WASHINGTON — Scientists are sharing the first pictures to show the immediate surroundings of a supermassive black hole, captured by a network of radio telescopes that adds up to what could be considered the world’s widest observatory.
First results from the project, known as the Event Horizon Telescope, are being unveiled at 9 a.m. ET (6 a.m. PT) Wednesday during a global wave of briefings.
The National Science Foundation is providing streaming-video coverage of the big reveal here in Washington, at the National Press Club. Scientists in Europe and Japan are streaming separate briefings in Brussels and Tokyo. Still more news conferences are happening in Chile, China and Taiwan.
The Event Horizon Telescope, or EHT, is actually an consortium of radio telescope facilities that are combining efforts to do what none of them could do on ...
