The M87 image made some astronomers famous recently as the first image of a black hole.
In the Milky Way, it has been concluded that there must be a black hole due to the movement of stars near the center. But why is there no such light effect in our black hole, as there is in M87? Or is it there, but we cannot see it for some reason?
Although we cannot see the event horizon itself, because it cannot emit light, glowing gas orbiting around the black hole reveals a telltale signature: a dark central region (called a “shadow”) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun. The image of the Sgr A* black hole is an average of the different images the EHT Collaboration has extracted from its 2017 observations.
