep researchers from becoming overwhelmed by alerts as the Rubin Observatory ramps up the rate of discoveries.<\/p>\n","protected":false},"excerpt":{"rendered":"The Vera C.
