How can you see the unseen? An Earth-sized telescope.
Today's reveal of the first-ever image of a black hole was achieved by the Event Horizon Telescope, a network of eight telescopes spanning the globe, led by Sheperd Doeleman of the Center for Astrophysics | Harvard & Smithsonian.
The black hole captured is at the center of Messier 87 (M87) in the Virgo galaxy cluster. That far from Earth, it's so small a target that no telescope in existence had the power to see it. Imagine trying to see an orange at the distance of the Moon.
Together, the eight telescopes create a new instrument capable of seeing something 55 million light-years away. And they all had to point at the black hole at exactly the same time.
@smithsonian_channel followed the team of international scientists on their quest toward this groundbreaking discovery, which you can see when "Black Hole Hunters" premieres Friday. #EHTBlackhole #RealBlackHole
