An artist's concept shows the supermassive black hole at the center of the Milky Way galaxy, known as Sagittarius A*

NASA's Webb telescope observes violence around Milky Way's central black hole

While the events observed around Sgr A* are dramatic, this black hole is not as active as some at the center of other galaxies.
