Humankind caught its first glimpse of a black hole on April 10, 2019. The Event Horizon Telescope (EHT) team, which uses an Earth-spanning network of radio observatories acting in concert, shared images it had captured of an apparent black hole with 6.5 billion times the mass of our sun in the center of the nearby M87 galaxy. This was a breathtaking achievement—our first view of one of the most mysterious objects in the universe, long predicted but never directly “seen.” Even more exciting, the images, and the observations that should follow, are beginning to provide new clues about one of the deepest puzzles in physics.
