Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they have the answer. Thanks to a global array of radio telescopes that turn the Earth into a giant receiver, we've imaged one black hole (Messier 87) and may soon have the first picture of the event horizon of Sagittarius A*, the black hole at the center of the Milky Way galaxy.
