An international team led by Professor Tian Hui from Peking University has recently measured the global magnetic field of the solar corona for the first time. The team used observations from the Coronal Multi-channel Polarimeter, an instrument designed by Dr. Steve Tomczyk at the National Center for Atmospheric Research, USA. Their results have been recently published in Science and Science China Technological Sciences. Yang Zihao, a first-year graduate student at Peking University, is the first author of both papers.
