To tackle this, they developed the SNIascore algorithm.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;We knew that once we trained our computers to do this work, they would lift a great burden from us,&#8221; said Christopher Fremling, a California Institute of Technology employee and one of the project&#8217;s authors.<\/p>\n<\/blockquote>\n<p>Since 2017, ZTF has identified thousands of supernovae, which can be divided into two classes:<\/p>\n<ul class=\"wp-block-list\">\n<li>hydrogen-poor Type I;<\/li>\n<li>hydrogen-rich Type II.<\/li>\n<\/ul>\n<p>Type I supernovae most often arise due to accretion of matter from a neighboring donor star, which falls onto its surface and triggers a thermonuclear explosion. Type II forms when massive stars run out of the fuel needed for nuclear fusion and can no longer resist gravitational collapse.<\/p>\n<p>SNIascore classifies a special type of supernovae called Type Ia. They occur when a dying star explodes and form a homogeneous light output, known as &#8220;standard candles.&#8221; Astronomers use information about them to measure distances in the universe and determine the rate of expansion of the cosmos.<\/p>\n<p><iframe loading=\"lazy\" width=\"750\" height=\"422\" src=\"https:\/\/www.youtube.com\/embed\/2ZVdZeS1jAs\" title=\"Machine Learning Tools Automatically Classify 1,000 Supernovae\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>Each night, after finishing the search for transient events and objects in the sky with the help of ZTF, the AI begins classifying Type Ia supernovae.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;SNIascore found its first supernova in April 2021, and a year and a half later we reached a milestone of 1,000 objects,&#8221; said Fremling.<\/p>\n<\/blockquote>\n<p>According to him, the algorithm works virtually without error. In the future, scientists plan to deploy the same model with other observing facilities.<\/p>\n<p>Astronomers also intend to apply SNIascore to classify other types of supernovae.
