Chinese researchers discuss the imaging methods of the image of a black hole in Shanghai Astronomical Observatory (SAO), in east China's Shanghai, April 9, 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.

　　北京时间4月10日晚9时许，包括中国在内，全球多地天文学家同步公布首张黑洞真容。这一由200多名科研人员历时10余年、从四大洲8个观测点“捕获”的视觉证据，有望证实爱因斯坦广义相对论在极端条件下仍然成立。
