There is a supermassive compact object, named Sagittarius A*, in the center of the Milky Way. We have recently obtained the highest resolution images of this object with the Event Horizon Telescope, a global network of radio telescopes operating at high frequency of 230 GHz. In this talk I will discuss the challenges related to obtaining these images, their theoretical interpretation, as well as the question of how much confidence we have in Sagittarius A* being a Kerr black hole, following these new results.
