Chinese researchers have studied the lunar samples brought back by the Chang'e-5 mission and dated the youngest rock on the Moon at around 2 billion years in age, extending the "life" of lunar volcanism 800-900 million years longer than previously known. The study, conducted mainly by a research team at the Institute of Geology and Geophysics (IGG), Chinese Academy of Sciences (CAS), was presented in three Nature papers and published online Tuesday.
