The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino detector under construction in China with a 20 kton liquid scintillator neutrino target and an energy resolution of 3% at 1 MeV. By studying the disappearance of electron antineutrinos emitted from 8 nuclear reactors at a baseline of about 52.5 km, JUNO will determine the neutrino mass ordering to 3σ significance within about 6 years of running and will measure 3 neutrino oscillation parameters to sub-percent precision. JUNO will also have a rich program with neutrinos from a variety of natural sources, such as the Earth, the Sun, the Atmosphere, and supernova explosions, and will deploy a satellite detector called JUNO-TAO that will measure the energy spectrum of reactor antineutrinos with unprecedented energy resolution. Construction of the detector is well underway and is expected to be completed this year. This talk will cover the design and status of the experiment, as well as its physics prospects.
