The first image of the black hole in the center of our own galaxy by the Event Horizon Telescope collaboration marks a major milestone in our understanding of this well-studied source. It provides crucial confirmation of the Noble-prize-winning observation of stellar orbits around an unseen dark gravitating mass. The presence of a shadow surrounded by a ring-like morphology provides the most direct evidence that the central mass is consistent with the predictions of a black hole as described by Einstein’s General Relativity theory. I will describe the work behind and beyond the image, describe what it took to accomplish this milestone, and relate it to the first black hole image in M87*.
