Abstract: Neutrinos are elusive particles with unique properties that offer key insights into the fundamental structure of matter and the cosmic sources that produce them. The Jiangmen Underground Neutrino Observatory (JUNO) is a next-generation, 20-kiloton liquid scintillator detector, the largest of its kind in the world, located in China and recently brought into operation after more than a decade of design and construction. In this talk, I will review the initial detector performance and present the first results from the experiment, based on about 60 days of data, which provide world-leading estimates of two neutrino oscillation parameters. I will also briefly outline the broader physics program enabled by JUNO and the additional measurements it aims to pursue.
