Space-based telescope begins duty

X-ray observatory will aid research into black holes and neutron stars

China's first space-based X-ray observatory, the Hard X-ray Modulation Telescope, initiated formal operations on Tuesday after more than seven months of an in-orbit trial run.

Results of the trial run show that the satellite's devices work well and its capabilities are good. During the period, it played an important role in global efforts to help learn more about gravitational waves, according to a statement published by the China National Space Administration.
