At 13:00 on April 10, 2019, UTC time, global astronomers, including China, announced the black hole “true”. The black hole is located in the center of a giant elliptical galaxy M87 in Virgo, 55 million light-years from Earth, and is about 6.5 billion times more massive than the Sun. Its core area has a shadow surrounded by a crescent moon. Einstein’s general theory of relativity proved to be true under extreme conditions.
