The images of the supermassive black holes Sgr A* and M87* by the Event Horizon Telescope (EHT) collaboration mark a special milestone in the history of the subject. For the first time we are able to see the shadow of black holes, testing basic predictions of the theory of general relativity. We are also now learning more about the fundamental astr...

... enough high-resolution spectroscopy of gas and stars in the centers of nearby galaxies revealed the presence of dark compact objects there ( Kormendy and Richstone 1995), including our own Galaxy ( Genzel and Townes 1987). Radio astronomers ( Balick and Brown 1974;Ekers et al. 1975) also found a compact flat spectrum radio source in the Galactic Center (Figure 3) not unlike radio cores seen in quasars, but much weaker. It was later called Sagittarius A* (Sgr A*) 6 . ...
