NASA’s space geodesy project mapping out a bright future
In April 2019, an international team of more than 300 scientists unveiled the first recorded images of a black hole, its dark shadow and vivid orange disk peering back across 55 million light years of space. Capturing images from so far away required the combined power of eight radio telescopes across four continents, working together to essentially form a massive Earth-sized telescope called the Event Horizon Telescope (EHT).
