Black hole, the most mysterious and crazy celestial body.
Approaching him and exploring him, can we solve the mystery of the ultimate destiny of the universe?

This is the first stellar black hole discovered by human beings, and also the only X-ray binary star system with a mass of more than 20 times the mass of the sun and rotation close to the speed of light discovered and confirmed by human beings so far. This discovery is helpful for further research The space-time characteristics and evolution history of black hole are studied.
Tencent News and Gaoshan University jointly create a series of live broadcast of “25 ° C science”.
