Strongest magnetic field in universe directly detected by X-ray space observatory

The Insight-HXMT team has performed extensive observations of the accreting X-ray pulsar GRO J1008-57 and has discovered a magnetic field of ~1 billion Tesla on the surface of the neutron star. This is the strongest magnetic field conclusively detected in the universe. This work, published in the Astrophysical Journal, was primarily conducted by scientists from the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences and Eberhard Karls University of Tübingen, Germany.
