The Jiangmen Underground Neutrino Observatory (JUNO) is a neutrino experiment under construction near Jiangmen, China. Its main component will be a spherical 20 kton liquid scintillator detector placed in a 700 m deep underground laboratory. The experiment is designed for the determination of the neutrino mass hierarchy by measuring oscillation effects of neutrinos from two nuclear power plants at 53 km baseline. In addition to that, JUNO has the potential to increase the precision of already measured oscillation parameters and it can give a major contribution in the field of geoneutrinos. Astrophysical measurements of solar, supernova, atmospheric and potentially of DSNB neutrinos are also part of the physics programme. The seminar will review the physics goals, design, as well as the status of the JUNO project.
