The EHT Collaboration unveiled the first direct visual evidence of the supermassive black hole in the center of the elliptical galaxy Messier 87 and its shadow. The shadow of a black hole seen here is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary -- the event horizon from which the EHT takes its name -- is around 2.5 times smaller than the shadow it casts and measures just under 25 billion miles (40 billion km) across.
