Hard X-ray Modulation Telescope (HXMT) also known as Insight (Chinese: 慧眼) is a Chinese X-ray space observatory, launched on June 15, 2017 to observe black holes, neutron stars, active galactic nuclei and other phenomena based on their X-ray and gamma-ray emissions. It is based on the JianBing 3 imagery reconnaissance satellite series platform.
The project, a joint collaboration of the Ministry of Science and Technology of China, the Chinese Academy of Sciences, and Tsinghua University, has been under development since 2000.
