First image of black hole released in Shanghai along with other cities worldwide

The first-ever image of a supermassive black hole at the heart of the distant galaxy M87 is released during a press conference held by Shanghai Astronomical Observatory (SAO), in east China's Shanghai, April 10, 2019. The image of the black hole, based on observations through the Event Horizon Telescope (EHT), a planet-scale array of eight ground-based radio telescopes forged through international collaboration, was unveiled in coordinated press conferences across the globe at around 9:00 p.m. (Beijing time) on Wednesday. The landmark result offers scientists a new way to study the most extreme objects in the universe predicted by Albert Einstein's general relativity. (Xinhua/Jin Liwang)
