The picture shows an image of milky way at the location of Sagittarius A*. In the year 2008, the teams of Andra Ghez and Reinhard Genzel provided the best empirical evidence that a supermassive black hole exists in the center of our galaxy by observing the orbits of certain stars around it. For this discovery Andrea Ghez and Reinhard Genzel were honored by the Nobel Prize 2020.
