WASHINGTON—Scientists are expected to unveil on April 10, the first-ever photograph of a black hole, a breakthrough in astrophysics providing insight into celestial monsters with gravitational fields so intense no matter or light can escape.
The U.S. National Science Foundation has scheduled a news conference in Washington to announce a “groundbreaking result from the Event Horizon Telescope (EHT) project,” an international partnership formed in 2012 to try to directly observe the immediate environment of a black hole.
