On the shores of the Milky Way they have found a ring of stars that I had not seen until now. This discovery can help explain how the Milky Way emerged. At the same time, this would show that part of our galaxy is made up of fragments of other galaxies. In addition, according to researchers, the position of the ring is ideal to investigate the dark matter between the Milky Way and the ring. The gravity force that causes this dark matter holds the ring.
