This is called Sagittarius A*. A black hole of 4 million solar mass located at 26,000 light-years from Earth at the centre of Milky Way Galaxy. The 2020 Nobel Prize in physics went to Roger Penrose for the discovery that black hole formation is a robust prediction of the general theory of relativity, a half-share also went to Reinhard Genzel and Andrea Ghez for the discovery of a supermassive compact object at the centre of our galaxy. These are the only places where Universe comes to an end, i.e. parts of the Universe disapear forever.
