Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose 20 kton liquid scintillator detector being constructed in southern China. Its primary goal is the determination of the neutrino mass ordering using neutrinos emitted from the Taishan and Yangjiang nuclear power plants about 52.5 km away and neutrinos produced in the atmosphere, which will play a complementary role. In addition, oscillation parameters \(\Delta m^2_{31}\), \(\Delta m^2_{21}\), and \(\theta_{12}\) can be measured to a sub-percent level using the reactor neutrinos. Due to its large detector mass, JUNO can also provide a high statistics measurement on geo-neutrinos. This talk presents the current status of JUNO, as well as the physics potentials of measuring neutrinos from the reactors, atmosphere and Earth.
