We present the first image of the Galactic Center black hole, Sagittarius A*. Identified nearly 50 years ago as the nearest supermassive black hole candidate and among the most studied astrophysical objects, Sgr A* is the ultimate laboratory for black hole astrophysics. In six papers, the Event Horizon Telescope Collaboration presents observations, images, and analysis that spark new insights into accretion, outflow, and gravitational physics on scales not accessible through any other observation. These results are the culmination of a multi-year effort by the EHTC and a decades-long journey by the astronomy community to approach the event horizon through high-resolution imaging.
