The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator experiment under construction in South China, at Kaiping, Jiangmen, Guandong province. Its primary physics goals are the determination of the neutrino mass ordering and the precise determination of the neutrino oscillation parameters by means of the accurate measurement of the oscillated spectrum of antineutrinos emitted by two reactor complexes, Taishan and Yangjiang, located at 53 km distance from the experiment. Given its dimensions and anticipated performance, JUNO has a very rich physics program which includes the study of neutrinos from the Sun, the Earth, the Galaxy, and eventually from Supernovae, and will give important contributions to the study of new physics processes. The JUNO collaboration plans to finish the detector construction by the end of 2023. In this paper I review the detector progress and the updated sensitivities on the main physics channels.
