Like previous discoveries, we ran simulations of the disk and found that a planet could re-create the observation.\u201d<\/p>\n<p>According to Terry, the models suggested a planet\u2019s presence, indicated by several images that strongly highlighted a particular region of the disk that turned out to have the characteristic sign of a planet \u2014 an unusual deviation in the velocity of the gas near the planet.<strong>&nbsp;<\/strong><\/p>\n<p>\u201cThis is an incredibly exciting proof of concept. We knew from our previous work that we could use machine learning to find known forming exoplanets,\u201d said Cassandra Hall, assistant professor of computational astrophysics and principal investigator of the Exoplanet and Planet Formation Research Group at UGA. \u201cNow, we know for sure that we can use it to make brand new discoveries.\u201d<\/p>\n<p>The discovery highlights how machine learning has the power to enhance scientists\u2019 work, utilizing artificial intelligence as an added tool to expand researchers\u2019 accuracy and more efficiently economize their time when engaged in such a vast endeavor as investigating deep, outer space.<\/p>\n<p>The models were able to detect a signal in data that people had already analyzed; they found something that previously had gone undetected.<\/p>\n<p>\u201cThis demonstrates that our models \u2014 and machine learning in general \u2014 have the ability to quickly and accurately identify important information that people can miss. This has the potential to dramatically speed up analysis and subsequent theoretical insights,\u201d Terry said. \u201cIt only took about an hour to analyze that entire catalog and find strong evidence for a new planet in a specific spot, so we think there will be an important place for these types of techniques as our datasets get even larger.\u201d&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A University of Georgia research team has confirmed evidence of a previously unknown planet outside of our solar system, and they used machine learning tools to detect it.
