On May 12, 2022, an international team of astronomers led by scientists at the Harvard—Smithsonian Center for Astrophysics revealed the first image of a supermassive black hole at the center of the Milky Way. Researchers have known about the black hole, called Sagittarius A*, or Sgr A* (pronounced sadge-ay-star), since the 1970s. However, until now, its existence had only been deduced from its effect on surrounding stars and dust. The stunning picture is the first direct visual evidence of our galaxy's black hole.
